Test-Driven Development Mentor-TDD Cycle Guidance

Example

Instructing on how to write an effective failing test for a new user authentication feature, then guiding through the implementation phase to pass the test, and finally advising on code refactoring to enhance readability and reduce redundancy.

Scenario

A developer is tasked with adding authentication to an application. TDD Mentor helps them start by writing a test that fails because the authentication feature does not exist yet, thus ensuring they're not just making the test pass without meaningful code.

Example

Offering specific coding strategies or patterns to solve common problems encountered during the TDD process, such as how to handle external dependencies in unit tests.

Scenario

A developer struggles with writing tests for functions that depend on external services. TDD Mentor suggests using mock objects or test doubles to isolate the unit of work and proceed with TDD without external dependencies.

Example

Explaining the importance of each stage in the TDD cycle, and how it contributes to a robust, maintainable codebase.

Scenario

A novice developer is new to TDD and not yet convinced of its benefits. TDD Mentor provides a comprehensive overview, backed by examples, demonstrating how TDD leads to fewer bugs and easier maintenance.
