Description

As a developer, I want to be able to use React Testing Library to easily write good tests for my react components.

Acceptance Criteria

1. Should add React testing Library as a dependency in console.
2. Should write some good unit tests for components using the library.

Additional Details:

Initially we can start by writing tests for `EditDeploymentForm` as it is one of the most complex forms and we can make good use of React Testing Library and cover tests for all complex scenarios which will serve as a reference for writing tests for other components.
