refactor incremental tests #434

This PR refactors the incremental tests and fixes #433

m-reichle · 2023-07-10T09:39:24Z

Thank you for taking care of this!
This PR fixes my issues described in #433

Only noteworthy change I noticed is in a custom widget of mine (see below), where I just pass a single Node as self.nodes, this now results in an empty <NodeList([]))> whereas before the NodeList would contain my icon.

class CollapseIcon(Widget):

    def __init__(self, view):
        self.view = view
        self.html = view.html
        self.icon = I(
            _class="fas fa-minus-square",
            style={'cursor': 'pointer', 'color': '#3b8b5a', 'padding-right': '5px'},
            events=[CLICK]
        )
        self.nodes = self.icon

It is easily fixed doing a self.nodes = [self.icon] and I'm not sure if it was supposed to work before the change, but I thought I'd mention it since it's a change in behaviour.

Maybe issue a deprecation warning?

Until now we did not issue deprecation warnings but added wrote them to the documentation. It's a good idea to deprecate the Legacy Widget API now, but I think it's a little bit much for this PR because the old API gets used in multiple examples in the documentation. I opened #437 as a base for a follow-up PR.

I think that this test can be split into multiple ones.

Good idea. Done!

Previously, the tests were designed to be incremental so failing tests in low-level components would cancel higher level tests. This way, a failing low-level test would not result in an all-red test-suite where the actual issue is hard to find. This behavior can be achieved much simpler, by ordering all tests from low-level to high-level and stopping at the first error. This patch removes all old infrastructure which implemented the incremental tests, and orders the tests from low-level to high-level, by using numeric file prefixes. After this patch the test-suite has the following stages: 00xx Testsuite tests 01xx HTML Datastructure Tests 02xx HTML API Tests 03xx Basic IO and Rendering Tests 04xx HTML API Browser Tests xxxx Misc Signed-off-by: Florian Scherf <mail@florianscherf.de>

Previously, `lona.html.Node.nodes` would only accept nodes and lists of nodes. This is unhandy when creating custom node classes and using `*args` and `**kwargs` since `*args` are tuples by default. This patch changes `lona.html.node_list.NodeList._reset()` to accept any kind of iterable. Signed-off-by: Florian Scherf <mail@florianscherf.de>

Previously, `lona.html.abstract_node.AbstractNode.__eq__()` would crash when one or both compared nodes where a widget. This patch fixes `lona.html.abstract_node.AbstractNode.__eq__()`, by adding proper compare logic for `lona.html.Widget`. Signed-off-by: Florian Scherf <mail@florianscherf.de>

Oh! Thanks for reporting, that is not supposed to happen. I updated the patch and added two tests so this may not happen again.
