Meaningful unit test coverage - Layout

[ryanbellison]

Problem

As part of issue #59, all snapshots tests where removed. We would now like to replace these snapshots with a more meaningful unit test.

Acceptance Criteria

Using @testing-library/react create a test for Layout.js found in src/components/Layout/

Hey there, I can take this one. Which cases need to be covered?

Hey @bagshik, we are leaving the coverage choices up to the contributor - whatever you think is useful coverage feel free to do that.
