To begin, first run npm install to make sure all dependencies are ready.
There are 6 tests, each under /test-{word number} route (ex : /test-one; /test-two; /test-three)
You will find the sources for each test under ./src/app as test-0{number}.ts (ex : src/app/test-01.ts; src/app/test-02.ts) and each files contains, at the top, the requirements for each test.
