Support for a built-in browser runner

[junior-santana]

Is there a plan to support running the tests in a browser with a built-in browser runner?

Scenario: In a VueJS project, we can mount components which will be the subject under test, then have the full context of a browser to interact with them and test how they behave and render.

It's a little more than unit testing, but far from E2E.
I'd rather keep using a real browser instead of moving to virtual DOM options, so a transition would be smoother.

Is there a plan to support running the tests in a browser with a built-in browser runner?

There are some interesting challenges in this process:

• How to handle file imports (e.g., fs)
• How to handle processes (e.g., spawn)
• And, basically, all features derived from the backend runtime (Node.js, Deno, Bun, etc.).

Apart from that, there is a different plan, but not exactly that one: create an ecosystem with extensions such as @pokujs/react, @pokujs/vue, etc.

But they still wouldn't run in the browser, but rather in the terminal (without the need for compilation).

@junior-santana, could you share an example of how it is done currently or how it would be used in practice? This would help to think of an approach to make it possible (or study its feasibility) 🙋🏻‍♂️

To be clear, I haven't used poku (yet), so I don't have the full context here.
Let me know if that doesn't fit the tool's goals.

I assume when running in the browser, we have to compromise a few things.
Running all tests sequentially in a single process sounds fine to me.
Also, since the production code in this case is meant to run in the browser as well, backend APIs could be omitted (and, conversely, browser-only ones would be available).

Currently, the setup we have uses Jasmine + Testem.
JS is bundled via webpack.
Testem serves (on localhost) the HTML file and JS files and spins up a browser to run the tests.
The configuration and overall usage are awkward and sluggish.
Jasmine has its own runner (jasmine-browser-runner), which would likely simplify a lot, without requiring too many changes, but as I'm looking into alternatives, I bumped into poku (Fernanda Kipper's video brought me here) and was curious if something similar could be done with it.
