Using the Groovy Script tester

After writing your Groovy script in the editor, click on the Test Groovy Script button on the toolbar. A modal dialog window opens, asking you to pick an issue to run the Groovy script against, as well as a related issue, wherever applicable. 

Selecting an issue

You can select the issue from one of the following options:

• Issue key: start typing an issue key, you will be offered options based on your issue browsing history
• [Select issue]: if you click on [Select Issue], an Issue selector window gets displayed. You can select the issue either from:
  • Recent Issues: Displays issues that you have recently viewed and first 50 issues from your current search or
  • From Filter: Displays issues of your saved searches.

The issue variable used in your script will point to the above-selected issue. 

Selecting a related issue

In post-functions that process an issue’s related issues, after you select an issue (as explained above) in the tester, all issues related to it through the relation selected in Which issue(s) are displayed under Linked issue key. The relatedIssue variable and the deprecated linkedIssue variable used in your script will point to the selected related issue. For example: If the relation is the issues returned by the JQL search, the tester Linked issue key field will show issues that are a result of the JQL search.

In the post-functions that process the parent issue, after you select an issue (as explained above), its parent is displayed under Parent issue key. The parentIssue variable used in your script will point to the parent issue you select.

Testing your Groovy script

After selecting issue(s) against which the script should be tested (as explained above), click on Test. The following information will be displayed. This information can be used for debugging.

1. Message: Success/error message based on the test result.

2. Result type: Data type of the result.
3. Result value: Value of the result.
4. Stack: If an exception was thrown during the execution of the script, a stack trace will be displayed.
5. Logs: Information logged using the log variable.

Example

Debugging your script

If you encounter an error during testing, you will need to debug your script. The Message, Stack and Log information displayed in the script tester result panel aids in debugging the script.

Using the Message and Stack trace

In the above example, after testing the script against an issue that is unassigned:

• Identify the problem, from the Message that displayed a null pointer exception error and the Stack that displayed the line number on which the error occurred.

• Correct the problem, using the safe navigation operator ? that avoids the null pointer exception.

  return (issue.get("assignee")?.getName())

  
  

• Retest the script, as explained above and verify the result in the script test panel. The result value will be null
  

Using the log variable

Using the log variable, you can debug your script, a step further, by adding information into the log. For example, while testing a condition, if the result evaluates to false when you expect it to be true, you might want to know what values are being compared in your condition. In such cases, you can use the log variable to display the value.

Consider the following script,

return (issue.get("assignee")? == "Scharlie")

• Test the script, against an issue assigned to a user Scharlie. The script test would evaluate to false.
  
  

• Identify the problem, using the log variable (as shown below) and check what values are being compared. 

  log.warn("Fetched user is" + " " + issue?.get("assignee")) return (issue?.get("assignee") == "Scharlie")

  Retest the script, as explained above and verify the result in the script test panel. 

The script is comparing a user object to a String value.

• Correct the problem, by fetching the username and then comparing the values

  log.warn("Fetched user is" + " " + issue?.get("assignee")) return (issue?.get("assignee").getName() == "Scharlie")

  
  

• Retest the script, as explained above and verify the result in the script test panel. Now the condition evaluates to true.
  
  
• Remove your logging code, so that log entries don't get written to Jira's logfile each time the post-function is executed.
