Please explain me [code] with status in square brackets in History

[Shobhit Sharma]

Hi,

As you can see in the following history tab screenshot there are status code in square brackets with the Status changed, like from Todo -> In Progress. Need to understand how they are helpful to extract information from history

As these are changes from one issue to another.

I would like to use these status codes to identify when status changed in history for specific issue.

I need to know that are the exact status code i need to use for the following status: 

Ready for test 

In Test

In Triage

In Review

Done

And please tell me if there are more status codes that are missing.

Thanks

Aman
