Any way to avoid memory leaks with shallowMount in vue-test-utils?

We have a custom unit testing setup for vue that works on Node, Mocha and jsdom package which simulates browser environment (no webpack, karma). We have wrote about 3k specs already (big app with hundreds of components), and now when mocha is running it becomes slower and slower, and eventually the process just hangs. We thought that maybe there is a memory leak in "jsdom", so we changed it to a "domino" (alternative package), but it still hangs.



We checked the heap memory usage and it just keeps growing (up to 1.5 GB!).



So we think that the problem is with either vue or vue-test-utils. It looks like each time we use mount/shallowMount it needs to be destroyed/unmounted after each test to release memory?



Any ideas? Thanks in advance!

  • I just tried to call wrapper.destroy() after each test ends on each wrapper we have, didn't make any difference
