**Construction and Maintenance of the Test Environment**
If you've ever done testing, you know how important the test environment is. But how exactly is it set up and maintained? Not everyone has a clear understanding of this process.
Each company may have its own way of building and maintaining the test environment. In some cases, operations or development teams are responsible for setting it up, while in others, testers themselves take on this task.
Most complex test environments are typically built by developers because they have the necessary knowledge about configuration files and system paths, which makes the setup easier. If operations are in charge, they usually follow an installation manual provided by the development team. This manual often includes standard procedures for maintenance. When testers are responsible, the process is similar to that of operations.
An installation manual is crucial, especially when multiple environments exist—such as development, functional testing, and performance testing. Even if the manual is written with effort, it might not be used much at first. However, without it, any issues that arise would be hard to resolve quickly. The manual should also be updated regularly as the environment evolves.
When getting the installation manual, for Linux systems, you can either use Jenkins or write custom Shell scripts to automate tasks like copying files, starting services, updating logs, or running SQL commands to apply new database configurations. If disk space becomes an issue, you can delete old logs using the paths specified in the manual. If scripting isn't feasible, manual updates can still be done, though they are less efficient.
That’s why many recruiters look for candidates who are proficient in Linux and understand databases—because testers may need to build and maintain their own environments. In larger testing teams, a configuration administrator often handles this, which helps improve their Linux and database skills.
Once the test environment is built, it should ideally mirror the production environment as closely as possible. Small companies may scale down if resources are limited. For example, a three-tier architecture (application, cache, and database servers) can be simulated with two of each layer. While this doesn’t fully replicate a distributed system, it still allows for meaningful testing.
Finally, a reminder: just because something works in the test environment doesn’t mean it will work in production. There are always differences between the two. That’s why a staged release is often used—first sending a small portion of users to a gray version, then performing smoke tests or tracking tests before a full rollout.
