On this page
There are two ways to test your expressions, the Expression parser test page and the built-in expression preview in the expression editor provided in each workflow function.
The goal is always the same - preview the outcome of an expression. The results can vary from calculated dates to boolean values such as true, to check whether a validator or condition will pass.
The Expression parser test page does not support all field codes Field codes for transitional fields e.g. Transition comment, are not supported.
The expression editor
When you want to test an expression directly in a JWT workflow function or calculated field configuration, you can instantly test and preview the results of in the expression editor.
The expression parser test page
The Expression parser test page is located centrally in the Jira administration: Add-ons → Jira Workflow Toolbox → Expression parser test page.
You want to test a logical expression or calculate a date? You simply want to know which values are currently stored in different issues? On the expression parser test page you can test all kinds of expressions since all Parsing modes are available.
Test adding a field code and play with the different Parsing modes to preview the output!
The Expression parser test page does not support all field codes Field codes for transitional fields e.g. Transition comment, are not supported.
5 steps to test your expression
Type in your expression or select one of the built-in examples.
Click on the Run button 
Select an issue you want to test your expression with.
Confirm your selection by clicking on Run
Check the resulting output or analyze the errors.
Before running your expression against a certain issue, it's recommended to check if the syntax is correct.
The syntax check button shows if the current expression in the input field is syntactically correct
or not 
. The background check runs at least one second after the last input, but you can also push the Syntax button for instant results.
