Testing 
======= 
 
Zstandard CI testing is split up into three sections: 
short, medium, and long tests. 
 
Short Tests 
----------- 
Short tests run on CircleCI for new commits on every branch and pull request. 
They consist of the following tests: 
- Compilation on all supported targets (x86, x86_64, ARM, AArch64, PowerPC, and PowerPC64) 
- Compilation on various versions of gcc, clang, and g++ 
- `tests/playTests.sh` on x86_64, without the tests on long data (CLI tests) 
- Small tests (`tests/legacy.c`, `tests/longmatch.c`) on x64_64 
 
Medium Tests 
------------ 
Medium tests run on every commit and pull request to `dev` branch, on TravisCI. 
They consist of the following tests: 
- The following tests run with UBsan and Asan on x86_64 and x86, as well as with 
  Msan on x86_64 
  - `tests/playTests.sh --test-large-data` 
  - Fuzzer tests: `tests/fuzzer.c`, `tests/zstreamtest.c`, and `tests/decodecorpus.c` 
- `tests/zstreamtest.c` under Tsan (streaming mode, including multithreaded mode) 
- Valgrind Test (`make -C tests valgrindTest`) (testing CLI and fuzzer under valgrind) 
- Fuzzer tests (see above) on ARM, AArch64, PowerPC, and PowerPC64 
 
Long Tests 
---------- 
Long tests run on all commits to `release` branch,
and once a day on the current version of `dev` branch, 
on TravisCI. 
They consist of the following tests: 
- Entire test suite (including fuzzers and some other specialized tests) on: 
  - x86_64 and x86 with UBsan and Asan 
  - x86_64 with Msan 
  - ARM, AArch64, PowerPC, and PowerPC64 
- Streaming mode fuzzer with Tsan (for the `zstdmt` testing) 
- ZlibWrapper tests, including under valgrind 
- Versions test (ensuring `zstd` can decode files from all previous versions) 
- `pzstd` with asan and tsan, as well as in 32-bits mode 
- Testing `zstd` with legacy mode off 
- Entire test suite and make install on macOS
