It will not 376$$ // show up in the generated code. 377 378 379// The MATCHER* family of macros can be used in a namespace scope to 380// define custom matchers easily. 381// 382// Basic Usage 383// =========== 384// 385// The syntax 386// 387// MATCHER(name, description_string) { statements; } 388// 389// defines a matcher with the given name that executes the statements, 390// which must return a bool to indicate if the match succeeds. Inside 391// the statements, you can refer to the value being matched by 'arg', 392// and refer to its type by 'arg_type'. 393// 394// The description string documents what the matcher does, and is used 395// to generate the failure message when the match fails. Since a 396// MATCHER() is usually defined in a header file shared by multiple 397// C++ source files, we require the description to be a C-string 398// literal to avoid possible side effects. It can be empty, in which 399// case we'll use the sequence of words in the matcher name as the 400// description. 401// 402// For example: 403// 404// MATCHER(IsEven, "") { return (arg % 2) == 0; } 405// 406// allows you to write 407// 408// // Expects mock_foo.Bar(n) to be called where n is even. 409// EXPECT_CALL(mock_foo, Bar(IsEven())); 410// 411// or, 412// 413// // Verifies that the value of some_expression is even. 414// EXPECT_THAT(some_expression, IsEven()); 415// 416// If the above assertion fails, it will print something like: 417// 418// Value of: some_expression 419// Expected: is even 420// Actual: 7 421// 422// where the description "is even" is automatically calculated from the 423// matcher name IsEven. 424// 425// Argument Type 426// ============= 427// 428// Note that the type of the value being matched (arg_type) is 429// determined by the context in which you use the matcher and is 430// supplied to you by the compiler, so you don't need to worry about 431// declaring it (nor can you). This allows the matcher to be 432// polymorphic. For example, IsEven() can be used to match any type 433// where the value of "(arg % 2) == 0" can be implicitly converted to 434// a bool. In the "Bar(IsEven())" example above, if method Bar() 435// takes an int, 'arg_type' will be int; if it takes an unsigned long, 436// 'arg_type' will be unsigned long; and so on. 437// 438// Parameterizing Matchers 439// ======================= 440// 441// Sometimes you'll want to parameterize the matcher. For that you 442// can use another macro: 443// 444// MATCHER_P(name, param_name, description_string) { statements; } 445// 446// For example: 447// 448// MATCHER_P(HasAbsoluteValue, value, "") { return abs(arg) == value; } 449// 450// will allow you to write: 451// 452// EXPECT_THAT(Blah("a"), HasAbsoluteValue(n)); 453// 454// which may lead to this message (assuming n is 10): 455// 456// Value of: Blah("a") 457// Expected: has absolute value 10 458// Actual: -9 459// 460// Note that both the matcher description and its parameter are 461// printed, making the message human-friendly. 462// 463// In the matcher definition body, you can write 'foo_type' to 464// reference the type of a parameter named 'foo'. For example, in the 465// body of MATCHER_P(HasAbsoluteValue, value) above, you can write 466// 'value_type' to refer to the type of 'value'. 467// 468// We also provide MATCHER_P2, MATCHER_P3, ..., up to MATCHER_P$n to 469// support multi-parameter matchers. 