• Migrating from version 1.x to version 2.x.

Quick Comparisons

Performance

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).

Installation Size

• ~230x lighter than Vitest
• ~130x lighter than Jest
• ~30x lighter than Mocha + Chai

Poku size ensures cost-saving CI for services that charge for storage and usage.
