You can turn Markdown into executable tests by authoring specifications with shell blocks, inline assertions, and check tables, then running them with an executable spec runner to validate outputs automatically.
An executable specification blends documentation with verifiable tests, allowing shell commands, inline assertions, and check tables written directly in Markdown to be executed and validated against implementation behavior.
You can run Alloy models for design validation by embedding Alloy fragments directly within Markdown specifications, allowing the executable spec runner to validate both design models and implementation checks in sync.
Yes, you can validate CLI workflows and API specs using check tables and shell adapters within Markdown, ensuring that documentation and tests remain synchronized and verifiable across implementation cycles.
No specific adapter is required to start, as the executable spec runner supports a pluggable adapter ecosystem with shell adapters, allowing you to execute shell blocks and inline assertions with minimal setup.
You maintain traceability by using frontmatter-driven workflows and traceability integration within the executable spec runner, linking Markdown checks directly to implementation and design review outputs.
