In the Ruby community, there's near-unanimous agreement on the importance of testing. Tests act as a safeguard, ensuring that the digital experiences we craft remain consistent, reliable, and of high quality. Many in the Ruby community claim that no code change is complete without tests. They are an integral part of the development workflow. Regular testing ensures that new features, refactors, or bug fixes do not introduce unforeseen issues or regressions.
