test failed issue

[qujihan]

hi, @erikgrinaker , thanks for yor great project!

When I run cargo test ---test tests it says invalid input: table test already exists, I think I can fix it by deleting the datadir, but I'm not sure where the datadir is set to.

Can you tell me how I should look at datadir how to view it?

Each test runs in its own isolated data directory, which is deleted when the test exits.

It sounds like there may be stray toyDB processes still running for some reason, possibly from old tests. Try looking for any processes with e.g. ps aux | grep toydb and killing them.

The test harness setup/teardown code is in https://github.com/erikgrinaker/toydb/blob/master/tests/testcluster.rs.
