The Advantages and Disadvantages of TDD
Explore the advantages and disadvantages of test-driven development (TDD) to understand how writing tests before code improves software quality while also presenting challenges. This lesson helps you grasp why TDD promotes better design, faster debugging, and maintainability, while acknowledging time investment, learning curves, and test maintenance complexities.
We'll cover the following...
Test-driven development (TDD) is a software development methodology that emphasizes writing tests before writing the actual production code. Essentially, the tests are used as the design process for our code. This approach prompts us to think about the functionality, edge cases, and boundary conditions before we start writing the code.
Advantages of TDD
The following benefits of TDD contribute to its effectiveness:
Improved code quality: By writing tests before the code, TDD encourages developers to think deeply about the expected behavior and design of their code. This helps them to identify potential issues and edge cases early in the development process, leading to higher-quality code.
Faster debugging: Because TDD catches defects early, it reduces the time spent on debugging and fixing ...
