What main parameters do you evaluate to measure the effectiveness and quality of testing?

The following parameters are usually used to assess the effectiveness and quality of testing:

• Test coverage — the percentage of code or functionality that is tested.
• Number of defects found — how many bugs were identified during the testing period.
• Quality of found defects — how serious and critical the discovered errors are.
• Test execution time — how quickly the testing is completed.
• Automation percentage — the proportion of tests performed automatically.
• Successful test percentage — how many tests passed without errors.
• Time to fix defects — how quickly bugs are fixed after being found.

These parameters help understand how comprehensively and effectively the product is covered by tests, and how quickly the team responds to issues.
