Run browser tests against a local HttpServer #2825

jonahgraham · 2025-11-28T03:12:35Z

For a while we have suffered with patchy tests due to limited connectivity to external websites when running Browser tests.

This commit brings in a new Http Server based on the now available Java 21 simple web server available in the JDK. This is sufficient to test the various paths currently used in the browser tests, and make them reliable (or at least more resilient against external sites going dark)

Fixes #2804

Fixes #2561

This has as a parent commit PR #2824

The Windows tests I modified are currently failing - I tried to make these new test more robust. For example in the POST test we were just checking that the returned data was "big enough" without checking content. I have changed that to make sure the results are exactly as expected, which works on Linux. But Edge + IE both re-interpret/re-format the HTML leading to comparison errors.

For example: expected: <!DOCTYPE html><html><head> but was <HTML><HEAD><TITLE>.

I also think newlines change too. I'll provide an update that loosens the new requirements I just added.

This new server uses http://localhost:PORT where PORT is assigned per test (standard way using port 0 to get free port).

A while ago all the tests were changed from http: -> https: and this goes back to http:. There is a comment in the code that said:

"please use https instead, http do not work on mac out of the box and your test will hang there!"

But the tests all seem to pass on macOS. I will spin this up on my mac machine to make sure they work locally too.

I can add https to the webserver, but there is a few hoops to jump through to make keys. However I don't think the functionality being tested needs https. In reality we should have some https tests - for example to make sure that failed certs are somewhat displayed to users, but AFAICT there are no such tests today.
