Create mock tests

[hsorathia]

Research some testing libraries that we can use for our application. Two primary contenders that I was thinking of are

1. react-testing-library
2. jest

There's some positives to both of them. Try and see which one would be easier to use, see if there are any preferences (amongst anyone else on the team), and then add it to our repo.

AC:

• Add the testing library to our repo
  • Find out if there are any types associated with the library
• Add a mock test (test a dummy react component)
• Get tests to run on a push event

Add a testing subdirectory under the root directory called __tests__ , and we will dump all of our tests there
