 | |
| // 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.
 | |

 | |
| //
 | |
| // Please also note that generator expressions (including parameters to the

 | |
| // This allows the user on one hand, to adjust generator parameters in order

| // reflection API before RUN_ALL_TESTS() is executed.

| // for more examples.
 | |
| //
 | |

| // A parameterized test fixture must be derived from testing::Test and from

 | |
| class BaseTest : public ::testing::Test {

|   // fixture here.
