I'd like to help with this. I've been looking at some performance improvements to the tests and also making them more reliable.

[rcowsill]

To start, I'd like to make pull requests for two fixes that should resolve the signup test flakiness:

• Make db-reset.js wait for dropCollections to complete before inserting new data
• Set necessary env vars in docker-compose.yml to make the web service use the mongo service (instead of mongolab)

The first one affects branches master and feature/187. The second currently only affects feature/187, because master isn't using docker in Travis.

I have more to follow, but these are higher priority because they make the tests reliable. Making these changes should save a lot of time looking into false build failures.

@UlisesGascon, which branch(es) would you prefer the pull request(s) to be made against?

Pull request for the dropCollections fix is open: #214

[rcowsill]

To start, I'd like to make pull requests for two fixes that should resolve the signup test flakiness:

Both these fixes were merged into master in c44bbd6.

The fix to set MONGODB_URI in docker builds needs to be merged into feature/187 before January 12, 2021. On that date the mLab database currently used by CI in this branch will be shut down, causing all subsequent Travis jobs to fail.

Just made PR #230 which adds video recording/upload to the github actions CI workflow.

Video recording is off by default for local test runs, but can be activated like this if needed:
npm run test:ci -- --config video=true
or:
npx cypress run --config video=true
