How do you distribute the share of manual and automated testing in a project?

The distribution of manual and automated testing depends on the project's specifics, its stage, and quality requirements. Usually, automation is suitable for repetitive, regression tests and critical scenario checks, which helps save time and reduce human error. Manual testing is effective for exploratory testing, UX/UI checks, and tests requiring flexibility and intuition.

An approximate ratio might be:

• In early development stages — more manual testing for quick problem detection.
• As the product stabilizes — increased automation for regression coverage.

It is important to consider:

• Automation requires time for scripting and maintenance.
• Not all tests are suitable for automation (e.g., visual checks).

Thus, the balance is chosen based on goals, resources, and project specifics.
