Claude Code enhanced with automated test execution via PostToolUse hooks

By PulseAugur Editorial · [1 sources] ·

A developer has created a method to automatically run tests after code edits within Claude Code, an AI coding assistant. This is achieved by implementing a PostToolUse hook, which triggers a Python script to execute tests immediately following file modifications. The hook is configured to only run for specific file types and ensures tests are executed quickly to provide rapid feedback to the agent, preventing it from discovering errors much later in the development process. AI

IMPACT Enables more robust and immediate feedback loops for AI coding assistants, potentially improving developer productivity and code quality.

    Make Claude Code run your tests after every edit with a PostToolUse hook

    <p>Telling a coding agent "run the tests after you change something" works most of the time. A hook makes it work every time, and it costs about a dozen lines.</p> <p>Claude Code fires <code>PostToolUse</code> hooks after a tool call finishes. If you match on the file-editing too…
