A Guide To System Integration Testing
In the context of software engineering, system integration testing is the process of testing whether a software system can coexist well with other similar software. Most of the time, you find that an SIT test comes before a user acceptance test. Additionally, software producers will run a pre-SIT test before the customers are able to do their own SIT test.
How to Prepare for System Integration Testing
When doing system integration testing, planning is very important. Generally, planning falls into three categories:
a. Establishing a testing hierarchy: at times, starting tests on a system that is not ready can be really frustrating and even disastrous. In order to avoid ruining everything in the name of trying to make things better. In order to avoid this, you must establish a testing system that builds from the simple to the complex and also build towards the end user system from the utility point of view.
b. Climatic interactions: the second thing that you are supposed to consider when starting an SIT process is climate interactions. Naturally, buildings are supposed to control the existing climate conditions. For instance, the temperature and humidity in the house cannot be the same as the outside. When setting up for An SIT, you need to have these things in mind. In order to establish how well a system works, you have to test the over a wide range of climatic conditions. This will help you establish what conditions may lead to the dysfunction or total failure of the system.
c. The operating environment: another factor to look into when preparing for SIT is the condition in which the house or other place where the system will be installed will be in when you start using it. Most people do SIT before they finish installing systems such as HVAC and so on. As a result, they are not able to accurately predict whether the system will operate optimally when the new conditions come into play.
Those are the three things that all programmers and end users of software should have in mind when starting the process of system integration testing.
The Benefits of SIT
To start with, when you carry out SIT, you are able to verify the conditions that are necessary for a system to reach optimum functionality, reliability and performance. This assures you of what to expect out of the software system once you have it installed.
The second advantage that comes with SIT is the fact that you are able to detect any system malfunctions or failures that could lead to disaster before the system is handed to the end user. This makes the systems easier to operate with and reduces the chances of there being disappointments coming from the consumers of the software systems.
SIT helps establish whether a new part of the system is going to blend with the rest and if not, the designers get a chance to either remodel it, and make it possible for the systems to work together or look for alternatives.
