Copying and pasting scenarios to use different values quickly becomes tedious and repetitive:
Scenario: eat 5 out of 12
Given there are 12 cucumbers
When I eat 5 cucumbers
Then I should have 7 cucumbers
Scenario: eat 5 out of 20
Given there are 20 cucumbers
When I eat 5 cucumbers
Then I should have 15 cucumbers
Scenario outlines allow us to more concisely express these examples through the use of a template with placeholders, using Scenario Outline, Examples with tables and < > delimited parameters:
Scenario Outline: eating
Given there are <start> cucumbers
When I eat <eat> cucumbers
Then I should have <left> cucumbers
Examples:
| start | eat | left |
| 12 | 5 | 7 |
| 20 | 5 | 15 |
The Scenario Outline steps provide a template which is never directly run. A Scenario Outline is run once for each row in the Examples section beneath it (not counting the first row).
The way this works is via placeholders. Placeholders must be contained within < > in the Scenario Outline's steps. For example:
Given <I'm a placeholder and I'm ok>
The placeholders indicate that when the Examples row is run they should be substituted with real values from the Examples table. If a placeholder name is the same as a column title in the Examples table then this is the value that will replace it.
You can also use placeholders in Multiline Step Arguments.
IMPORTANT: Your step definitions will never have to match a placeholder. They will need to match the values that will replace the placeholder
So when running the first row of our example:
Examples:
| start | eat | left |
| 12 | 5 | 7 |
The scenario that is actually run is:
Scenario: controlling order
Given there are 12 cucumbers # <start> replaced with 12
When I eat 5 cucumbers # <eat> replaced with 5
Then I should have 7 cucumbers # <left> replaced with 7
