Testing

Topics: Software development

Software tests check whether code behaves as expected and help detect regressions.

“Regular testing ensures that new features, refactors, or bug fixes do not introduce unforeseen issues or regressions. It’s a proactive approach that bolsters the reliability of applications and, by extension, the trust of end-users.” (Jeffery Morhous, FactoryBot for Rails Testing)
