To ensure the software or application performs as expected when released to end-users, it is crucial that the production and test environments are similar. This is because significant differences between the two environments can lead to issues when deploying the application to the production environment.
If the testing environment does not replicate the same conditions, configurations, or constraints present in the production environment, problems can arise. By making sure that the test environment closely mirrors the production environment, software developers can detect and address issues early on in the development process, reducing the possibility of problems in the production environment. This ensures that the application operates seamlessly and meets the desired quality standards for end-users.
