Looking through the stack trace I see this.$q is undefined when the LoadingBar plugin tries to install:

https://github.com/quasarframework/quasar/blob/e9b85566b01250732532c3e053ae82f8795cf1d8/ui/src/components/ajax-bar/QAjaxBar.js#L131

I’d imagine this is because the tests are using createLocalVue and therefore Quasar ($q) has been installed on the localVue but not on the instance created below:

https://github.com/quasarframework/quasar/blob/c484aa12e4561ff6b9867abd6213eee612e7013f/ui/src/plugins/LoadingBar.js#L23

One way around this (that’s worked for me) would therefore be to Vue.use(Quasar) to install Quasar globally before using createLocalVue.

However given that the installed Quasar $q is available in LoadingBar.install, I wonder whether it can be in some way used in the new Vue constructor; or indeed whether the localVue could be used in place of the Vue (although I don’t see a readily available reference to the localVue within that scope), thereby avoiding polluting the global Vue.

I have hit the same issue when testing components in my project. I can, however, mount the App without issue.

Has anyone else found a solution?
