Testing end to end

At this point, we have performed tests on individual pieces of code and ensured the correct functionality while maintaining security. Here, we start to integrate the new changes of code with the existing code base and evaluate the system as a whole by testing the system end to end.

The practices that allow for true end-to-end testing of the system will be examined in the upcoming sections. Let’s dive in.

Equivalent test environments

System-level testing should be performed in an environment that resembles the production environment as closely as possible. Testing the solution in an environment with as many similarities to the production environment as possible enables higher confidence that the solution will work when actually released into the actual production environment. The more similarities a test environment has with the production environment, the fewer variables come into play when problems are found and troubleshooting for the root cause...
