As long as you have done a test, you must know the test environment, but how is the test environment built and maintained? Not everyone understands it.
The construction of the test environment, each company has a different process and method. One is that operation and maintenance or development is responsible for construction and maintenance, and the other is for testers to build and maintain.
Most of the complex test environments are built by developers, and development knows which path to take any configuration files, making it relatively easy to build. If it is an operation and maintenance construction, it must be built and maintained according to the installation manual provided by the development. There is usually a fixed maintenance method in the manual. If it is a test build, it is actually similar to the operation and maintenance.
The installation manual is very important, especially when there are many environments, such as a development environment, a functional test environment, and a performance test environment. Although it may be written for a long time, it may not be seen by anyone, but if not, once there is a problem, there is no way to maintain it in time. The installation manual will continue to be updated over time.
Get the installation manual, usually Linux system, you can rely on Jenkins or independently write a bunch of Shell scripts to automatically execute: copy the installation file to the specified directory, the service to do a startup, log to do an update; if accompanied by database configuration, to perform some SQL, make the newly configured data take effect; if you encounter the server hard disk is not enough, you need to delete the useless test log according to the log path in the manual. If the level is not enough, the shell script will not be written, or the compilation or copy command update or maintenance can be performed manually, but the efficiency is not high.
This is why some recruiters need to be proficient in Linux and understand the database. It is likely that testers need to customize the build and maintain test environment. Large-scale test team, configuration administrator to undertake the operation and maintenance of the test environment, which has a good effect on personal training Linux operations and database knowledge.
When the test environment is built, it should be as consistent as possible in the online environment. Small companies can scale down if they have no conditions. For example, a set of environments has three layers: application server, cache server and database server. You can take two of each layer and basically simulate the distributed structure. It's not working, and every layer can be used, but this can't simulate distributed, it depends on the quality of the test.
Finally, there is a reminder: there is no problem in the test environment. Is there no problem after going online? The answer is obviously no. There is always more or less difference between the test environment and the production environment. Therefore, the online environment first sends a grayscale version. After a version of the smoke test or some tracking tests, it is safer to officially release it.
