Scenario: Expected outcome title

Steps within scenario

Given: Sets up initial state

(Optional) And/But: after any Given,When,Then sentence

  1. Feature supersets,
  2. important
  3. slow/fast
  4. w.i.p
  5. weekly,daily,hourly
  6. humanexecuted

Data tables in steps; alternative to multiple ‘And’ steps

Colon at end of a step : Each list item inbetween vertical lines |‘s

Given I have the following tools:

| paste |

| brush |

| water |

Variables inside given,when,then steps surrounded by ’< >‘ marks then a list in a column format with the variable header at the top; vertical lines |’s whole way down.

Regular expression notes

Forward slashes / start the notation of a regular expression within a step definition file in front of a Given,When,Then keyword.

Cucumber ignores the Given…* keywords for its automation tests

Escaping characters are done by backslashing special symbols e.g. \$

Arguments are captured by surrounding them in parenthesis marks “( )”

Inside these parenthesis marks, regular expression notations can be used e.g. ( [0..9]* ) or ( \d+)

(?: … ) : ?: means that it’s a noncapturing expression. e.g. (?:visit|go to)


Just enough regular expressions for cucumber
