When creating test for different features of your product you may need to start the test with a login to allow user access to some of the more important features.
So you do not need to logout and login before creating each of your individual tests you need to create a reusable login test. You can then choose to save this login test as the default login under your test settings.
To do this just go to the Test Settings > Defaults page and then click the
Default Login Test dropdown. This will bring up all your tests, but you can scroll through or type to search for this reusable login test.
Changing your timezone will make it so that under test details you will see when it was ran in the Timezone of your choice.
To change it, click on
Current Timezone and select the one you wish
You can specify how many tests can run at the same time. Default and the maximum is 10, but you can change it if you wish.
