Integration tests about prefresh

Just thinking about this more (still trying to get the current tests running on my laptop), do you think it might be worthwhile having a look to have a common set of test cases and run the same ones for each bundler? Something like the following:

[vite, snowpack, nollup].forEach(engine => {
    beforeEach(() => {
          // start dev server
     });

    describe('some test case', () => {
         it ('should update');
    });
});

Would reduce a lot of duplication. Fixtures might have to be duplicated though because of different index.html files though. Or do you think it would be better to keep tests separate for the time being?

I think there's value in having a general test suite so we can test it all at once but it's going to be really hard to find the right abstraction to make all integrations work.

I do think that if we have like:

packages/
test/
  fixtures/
    webpack-dev-server/
    nollup/
    vite/
    ...
   test.js

It could work (implemented in #165)

having some issues expanding into other suites but we're getting there #166
