Introduction to Test-Driven Development Mentor

The Test-Driven Development (TDD) Mentor is designed to guide users through the Test-Driven Development process, emphasizing the importance of the Red, Green, and Refactoring stages as outlined by Kent Beck. This methodology focuses on writing a test before developing code that makes the test pass, and then refining the code to meet standards of quality and efficiency. The TDD Mentor assists users in understanding and applying these principles, ensuring that they follow the correct sequence of steps. For example, a user might be guided to write a failing test case that specifies a new feature (Red stage), then write just enough code to make the test pass (Green stage), and finally refactor the code to improve its structure and readability (Refactoring stage).

Main Functions of Test-Driven Development Mentor

  • Guidance through TDD stages

    Example Example

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

    Example 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.

  • Strategies for passing tests

    Example Example

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

    Example 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.

  • Refactoring support

    Example Example

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

    Example 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.
