Potential memory leak?

[maxs-rose]

After running ~2K tests the JS heap reaches 1GB of memory usage and no longer goes down.

There appears to be a lot of detached dom nodes handing around that seem to be related to ngMocksUniverse

Most of the test are setup similarly to the following:

describe("some component", () => {
     ngMocks.faster();

     const someServiceMock = MockService(SomeService);

     beforeAll(() => {
         return MockBuilder(SomeComponent).mock(SomeService, someServiceMock);
     );
     
    it("should do something", () => {
         const component = MockRender(SomeComponent).point.componentInstance;
         
         component.foo();

         expect(someServiceMock.serviceMethod).toHaveBeenCalled();
    });

    /* some more it blocks */
);

We have tried removing ngMocks.faster but that doesn't seem to have any affect.

Is this behavior due to how we are using NgMocks?

Hi there, thank you for the question. I've converted it to a bug and try to investigate next weeks where the problem might be.
Could you verify if you remove ng-mocks completely from test env, then you don't see the issue?

I am not sure how I would do that without rewriting about 2K tests 😅

oki-doki - I'll try myself
