Suites are great for grouping test cases to run them in parallel.

Why use suites?

Structuring your tests into Suites will speed up test runs management.
Still, you can leave some tests not assigned to any suite and run them separately

Using suites

To access Suites view just go to Project view. You will find Suites option on the left.
Click the menu item and create your Suite - test cases group.
By default there is one suite "All tests", where you will find all tests you created in a project.
You can create your suites from Suites view:
  1. 1.
    Click Create new suite button
  2. 2.
    Add Suite name
  3. 3.
    Choose test cases which you want to include in a suite
  4. 4.
    Choose options for a suite
  5. 5.
    Go back to Suites view
  6. 6.
    Now you can run whole suite (e.g. in parallel in cloud)
