What is the staging environment?
A staging environment is essentially a close replica of the live product that is used by developers to test the software.
Staging environments are necessary because they let developers discover and eliminate issues that could potentially lead to performance and security issues for users.
A staging environment shows how the software will work in a live production environment, the staging environment must mirror the same servers, databases, and configurations.
What is a UAT environment?
UAT is a part of the staging environment where a small group of people test the software and provide feedback about real use cases. There is no limit to the number of users testing the software. However, 5% of them should provide ample feedback for the development team to make changes.
What makes staging different from UAT?
Both the staging and production environments are very similar, but in reality, they are completely separate. In a production environment, roll-outs and roll-backs impact direct users. On the other hand, in a staging environment, the user isn’t impacted at all, which gives software testers more freedom to make changes.
Smoke testing, aka build verification testing, is an analysis that is done to verify that the critical functions of the program are working properly. This test ensures that the software is operationally sound.
Chaos engineering is simulating potential failures in a program in a secure testing environment. By conducting such an analysis, engineers can identify any potential issues before they arise, thus improving the uptime of the program.
User acceptance testing (UAT)
UAT is the last stage before software goes into production. In this stage, engineers check to make sure that the software can handle real-world functions and meet user expectations.
Disaster recovery testing
The first stage in the production process, disaster recovery testing, involves how well the team can recover data and restore operations after an outage. This test is extremely important for developing resilient applications.
Visual regression testing
System changes can interfere with existing software features and can also disrupt the user experience. To eliminate any inconsistencies, engineers utilize visual regression testing and ensure to provide the best visual experience to the users.
A/B testing is the method of comparing two different rollouts with minimal changes to find the best version. Because there is live production traffic available, A/B testing works best when used in the production stage.
