| // Value-parameterized tests allow you to test your code with different |
| // parameters without writing multiple copies of the same test. |
| // |
| // Here is how you use value-parameterized tests: |
| |
| #if 0 |
| |
| // To write value-parameterized tests, first you should define a fixture |
| // class. It is usually derived from testing::TestWithParam<T> (see below for |
| // another inheritance scheme that's sometimes useful in more complicated |
| // class hierarchies), where the type of your parameter values. |
| // TestWithParam<T> is itself derived from testing::Test. T can be any |
| // copyable type. If it's a raw pointer, you are responsible for managing the |
| // lifespan of the pointed values. |
| |
| class FooTest : public ::testing::TestWithParam<const char*> { |
| // You can implement all the usual class fixture members here. |
| }; |
| |
| // Then, use the TEST_P macro to define as many parameterized tests |
| // for this fixture as you want. The _P suffix is for "parameterized" |
| // or "pattern", whichever you prefer to think. |
| |
| TEST_P(FooTest, DoesBlah) { |
| // Inside a test, access the test parameter with the GetParam() method |
| // of the TestWithParam<T> class: |
| EXPECT_TRUE(foo.Blah(GetParam())); |
| ... |
| } |
| |
| TEST_P(FooTest, HasBlahBlah) { |
| ... |
| } |
| |
| // Finally, you can use INSTANTIATE_TEST_SUITE_P to instantiate the test |
| // case with any set of parameters you want. Google Test defines a number |
| // of functions for generating test parameters. They return what we call |
| // (surprise!) parameter generators. Here is a summary of them, which |
| // are all in the testing namespace: |
| // |
| // |
| // Range(begin, end [, step]) - Yields values {begin, begin+step, |
| // begin+step+step, ...}. The values do not |
| // include end. step defaults to 1. |
| // Values(v1, v2, ..., vN) - Yields values {v1, v2, ..., vN}. |
| // ValuesIn(container) - Yields values from a C-style array, an STL |
| // ValuesIn(begin,end) container, or an iterator range [begin, end). |
| // Bool() - Yields sequence {false, true}. |
| // Combine(g1, g2, ..., gN) - Yields all combinations (the Cartesian product |
| // for the math savvy) of the values generated |
| // by the N generators. |
| // |
| // For more details, see comments at the definitions of these functions below |
| // in this file. |
| // |
| // The following statement will instantiate tests from the FooTest test suite |
| // each with parameter values "meeny", "miny", and "moe". |
| |
| INSTANTIATE_TEST_SUITE_P(InstantiationName, |
| FooTest, |
| Values("meeny", "miny", "moe")); |
| |
| // To distinguish different instances of the pattern, (yes, you |
| // can instantiate it more than once) the first argument to the |
| // INSTANTIATE_TEST_SUITE_P macro is a prefix that will be added to the |
| // actual test suite name. Remember to pick unique prefixes for different |
| // instantiations. The tests from the instantiation above will have |
| // these names: |
| // |
| // * InstantiationName/FooTest.DoesBlah/0 for "meeny" |
| // * InstantiationName/FooTest.DoesBlah/1 for "miny" |
| // * InstantiationName/FooTest.DoesBlah/2 for "moe" |
| // * InstantiationName/FooTest.HasBlahBlah/0 for "meeny" |
| // * InstantiationName/FooTest.HasBlahBlah/1 for "miny" |
| // * InstantiationName/FooTest.HasBlahBlah/2 for "moe" |
| // |
| // You can use these names in --gtest_filter. |
| // |
| // This statement will instantiate all tests from FooTest again, each |
| // with parameter values "cat" and "dog": |
| |
| const char* pets[] = {"cat", "dog"}; |
| INSTANTIATE_TEST_SUITE_P(AnotherInstantiationName, FooTest, ValuesIn(pets)); |
| |
| // The tests from the instantiation above will have these names: |
| // |
| // * AnotherInstantiationName/FooTest.DoesBlah/0 for "cat" |
| // * AnotherInstantiationName/FooTest.DoesBlah/1 for "dog" |
| // * AnotherInstantiationName/FooTest.HasBlahBlah/0 for "cat" |
| // * AnotherInstantiationName/FooTest.HasBlahBlah/1 for "dog" |
| // |
| // Please note that INSTANTIATE_TEST_SUITE_P will instantiate all tests |
| // in the given test suite, whether their definitions come before or |
| // AFTER the INSTANTIATE_TEST_SUITE_P statement. |
| // |
| // Please also note that generator expressions (including parameters to the |
| // generators) are evaluated in InitGoogleTest(), after main() has started. |
| // This allows the user on one hand, to adjust generator parameters in order |
| // to dynamically determine a set of tests to run and on the other hand, |
| // give the user a chance to inspect the generated tests with Google Test |
| // reflection API before RUN_ALL_TESTS() is executed. |
| // |
| // You can see samples/sample7_unittest.cc and samples/sample8_unittest.cc |
| // for more examples. |
| // |
| // In the future, we plan to publish the API for defining new parameter |
| // generators. But for now this interface remains part of the internal |
| // implementation and is subject to change. |
| // |
| // |
| // A parameterized test fixture must be derived from testing::Test and from |
| // testing::WithParamInterface<T>, where T is the type of the parameter |
| // values. Inheriting from TestWithParam<T> satisfies that requirement because |
| // TestWithParam<T> inherits from both Test and WithParamInterface. In more |
| // complicated hierarchies, however, it is occasionally useful to inherit |
| // separately from Test and WithParamInterface. For example: |
| |
| class BaseTest : public ::testing::Test { |
| // You can inherit all the usual members for a non-parameterized test |
| // fixture here. |
| }; |
| |
| class DerivedTest : public BaseTest, public ::testing::WithParamInterface<int> { |
| // The usual test fixture members go here too. |
| }; |
| |
| TEST_F(BaseTest, HasFoo) { |
| // This is an ordinary non-parameterized test. |
| } |
| |
| TEST_P(DerivedTest, DoesBlah) { |
| // GetParam works just the same here as if you inherit from TestWithParam. |
| EXPECT_TRUE(foo.Blah(GetParam())); |
