One can be able to automate End-to-End tests, Integration tests, Unit tests and it also supports API tests.

Cypress provides 2 Eco-system, one is the TestRunner which needs to be locally installed and helps to setup, start and execute the testcases. Another component of Cypress is the Dashboard service here one can record the tests, maintain the history of the test results and so on.