470// 471// Describing Parameterized Matchers 472// ================================= 473// 474// The last argument to MATCHER*() is a string-typed expression. The 475// expression can reference all of the matcher's parameters and a 476// special bool-typed variable named 'negation'. When 'negation' is 477// false, the expression should evaluate to the matcher's description; 478// otherwise it should evaluate to the description of the negation of 479// the matcher. For example, 480// 481// using testing::PrintToString; 482// 483// MATCHER_P2(InClosedRange, low, hi, 484// string(negation ? "is not" : "is") + " in range [" + 485// PrintToString(low) + ", " + PrintToString(hi) + "]") { 486// return low <= arg && arg <= hi; 487// } 488// ... 489// EXPECT_THAT(3, InClosedRange(4, 6)); 490// EXPECT_THAT(3, Not(InClosedRange(2, 4))); 491// 492// would generate two failures that contain the text: 493// 494// Expected: is in range [4, 6] 495// ... 496// Expected: is not in range [2, 4] 497// 498// If you specify "" as the description, the failure message will 499// contain the sequence of words in the matcher name followed by the 500// parameter values printed as a tuple. For example, 501// 502// MATCHER_P2(InClosedRange, low, hi, "") { ... } 503// ... 504// EXPECT_THAT(3, InClosedRange(4, 6)); 505// EXPECT_THAT(3, Not(InClosedRange(2, 4))); 506// 507// would generate two failures that contain the text: 508// 509// Expected: in closed range (4, 6) 510// ... 511// Expected: not (in closed range (2, 4)) 512// 513// Types of Matcher Parameters 514// =========================== 515// 516// For the purpose of typing, you can view 517// 518// MATCHER_Pk(Foo, p1, ..., pk, description_string) { ... } 519// 520// as shorthand for 521// 522// template <typename p1_type, ..., typename pk_type> 523// FooMatcherPk<p1_type, ..., pk_type> 524// Foo(p1_type p1, ..., pk_type pk) { ... } 525// 526// When you write Foo(v1, ..., vk), the compiler infers the types of 527// the parameters v1, ..., and vk for you. If you are not happy with 528// the result of the type inference, you can specify the types by 529// explicitly instantiating the template, as in Foo<long, bool>(5, 530// false). As said earlier, you don't get to (or need to) specify 531// 'arg_type' as that's determined by the context in which the matcher 532// is used. You can assign the result of expression Foo(p1, ..., pk) 533// to a variable of type FooMatcherPk<p1_type, ..., pk_type>. This 534// can be useful when composing matchers. 535// 536// While you can instantiate a matcher template with reference types, 537// passing the parameters by pointer usually makes your code more 538// readable. If, however, you still want to pass a parameter by 539// reference, be aware that in the failure message generated by the 540// matcher you will see the value of the referenced object but not its 541// address. 542// 543// Explaining Match Results 544// ======================== 545// 546// Sometimes the matcher description alone isn't enough to explain why 547// the match has failed or succeeded. For example, when expecting a 548// long string, it can be very helpful to also print the diff between 549// the expected string and the actual one. To achieve that, you can 550// optionally stream additional information to a special variable 551// named result_listener, whose type is a pointer to class 552// MatchResultListener: 553// 554// MATCHER_P(EqualsLongString, str, "") { 555// if (arg == str) return true; 556// 557// *result_listener << "the difference: " 558/// << DiffStrings(str, arg); 559// return false; 560// } 561// 562// Overloading Matchers 563// ==================== 564// 565// You can overload matchers with different numbers of parameters: 566// 567// MATCHER_P(Blah, a, description_string1) { ... } 568// MATCHER_P2(Blah, a, b, description_string2) { ... } 569// 570// Caveats 571// ======= 572// 573// When defining a new matcher, you should also consider implementing 574// MatcherInterface or using MakePolymorphicMatcher(). These 575// approaches require more work than the MATCHER* macros, but also 576// give you more control on the types of the value being matched and 577// the matcher parameters, which may leads to better compiler error 578// messages when the matcher is used wrong. They also allow 579// overloading matchers based on parameter types (as opposed to just 580// based on the number of parameters). 