// 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

// {ASSERT|EXPECT}_TRUE() macro to assert that two objects are

// equal.
|

//
|
|
// 2. The {ASSERT|EXPECT}_??() macros do pointer comparisons on
|
|
// pointers (in particular, C strings). Therefore, if you use it
|
|
// with two C strings, you are testing how their locations in memory
|
|
// are related, not how their content is related. To compare two C
|
|
// strings by content, use {ASSERT|EXPECT}_STR*().
|
|
//
|
|
// 3. {ASSERT|EXPECT}_EQ(expected, actual) is preferred to
