# scenario outlinesΒΆ

On our first description file, zero.feature, all scenarios were similar. This made us repeat most of the text again and again.

Isn’t there a better way to deal with this - when several scenarios are almost equal and only some values change?

Yes, there is! :) You just need to use scenarios outlines.

An example is shown bellow:

```Feature: Compute factorial
In order to play with Lettuce
As beginners
We'll implement factorial

Scenario Outline: Factorials [0-4]
Given I have the number <number>
When I compute its factorial
Then I see the number <result>

Examples:
| number | result |
| 0      | 1      |
| 1      | 1      |
| 2      | 2      |
| 3      | 6      |
| 4      | 24     |```

This way, you will only need to provide the values that really change, reducing “copy & paste” work and making your tests more clear.

Note

If you overwrite zero.feature using the example above, and goto step [e], you’ll see your description expanding to the five previous scenarious:
