How do you approach organizing testing to reduce the number of errors in a project?

To reduce the number of errors in a project, I organize testing as follows:

• Write unit tests for each component to verify their isolated functionality.
• Use integration tests to check interactions between modules.
• Automate tests to run regularly, such as on each commit (CI/CD).
• Include boundary and negative scenario tests to catch edge cases.
• Conduct code reviews to identify potential errors before testing.
• Use static code analysis and linters for early problem detection.

This comprehensive approach helps identify errors early and reduces their occurrence in releases.
