how can i capture the date while moving the trnsition from one state to anotherstate without pluginn

[pravalika kolawar]

For example if there is a status like 
To Do->Developing->Testing->Done

For the above status we need to track the dates when the status has moved from To Do to Developing and from Developing to Testing and from Testing to Done

Dear @pravalika kolawar,

everything is automatically tracked. Have a look in the history of an issue. If you need to grab this information for a couple of issues (report), I recommend to use the REST Api for this - no plugin will be required.

So long
