observability-testing

Test that your code produces correct logs — not just that it runs.

Logs are your only window into production behavior. If critical paths don't log correctly, you're flying blind during incidents. This skill teaches you to verify structured log output as part of your test suite.

When to use: Testing error logging with context, audit trails, monitoring integration, log level policy enforcement, any code where observability matters.
