PHPUnit tests failing

I have issue with tests as well. I think the solution may be to resolve the issue rather than to disable the tests. Problem looks similar to https://www.drupal.org/project/restui/issues/3310517 →

i.e.

 - protected function setUp() {
 + protected function setUp(): void {

Hmm, I see for some reason the latest changes are not in the diff here https://git.drupalcode.org/project/remote_stream_wrapper_widget/-/merge_...
?

The changes so far in the MR are just re-enabling the tests so they will fail the test run. The work here is to resolve the two failures:

There were 2 failures:

1) Drupal\Tests\remote_stream_wrapper_widget\Functional\RemoteStreamWrapperWidgetTest::testBasicFunctionality
Failed asserting that 404 is identical to 200.

FAILURES!
Tests: 2, Assertions: 18, Failures: 2.

Error is worse than a failure
