test: Example integration test based on RocksDB gtest infrastructure #172

Closed metaspace closed 2 years ago

metaspace commented 2 years ago

This patch adds a simple integration test based on RocksDB gtest infrastructure. To be functional, the patch requires changes in rocksdb. The patch for rocksdb is currenlty on top of the 6.29.3 branch and can be found here.

Adding a small Readme or a Guide on how to add more tests or run the tests, will help a lot.

I'll update the ZenFS docs with instructions on how to execute and pointers to gtest docs.

Now that I think of it, I think that it would be better if the test suite create the ZenFS filesystem in SetUp() rather than relying on it being present on the device. Will fix that.

Added a github action to run the tests. If they complete without error they produce a coverage report that can be downloaded as a workflow artifact. See this link bottom of page.

I had to move come code from the zenfs utility to the library for the tests to be able to mkfs and mount without duplicated code. It's a lot of changes, but I tried to split it into a bunch of patches that can be reviewed one by one.

For commit c5f4e30: .github/workflows/mtr-test.yaml would also need to bump percona-server to Percona-Server-8.0.28-19

Bumped percona server to 8.0.28-19.

Seems github is broken. I will close this PR and open a new one.
