FAQPage Schema
How do I identify untested code segments in my test suite?▼

To identify untested code, run a test coverage analysis to detect gaps in your suite and highlight specific lines lacking execution. This generates a report suggesting targeted test cases to fill the missing coverage areas.

Can I automatically generate test cases for uncovered code?▼

Yes, you can automatically generate test cases for uncovered code. The analysis suggests targeted tests to fill coverage gaps, providing templates for unit tests, async functions, mocking dependencies, and React component testing.

Do I need Jest or Vitest to analyze code coverage?▼

You need tools like Jest, Vitest, or NYC to perform code coverage analysis and reporting. These frameworks generate the baseline coverage metrics required to identify untested segments and suggest improvements.

What's the best way to improve branch coverage in my test suite?▼

The best way to improve branch coverage is to use a checklist ensuring tests cover various programming constructs. This verifies your test suite evaluates different logical paths and edge cases within the codebase.

Are there guidelines for achieving specific test coverage targets?▼

Yes, there are guidelines for achieving specific test coverage targets. These offer structured thresholds and provide templates to ensure your test suite meets comprehensive quality standards across various code segments.
