| // a const char*. That const char* is the path to a file with the provided name |

| // * zxtest, the gtest workalike subset sometimes used in the Fuchsia build |
| // The default is to use llvm-libc's own gtest workalike framework. |
| // |
| // All the frameworks provide the basic EXPECT_* and ASSERT_* macros that gtest |
| // does. The wrapper headers below define LIBC_NAMESPACE::testing::Test as the |
| // base class for test fixture classes. Each also provides a definition of the |
| // macro LIBC_TEST_HAS_MATCHERS() for use in `#if` conditionals to guard use of |
| // gmock-style matchers, which zxtest does not support. |
