-# Defining a Mock Class #
-
-## Mocking a Normal Class ##
-
-Given
-```
-class Foo {
- ...
- virtual ~Foo();
- virtual int GetSize() const = 0;
- virtual string Describe(const char* name) = 0;
- virtual string Describe(int type) = 0;
- virtual bool Process(Bar elem, int count) = 0;
-};
-```
-(note that `~Foo()` **must** be virtual) we can define its mock as
-```
-#include "gmock/gmock.h"
-
-class MockFoo : public Foo {
- MOCK_CONST_METHOD0(GetSize, int());
- MOCK_METHOD1(Describe, string(const char* name));
- MOCK_METHOD1(Describe, string(int type));
- MOCK_METHOD2(Process, bool(Bar elem, int count));
-};
-```
-
-To create a "nice" mock object which ignores all uninteresting calls,
-or a "strict" mock object, which treats them as failures:
-```
-NiceMock<MockFoo> nice_foo; // The type is a subclass of MockFoo.
-StrictMock<MockFoo> strict_foo; // The type is a subclass of MockFoo.
-```
-
-## Mocking a Class Template ##
-
-To mock
-```
-template <typename Elem>
-class StackInterface {
- public:
- ...
- virtual ~StackInterface();
- virtual int GetSize() const = 0;
- virtual void Push(const Elem& x) = 0;
-};
-```
-(note that `~StackInterface()` **must** be virtual) just append `_T` to the `MOCK_*` macros:
-```
-template <typename Elem>
-class MockStack : public StackInterface<Elem> {
- public:
- ...
- MOCK_CONST_METHOD0_T(GetSize, int());
- MOCK_METHOD1_T(Push, void(const Elem& x));
-};
-```
-
-## Specifying Calling Conventions for Mock Functions ##
-
-If your mock function doesn't use the default calling convention, you
-can specify it by appending `_WITH_CALLTYPE` to any of the macros
-described in the previous two sections and supplying the calling
-convention as the first argument to the macro. For example,
-```
- MOCK_METHOD_1_WITH_CALLTYPE(STDMETHODCALLTYPE, Foo, bool(int n));
- MOCK_CONST_METHOD2_WITH_CALLTYPE(STDMETHODCALLTYPE, Bar, int(double x, double y));
-```
-where `STDMETHODCALLTYPE` is defined by `<objbase.h>` on Windows.
-
-# Using Mocks in Tests #
-
-The typical flow is:
- 1. Import the Google Mock names you need to use. All Google Mock names are in the `testing` namespace unless they are macros or otherwise noted.
- 1. Create the mock objects.
- 1. Optionally, set the default actions of the mock objects.
- 1. Set your expectations on the mock objects (How will they be called? What wil they do?).
- 1. Exercise code that uses the mock objects; if necessary, check the result using [Google Test](http://code.google.com/p/googletest/) assertions.
- 1. When a mock objects is destructed, Google Mock automatically verifies that all expectations on it have been satisfied.
-
-Here is an example:
-```
-using ::testing::Return; // #1
-
-TEST(BarTest, DoesThis) {
- MockFoo foo; // #2
-
- ON_CALL(foo, GetSize()) // #3
- .WillByDefault(Return(1));
- // ... other default actions ...
-
- EXPECT_CALL(foo, Describe(5)) // #4
- .Times(3)
- .WillRepeatedly(Return("Category 5"));
- // ... other expectations ...
-
- EXPECT_EQ("good", MyProductionFunction(&foo)); // #5
-} // #6
-```
-
-# Setting Default Actions #
-
-Google Mock has a **built-in default action** for any function that
-returns `void`, `bool`, a numeric value, or a pointer.
-
-To customize the default action for functions with return type `T` globally:
-```
-using ::testing::DefaultValue;
-
-DefaultValue<T>::Set(value); // Sets the default value to be returned.
-// ... use the mocks ...
-DefaultValue<T>::Clear(); // Resets the default value.
-```
-
-To customize the default action for a particular method, use `ON_CALL()`:
-```
-ON_CALL(mock_object, method(matchers))
- .With(multi_argument_matcher) ?
