Write the Script of a Gherkin Test Case
A Gherkin test case's consultation page is different because of the structure of its Script page. This page offers a specific text editor with syntax highlighting and verification, without autocompletion.
In Squash TM, a Gherkin test case can be executed manually as a classic test case, or exported for an external automated execution.
Gherkin Test Case Script
The Gherkin script language is defined by the language tag in the first line of the script: #language: < local >. You can change the script's language by replacing < local > by the two letters representing the user's language.
- fr for French
- en for English
- es for Spanish
- de for German
For the script's language to be taken into account, the language tag must be in accordance with the Gherkin specifications and be placed first in the script. The keyword "Feature" must also be translated into the desired language. If the tag is missing or invalid, Squash TM will interpret the script as written in English.
The second line contains the keyword "Feature", followed by the name of the test case.
The scenario must be written with the following syntax:
Scenario followed by the name of the test scenario or Scenario Outline followed by the name of the test scenario with datasets
Given followed by the context in which the test must be done
When followed by the action to be done by the user
Then followed by what is expected as a result of the action
Examples followed by a data table containing the datasets of a scenario plan
You can also add further instructions by using keywords indicating a continuation such as and* or but**.

By clicking on the script's text field, it becomes white and editable. Several buttons appear on top of the script, which enable you to:
Confirm the changes made. You can also save them by using the keyboard shortcut [CTRL]+[ALT]+[S]
Cancel the changes made since the last save and switch back to read-only mode
Insert snippets in the script
Check the script's syntax
If the user does not have the permission to modify the test case, or if one of the milestones linked to the test case has a "locked" status, the script cannot be edited.
Snippets are reusable code templates that you can insert in the script editor via the button to save time during the writing.
In Squash TM, the snippets available are:
- param inserts <> for the notation of parameters
- sc inserts a scenario with the keywords Scenario, Given, When, Then
- scout inserts a scenario with the keywords Scenario outline, Given, When, Then, Examples
- tab4*3, tab4*2, tab3*3, tab3*2 inserts data tables whose number of columns and lines is indicated in their name. A heading row is also added
Check the Script's Syntax
When the text field is in editing mode, the button enables you to check that the Gherkin syntax is correct before confirming the changes.
If the script is invalid, a popup appears with an error message from the Gherkin parser.
On a Gherkin test case's consultation page, the button displays a couple of writing tools:
a glossary of keywords
examples of different test scenarios for different features
The help is displayed on the right of the Gherkin script in the same language as the one defined for the script.
