# Test Optimization Impact On Overall Code Coverage

TIA offers the advantage of skipping irrelevant tests for each build and release. Consequently, this selective approach may result in lower overall code coverage. This can be a concern if quality gates within an organization rely on code coverage metrics and require a specific threshold for validation.

Similarly, other systems that depend on full test execution, such as SonarCube, may be affected by TIA's selective test runs. It's essential to recognize this potential impact and communicate it proactively with all relevant stakeholders.

In cases where all tests must run for specific reasons, perhaps due to a critical and sensitive code change necessitating a comprehensive system test, you have the option to temporarily disable TIA, or to choose a full run policy for the next build to ensure all tests are executed without skipping any. This allows you to meet the requirements of sensitive code changes while maintaining comprehensive coverage.

Remember that balancing the advantages of TIA's efficiency with the need for comprehensive testing is crucial. Effective communication with stakeholders is key to managing expectations and ensuring quality throughout the development process.
