* First take on running the tests inside an Electron render process * Making progress * Making it possible to override the location of the admin token * Ignoreing the realm-object-server files * Fixing a console.log to return a string instead of a boolean But it should probably be removed entirely * Making the downloaded ROS log less * Adjusting comments in the test.sh * Checking number of windows to determine an Electron crash * Added a test that triggers garbage collection of ArrayBuffers * Enabled the ability to run the tests in Electrons main process * Run tests first in main process and the render * Added a README.md that documents how Electron tests can be run * Added a comment on why the garbage-collection test was added. * Waiting with reading the admin token, until it is actually used * Disabling the GarbageCollectionTests for now

* This test suite is trying to make a bunch of objects with properties of type "data", which will use an ArrayBuffer
|
|
* when accessed.
|
|
* The reason for this test suite is that we have experianced issues in the current version (v1.6.11) of Electron that
|
|
* will crash when an v8::ArrayBuffer is garbage collected.
|
|
* @see https://github.com/electron/electron/issues/2601#issuecomment-135258750
