Approach

Some "accessors stretch" was made to accommodate the testing.
Despite some enums were CaseIterable, I was unable to access to the allCases so I ended up re-adding them into the tests.

Added the following tests

• "Learn" more tap on the About Ecosia section
• Top site actions
• Multiply Impact screens (referrals)
• News items and detail screen view
• The whole onboarding flow

For the nasty issue with linkCopying test, I realized there is something wrong with the .touchUpdInside event only when run in CI. I removed it for now as we may find another solution later. I didn't want to keep the test but skipping it as it could be easily missed so when continuing with Analytics Integration Test we can find it still as "to to".
My suggestion is to review that component altogether and make it as a UIButton so that we can guarantee reliability. If you agree I can make a ticket out of it.

Other

• It also aims to standardize the comments throughout the testing functions

Before merging

Checklist
