Add Stress testing

[ouuan]

Is your feature request related to a problem? Please describe.

I can't use stress testing inside the editor.

Describe the solution you'd like

Add a window for stress testing, it has two (or three, including the current solution, maybe sync with the main editor) editors — one for the other solution and one for the test case generator, you can load them from files, maybe load from other tabs. You can set the time limit, and run until finding a diff between the two solutions. The number of correct test cases and used time for each test case can be displayed while stress testing.

Can you consider this high priority?

It is an important feature I think.

[ShizuhaAki]

I think that it can be released as a separate Qt app (cpcompare), and add an option to launch it from the editor.

[nullchilly]

I don't think another app is a good idea

[ouuan]

We need a powerful system, such as generator templates, choose files in the tabs/local files, and add the counter case in the test cases, otherwise, it won't be better than a shell script.