- .WillByDefault(action);
-```
-
-# Setting Expectations #
-
-`EXPECT_CALL()` sets **expectations** on a mock method (How will it be
-called? What will it do?):
-```
-EXPECT_CALL(mock_object, method(matchers))
- .With(multi_argument_matcher) ?
- .Times(cardinality) ?
- .InSequence(sequences) *
- .After(expectations) *
- .WillOnce(action) *
- .WillRepeatedly(action) ?
- .RetiresOnSaturation(); ?
-```
-
-If `Times()` is omitted, the cardinality is assumed to be:
-
- * `Times(1)` when there is neither `WillOnce()` nor `WillRepeatedly()`;
- * `Times(n)` when there are `n WillOnce()`s but no `WillRepeatedly()`, where `n` >= 1; or
- * `Times(AtLeast(n))` when there are `n WillOnce()`s and a `WillRepeatedly()`, where `n` >= 0.
-
-A method with no `EXPECT_CALL()` is free to be invoked _any number of times_, and the default action will be taken each time.
-
-# Matchers #
-
-A **matcher** matches a _single_ argument. You can use it inside
-`ON_CALL()` or `EXPECT_CALL()`, or use it to validate a value
-directly:
-
-| `EXPECT_THAT(value, matcher)` | Asserts that `value` matches `matcher`. |
-|:------------------------------|:----------------------------------------|
-| `ASSERT_THAT(value, matcher)` | The same as `EXPECT_THAT(value, matcher)`, except that it generates a **fatal** failure. |
-
-Built-in matchers (where `argument` is the function argument) are
-divided into several categories:
-
-## Wildcard ##
-|`_`|`argument` can be any value of the correct type.|
-|:--|:-----------------------------------------------|
-|`A<type>()` or `An<type>()`|`argument` can be any value of type `type`. |
-
-## Generic Comparison ##
-
-|`Eq(value)` or `value`|`argument == value`|
-|:---------------------|:------------------|
-|`Ge(value)` |`argument >= value`|
-|`Gt(value)` |`argument > value` |
-|`Le(value)` |`argument <= value`|
-|`Lt(value)` |`argument < value` |
-|`Ne(value)` |`argument != value`|
-|`IsNull()` |`argument` is a `NULL` pointer (raw or smart).|
-|`NotNull()` |`argument` is a non-null pointer (raw or smart).|
-|`Ref(variable)` |`argument` is a reference to `variable`.|
-|`TypedEq<type>(value)`|`argument` has type `type` and is equal to `value`. You may need to use this instead of `Eq(value)` when the mock function is overloaded.|
-
-Except `Ref()`, these matchers make a _copy_ of `value` in case it's
-modified or destructed later. If the compiler complains that `value`
-doesn't have a public copy constructor, try wrap it in `ByRef()`,
-e.g. `Eq(ByRef(non_copyable_value))`. If you do that, make sure
-`non_copyable_value` is not changed afterwards, or the meaning of your
-matcher will be changed.
-
-## Floating-Point Matchers ##
-
-|`DoubleEq(a_double)`|`argument` is a `double` value approximately equal to `a_double`, treating two NaNs as unequal.|
-|:-------------------|:----------------------------------------------------------------------------------------------|
-|`FloatEq(a_float)` |`argument` is a `float` value approximately equal to `a_float`, treating two NaNs as unequal. |
-|`NanSensitiveDoubleEq(a_double)`|`argument` is a `double` value approximately equal to `a_double`, treating two NaNs as equal. |
-|`NanSensitiveFloatEq(a_float)`|`argument` is a `float` value approximately equal to `a_float`, treating two NaNs as equal. |
-
-The above matchers use ULP-based comparison (the same as used in
-[Google Test](http://code.google.com/p/googletest/)). They
-automatically pick a reasonable error bound based on the absolute
-value of the expected value. `DoubleEq()` and `FloatEq()` conform to
-the IEEE standard, which requires comparing two NaNs for equality to
-return false. The `NanSensitive*` version instead treats two NaNs as
-equal, which is often what a user wants.
