"collectCoverageFrom": [ I'm sure I'm missing something obvious but I have no idea what it is.I’ve just upgraded to jest 16, and since my test coverage are empty. I realise that the mock will never work whilst set to 'Anything' but I expect to see it set to the mocked value at least.Īccording to the Jest documentation () on Automatic Mocking I think the above is correct. To be able to run the tests with the reporter locally, environment variable should be set: export TEAMCITYVERSION'someversion'. What I expect to happen is that the eventBus instance inside the component is replaced. Add this into the jest configuration file: 'reporters': 'default', 'jest-teamcity' The reporter is enabled only if TEAMCITYVERSION environment variable is set.
If I try and console.log(eventBus) inside the test, it is undefined too, which i just don't understand either.
The console.log(eventBus) inside the component's created() function also yields undefined. The exact error is as follows: TypeError: Cannot read property '$emit' of undefinedĪt (src/invite/accept.vue:49:23)Īt callHook (node_modules/vue/dist/:2919:21)Īt VueComponent.Vue._init (node_modules/vue/dist/:4628:5)Īt new VueComponent (node_modules/vue/dist/:4796:12)Īt createInstance mount Object.shallowMount createWrapper (test/invite/accept.ts:13:29) The test called should mock in component does not get the mocked value for eventBus and it is undefined. The test called should mock in test gets the mocked value for eventBus and passes. Import from VueRouter = require('vue-router') // This needs to be 'require', rather than 'from'. Import Component from 'vue-class-component' Src/invite/accept.ts: import Vue from "vue" I've been observing some strange behaviour when attempting to mock out a dependency module using Jest.
