Tests commonly timeout in continuous integration

[ericcornelissen]

When tests are ran in the continuous integration setup they commonly time out, leading to either inaccurate CI results or having to rerun (sometimes multiple times, up to 8 times) the workflow. This is inefficient and annoying.

This should be improved upon, even if it means slower CI times.
