Write more tests

[ascibisz]

What needs to happen?

Good test cases to have:

• that the correct default values are being displayed per recipe
• that switching between recipes resets fields as expected
• that switching between gradients holds changed values as expected
• logs are displayed on failure
• job status renders properly
• probably more things?

@rugeli and @interim17 work together to break this out into some smaller and more specific tickets / subtasks for what tests are top priority and what tools we should use