-
-|`DoubleNear(a_double, max_abs_error)`|`argument` is a `double` value close to `a_double` (absolute error <= `max_abs_error`), treating two NaNs as unequal.|
-|:------------------------------------|:--------------------------------------------------------------------------------------------------------------------|
-|`FloatNear(a_float, max_abs_error)` |`argument` is a `float` value close to `a_float` (absolute error <= `max_abs_error`), treating two NaNs as unequal. |
-|`NanSensitiveDoubleNear(a_double, max_abs_error)`|`argument` is a `double` value close to `a_double` (absolute error <= `max_abs_error`), treating two NaNs as equal. |
-|`NanSensitiveFloatNear(a_float, max_abs_error)`|`argument` is a `float` value close to `a_float` (absolute error <= `max_abs_error`), treating two NaNs as equal. |
-
-## String Matchers ##
-
-The `argument` can be either a C string or a C++ string object:
-
-|`ContainsRegex(string)`|`argument` matches the given regular expression.|
-|:----------------------|:-----------------------------------------------|
-|`EndsWith(suffix)` |`argument` ends with string `suffix`. |
-|`HasSubstr(string)` |`argument` contains `string` as a sub-string. |
-|`MatchesRegex(string)` |`argument` matches the given regular expression with the match starting at the first character and ending at the last character.|
-|`StartsWith(prefix)` |`argument` starts with string `prefix`. |
-|`StrCaseEq(string)` |`argument` is equal to `string`, ignoring case. |
-|`StrCaseNe(string)` |`argument` is not equal to `string`, ignoring case.|
-|`StrEq(string)` |`argument` is equal to `string`. |
-|`StrNe(string)` |`argument` is not equal to `string`. |
-
-`ContainsRegex()` and `MatchesRegex()` use the regular expression
-syntax defined
-[here](http://code.google.com/p/googletest/wiki/AdvancedGuide#Regular_Expression_Syntax).
-`StrCaseEq()`, `StrCaseNe()`, `StrEq()`, and `StrNe()` work for wide
-strings as well.
-
-## Container Matchers ##
-
-Most STL-style containers support `==`, so you can use
-`Eq(expected_container)` or simply `expected_container` to match a
-container exactly. If you want to write the elements in-line,
-match them more flexibly, or get more informative messages, you can use:
-
-| `ContainerEq(container)` | The same as `Eq(container)` except that the failure message also includes which elements are in one container but not the other. |
-|:-------------------------|:---------------------------------------------------------------------------------------------------------------------------------|
-| `Contains(e)` | `argument` contains an element that matches `e`, which can be either a value or a matcher. |
-| `Each(e)` | `argument` is a container where _every_ element matches `e`, which can be either a value or a matcher. |
-| `ElementsAre(e0, e1, ..., en)` | `argument` has `n + 1` elements, where the i-th element matches `ei`, which can be a value or a matcher. 0 to 10 arguments are allowed. |
-| `ElementsAreArray({ e0, e1, ..., en })`, `ElementsAreArray(array)`, or `ElementsAreArray(array, count)` | The same as `ElementsAre()` except that the expected element values/matchers come from an initializer list, vector, or C-style array. |
-| `IsEmpty()` | `argument` is an empty container (`container.empty()`). |
-| `Pointwise(m, container)` | `argument` contains the same number of elements as in `container`, and for all i, (the i-th element in `argument`, the i-th element in `container`) match `m`, which is a matcher on 2-tuples. E.g. `Pointwise(Le(), upper_bounds)` verifies that each element in `argument` doesn't exceed the corresponding element in `upper_bounds`. See more detail below. |
-| `SizeIs(m)` | `argument` is a container whose size matches `m`. E.g. `SizeIs(2)` or `SizeIs(Lt(2))`. |
-| `UnorderedElementsAre(e0, e1, ..., en)` | `argument` has `n + 1` elements, and under some permutation each element matches an `ei` (for a different `i`), which can be a value or a matcher. 0 to 10 arguments are allowed. |
-| `UnorderedElementsAreArray({ e0, e1, ..., en })`, `UnorderedElementsAreArray(array)`, or `UnorderedElementsAreArray(array, count)` | The same as `UnorderedElementsAre()` except that the expected element values/matchers come from an initializer list, vector, or C-style array. |
-| `WhenSorted(m)` | When `argument` is sorted using the `<` operator, it matches container matcher `m`. E.g. `WhenSorted(UnorderedElementsAre(1, 2, 3))` verifies that `argument` contains elements `1`, `2`, and `3`, ignoring order. |
-| `WhenSortedBy(comparator, m)` | The same as `WhenSorted(m)`, except that the given comparator instead of `<` is used to sort `argument`. E.g. `WhenSortedBy(std::greater<int>(), ElementsAre(3, 2, 1))`. |
-
-Notes:
-
- * These matchers can also match:
- 1. a native array passed by reference (e.g. in `Foo(const int (&a)[5])`), and
- 1. an array passed as a pointer and a count (e.g. in `Bar(const T* buffer, int len)` -- see [Multi-argument Matchers](#Multiargument_Matchers.md)).
- * The array being matched may be multi-dimensional (i.e. its elements can be arrays).
- * `m` in `Pointwise(m, ...)` should be a matcher for `std::tr1::tuple<T, U>` where `T` and `U` are the element type of the actual container and the expected container, respectively. For example, to compare two `Foo` containers where `Foo` doesn't support `operator==` but has an `Equals()` method, one might write:
-
-```
-using ::std::tr1::get;
-MATCHER(FooEq, "") {
- return get<0>(arg).Equals(get<1>(arg));
-}
-...
-EXPECT_THAT(actual_foos, Pointwise(FooEq(), expected_foos));
-```
-
-## Member Matchers ##
-
-|`Field(&class::field, m)`|`argument.field` (or `argument->field` when `argument` is a plain pointer) matches matcher `m`, where `argument` is an object of type _class_.|
-|:------------------------|:---------------------------------------------------------------------------------------------------------------------------------------------|
-|`Key(e)` |`argument.first` matches `e`, which can be either a value or a matcher. E.g. `Contains(Key(Le(5)))` can verify that a `map` contains a key `<= 5`.|
-|`Pair(m1, m2)` |`argument` is an `std::pair` whose `first` field matches `m1` and `second` field matches `m2`. |
-|`Property(&class::property, m)`|`argument.property()` (or `argument->property()` when `argument` is a plain pointer) matches matcher `m`, where `argument` is an object of type _class_.|
-
-## Matching the Result of a Function or Functor ##
-
-|`ResultOf(f, m)`|`f(argument)` matches matcher `m`, where `f` is a function or functor.|
-|:---------------|:---------------------------------------------------------------------|
-
-## Pointer Matchers ##
-
-|`Pointee(m)`|`argument` (either a smart pointer or a raw pointer) points to a value that matches matcher `m`.|
-|:-----------|:-----------------------------------------------------------------------------------------------|
-
-## Multiargument Matchers ##
-
-Technically, all matchers match a _single_ value. A "multi-argument"
-matcher is just one that matches a _tuple_. The following matchers can
-be used to match a tuple `(x, y)`:
-
-|`Eq()`|`x == y`|
-|:-----|:-------|
-|`Ge()`|`x >= y`|
-|`Gt()`|`x > y` |
-|`Le()`|`x <= y`|
-|`Lt()`|`x < y` |
-|`Ne()`|`x != y`|
-
-You can use the following selectors to pick a subset of the arguments
-(or reorder them) to participate in the matching:
-
-|`AllArgs(m)`|Equivalent to `m`. Useful as syntactic sugar in `.With(AllArgs(m))`.|
-|:-----------|:-------------------------------------------------------------------|
-|`Args<N1, N2, ..., Nk>(m)`|The tuple of the `k` selected (using 0-based indices) arguments matches `m`, e.g. `Args<1, 2>(Eq())`.|
-
-## Composite Matchers ##
-
-You can make a matcher from one or more other matchers:
-
-|`AllOf(m1, m2, ..., mn)`|`argument` matches all of the matchers `m1` to `mn`.|
-|:-----------------------|:---------------------------------------------------|
-|`AnyOf(m1, m2, ..., mn)`|`argument` matches at least one of the matchers `m1` to `mn`.|
-|`Not(m)` |`argument` doesn't match matcher `m`. |
-
-## Adapters for Matchers ##
-
-|`MatcherCast<T>(m)`|casts matcher `m` to type `Matcher<T>`.|
-|:------------------|:--------------------------------------|
-|`SafeMatcherCast<T>(m)`| [safely casts](http://code.google.com/p/googlemock/wiki/V1_7_CookBook#Casting_Matchers) matcher `m` to type `Matcher<T>`. |
-|`Truly(predicate)` |`predicate(argument)` returns something considered by C++ to be true, where `predicate` is a function or functor.|
-
-## Matchers as Predicates ##
-
