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.

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.

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 these macros, please search for 'MATCHER' +// on +// https://github.com/google/googletest/blob/master/googlemock/docs/CookBook.md + +#define MATCHER(name, description)\ + class

It will not +$$ // show up in the generated code. + + +// 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. 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 these macros, please search for 'MATCHER' +// on +// https://github.com/google/googletest/blob/master/googlemock/docs/CookBook.md + +$range i 0..n +$for i + +[[ +$var macro_name = [[$if i==0 [[MATCHER]] $elif i==1 [[MATCHER_P]] + $else [[MATCHER_P$i]]]] +$var class_name = [[name##Matcher[[$if i==0 [[]] $elif i==1 [[P]] + $else [[P$i]]]]]] +$range j 0..i-1 +$var template = [[$if i==0 [[]] $else [[ + + template <$for j, [[typename p$j##_type]]>\ +]]]] +$var ctor_param_list = [[$for j, [[p$j##_type gmock_p$j]]]] +$var impl_ctor_param_list = [[$for j, [[p$j##_type gmock_p$j]]]] +$var impl_inits = [[$if i==0 [[]] $else [[ : $for j, [[p$j(::testing::internal::move(gmock_p$j))]]]]]] +$var inits = [[$if i==0 [[]] $else [[ : $for j, [[p$j(::testing::internal::move(gmock_p$j))]]]]]] +$var params = [[$for j, [[p$j]]]] +$var param_types = [[$if i==0 [[]] $else [[<$for j, [[p$j##_type]]>]]]] +$var param_types_and_names = [[$for j, [[p$j##_type p$j]]]] +$var param_field_decls = [[$for j +[[ + + p$j##_type const p$j;\ +]]]] +$var param_field_decls2 = [[$for j +[[ + + p$j##_type const p$j;\ +]]]] + +#define $macro_name(name$for j [[, p$j]], description)\$template + class $class_name {\ + public:\ + template <typename arg_type>\ + class gmock_Impl : public ::testing::MatcherInterface<\ + GTEST_REFERENCE_TO_CONST_(arg_type)> {\ + public:\ + [[$if i==1 [[explicit ]]]]gmock_Impl($impl_ctor_param_list)\ + $impl_inits {}\ + virtual bool MatchAndExplain(\ + GTEST_REFERENCE_TO_CONST_(arg_type) arg,\ + ::testing::MatchResultListener* result_listener) const;\ + virtual void DescribeTo(::std::ostream* gmock_os) const {\ + *gmock_os << FormatDescription(false);\ + }\ + virtual void DescribeNegationTo(::std::ostream* gmock_os) const {\ + *gmock_os << FormatDescription(true);\ + }\$param_field_decls + private:\ + ::std::string FormatDescription(bool negation) const {\ + ::std::string gmock_description = (description);\ + if (!gmock_description.empty())\ + return gmock_description;\ + return ::testing::internal::FormatMatcherDescription(\ + negation, #name, \ + ::testing::internal::UniversalTersePrintTupleFieldsToStrings(\ + ::testing::tuple<$for j, [[p$j##_type]]>($for j, [[p$j]])));\ + }\ + };\ + template <typename arg_type>\ + operator ::testing::Matcher<arg_type>() const {\ + return ::testing::Matcher<arg_type>(\ + new gmock_Impl<arg_type>($params));\ + }\ + [[$if i==1 [[explicit ]]]]$class_name($ctor_param_list)$inits {\ + }\$param_field_decls2 + private:\ + };\$template + inline $class_name$param_types name($param_types_and_names) {\ + return $class_name$param_types($params);\ + }\$template + template <typename arg_type>\ + bool $class_name$param_types::gmock_Impl<arg_type>::MatchAndExplain(\ + GTEST_REFERENCE_TO_CONST_(arg_type) arg,\ + ::testing::MatchResultListener* result_listener GTEST_ATTRIBUTE_UNUSED_)\ + const +]] + + +#endif // GMOCK_INCLUDE_GMOCK_GMOCK_GENERATED_MATCHERS_H_ diff --git a/googlemock/include/gmock/gmock-generated-nice-strict.h b/googlemock/include/gmock/gmock-generated-nice-strict.h new file mode 100644 index 0000000..91ba1d9 --- /dev/null +++ b/googlemock/include/gmock/gmock-generated-nice-strict.h @@ -0,0 +1,459 @@ +// This file was GENERATED by command: +// pump.py gmock-generated-nice-strict.h.pump +// DO NOT EDIT BY HAND!!! + +// Copyright 2008, Google Inc. +// All rights reserved. +// +// Redistribution and use in source and binary forms, with or without +// modification, are permitted provided that the following conditions are +// met: +// +// * Redistributions of source code must retain the above copyright +// notice, this list of conditions and the following disclaimer. +// * Redistributions in binary form must reproduce the above +// copyright notice, this list of conditions and the following disclaimer +// in the documentation and/or other materials provided with the +// distribution. +// * Neither the name of Google Inc. nor the names of its +// contributors may be used to endorse or promote products derived from +// this software without specific prior written permission. +// +// THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS +// "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT +// LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR +// A PARTICULAR PURPOSE ARE DISCLAIMED.
