Wrapper from vue-test-utils not exposed?

Hi, I wanted to call something like wrapper.isVueInstance() like I would with vue-test-utils. Looks like this wouldn’t be possible in this library? Thanks.

Hi! 👋 and thanks for your question.

Vue Testing Library tries to follow the Testing Library Guiding Principle. Since we are trying to focus on rendering components instead of dealing with component instances, it wouldn’t make much sense to provide a tool that helps testing you the exact opposite - if a given wrapper is a Vue instance.

That’s the reason behind not providing such method.

In Vue Testing Library world, I’d just render the component and assert that the “initial state” is already there - the default strings, values, and so on.

Hope I helped!

VTL exposes a render() method that contains DOM Testing Library queries + some vue-test-utils methods too: https://testing-library.com/docs/vue-testing-library/api So, in theory, you are mixing both libraris.

The idea is that by using VTL you get the tools to test your components far from implementation details, so if you feel the urge to use a non-exposed method, I believe you’ll find an available one that suits your needs. If not, let us know! 😉

Thanks for your questions! Feel free to open up another issue if anything is unclear while using VTL 😄