-|`Matches(m)(value)`|evaluates to `true` if `value` matches `m`. You can use `Matches(m)` alone as a unary functor.|
-|:------------------|:---------------------------------------------------------------------------------------------|
-|`ExplainMatchResult(m, value, result_listener)`|evaluates to `true` if `value` matches `m`, explaining the result to `result_listener`. |
-|`Value(value, m)` |evaluates to `true` if `value` matches `m`. |
-
-## Defining Matchers ##
-
-| `MATCHER(IsEven, "") { return (arg % 2) == 0; }` | Defines a matcher `IsEven()` to match an even number. |
-|:-------------------------------------------------|:------------------------------------------------------|
-| `MATCHER_P(IsDivisibleBy, n, "") { *result_listener << "where the remainder is " << (arg % n); return (arg % n) == 0; }` | Defines a macher `IsDivisibleBy(n)` to match a number divisible by `n`. |
-| `MATCHER_P2(IsBetween, a, b, std::string(negation ? "isn't" : "is") + " between " + PrintToString(a) + " and " + PrintToString(b)) { return a <= arg && arg <= b; }` | Defines a matcher `IsBetween(a, b)` to match a value in the range [`a`, `b`]. |
-
-**Notes:**
-
- 1. The `MATCHER*` macros cannot be used inside a function or class.
- 1. The matcher body must be _purely functional_ (i.e. it cannot have any side effect, and the result must not depend on anything other than the value being matched and the matcher parameters).
- 1. You can use `PrintToString(x)` to convert a value `x` of any type to a string.
-
-## Matchers as Test Assertions ##
-
-|`ASSERT_THAT(expression, m)`|Generates a [fatal failure](http://code.google.com/p/googletest/wiki/Primer#Assertions) if the value of `expression` doesn't match matcher `m`.|
-|:---------------------------|:----------------------------------------------------------------------------------------------------------------------------------------------|
-|`EXPECT_THAT(expression, m)`|Generates a non-fatal failure if the value of `expression` doesn't match matcher `m`. |
-
-# Actions #
-
-**Actions** specify what a mock function should do when invoked.
-
-## Returning a Value ##
-
-|`Return()`|Return from a `void` mock function.|
-|:---------|:----------------------------------|
-|`Return(value)`|Return `value`. If the type of `value` is different to the mock function's return type, `value` is converted to the latter type <i>at the time the expectation is set</i>, not when the action is executed.|
-|`ReturnArg<N>()`|Return the `N`-th (0-based) argument.|
-|`ReturnNew<T>(a1, ..., ak)`|Return `new T(a1, ..., ak)`; a different object is created each time.|
-|`ReturnNull()`|Return a null pointer. |
-|`ReturnPointee(ptr)`|Return the value pointed to by `ptr`.|
-|`ReturnRef(variable)`|Return a reference to `variable`. |
-|`ReturnRefOfCopy(value)`|Return a reference to a copy of `value`; the copy lives as long as the action.|
-
-## Side Effects ##
-
-|`Assign(&variable, value)`|Assign `value` to variable.|
-|:-------------------------|:--------------------------|
-| `DeleteArg<N>()` | Delete the `N`-th (0-based) argument, which must be a pointer. |
-| `SaveArg<N>(pointer)` | Save the `N`-th (0-based) argument to `*pointer`. |
-| `SaveArgPointee<N>(pointer)` | Save the value pointed to by the `N`-th (0-based) argument to `*pointer`. |
-| `SetArgReferee<N>(value)` | Assign value to the variable referenced by the `N`-th (0-based) argument. |
-|`SetArgPointee<N>(value)` |Assign `value` to the variable pointed by the `N`-th (0-based) argument.|
-|`SetArgumentPointee<N>(value)`|Same as `SetArgPointee<N>(value)`. Deprecated. Will be removed in v1.7.0.|
