|
||
| // A class for indicating whether an assertion was successful. When | ||
| // the assertion wasn't successful, the AssertionResult object | ||
| // remembers a non-empty message that describes how it failed. | ||
| // | ||
| // To create an instance of this class, use one of the factory functions | ||
| // (AssertionSuccess() and AssertionFailure()). | ||
| // | ||
| // This class is useful for two purposes: | ||
| // 1. Defining predicate functions to be used with Boolean test assertions | ||
| // EXPECT_TRUE/EXPECT_FALSE and their ASSERT_ counterparts | ||
| // 2. Defining predicate-format functions to be | ||
| // used with predicate assertions (ASSERT_PRED_FORMAT*, etc). | ||
| // | ||
| // For example, if you define IsEven predicate: | ||
| // | ||
| // testing::AssertionResult IsEven(int n) { | ||
| // if ((n % 2) == 0) | ||
| // return testing::AssertionSuccess(); | ||
| // else | ||
| // return testing::AssertionFailure() << n << " is odd"; | ||
| // } | ||
| // | ||
| // Then the failed expectation EXPECT_TRUE(IsEven(Fib(5))) | ||
| // will print the message | ||
| // | ||
| // Value of: IsEven(Fib(5)) | ||
| // Actual: false (5 is odd) | ||
| // Expected: true | ||
| // | ||
| // instead of a more opaque | ||
| // | ||
| // Value of: IsEven(Fib(5)) | ||
| // Actual: false | ||
| // Expected: true | ||
| // | ||
| // in case IsEven is a simple Boolean predicate. | ||
| // | ||
| // If you expect your predicate to be reused and want to support informative | ||
| // messages in EXPECT_FALSE and ASSERT_FALSE (negative assertions show up | ||
| // about half as often as positive ones in our tests), supply messages for | ||
| // both success and failure cases: | ||
| // | ||
| // testing::AssertionResult IsEven(int n) { | ||
| // if ((n % 2) == 0) | ||
| // return testing::AssertionSuccess() << n << " is even"; | ||
| // else | ||
| // return testing::AssertionFailure() << n << " is odd"; | ||
| // } | ||
| // | ||
| // Then a statement EXPECT_FALSE(IsEven(Fib(6))) will print | ||
| // | ||
| // Value of: IsEven(Fib(6)) | ||
| // Actual: true (8 is even) | ||
| // Expected: false | ||
| // | ||
| // NB: Predicates that support negative Boolean assertions have reduced | ||
| // performance in positive ones so be careful not to use them in tests | ||
| // that have lots (tens of thousands) of positive Boolean assertions. | ||
| // | ||
| // To use this class with EXPECT_PRED_FORMAT assertions such as: | ||
| // | ||
| // // Verifies that Foo() returns an even number. | ||
| // EXPECT_PRED_FORMAT1(IsEven, Foo()); | ||
| // | ||
| // you need to define: | ||
| // | ||
| // testing::AssertionResult IsEven(const char* expr, int n) { | ||
| // if ((n % 2) == 0) | ||
| // return testing::AssertionSuccess(); | ||
| // else | ||
| // return testing::AssertionFailure() | ||
| // << "Expected: " << expr << " is even\n Actual: it's " << n; | ||
| // } | ||
| // | ||
| // If Foo() returns 5, you will see the following message: | ||
| // | ||
| // Expected: Foo() is even | ||
| // Actual: it's 5 | ||
| // | ||
