Can Eclipse CodeCover be started later during execution, not from very stard of app?

[lufi...@redhat.com]

Hello (Привет!),

I'm an SWT/Eclipse developer, trying to fix a difficult Tree-editor drawing issue.

I have a situation like this:
A) <Boring Init Code>
B) <Problem Code that goes into JNI and back to java many times>

I need to figure how what lines are covered by the *problem* code, but not by Init.

I would like to do something like:

A) <Init Code>
- Turn on Cove Coverage
B) <Problem code>

Is this possible?


I've tried to sleep code and dump state, but it dumps everything up to problem code(A). When dumping again the "Init code" is included. (i.e we have A+B, but I need only B).

I've tried to do two runs (A+B) and only A and export via html. But the html have different time stamps so it's hard to tell the actual difference :-/. (I'm considering writing bash scripts to change that...)

Please advise.

In the coverage view check the "Reset on dump" option of the "Dump
Execution Data" drop down menu.

Then request a dump after boring A) -- you can probably ignore that.

If you create a dump after B) you will only see the executed code after
the previous dump.

Hope this helps.

Cheers,

Salut, Leo!

This time Marc was faster than me with answer :D

Just in case, as addition, here is a link on recording from EclipseCon France 2017 where this demonstrated in action - https://youtu.be/BoiVrdlxB_M?list=PLZRu6Rvmk66uNscSsWjx9W6LiBSYFghW3&t=899
