Until now, we didn't have a nice way to check that we expect a specific JS error in the web page.
This PR improves check_js_errors() so that now you can pass a list of error messages that you expect.
It is tricky because we need to handle (and test!) all various combinations of cases:
- errors expected and found / expected but not found
- unexpected errors found / not found
Moreover, JS exceptions now are logged in the special category console.js_error, which means that the printed text is also available using e.g. self.console.js_error.text or self.console.all.text. However, this should never be required and it's preferred to use self.check_js_errors to check for exceptions. This fixes#795 .
Finally, use the new logic to improve test_no_implicit_target.
Yet another refactoring to untangle the old mess.
Highlights:
base.ts, pyscript.ts and pyrepl.ts were a tangled mess of code, in which each of them interacted with the others in non-obvious ways. Now PyScript is no longer a subclass of BaseEvalElement and it is much simpler. I removed code for handling the attributes std-out and std-err because they are no longer needed with the new display() logic.
The logic for executing python code is now in pyexec.ts: so we are decoupling the process of "finding" the python code (handled by the py-script web component) and the logic to actually execute it. This has many advantages, including the fact that it will be more easily usable by other components (e.g. pyrepl). Also, note that it's called pyexec and not pyeval: in the vast majority of cases in Python you have statements to execute, and almost never expressions to evaluate.
I killed the last remaining global store, scriptQueue tada. As a bonus effect, now we automatically do the correct thing when a <py-script> tag is dynamically added to the DOM (I added a test for it). I did not remove svelte from packages.json, because I don't fully understand the implications: there are various options which mention svelte in rollup.js and tsconfig.json, so it's probably better to kill it in its own PR.
pyexec.ts is also responsible of handling the default target for display() and correct handling/visualization of exceptions. I fixed/improved/added display/output tests in the process.
I also found a problem though, see issue #878, so I improved the test and marked it as xfail.
I removed BaseEvalElement as the superclass of most components. Now the only class which inherits from it is PyRepl. In a follow-up PR, I plan to merge them into a single class and do more cleanup.
During the refactoring, I killed guidGenerator: now instead of generating random py-* IDs which are very hard to read for humans, we generated py-internal-X IDs, where X is 0, 1, 2, 3, etc. This makes writing tests and debugging much easier.
I improved a lot our test machinery: it turns out that PR #829 broke the ability to use/view sourcemaps inside the playwright browser (at least on my machine).
For some reason chromium is unable to find sourcemaps if you use playwrights internal routing. So I reintroduced the http_server fixture which was removed by that PR, and added a pytest option --no-fake-server to use it instead, useful for debugging. By default we are still using the fakeserver though (which is faster and parallelizable).
Similarly, I added --dev which implies --headed and also automatically open chrome dev tools.

* seamless --headed support
* add test-integration-parallel and default for GHActions
* simplify the code. Use http://fakeserver instead of localhost:8080 so that it's clearer that the browser is NOT hitting a real server, and use urllib to parse the url. Moreover, the special case for pyodide is no longer needed, it's automatically handled by the normal 'fakeserver' logic
* The page-routing logic is becoming too much complicated to stay as an inner function. Move it to its own class, and add some logic to workaround a limitation of playwright which just hangs if a Python exception is raised inside it
* no need to use a hash, we can use the url as the key
* re-implement the retry logic. The old @retry decorator was nice but a bit too over-engineered and most importantly failed silently in case of exceptions. This new approach is less powerful but since we want to retry only two times, simple is better than complex -- and in case of exception, the exception is actually raised
* improve logging
