DevTools/Hacking: Difference between revisions

Once you've already built Firefox once, and you just want to incrementally update your build with your latest devtools changes, you can run:

* '''<tt>toolkit/devtools</tt>''': Code for the devtools client and server, and all code shared between the front end and client/server. If we are using any third party libraries, or importing external repositories into our tree, those libraries generally live here (eg, <tt>toolkit/devtools/acorn</tt>).

** '''<tt>toolkit/devtools/server</tt>''': Code for the devtools [[Remote Debugging Protocol]] server and transport layer.

*** '''<tt>toolkit/devtools/server/actors</tt>''': [[Remote_Debugging_Protocol#Actors RDP Actors]]. Note that if you're modifying the RDP, you may need to worry about [[DevTools/Backwards_Compatibility|backwards compatibilty with older protocol implementations]].

** '''<tt>toolkit/devtools/client</tt>''': Code for the devtools [[Remote Debugging Protocol]] client.

* '''<tt>browser/devtools</tt>''': Front end user interfaces for our tools. Should be pretty obvious what is what based on the directory names and each panel we have in our toolbox.

   $ ./mach test toolkit/devtools

  $ ./mach test browser/devtools

   $ ./mach xpcshell-test toolkit/devtools/path/to/the/test_you_want_to_run.js

To run the whole suite of chrome mochitests for devtools:

   $ ./mach mochitest toolkit/devtools/path/to/the/test_you_want_to_run.html

To run the whole suite of browser mochitests for devtools (sit back and relax):

   $ ./mach mochitest browser/devtools/<tool>

   $ ./mach mochitest browser/devtools/debugger

To run a specific devtools mochitest:

   $ ./mach mochitest browser/devtools/path/to/the/test_you_want_to_run.js
