title: Is it possible to uninitialize/reinitialize/delete role in testcafe E2E test?
body: <p>I am using TestCafe for my E2E testing.</p>
  
  <p>Scenario: I am running a test use test runs. For example, first test run executes tests in firefox browser, and next run in chrome (this is just example, I have cases where I need to run e2e tests in different stages as well). I have used a role. When one test run completes, and it is running another test run, still the role cookie persists, and it acts as the user is logged in.</p>
  
  <p>Expected behavior: Roles should be re-initialized for each run.</p>
  
  <p>Is there some way I can clean the cookie, or un-initialize the roles?</p>
