How to count number of defects for specific change request?

[Maulin Rathod]

We want to find out number of defects raised against particular change request. How can we do it?

Hello,

You can create a new custom field, which would show you this information. You can use the Power Custom Feilds add-on. It is a free add-on.

Suppose, you link all bugs for a request with the Bug link type. The code for your custom field would look like this:

 return linkedIssues(key,"Bug").size();

Thanks for Reply....In our scenario we have change request and QA team is creating subtasks (issueType = Defect) of change request. we want to calculate number of defect raised for that specific change request. Do we need to manually link subtask (issueType = Defect) with parent Change Request ? I guess there must be some automatic link between Change Request and its subtask (issueType = Defect).

If you create a subtask, then you do not need to add more links. Your script would look like this:

return subtasks(key,"Bug").size();
