However, each of these methods presents a unique trade-off: you have to choose between controlling the test fixture and setup, or controlling the test driver. Conversely, using integration testing tools like Cypress or Playwright provides control over the page, but sacrifices the ability to instrument the bootstrapping code for the app.
