Testing done:
A PR must be marked "[WIP]", if no test result is provided. A WIP PR won't be reviewed, nor merged.
The requester can determine a sufficient test, e.g. build for a cosmetic change, E2E test in a predeployed setup, etc.
For new features, new tests should be done, in addition to regression tests.
If jtest is used to trigger precheckin tests, paste the result after jtest completes and remove [WIP] in the PR subject.
The review cycle will start, only after "[WIP]" is removed from the PR subject.
