Qodo

Qodo (formerly CodiumAI) generates meaningful tests for your code directly inside your IDE — not boilerplate unit tests, but tests that catch actual edge cases and logic errors based on understanding what the code is supposed to do. Paste a function, and Qodo analyzes the intent, generates test cases covering the happy path, edge cases, and failure modes, and explains why each test matters. It works in VS Code and JetBrains, supports most major languages, and integrates with standard test frameworks. Engineering teams use it to dramatically increase test coverage on new code and as a code review aid — the generated tests often reveal bugs the original developer missed.