581// 582// MATCHER*() can only be used in a namespace scope. The reason is 583// that C++ doesn't yet allow function-local types to be used to 584// instantiate templates. The up-coming C++0x standard will fix this. 585// Once that's done, we'll consider supporting using MATCHER*() inside 586// a function. 587// 588// More Information 589// ================ 590// 591// To learn more about using these macros, please search for 'MATCHER' 592// on http://code.google.com/p/googlemock/wiki/CookBook. 593 594$range i 0..n 595$for i 596 597[[ 598$var macro_name = [[$if i==0 [[MATCHER]] $elif i==1 [[MATCHER_P]] 599 $else [[MATCHER_P$i]]]] 600$var class_name = [[name##Matcher[[$if i==0 [[]] $elif i==1 [[P]] 601 $else [[P$i]]]]]] 602$range j 0..i-1 603$var template = [[$if i==0 [[]] $else [[ 604 605 template <$for j, [[typename p$j##_type]]>\ 606]]]] 607$var ctor_param_list = [[$for j, [[p$j##_type gmock_p$j]]]] 608$var impl_ctor_param_list = [[$for j, [[p$j##_type gmock_p$j]]]] 609$var impl_inits = [[$if i==0 [[]] $else [[ : $for j, [[p$j(gmock_p$j)]]]]]] 610$var inits = [[$if i==0 [[]] $else [[ : $for j, [[p$j(gmock_p$j)]]]]]] 611$var params = [[$for j, [[p$j]]]] 612$var param_types = [[$if i==0 [[]] $else [[<$for j, [[p$j##_type]]>]]]] 613$var param_types_and_names = [[$for j, [[p$j##_type p$j]]]] 614$var param_field_decls = [[$for j 615[[ 616 617 p$j##_type p$j;\ 618]]]] 619$var param_field_decls2 = [[$for j 620[[ 621 622 p$j##_type p$j;\ 623]]]] 624 625#define $macro_name(name$for j [[, p$j]], description)\$template 626 class $class_name {\ 627 public:\ 628 template <typename arg_type>\ 629 class gmock_Impl : public ::testing::MatcherInterface<arg_type> {\ 630 public:\ 631 [[$if i==1 [[explicit ]]]]gmock_Impl($impl_ctor_param_list)\ 632 $impl_inits {}\ 633 virtual bool MatchAndExplain(\ 634 arg_type arg, ::testing::MatchResultListener* result_listener) const;\ 635 virtual void DescribeTo(::std::ostream* gmock_os) const {\ 636 *gmock_os << FormatDescription(false);\ 637 }\ 638 virtual void DescribeNegationTo(::std::ostream* gmock_os) const {\ 639 *gmock_os << FormatDescription(true);\ 640 }\$param_field_decls 641 private:\ 642 ::testing::internal::string FormatDescription(bool negation) const {\ 643 const ::testing::internal::string gmock_description = (description);\ 644 if (!gmock_description.empty())\ 645 return gmock_description;\ 646 return ::testing::internal::FormatMatcherDescription(\ 647 negation, #name, \ 648 ::testing::internal::UniversalTersePrintTupleFieldsToStrings(\ 649 ::std::tr1::tuple<$for j, [[p$j##_type]]>($for j, [[p$j]])));\ 650 }\ 651 GTEST_DISALLOW_ASSIGN_(gmock_Impl);\ 652 };\ 653 template <typename arg_type>\ 654 operator ::testing::Matcher<arg_type>() const {\ 655 return ::testing::Matcher<arg_type>(\ 656 new gmock_Impl<arg_type>($params));\ 657 }\ 658 $class_name($ctor_param_list)$inits {\ 659 }\$param_field_decls2 660 private:\ 661 GTEST_DISALLOW_ASSIGN_($class_name);\ 662 };\$template 663 inline $class_name$param_types name($param_types_and_names) {\ 664 return $class_name$param_types($params);\ 665 }\$template 666 template <typename arg_type>\ 667 bool $class_name$param_types::gmock_Impl<arg_type>::MatchAndExplain(\ 668 arg_type arg, \ 669 ::testing::MatchResultListener* result_listener GTEST_ATTRIBUTE_UNUSED_)\ 670 const 671]] 672 673 674#endif // GMOCK_INCLUDE_GMOCK_GMOCK_GENERATED_MATCHERS_H_ 675
