FAQ

Questions Test Assertion Density Calculator owners ask.

  • 01

    How does the capability identify empty tests?

    The capability uses deterministic regex to find test blocks (it, test, dscribe) and checks if they contain any assertion keywords like expect, assert, or should.

  • 02

    What is a good assertion density?

    A density of 2.0 or higher is considered robust, while anything below 0.5 indicates a high probability of ineffective test structures.

  • 03

    Can I use this with Vitest or Jest?

    Yes, as long as your test files use standard keywords like it, test, expect, or assert, the capability will accurately calculate metrics.
