This technique may only be used for non-overloaded methods.////   // These are the same://   ON_CALL(mock, NoArgsMethod()).WillByDefault(...);//   ON_CALL(mock, NoArgsMethod).WillByDefault(...);////   // As are these://   ON_CALL(mock, TwoArgsMethod(_, _)).WillByDefault(...);//   ON_CALL(mock, TwoArgsMethod).WillByDefault(...);////   // Can also specify args if you want, of course://   ON_CALL(mock, TwoArgsMethod(_, 45)).WillByDefault(...);////   // Overloads work as long as you specify parameters://   ON_CALL(mock, OverloadedMethod(_)).WillByDefault(...);//   ON_CALL(mock, OverloadedMethod(_, _)).WillByDefault(...);////   // Oops!

 }};}  // namespace internal}  // namespace testing// The ACTION* family of macros can be used in a namespace scope to// define custom actions easily.  The syntax:////   ACTION(name) { statements; }//// will define an action with the given name that executes the// statements.  The value returned by the statements will be used as// the return value of the action.  Inside the statements, you can// refer to the K-th (0-based) argument of the mock function by// 'argK', and refer to its type by 'argK_type'.  For example:////   ACTION(IncrementArg1) {//     arg1_type temp = arg1;//     return ++(*temp);//   }//// allows you to write////   ...WillOnce(IncrementArg1());//// You can also refer to the entire argument tuple and its type by// 'args' and 'args_type', and refer to the mock function type and its// return type by 'function_type' and 'return_type'.//// Note that you don't need to specify the types of the mock function// arguments.  However rest assured that your code is still type-safe:// you'll get a compiler error if *arg1 doesn't support the ++// operator, or if the type of ++(*arg1) isn't compatible with the// mock function's return type, for example.//// Sometimes you'll want to parameterize the action.   For that you can use// another macro:////   ACTION_P(name, param_name) { statements; }//// For example:////   ACTION_P(Add, n) { return arg0 + n; }//// will allow you to write:////   ...WillOnce(Add(5));//// Note that you don't need to provide the type of the parameter// either.  If you need to reference the type of a parameter named// 'foo', you can write 'foo_type'.  For example, in the body of// ACTION_P(Add, n) above, you can write 'n_type' to refer to the type// of 'n'.//// We also provide ACTION_P2, ACTION_P3, ..., up to ACTION_P10 to support// multi-parameter actions.//// For the purpose of typing, you can view////   ACTION_Pk(Foo, p1, ..., pk) { ... }//// as shorthand for////   template <typename p1_type, ..., typename pk_type>//   FooActionPk<p1_type, ..., pk_type> Foo(p1_type p1, ..., pk_type pk) { ... }//// In particular, you can provide the template type arguments// explicitly when invoking Foo(), as in Foo<long, bool>(5, false);// although usually you can rely on the compiler to infer the types// for you automatically.  You can assign the result of expression// Foo(p1, ..., pk) to a variable of type FooActionPk<p1_type, ...,// pk_type>.  This can be useful when composing actions.//// You can also overload actions with different numbers of parameters:////   ACTION_P(Plus, a) { ... }//   ACTION_P2(Plus, a, b) { ... }//// While it's tempting to always use the ACTION* macros when defining// a new action, you should also consider implementing ActionInterface// or using MakePolymorphicAction() instead, especially if you need to// use the action a lot.  While these approaches require more work,// they give you more control on the types of the mock function// arguments and the action parameters, which in general leads to// better compiler error messages that pay off in the long run.  They// also allow overloading actions based on parameter types (as opposed// to just based on the number of parameters).//// CAVEAT://// ACTION*() can only be used in a namespace scope.  The reason is// that C++ doesn't yet allow function-local types to be used to// instantiate templates.  The up-coming C++0x standard will fix this.// Once that's done, we'll consider supporting using ACTION*() inside// a function.//// MORE INFORMATION://// To learn more about using these macros, please search for 'ACTION' on// https://github.com/google/googletest/blob/master/googlemock/docs/CookBook.md// An internal macro needed for implementing ACTION*().#define GMOCK_ACTION_ARG_TYPES_AND_NAMES_UNUSED_\    const args_type& args GTEST_ATTRIBUTE_UNUSED_, \    arg0_type arg0 GTEST_ATTRIBUTE_UNUSED_, \    arg1_type arg1 GTEST_ATTRIBUTE_UNUSED_, \    arg2_type arg2 GTEST_ATTRIBUTE_UNUSED_, \    arg3_type arg3 GTEST_ATTRIBUTE_UNUSED_, \    arg4_type arg4 GTEST_ATTRIBUTE_UNUSED_, \    arg5_type arg5 GTEST_ATTRIBUTE_UNUSED_, \    arg6_type arg6 GTEST_ATTRIBUTE_UNUSED_, \    arg7_type arg7 GTEST_ATTRIBUTE_UNUSED_, \    arg8_type arg8 GTEST_ATTRIBUTE_UNUSED_, \    arg9_type arg9 GTEST_ATTRIBUTE_UNUSED_// Sometimes you want to give an action explicit template parameters// that cannot be inferred from its value parameters.  ACTION() and// ACTION_P*() don't support that.  