Making your code base better will make your code coverage worse
Maintaining a minimum of 80% code coverage can influence code decisions negatively, sometimes prioritizing coverage over code quality and functionality.
MAIN POINTS
- Code coverage targets can lead to prioritizing quantity over quality.
- Developers may write superficial tests to meet coverage goals.
- High coverage does not guarantee code reliability or robustness.
- Focus on meaningful tests rather than arbitrary coverage percentages.
TAKEAWAYS
- Evaluate the quality and relevance of tests over mere coverage statistics.
- Encourage writing comprehensive tests that enhance code reliability.
- Avoid setting rigid coverage targets that may compromise code quality.
- Balance coverage goals with practical, effective testing strategies.
