Mochitests

You can use ccdump to dump the object graph into a JSON file within Mozilla's mochitests. This is useful for debugging memory leaks in tests. Once you have the JSON you can import it into the addon UI for graph inspection.

Example usage:

function call_ccdump()
{
  let scope = {};
  let ccdump_path = "file:///home/mihai/src/ccdump";
  Services.scriptloader.loadSubScript(ccdump_path + "/simple-wrapper.js", scope);
  let ccdump = new scope.ccdump_wrapper({
    global: scope,
    ccdump_path: ccdump_path,
  });
  ccdump.save("/home/mihai/ccdump-dbg-memleaks-" + Date.now(),
    function _onCcdumpSave() {
      ccdump.clear();
      ccdump = scope = null;
      executeSoon(finish);
    });
}

Instead of calling finish() in your test, invoke call_ccdump().
