Components are groups of steps that are shared across multiple tests.
That option works in global scope - when you edit a component you change all related tests at once.
So once you
MAKE COMPONENT out of a group of steps - you can summon them with one action. But when you change something inside that group - it will be changed in all tests where you used that group.
Firstly you need to have a step or few which are repeatable and useful in many tests - so they are a great candidate for component. For example steps to log in.
To create a component go to test view and choose the group of steps which will become your one component. Then click
MAKE COMPONENTon their group name:
You can also add existing component to the test. That can be the new one or existing one:
The other way to structure your test in more easy-going way is to create a group out of steps. That does not need to be component (which has global scope), just a group of steps for that particular test:
Whenever you need, you can
MAKE COMPONENT from a group.
