Poku offers mini-lessons for different users needs in the Quick Tutorials section.
- Avoiding conflicts in environments with multiple platforms installed.
- Properly running asynchronous tests on the same file.
- Using Poku without installing on Deno and alternatives to JSR.
- Migrating from version 1.x to version 2.x.
Poku is continuously tested to ensure the following expectations for basic usage:
- ~4x faster than Jest (v29.7.0)
- ~4x faster than Vitest (v2.1.3)
- ~2x faster than Mocha (v10.7.3) — even with test file isolation
- You can see how the tests are run and compared in the benchmark directory.
- Comparing Poku and native test runners (discussion).
Poku size ensures cost-saving CI for services that charge for storage and usage.
