python-doctest-patterns

You can test Python docstring examples in CI by configuring pytest with the --doctest-modules flag to automatically discover, execute, and validate embedded examples across source files and markdown documents, catching documentation drift early.

Best practices for doctests with exceptions and async functions involve using specific directives and patterns to manage complex outputs, ensuring examples remain correct, illustrative, and synchronized with actual code signatures during validation.

Python doctests fail with unpredictable values because they require exact output matching. You need to apply specific directives and patterns to handle complex outputs, ensuring documented examples remain correct without restricting formatting flexibility.

Yes, you can use pytest to run doctests across both Python source files and README markdown documents. Configuring pytest with --doctest-modules validates all embedded examples to ensure they stay up-to-date and synchronized with code signatures.

The most reliable way to maintain accurate SDK documentation examples is integrating doctest validation into development and CI pipelines. This ensures all public functions and classes have working examples that execute automatically, catching drifts early.

You do not need external testing dependencies to validate documented examples in Python docstrings. You can configure pytest with --doctest-modules to natively discover and run doctests in source files and markdown documents without extra packages.
