90% code coverage via test automation

Problem

Without automated regression testing, it is near impossible to know when new code meant to add features or fix bugs breaks other parts of the app.

Desired solution

Implement test automation with coverage of contracts, backend and front end. Ideally we would have unit, component, integration and e2e tests for optimal quality assurance.

Currently at 20% frontend coverage after #153 Contracts are at 100% coverage