ACTION_TEMPLATE() remedies that// and can be viewed as an extension to ACTION() and ACTION_P*().//// The syntax:////   ACTION_TEMPLATE(ActionName,//                   HAS_m_TEMPLATE_PARAMS(kind1, name1, ..., kind_m, name_m),//                   AND_n_VALUE_PARAMS(p1, ..., p_n)) { statements; }//// defines an action template that takes m explicit template// parameters and n value parameters.  name_i is the name of the i-th// template parameter, and kind_i specifies whether it's a typename,// an integral constant, or a template.  p_i is the name of the i-th// value parameter.//// Example:////   // DuplicateArg<k, T>(output) converts the k-th argument of the mock//   // function to type T and copies it to *output.//   ACTION_TEMPLATE(DuplicateArg,//                   HAS_2_TEMPLATE_PARAMS(int, k, typename, T),//                   AND_1_VALUE_PARAMS(output)) {//     *output = T(::std::get<k>(args));//   }//   ...//     int n;//     EXPECT_CALL(mock, Foo(_, _))//         .WillOnce(DuplicateArg<1, unsigned char>(&n));//// To create an instance of an action template, write:////   ActionName<t1, ..., t_m>(v1, ..., v_n)//// where the ts are the template arguments and the vs are the value// arguments.

Without the restriction, the meaning of the following// is unclear:////   OverloadedAction<int, bool>(x);//// Are we using a single-template-parameter action where 'bool' refers// to the type of x, or are we using a two-template-parameter action// where the compiler is asked to infer the type of x?//// Implementation notes://// GMOCK_INTERNAL_*_HAS_m_TEMPLATE_PARAMS and// GMOCK_INTERNAL_*_AND_n_VALUE_PARAMS are internal macros for// implementing ACTION_TEMPLATE.  The main trick we use is to create// new macro invocations when expanding a macro.  For example, we have////   #define ACTION_TEMPLATE(name, template_params, value_params)//       ... GMOCK_INTERNAL_DECL_##template_params ...//// which causes ACTION_TEMPLATE(..., HAS_1_TEMPLATE_PARAMS(typename, T), ...)// to expand to////       ... GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS(typename, T) ...//// Since GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS is a macro, the// preprocessor will continue to expand it to////       ... typename T ...//// This technique conforms to the C++ standard and is portable.  It// allows us to implement action templates using O(N) code, where N is// the maximum number of template/value parameters supported.  Without// using it, we'd have to devote O(N^2) amount of code to implement all// combinations of m and n.// Declares the template parameters.#define GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS(kind0,

The arguments are passed by value by default.  If you need to//   pass an argument by reference, wrap it inside ByRef().  For//   example,////     InvokeArgument<1>(5, string("Hello"), ByRef(foo))////   passes 5 and string("Hello") by value, and passes foo by//   reference.////   2. If the callable takes an argument by reference but ByRef() is//   not used, it will receive the reference to a copy of the value,//   instead of the original value.

Inside// the statements, you can refer to the value being matched by 'arg',// and refer to its type by 'arg_type'.//// The description string documents what the matcher does, and is used// to generate the failure message when the match fails.  Since a// MATCHER() is usually defined in a header file shared by multiple// C++ source files, we require the description to be a C-string// literal to avoid possible side effects.  It can be empty, in which// case we'll use the sequence of words in the matcher name as the// description.//// For example:////   MATCHER(IsEven, "") { return (arg % 2) == 0; }//// allows you to write////   // Expects mock_foo.Bar(n) to be called where n is even.//   EXPECT_CALL(mock_foo, Bar(IsEven()));//// or,////   // Verifies that the value of some_expression is even.//   EXPECT_THAT(some_expression, IsEven());//// If the above assertion fails, it will print something like:////   Value of: some_expression//   Expected: is even//     Actual: 7//// where the description "is even" is automatically calculated from the// matcher name IsEven.//// Argument Type// =============//// Note that the type of the value being matched (arg_type) is// determined by the context in which you use the matcher and is// supplied to you by the compiler, so you don't need to worry about// declaring it (nor can you).  This allows the matcher to be// polymorphic.  For example, IsEven() can be used to match any type// where the value of "(arg % 2) == 0" can be implicitly converted to// a bool.  In the "Bar(IsEven())" example above, if method Bar()// takes an int, 'arg_type' will be int; if it takes an unsigned long,// 'arg_type' will be unsigned long; and so on.//// Parameterizing Matchers// =======================//// Sometimes you'll want to parameterize the matcher.  