Most developers now use AI to write tests. Far fewer know how to tell a good AI-generated test from a dangerous one. That gap is what this course closes. You’ll go beyond “prompt it and hope” and build the judgment to generate test suites that genuinely protect your code — across the three most widely used languages in the industry today: JavaScript/TypeScript, Java, and Python.
You’ll work hands-on with four of the most important tools in AI testing:
But tools are only half of it. The heart of this course is critical review. You’ll see how AI can quietly turn an existing bug into a passing test, how a suite with 100% line coverage can assert nothing meaningful, and why deleting a failing test is almost always the wrong move. You’ll learn to apply AI-driven TDD — where the AI writes failing tests from a spec, then writes the code to pass them, making it structurally impossible to encode a bug.
