// As of September 2016, we continue to attempt to avoid the use of gmock aka
// googlemock included in the test framework
// (https://github.com/google/googletest) to discourage over-eager use of mocks
// that lead to cumbersome class hierarchies and tests that might end up not
// testing real code in important ways.
#include <gtest/gtest.h> // IWYU pragma: export
// Includes gmock.h and enables the use of gmock matchers in tensorflow tests.
//
// Test including this header can use the macros EXPECT_THAT(...) and
// ASSERT_THAT(...) in combination with gmock matchers.
// Example:
// std::vector<int> vec = Foo();
// EXPECT_THAT(vec, ::testing::ElementsAre(1,2,3));
// EXPECT_THAT(vec, ::testing::UnorderedElementsAre(2,3,1));
//
// For more details on gmock matchers see:
// https://github.com/google/googletest/blob/master/googlemock/docs/CheatSheet.md#matchers
//
// The advantages of using gmock matchers instead of self defined matchers are
// better error messages, more maintainable tests and more test coverage.
