In api/feeder_test.go, we have three main test case scenarios:

• To test if a unique hash is generated for each new document
• Testing if payload sent to the /api/feeder endpoint returns document content as expected
• Test to ensure the indexing of documents is working as expected

The following is the expected output after running the tests:

    $ go test -v ./...
