discord9 b3faf22290 fix(tests): make two Windows CI failures deterministic (Nightly CI #8837) (#8840)
* fix(tests): reject overlay directories before opening on all platforms

DatanodeOverlay::load() opened the target before checking is_file(). On
Unix, File::open on a directory succeeds and the loader rejects it with
"must be a regular file". On Windows, File::open on a directory fails up
front with "Access is denied", so the type check was never reached and
the rejects_directories_and_parse_errors test failed 4/4 in Nightly CI
(issue #8837).

Check std::fs::metadata before File::open: metadata succeeds on
directories on both platforms, so the error message is now identical
everywhere and the test assertion holds on Windows too.

* test(datanode): make test_region_error deterministic across platforms

The second phase raced a 100ms mock handle delay against a 200ms
replay_timeout; on busy Windows CI runners the error could land after the
timeout fired, flaking reply.error.is_some() (Nightly CI, issue #8837).
Use a mock handle that returns the error on its first poll with no delay:
the catchup future completes before replay_timeout can ever fire, so the
test no longer depends on wall-clock scheduling.

Sqlness Test

Sqlness manual

Case file

Sqlness has two types of file:

  • .sql: test input, SQL only
  • .result: expected test output, SQL and its results

.result is the output (execution result) file. If you see .result files is changed, it means this test gets a different result and indicates it fails. You should check change logs to solve the problem.

You only need to write test SQL in .sql file, and run the test.

Case organization

The root dir of input cases is tests/cases. It contains several subdirectories stand for different test modes. E.g., standalone/ contains all the tests to run under greptimedb standalone start mode.

Under the first level of subdirectory (e.g. the cases/standalone), you can organize your cases as you like. Sqlness walks through every file recursively and runs them.

Kafka WAL

Sqlness supports Kafka WAL. You can either provide a Kafka cluster or let sqlness to start one for you.

To run test with kafka, you need to pass the option -w kafka. If no other options are provided, sqlness will use conf/kafka-cluster.yml to start a Kafka cluster. This requires docker and docker-compose commands in your environment.

Otherwise, you can additionally pass the your existing kafka environment to sqlness with -k option. E.g.:

cargo sqlness bare -w kafka -k localhost:9092

In this case, sqlness will not start its own kafka cluster and the one you provided instead.

Run the test

Unlike other tests, this harness is in a binary target form. You can run it with:

cargo sqlness bare

It automatically finishes the following procedures: compile GreptimeDB, start it, grab tests and feed it to the server, then collect and compare the results. You only need to check if the .result files are changed. If not, congratulations, the test is passed 🥳!
