2) Difficulty in writing tests before code
3) Time-consuming process
4) Limited flexibility in design

Answer 1

Possible problems of test-first development include lack of clear requirements, difficulty in writing tests before code, time-consuming process, and limited flexibility in design.

Step-by-step explanation:

Test-first development, also known as test-driven development (TDD), has its own set of challenges. Some of the possible problems of test-first development include:

1. Lack of clear requirements: When writing tests before code, it can be difficult to define clear requirements. This can lead to ambiguity and make it harder to ensure that the tests cover all the necessary functionality.
2. Difficulty in writing tests before code: It can be challenging to write tests without having any code in place. This requires a strong understanding of the system and its expected behavior.
3. Time-consuming process: Test-first development can be time-consuming, especially when writing detailed tests for every small aspect of the code.
4. Limited flexibility in design: Writing tests first can sometimes lead to a rigid design that may not easily accommodate changes or new features.
