I want to know how many times my sub tasks were changed from one status to other status

[Girish.K]

I have a task in which many sub tasks were added. In the sub tasks some might have cleared the testing and some were failed and assigned back to the developers for checking. In such case I want to know how many sub tasks were assigned back to the developers based on the status. How to achieve this?

You can use Jira Rest Api with changelog paramter. You can find more info here:

Hi Girish,

you have to create a custom field for the parent and every time a subtask is transitioned back from test to development, increment this field.

But I don't think, this is possible with jira out of the box. You could do this with the Jira Misc Workflow Extensions:

• create a new numeric field, add it to your parent's issue type
• Add a new transition to each of the parent's status, call it e.g. "increment", then add a postfunction "increase value of field" to this transition
• If a subtask is transitioned back, use the "transition parent issue"-function and fire the "increment" transition.

There may be other apps also, please have a look at the marketplace.
