What types of testing do you know besides unit tests?

In addition to unit tests, the following types of testing exist in frontend development:

• Integration tests — check the interaction between multiple components or modules.
• E2E (end-to-end) tests — simulate user behavior by testing the entire application through the UI (for example, using Cypress, Selenium).
• Snapshot tests — record the visual or structural state of a component and verify that it has not changed unexpectedly.
• Performance tests — measure the load time and responsiveness of the interface.
• Accessibility (a11y) tests — check how accessible the interface is for users with disabilities.
• Regression tests — aimed at identifying errors that appeared after code changes.

Each of these testing types helps improve the quality and stability of the frontend application.
