But Do You Need Tests to Get the Job Done?

When asked how to run Guard with RSpec using Docker in Rails projects, I found success with RSpec but faced challenges with Guard. Critically questioned on the necessity of all these tools for coding and seeing things run, the reality is that I may not personally need them. However, what if the project isn't solely mine? What if another developer is assigned tasks to resolve? Would they resort to the classic "It works on my machine" excuse? Or opt for skipping testing and pushing straight to the staging team?

I firmly advocate for good development practices and believe in surrounding myself with individuals who can work asynchronously. Testing isn't just about the present; it's about building a solid foundation for future collaboration and project success.
