JMWE for Jira Cloud includes a tool for testing Jira expressions; with this tool, an expression can be built and verified before adding it to a condition or validator configuration. The main advantage of this tool is that expressions can be built and debugged quickly, and changes can be made without having to actually trigger a transition and/or look at the JMWE logs to see the result.

The expression tester is available through the JIRA MISC WORKFLOW EXTENSIONS section of Jira App Administration. To access the Jira expression tester:

  1. In Jira, click the Settings icon in the upper right corner of the page and select Apps.

  2. In the left-hand panel, under JIRA MISC WORKFLOW EXTENSIONS, click Nunjucks and Jira expression tester.

  3. Under Type select Jira expression.

Using the Tester

The transition variable will not reflect transition information during testing.

After writing your Jira expressions script in the editor, click Test Jira expression in the upper right corner of the editor. A window will open; from this window, select an issue against which to run the Jira expression. Any issue variable used in your script will point to this issue. 

Test Results

After selecting the issue against which the script should be tested, 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 value: Value of the result.

This information can be used for debugging.
