Same issue with Karma, Mocha and Jest

[rodoabad]

We have the same issue and the only difference between us is that we use mocha instead of jasmine.

Hi @rodoabad, thanks for sharing this. I updated the example with Jest and there is also the same issue.
The test run with Jest w/ jsdom also crashes on memory:
FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory.

These are the results when the proposed solution is applied:

Jest w/ jsdom execution - w/o mem. leaks
	Tests:       3008 passed, 3008 total
	Snapshots:   0 total
	Time:        42.487s
	Ran all test suites.

Karma w/ Chrome execution - w/o mem. leaks
	All 3008 tests passed - 28s 495ms```
