Is it necessary to test the main.js file in Vue.js project?

While performing unit tests on components is acceptable, after running coverage analysis I have noticed that certain lines of code in the main.js file remain uncovered. This raises the question: should the main.js file also be included in testing?

Specifically, Vue-related lines of code such as:

  Vue.use(VeeValidate, {..
  Vue.use(Vuetify, { ..
  Vue.config.productionTip = false; ..

  new Vue({
     router,
      store,
      i18n,
      render: h => h(App)
   }).$mount("#app");

are among those not covered by our tests. As such, should we exclude the main.js file from our unit testing process?

I appreciate any feedback you may have.

Answer №1

If the primary purpose of the main file is limited to importing libraries, plugins, and creating the main instance, then it may not be necessary to conduct unit tests on it. Any issues at that level are likely to surface during end-to-end testing.