For that you// can use another macro:////   MATCHER_P(name, param_name, description_string) { statements; }//// For example:////   MATCHER_P(HasAbsoluteValue, value, "") { return abs(arg) == value; }//// will allow you to write:////   EXPECT_THAT(Blah("a"), HasAbsoluteValue(n));//// which may lead to this message (assuming n is 10):////   Value of: Blah("a")//   Expected: has absolute value 10//     Actual: -9//// Note that both the matcher description and its parameter are// printed, making the message human-friendly.//// In the matcher definition body, you can write 'foo_type' to// reference the type of a parameter named 'foo'.  For example, in the// body of MATCHER_P(HasAbsoluteValue, value) above, you can write// 'value_type' to refer to the type of 'value'.//// We also provide MATCHER_P2, MATCHER_P3, ..., up to MATCHER_P10 to// support multi-parameter matchers.//// Describing Parameterized Matchers// =================================//// The last argument to MATCHER*() is a string-typed expression.  The// expression can reference all of the matcher's parameters and a// special bool-typed variable named 'negation'.  When 'negation' is// false, the expression should evaluate to the matcher's description;// otherwise it should evaluate to the description of the negation of// the matcher.  For example,////   using testing::PrintToString;////   MATCHER_P2(InClosedRange, low, hi,//       std::string(negation ? "is not" : "is") + " in range [" +//       PrintToString(low) + ", " + PrintToString(hi) + "]") {//     return low <= arg && arg <= hi;//   }//   ...//   EXPECT_THAT(3, InClosedRange(4, 6));//   EXPECT_THAT(3, Not(InClosedRange(2, 4)));//// would generate two failures that contain the text:////   Expected: is in range [4, 6]//   ...//   Expected: is not in range [2, 4]//// If you specify "" as the description, the failure message will// contain the sequence of words in the matcher name followed by the// parameter values printed as a tuple.  For example,////   MATCHER_P2(InClosedRange, low, hi, "") { ... }//   ...//   EXPECT_THAT(3, InClosedRange(4, 6));//   EXPECT_THAT(3, Not(InClosedRange(2, 4)));//// would generate two failures that contain the text:////   Expected: in closed range (4, 6)//   ...//   Expected: not (in closed range (2, 4))//// Types of Matcher Parameters// ===========================//// For the purpose of typing, you can view////   MATCHER_Pk(Foo, p1, ..., pk, description_string) { ... }//// as shorthand for////   template <typename p1_type, ..., typename pk_type>//   FooMatcherPk<p1_type, ..., pk_type>//   Foo(p1_type p1, ..., pk_type pk) { ... }//// When you write Foo(v1, ..., vk), the compiler infers the types of// the parameters v1, ..., and vk for you.  If you are not happy with// the result of the type inference, you can specify the types by// explicitly instantiating the template, as in Foo<long, bool>(5,// false).  As said earlier, you don't get to (or need to) specify// 'arg_type' as that's determined by the context in which the matcher// is used.  You can assign the result of expression Foo(p1, ..., pk)// to a variable of type FooMatcherPk<p1_type, ..., pk_type>.  This// can be useful when composing matchers.//// While you can instantiate a matcher template with reference types,// passing the parameters by pointer usually makes your code more// readable.  If, however, you still want to pass a parameter by// reference, be aware that in the failure message generated by the// matcher you will see the value of the referenced object but not its// address.//// Explaining Match Results// ========================//// Sometimes the matcher description alone isn't enough to explain why// the match has failed or succeeded.  For example, when expecting a// long string, it can be very helpful to also print the diff between// the expected string and the actual one.  To achieve that, you can// optionally stream additional information to a special variable// named result_listener, whose type is a pointer to class// MatchResultListener:////   MATCHER_P(EqualsLongString, str, "") {//     if (arg == str) return true;////     *result_listener << "the difference: "///                     << DiffStrings(str, arg);//     return false;//   }//// Overloading Matchers// ====================//// You can overload matchers with different numbers of parameters:////   MATCHER_P(Blah, a, description_string1) { ... }//   MATCHER_P2(Blah, a, b, description_string2) { ... }//// Caveats// =======//// When defining a new matcher, you should also consider implementing// MatcherInterface or using MakePolymorphicMatcher().  These// approaches require more work than the MATCHER* macros, but also// give you more control on the types of the value being matched and// the matcher parameters, which may leads to better compiler error// messages when the matcher is used wrong.  They also allow// overloading matchers based on parameter types (as opposed to just// based on the number of parameters).//// MATCHER*() can only be used in a namespace scope.  The reason is// that C++ doesn't yet allow function-local types to be used to// instantiate templates.  The up-coming C++0x standard will fix this.// Once that's done, we'll consider supporting using MATCHER*() inside// a function.//// More Information// ================//// To learn more about using
