* Avoid as much as possible creating and destroying objects for each test.
|
||||
* Instead, try re-using them, except for the ones under test of course.
|
||||
* PhantomJS does not perform garbage collection for the life of the page,
|
||||
* i.e. during the entire test process (Karma runs all tests in a single page).
|
||||
* http://stackoverflow.com/questions/27239708/how-to-get-around-memory-error-with-karma-phantomjs
|
||||
*
|
||||
* The `beforeEach` and `afterEach do not seem to cause much issue.
|
||||
* => they can still be used to initialize some setup between each test.
|
||||
* Using them keeps a readable spec/index.
|
||||
*
|
||||
* But refrain from re-creating div and map every time. Re-use those objects.