-|`SetArrayArgument<N>(first, last)`|Copies the elements in source range [`first`, `last`) to the array pointed to by the `N`-th (0-based) argument, which can be either a pointer or an iterator. The action does not take ownership of the elements in the source range.|
-|`SetErrnoAndReturn(error, value)`|Set `errno` to `error` and return `value`.|
-|`Throw(exception)` |Throws the given exception, which can be any copyable value. Available since v1.1.0.|
-
-## Using a Function or a Functor as an Action ##
-
-|`Invoke(f)`|Invoke `f` with the arguments passed to the mock function, where `f` can be a global/static function or a functor.|
-|:----------|:-----------------------------------------------------------------------------------------------------------------|
-|`Invoke(object_pointer, &class::method)`|Invoke the {method on the object with the arguments passed to the mock function. |
-|`InvokeWithoutArgs(f)`|Invoke `f`, which can be a global/static function or a functor. `f` must take no arguments. |
-|`InvokeWithoutArgs(object_pointer, &class::method)`|Invoke the method on the object, which takes no arguments. |
-|`InvokeArgument<N>(arg1, arg2, ..., argk)`|Invoke the mock function's `N`-th (0-based) argument, which must be a function or a functor, with the `k` arguments.|
-
-The return value of the invoked function is used as the return value
-of the action.
-
-When defining a function or functor to be used with `Invoke*()`, you can declare any unused parameters as `Unused`:
-```
- double Distance(Unused, double x, double y) { return sqrt(x*x + y*y); }
- ...
- EXPECT_CALL(mock, Foo("Hi", _, _)).WillOnce(Invoke(Distance));
-```
-
-In `InvokeArgument<N>(...)`, if an argument needs to be passed by reference, wrap it inside `ByRef()`. For example,
-```
- InvokeArgument<2>(5, string("Hi"), ByRef(foo))
-```
-calls the mock function's #2 argument, passing to it `5` and `string("Hi")` by value, and `foo` by reference.
-
-## Default Action ##
-
-|`DoDefault()`|Do the default action (specified by `ON_CALL()` or the built-in one).|
-|:------------|:--------------------------------------------------------------------|
-
-**Note:** due to technical reasons, `DoDefault()` cannot be used inside a composite action - trying to do so will result in a run-time error.
-
-## Composite Actions ##
-
-|`DoAll(a1, a2, ..., an)`|Do all actions `a1` to `an` and return the result of `an` in each invocation. The first `n - 1` sub-actions must return void. |
-|:-----------------------|:-----------------------------------------------------------------------------------------------------------------------------|
-|`IgnoreResult(a)` |Perform action `a` and ignore its result. `a` must not return void. |
-|`WithArg<N>(a)` |Pass the `N`-th (0-based) argument of the mock function to action `a` and perform it. |
-|`WithArgs<N1, N2, ..., Nk>(a)`|Pass the selected (0-based) arguments of the mock function to action `a` and perform it. |
-|`WithoutArgs(a)` |Perform action `a` without any arguments. |
-
-## Defining Actions ##
-
-| `ACTION(Sum) { return arg0 + arg1; }` | Defines an action `Sum()` to return the sum of the mock function's argument #0 and #1. |
-|:--------------------------------------|:---------------------------------------------------------------------------------------|
-| `ACTION_P(Plus, n) { return arg0 + n; }` | Defines an action `Plus(n)` to return the sum of the mock function's argument #0 and `n`. |
-| `ACTION_Pk(Foo, p1, ..., pk) { statements; }` | Defines a parameterized action `Foo(p1, ..., pk)` to execute the given `statements`. |
-
-The `ACTION*` macros cannot be used inside a function or class.
