What types of testing would you choose with limited time resources?

When time resources are limited, it is advisable to focus on the most effective types of testing that provide maximum coverage of critical functions:

• Smoke testing: a quick set of tests to verify the main functions of the application.
• Regression testing: checking that new changes haven't broken existing functionality.
• Priority testing: testing the most important and frequently used functions.
• Automated testing: if ready automated tests are available, run them to save time.

Thus, it is better to focus on tests that quickly identify critical errors and ensure the stability of key functions.
