Add Tests

[taylor-stevens]

The fostered-food repository currently lacks sufficient testing. To make automated testing that can verify the working code and make maintenance and debugging easier the following tasks should be completed:

• Add aria-labels for all the components to make sure that rendering is occurring as expected
• Add test files for all the components in the frontend (src)
• Separate out the functions within the server.ts file in the backend
• Add test files for for separated server.ts files.
• Add test files for the util.ts files.
• Add tests for all the components in the frontend (src)
• Add tests for for separated server.ts files.
• Add tests for the util.ts files.
