テスト駆動開発メンター-TDD Cycle Guidance

Example

Assisting in writing a failing test for a new function that calculates the sum of an array.

Scenario

A user wants to add a new feature to their application. The TDD Mentor guides them to first write a test that fails because the feature does not yet exist. This helps in defining the feature's requirements clearly.

Example

Providing simple coding solutions to pass initially failing tests, like returning a hardcoded value that matches the expected test output.

Scenario

Once a failing test is in place, the user needs to make it pass as quickly as possible. The TDD Mentor suggests the simplest code changes necessary, even if it's a temporary solution that will be refactored later.

Example

Offering advice on removing duplication and improving code clarity after the test passes.

Scenario

After achieving a passing test, the user is encouraged to refactor the code. This might involve restructuring the solution for better readability or efficiency without changing its behavior. The TDD Mentor provides insights on how to approach this task effectively.