-
-# Cardinalities #
-
-These are used in `Times()` to specify how many times a mock function will be called:
-
-|`AnyNumber()`|The function can be called any number of times.|
-|:------------|:----------------------------------------------|
-|`AtLeast(n)` |The call is expected at least `n` times. |
-|`AtMost(n)` |The call is expected at most `n` times. |
-|`Between(m, n)`|The call is expected between `m` and `n` (inclusive) times.|
-|`Exactly(n) or n`|The call is expected exactly `n` times. In particular, the call should never happen when `n` is 0.|
-
-# Expectation Order #
-
-By default, the expectations can be matched in _any_ order. If some
-or all expectations must be matched in a given order, there are two
-ways to specify it. They can be used either independently or
-together.
-
-## The After Clause ##
-
-```
-using ::testing::Expectation;
-...
-Expectation init_x = EXPECT_CALL(foo, InitX());
-Expectation init_y = EXPECT_CALL(foo, InitY());
-EXPECT_CALL(foo, Bar())
- .After(init_x, init_y);
-```
-says that `Bar()` can be called only after both `InitX()` and
-`InitY()` have been called.
-
-If you don't know how many pre-requisites an expectation has when you
-write it, you can use an `ExpectationSet` to collect them:
-
-```
-using ::testing::ExpectationSet;
-...
-ExpectationSet all_inits;
-for (int i = 0; i < element_count; i++) {
- all_inits += EXPECT_CALL(foo, InitElement(i));
-}
-EXPECT_CALL(foo, Bar())
- .After(all_inits);
-```
-says that `Bar()` can be called only after all elements have been
-initialized (but we don't care about which elements get initialized
-before the others).
-
-Modifying an `ExpectationSet` after using it in an `.After()` doesn't
-affect the meaning of the `.After()`.
-
-## Sequences ##
-
-When you have a long chain of sequential expectations, it's easier to
-specify the order using **sequences**, which don't require you to given
-each expectation in the chain a different name. <i>All expected<br>
-calls</i> in the same sequence must occur in the order they are
-specified.
-
-```
-using ::testing::Sequence;
-Sequence s1, s2;
-...
-EXPECT_CALL(foo, Reset())
- .InSequence(s1, s2)
- .WillOnce(Return(true));
-EXPECT_CALL(foo, GetSize())
- .InSequence(s1)
- .WillOnce(Return(1));
-EXPECT_CALL(foo, Describe(A<const char*>()))
- .InSequence(s2)
- .WillOnce(Return("dummy"));
-```
-says that `Reset()` must be called before _both_ `GetSize()` _and_
-`Describe()`, and the latter two can occur in any order.
-
-To put many expectations in a sequence conveniently:
-```
-using ::testing::InSequence;
-{
- InSequence dummy;
-
- EXPECT_CALL(...)...;
- EXPECT_CALL(...)...;
- ...
- EXPECT_CALL(...)...;
-}
-```
-says that all expected calls in the scope of `dummy` must occur in
-strict order. The name `dummy` is irrelevant.)
-
-# Verifying and Resetting a Mock #
-
-Google Mock will verify the expectations on a mock object when it is destructed, or you can do it earlier:
-```
-using ::testing::Mock;
-...
-// Verifies and removes the expectations on mock_obj;
-// returns true iff successful.
-Mock::VerifyAndClearExpectations(&mock_obj);
-...
-// Verifies and removes the expectations on mock_obj;
-// also removes the default actions set by ON_CALL();
-// returns true iff successful.
-Mock::VerifyAndClear(&mock_obj);
-```
-
-You can also tell Google Mock that a mock object can be leaked and doesn't
-need to be verified:
-```
-Mock::AllowLeak(&mock_obj);
-```
-
-# Mock Classes #
-
-Google Mock defines a convenient mock class template
-```
-class MockFunction<R(A1, ..., An)> {
- public:
- MOCK_METHODn(Call, R(A1, ..., An));
-};
-```
-See this [recipe](http://code.google.com/p/googlemock/wiki/V1_7_CookBook#Using_Check_Points) for one application of it.
