Your Test Suite Is Your API for Agents

Short summary

Well-written test suites are the best interface for AI agents because they are simultaneously executable, intentional, and current—unlike documentation which drifts. Test names serve as specifications, assertions serve as contracts, and test data documents edge cases. Teams with high-quality, scenario-named tests can let agents self-serve through read-test-modify-test loops without constant human guidance.

• •Test suites are the ideal AI agent interface: executable, intentional, and always current
• •Test naming quality directly determines how well agents can understand and modify systems
• •Low-quality tests force human-in-the-loop; high-quality tests enable autonomous agent workflows
