// 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 as templates cannot be
// declared inside of a local class.
// Users can, however, define any local functors (e.g. a lambda) that
// can be used as actions.
//

// Google Mock - a framework for writing C++ mock classes.
//
// The MATCHER* family of macros can be used in a namespace scope to
// define custom matchers easily.
//
// Basic Usage
// ===========
//
// The syntax
//
// MATCHER(name, description_string) { statements; }
//
// defines a matcher with the given name that executes the statements,
// which must return a bool to indicate if the match succeeds. 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_P$n 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 as templates cannot be
// declared inside of a local class.
//
// More Information
// ================
//
// To learn more about using these macros, please search for 'MATCHER'
// on
// https://github.com/google/googletest/blob/master/docs/gmock_cook_book.md
//
// This file also implements some commonly used argument matchers. More
// matchers can be defined by the user implementing the
// MatcherInterface<T> interface if necessary.
//
// See googletest/include/gtest/gtest-matchers.h for the definition of class
// Matcher, class MatcherInterface, and others.

//
// TEST(FooTest, InvokesBarCorrectly) {
// MyMock mock;
// MockFunction<void(string check_point_name)> check;
// {
// InSequence s;
//
// EXPECT_CALL(mock, Bar("a"));
// EXPECT_CALL(check, Call("1"));
// EXPECT_CALL(check, Call("2"));
// EXPECT_CALL(mock, Bar("a"));
// }
// Foo(1);
// check.Call("1");
// Foo(2);
// check.Call("2");
// Foo(3);
// }
//
// The expectation spec says that the first Bar("a") must happen
// before check point "1", the second Bar("a") must happen after check
// point "2", and nothing should happen between the two check
// points. The explicit check points make it easy to tell which
// Bar("a") is called by which call to Foo().
//
// MockFunction<F> can also be used to exercise code that accepts
// std::function<internal::SignatureOfT<F>> callbacks. To do so, use
// AsStdFunction() method to create std::function proxy forwarding to
// original object's Call. Example:
//
// TEST(FooTest, RunsCallbackWithBarArgument) {
// MockFunction<int(string)> callback;
// EXPECT_CALL(callback, Call("bar")).WillOnce(Return(1));
// Foo(callback.AsStdFunction());
// }
//
// The internal::SignatureOfT<F> indirection allows to use other types
// than just function signature type. This is typically useful when
// providing a mock for a predefined std::function type. Example:
//
// using FilterPredicate = std::function<bool(string)>;
// void MyFilterAlgorithm(FilterPredicate predicate);
//
// TEST(FooTest, FilterPredicateAlwaysAccepts) {
// MockFunction<FilterPredicate> predicateMock;
// EXPECT_CALL(predicateMock, Call(_)).WillRepeatedly(Return(true));
// MyFilterAlgorithm(predicateMock.AsStdFunction());
// }

// Implementation for ON_CALL and EXPECT_CALL macros. A separate macro is
// required to avoid compile errors when the name of the method used in call is
// a result of macro expansion. See CompilesWithMethodNameExpandedFromMacro
// tests in internal/gmock-spec-builders_test.cc for more details.
//
// This macro supports statements both with and without parameter matchers. If
// the parameter list is omitted, gMock will accept any parameters, which allows
// tests to be written that don't need to encode the number of method
// parameter. 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! Which overload did you want?
// ON_CALL(mock, OverloadedMethod).WillByDefault(...);
// => ERROR: call to member function 'gmock_OverloadedMethod' is ambiguous
//
// How this works: The mock class uses two overloads of the gmock_Method
// expectation setter method plus an operator() overload on the MockSpec object.
// In the matcher list form, the macro expands to:
//
// // This statement:
// ON_CALL(mock, TwoArgsMethod(_, 45))...
//
// // ...expands to:
// mock.gmock_TwoArgsMethod(_, 45)(WithoutMatchers(), nullptr)...
// |-------------v---------------||------------v-------------|
// invokes first overload swallowed by operator()
//
// // ...which is essentially:
// mock.gmock_TwoArgsMethod(_, 45)...
//
// Whereas the form without a matcher list:
//
// // This statement:
// ON_CALL(mock, TwoArgsMethod)...
//
// // ...expands to:
// mock.gmock_TwoArgsMethod(WithoutMatchers(), nullptr)...
// |-----------------------v--------------------------|
// invokes second overload
//
// // ...which is essentially:
// mock.gmock_TwoArgsMethod(_, _)...
//
// The WithoutMatchers() argument is used to disambiguate overloads and to
// block the caller from accidentally invoking the second overload directly. The
// second argument is an internal type derived from the method signature. The
// failure to disambiguate two overloads of this method in the ON_CALL statement
// is how we block callers from setting expectations on overloaded methods.

// 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. The value argument types are inferred by the compiler.
// If you want to explicitly specify the value argument types, you can
// provide additional template arguments:
//
// ActionName<t1, ..., t_m, u1, ..., u_k>(v1, ..., v_n)
//
// where u_i is the desired type of v_i.
//
// ACTION_TEMPLATE and ACTION/ACTION_P* can be overloaded on the
// number of value parameters, but not on the number of template
// parameters. 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.

// argument of the mock function takes a const string&, the action
//
// InvokeArgument<0>(string("Hello"))
//
// makes a copy of the temporary string("Hello") object and passes a

// to the callable. This makes it easy for a user to define an
// InvokeArgument action from temporary values and have it performed

// Implements class templates NiceMock, NaggyMock, and StrictMock.
//
// Given a mock class MockFoo that is created using Google Mock,
// NiceMock<MockFoo> is a subclass of MockFoo that allows
// uninteresting calls (i.e. calls to mock methods that have no
// EXPECT_CALL specs), NaggyMock<MockFoo> is a subclass of MockFoo
// that prints a warning when an uninteresting call occurs, and
// StrictMock<MockFoo> is a subclass of MockFoo that treats all
// uninteresting calls as errors.
//
// Currently a mock is naggy by default, so MockFoo and
// NaggyMock<MockFoo> behave like the same. However, we will soon
// switch the default behavior of mocks to be nice, as that in general
// leads to more maintainable tests. When that happens, MockFoo will
// stop behaving like NaggyMock<MockFoo> and start behaving like
// NiceMock<MockFoo>.
//
// NiceMock, NaggyMock, and StrictMock "inherit" the constructors of
// their respective base class. Therefore you can write
// NiceMock<MockFoo>(5, "a") to construct a nice mock where MockFoo
// has a constructor that accepts (int, const char*), for example.
//
// A known limitation is that NiceMock<MockFoo>, NaggyMock<MockFoo>,
// and StrictMock<MockFoo> only works for mock methods defined using
// the MOCK_METHOD* family of macros DIRECTLY in the MockFoo class.
// If a mock method is defined in a base class of MockFoo, the "nice"
// or "strict" modifier may not affect it, depending on the compiler.
// In particular, nesting NiceMock, NaggyMock, and StrictMock is NOT
// supported.
