discord9 27090496d1 test(flow): stabilize FLUSH_FLOW assertions after async source-table mirrors (#9230)
* test(flow): wait for async source-table mirrors before FLUSH_FLOW

Streaming flows execute inline in the flownode insert handler since
#8976, and source-table inserts are mirrored from the frontend as
detached tasks. Tests that INSERT then ADMIN FLUSH_FLOW then SELECT
intermittently miss rows on slow CI runners because the flush no longer
implies the mirror reached the flownode (flow_no_aggr lost row 'l',
flow_advance_ttl lost row '23' after the post-restart reinsert).

Add SQLNESS SLEEP 3s between those mirror inserts and the flush, the
established pattern in the flow suite, so the assertions are stable.

* test(flow): also guard first-section flushes in flow_advance_ttl

Local reproduction without sleeps failed in a window the previous
commit did not cover: the first INSERT (20,20,22) of each section is
followed immediately by ADMIN FLUSH_FLOW, and the distributed run
observed an empty sink on that SELECT (~1 in 8 iterations). Add the
same SLEEP 3s guard before those two flushes.

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 🥳!
