Tests!

Right:

1. Run npm install this should hopefully work and will get playwright and JEST installed
2. the tests are in the imaginatively named __tests__ directory and inside are the unit & integration tests and the E2E tests
3. the unit tests just test some schemas and the integration tests test more advanced components
4. the e2e tests act as users and perform actions, this is good for testing both back and front-end
5. to run the unit & integration tests individually do npm run test [testFileName]
6. to run the e2e tests run npx playwright test [testFileName]
7. I would advise running the researcher e2e test before the e2e admin test as it opens a new study request with fake data
8. hopefully this is enough tests, there are very minor fixes to the code in here as well, but all in all everything worked, apart from some of my parts lol, so we are in good stead I think 😎
