API testing tools

Coding tools assist with tasks such as generation, explanation, review and debugging. Match the product to your language, repository and review process.

Compare repository access, context limits, supported languages and tool permissions. Check whether the assistant can read relevant files and run your existing checks.

Review the diff, run tests and inspect error handling and dependency changes. Generated code should meet the same review standard as a human contribution.

Choose a small reproducible bug with an existing failing check. Measure whether the tool fixes the cause, preserves behavior and produces a reviewable change.
