Test Generator Skill

Generate comprehensive test cases for the specified function or module.

Test Categories to Cover

1. Happy path: Normal expected inputs produce expected outputs
2. Edge cases: Empty inputs, maximum values, boundary conditions
3. Error cases: Invalid inputs, missing parameters, type mismatches
4. Integration: Interaction with dependencies (mock where needed)

Output Format

Generate a complete test file:

describe("[FunctionName]", () => {
  // Happy path tests
  it("should [expected behavior] when [condition]", () => {
    // Arrange, Act, Assert
  });

  // Edge case tests
  it("should handle [edge case]", () => {
    // ...
  });

  // Error case tests
  it("should throw when [error condition]", () => {
    // ...
  });
});

Guidelines

• Each test should test ONE behavior
• Use descriptive test names that explain the scenario
• Mock external dependencies, don't mock the function under test
• Minimum 5 tests per function
