Your team has achieved 80% code coverage, but you're encountering difficulties in increasing it further. What strategies would you employ to overcome this challenge?
- Conduct code reviews with a focus on test coverage and encourage peer collaboration to identify testing gaps.
- Identify areas of the code that are difficult to test, such as external dependencies or tightly coupled components, and refactor them for better testability.
- Implement mutation testing to identify gaps in the existing test suite and improve test effectiveness.
- Invest in training and workshops for team members to enhance their understanding of testing principles and best practices.
Refactoring code for better testability can make it easier to write comprehensive tests, while mutation testing can help uncover weaknesses in the existing test suite, leading to improvements in overall coverage. Training and workshops can also empower team members to write better tests and understand the importance of thorough testing practices.
