`only-one-when`

One action per scenario.

What it does#

A scenario should test one action. Two When steps usually means two scenarios have been joined together, which makes a failure harder to read. By default an And step following a When counts as another When, because it is another action. If your team writes one action across several And steps, turn countAnd off and only real When keywords are counted.

Turning it on#

Add this to your .gurkencheckrc:

{
  "only-one-when": ["on", {"countAnd": true}]
}

Settings#

Setting	Value	If you leave it out	What it does
`countAnd`	true or false	`true`	Whether an And step following a When counts as another When. Set it to false to count only real When keywords.
