What was the ratio of API testing to frontend testing in the project?

The ratio of API testing to frontend testing in a project depends on the architecture and requirements, but it often looks approximately like this:

• API testing: 60-70% of the total testing volume. This is because the API is the foundation of business logic and integration, and its stability is critical. Automated API tests allow for quick verification of functionality and regression.

• Frontend testing: 30-40%. Usually includes UI tests, which are more fragile and slower, so they are fewer and focus on key user scenarios.

This distribution helps ensure system reliability, minimizes the time spent on maintaining tests, and maximizes coverage of critical parts of the application.
