These tests appear to fail for a similar reason on the main repo, so I'm guessing they've been broken for some time.

Do they still make sense @victor-teles? If so, could use your help on this one.

@nhedger
We need to set up a license to get this working, We can use Biome's license from the open source program.

Basically we need to copy the license key file (idea.key, clion.key..) to build/idea-sandbox/config-uiTest directory

First of all, we need to define which license to use 💲😁

[nhedger]

Got it. Happy to share my license if that's what it takes

[victor-teles]

@nhedger Lets use mine, I'll send to you in Discord

Tests are still failing despite having put the license at ./build/idea-sandbox/config-uiTest/idea.key, as the docs seemed to suggest. The log does not appear to say anything about the a missing license though.

@nhedger In addition to this license issue, I'm also having a problem with the test code that blocks this PR.
I've opened an issue in the intellij-ui-test-robot repo
