This section of the tutorial guides you through writing a conditional statement that compares the value of a field against a String. Imagine a functional use case where you want to allow the progress on an issue only when the issue is assigned to the logged in user. For this you will need to write a Groovy condition in the Scripted (Groovy) condition to compare the usernames of the Assignee and the logged in user. 

Writing the script

Step 1 - Navigate to the condition

1. Go to the Administration icon  and click on it.
2. Go to Issues - > Workflows
3. Locate the workflow GIJ: Process Management Workflow
4. Edit it
5. Click on transition Start Progress
6. Go to the Conditions tab
7. Edit the Scripted (Groovy) condition which is the first condition in the list.

Step 2 - Write the script in the condition

1. Write the following script in Groovy script.

   
   

   Code Block
   language groovy firstline 1 linenumbers true
   issue.get("assignee").name == currentUser.name

   ---

   (1) Accessing the assignee of an issue using the get() method and fetching the name of the ApplicationUser using .name

2. ---

   Your configuration should look like this:
3. 

Step 3 - Test your script

1. Click on Test Groovy Script.
2. Input the issue key GIJ-5
3. Click on Test
4. The following result will be displayed.
5. 

Step 4 - Save the configuration

1. Click on Update
2. Publish the workflow (you don't need to save a backup copy).

Step 5 - Test it on an issue

1. View the issue GIJ-5 in a new tab.
2. Check that the transition Start Progress is not available for a trigger on the issue GIJ-5.
3. Click on Assign to me, to assign it to the logged in user.
4. Check that the transition Start Progress is now available for a trigger on the issue GIJ-5. 

Use cases

The output of the code is a Boolean. You can use this script in any other relevant context, such as allowing only the reporter of the issue to close the issue.

Step 2 - Write the script in the editor

1. Write the following script in the editor.

   Code Block
   language groovy linenumbers true
   if(issue.getAsString("priority") == "Critical" || issue.getAsString("priority") == "Highest"){ return true } else{ return false }

   
   

2. Your script will look like this:
3. 

Step 3 - Test your script

1. Click on Test Groovy Script.
2. Input the issue key GIJ-3
3. Click on Test
4. The following result will be displayed. 
5. Image Modified

Step 4 - Simplify your script

You can simplify the script removing the if-else and returning the result of the comparison which is a Groovy truthy or falsy

1. Go to the editor

2. Replace the script with the following code:

   Code Block
   language groovy linenumbers true
   issue.getAsString("priority") == "Critical" || issue.getAsString("priority") == "Highest"

   
   

Step 5 - Retest your script

1. Click on Test again.
2. The following result will be displayed. 
3. Image Modified

Use cases

The output of the code is a boolean value. You can use this script in any relevant context, such as, Assign the issue to the Project lead only if the priority of the issue is Critical or Highest.

...

1. Go back to the previous tab.
2. Edit the workflow in Diagram mode.
3. Click on the Create transition
4. Click on Post-functions
5. Edit the second post-function in the list.

Step 2 - Write the script in the post-function

1. Write the following script in Value.

   Code Block
   language groovy linenumbers true
   def impact = issue.getAsString("impact") switch (impact) { case "Company wide" : "Highest"; break case "More than one project" : "High" ; break case "Single project" || "Individual" : "Medium" ; break default : "Medium"; break }

   
   

2. Your script should look like this:
3. 

Step 3 - Test your script

1. Click on Test Groovy Script.
2. Input the issue key GIJ-5
3. Click on Test
4. The following result will be displayed.
5. 

Use cases

The output of the code is a String representing the priority of an issue. You can use this script in any relevant context, such as, setting the priority of the issue to based on the Component/s.
