QUESTION
I'm using vuejs, vue-testing-library, jest, axios, and axios-mock-adapter to test a component. I'm immediately running into the following error when trying to run my test:

Answered 2022-Mar-26 at 16:05MockAdapter is a default export, so remove the braces on the import statement:
import MockAdapter from 'axios-mock-adapter';
instead of:

QUESTION
When testing a base button implementation using Jest and Vue-test-utils, the tests work but I am getting the following warning:
[Vue warn]: Unknown custom element: b-button - did you register the component correctly? For recursive components, make sure to provide the "name" option.
I am confident is because I am not including the Buefy plugin dependencies correctly, and I don't have a lot of experience here.
Here is my single file component for the base button:
ANSWER
Answered 2022-Feb-05 at 05:12To include the Buefy plugin (or any other plugin), you can use something like const localVue = createLocalVue() from vue-test-utils to create a local vue and use the Buefy plugin, localVue.use(Buefy) as below. This localVue can be included when mounting the wrapper.
QUESTION
I have a strange problem with testing the frontend part of my project. I use Vue components for the frontend. The project is website for teachers to set appointments for the assistent(s) so the assistant can ready everything for class.
First let me explain the structure.
I have a component which lists all appointments by date. Every date is a seperate card and all the appointments for one date are rows on that card. Each row is a specific timeslot. Appointments can be added to the list either by clicking on a button at the top of the card or by clicking the row number.
So I created three components: AppointmentsList.Vue which gets the appointments from the backend and builds a list of the cards, AppointmentsCard.Vue, which receives the date and all the appointments for that date as props, and lastly AppointmentRow.Vue which show the detailsof the appointment in a row of the table. The state, appointments, requested dates and other data, is kept in a Vuex store.
I build the project using TDD, using Jest and Vue-test-utils for writing the tests. Mocks are used to simulate the responses of the backend. Tests showing the appointments with the cards and rows works fine. But when testing the buttons I encountered a strange problem.
In the following code I show you my tests, redacted for brevity. First everything is imported and then the responses of the backend for varieous endpoints are defined. Only the appointmentResponse is important. Note that two appointments are returned.
The function createStore builds a store out of the modules. I keep all state, getters and mutations in modules. Before each test is run, I create a new store and initialize the store with the data of the responses using the mutations of the store. After each test the jest mocks are cleared and the vue-test-utils wrapper is destroyed.
...ANSWER
Answered 2022-Feb-04 at 18:17I solved the problem. When storing the response from the backend I replaced the array in the vuex.state with the new array, thereby breaking reactivity. When I use

QUESTION
I am new to component testing and Cypress. I have been following the official documentation and examples to do some basic component testing on my project. Eventually, I stumbled upon a case where I wanted to test a simple component I wrote which accepts a single slot (default) and since it was awfully similar to an example provided in the @cypress/vue repository, I took the liberty to copy the code and adjust it to my liking.
However, while the first test passes and mounts without issue, when I try to mount the component being tested passing it a default slot, I get a type error with Cannot convert undefined or null to object. Since then, I went through Vue and Vue-Testing examples and I do not seem to figure out what I am doing wrong when invoking the mount function. Below are my code snippets for the souls who can help me on this one.

I'm trying to implement some Testing Library tests on a Vuejs app, but I can't figure out how to pass props to a component within the test.
For example, I want a unit test for a component that appears inside of its ParentComponent template like this. I am trying to write a unit test for the ChildComponent.
...ANSWER
Answered 2021-Nov-11 at 23:47Testing Libary's render() is a wrapper for Vue Test Util's mount().
The second argument to render() is passed onto mount() as mounting options, and mount() can set the component's props with the props option (in version 2x) or propsData (in version 1x).
So your guess is actually correct:
