问题 I'm using Angular 5 with Jasmine and Karma. I'm trying to test whether a certain function works but my subscribe doesn't trigger during unit testing. this causes my unit test to fail as I'm using the done function of jasmine. I want to make this unit test succeed. I've set the timeout interval to 20 seconds to see if it just took a while (which it shouldn't). I've tried to use async and fakeasync as well, but it doesn't trigger. Is it possible for me to make the subscription to trigger? this
