This addition reads command line input to run specific single tests within a larger call to run all the tests for a particular function. When the user adds a second argument to the command line, the code skips all the tests that don't match the user's specified binary. If the user doesn't specify a test correctly and/or no tests are run, a failure message prints. Reviewed By: sivachandra, aeubanks Differential Revision: https://reviews.llvm.org/D105843
The LLVM libc unit test framework
This directory contains a lightweight implementation of a gtest like unit test framework for LLVM libc.
Why not gtest?
While gtest is great, featureful and time tested, it uses the C and C++ standard libraries. Hence, using it to test LLVM libc (which is also an implementation of the C standard libraries) causes various kinds of mixup/conflict problems.
How is it different from gtest?
LLVM libc's unit test framework is much less featureful as compared to gtest. But, what is available strives to be exactly like gtest.
Will it be made as featureful as gtest in future?
It is not clear if LLVM libc needs/will need every feature of gtest. We only intend to extend it on an as needed basis. Hence, it might never be as featureful as gtest.
