2023-02-07[libc][NFC] Move UnitTest and IntegrationTest to the 'test' directory.Siva Chandra Reddy
This part of the effort to make all test related pieces into the `test` directory. This helps is excluding test related pieces in a straight forward manner if LLVM_INCLUDE_TESTS is OFF. Future patches will also move the MPFR wrapper and testutils into the 'test' directory.
2022-11-02[libc] Improve testing of mem functionsGuillaume Chatelet
This patch extracts the testing logic from `op_tests.cpp` into `memory_check_utils.h` so we can reuse it for mem* function integration tests. This makes testing consistent and thorough. For instance this catches a bug that got unnoticed during submission of D136595 and D135134. Integration test for memcmp was only testing a single size. This also leverages ASAN to make sure that data is not read / written outside permitted boundaries Differential Revision: https://reviews.llvm.org/D136865

2021-12-22[libc] apply formatting to testsMichael Jones
Apply the formatting rules that were applied to the libc/src directory to the libc/test directory, as well as the files in libc/utils that are included by the tests. This does not include automated enforcement. Reviewed By: sivachandra, lntue Differential Revision: https://reviews.llvm.org/D116127
2021-09-10[libc] Check signs instead of values in memcmp unittests.Cheng Wang
The C standard only guarantees the sign of return value. The exact return value is implementation defined. Reviewed By: gchatelet Differential Revision: https://reviews.llvm.org/D109588

2021-01-20[libc][NFC] add "LlvmLibc" as a prefix to all test namesMichael Jones
Summary: Having a consistent prefix makes selecting all of the llvm libc tests easier on any platform that is also using the gtest framework. This also modifies the TEST and TEST_F macros to enforce this change moving forward. Reviewers: sivachandra Subscribers:
