Add test fixtures using rector

[jtojnar]

Use composer rector (or composer rector -- --dry-run) to run the automated refactoring.

[j0k3r]

Maybe you can separate the code improvement (fn, ??, etc.) in a separate PR to reduce the noise?

[jtojnar]

I can separate them out but then CI will not pass. It should still be feasible to review commit by commit.

[jtojnar]

Or I can move the ci commit to the new PR too.

[jtojnar]

Removed the ci part for now.

Still need to replace file_get_contents with actual fetchContent and capture the resources.

[jtojnar]

I got nerd sniped quite hard by this but I had this on to-do list for few other projects. Now running composer rector should automatically add fixtures for fetchContent calls on Graby constructed without a second argument.

[jtojnar]

Rector is a tool for automated code transformation. The transformation rule runs Graby and extract headers using RecordingHttpClient will also update the functional tests – the last commit is fully produced by the transformation rule without any manual changes.

[jtojnar]

If you check out the PR, you can try it yourself by removing the last commit and running composer rector. (Comment out this line if you do not want the code modernization.)

[j0k3r]

Can you rebase against the master? And it'll be good to merge

[j0k3r]

Good job @jtojnar 👊
