What methods can be used to improve the performance of UI autotests?

To improve the performance of UI automated tests, the following approaches can be used:

• Parallel test execution — run multiple tests simultaneously if the infrastructure supports it.
• Minimize wait times — reduce timeouts and use waits only where truly necessary.
• Use stable locators — so tests do not fail due to UI changes, reducing the number of reruns.
• Optimize test data — use pre-prepared data or mock services to avoid waiting for real server responses.
• Avoid unnecessary screen transitions — test only necessary scenarios without repeating the same actions.
• Cache application state — if possible, to avoid reconfigurations before each test.
• Use headless mode or accelerated emulators — for faster test execution.

Example: in Xcode, you can configure parallel UI test execution through a testing scheme, which significantly reduces the overall runtime.
