Separation of development, testing and production environments plays a significant role in achieving the bonding the functionalities of each together. However, the rules for the development of software to convert a testing into a production environment should be distinct and they should be well recorded (documented). A stage or environment is one for testing that exactly the same as the production environment. The testing environment is the actual production environment similar as much as possible. It may get connected to other services, data/database. It applies to any types of environments in software development.
Why is the separation essential?
When a piece of the software is in the testing stage, the development and testing can cause problems. These may include unauthorized chances of accessing the files or the system. The separation level between the production environment and development & testing environments is required to preclude any operational problems.
The separation between the environments should be similar in development and test functions as well. However, this requires a stable and reliable environment. In such a case, the tests can be executed. The environment should be able to prevent unauthorized access.
When the workforce in developing and testing can access the production environment, they may insert untested unauthorized code. Or, they may alter the actual data of the system.
In some systems, the feature cannot put into work if there is fraudulent software or malicious code or code that has not been tested. Such code can lead to severe operational problems. The training of the workforce and using tests can pose a major threat to the confidentiality of information on production.
The development and testing performed may cause inadvertent alternations in the software and information when the users share the same environment of computing. Setting apart resource devilment, testing and operational aspect is, therefore, absolutely essential. It will reduce the risk of inadvertent, accidental or unauthorized access to operational software and data.
To ensure this, consider taking care of these points:
The testing and development activities executed are likely to bring about unintentional changes in the software and information when sharing a common environment.
Separate the development of software and testing as far as possible. Make sure to use them on different processors, directories or domains.
The development and testing activities should be executed separately.
Make sure the production environment accessing process is separate from the access development to minimize the potential error.
Users should be encouraged to use separate and strong passwords for each environment and let the splash screens show the right identification message.
Make sure the editors, compilers and other elements are not accessible from the production environment when it is not required.
The most important issue is that the development of passwords for individual users to access the production environment and in a controlled fashion only for systems that support the production averment. Further, the controls should be made such that the passwords are changed after regular use.
The staging level of a piece of software is one for testing the environment. Testing on the correct testing environment is essential to determine the competence of quality assurance teams to determine accurately how the application will be performing in production notwithstanding any of the types of environments in software development.
