Software means a number of features and functionalities combined within a single setup. And, you surely know how the modern world is desperately running after more and more features and functionalities that will make their tasks easier and will provide an amazing work efficiency. But, from a technical perspective, more efficient features normally mean more complex codes and eventually more vulnerability towards breaking down. And, even if the features work fine when only one of them is used at a time, they may break while having some interdependency. And, that makes us look at the issues that you may face due to the incapability of the units to properly depend on each other.
All these issues can be avoided just by moving your application through rigorous Integration tests. It is the definitional name of the testing process that primarily checks whether the units/modules of your application are performing as expected when they are interacting with each other or at least somehow dependent on each other. You have already known a lot about Integration Testing in the article “What Is Integration Testing? Definition, Basics, and Types”. It’s time for you to know how to proceed with this crucial phase of the testing pyramid.
Till now, you got to know about the possible problems that may occur in the absence of Integration testing. But, to convince the world more about its essentiality, we must check out why it is so important.
These points clearly show how you must sincerely execute Integration tests when they are necessary for the product’s journey. Now, let’s move on with what your suitable approach to those tests should be.
In the article “What Is Integration Testing?”, you can see the types of Integration Testing according to the approaches followed to accomplish them. But, Integration testing is primarily categorized into two types according to their objectives. Let’s get to know them in detail.
You surely know how focused attention does wonder in anything. Similarly, when you put the absolute focus on testing only a handful of components working together for completing any operation within your application, the results come out to be more accurate. That’s why this specific type of testing that deals with particular modules involved in any operation is a popular type of integration testing with the name “Component Integration Testing”.
For example, calculating your order value according to the preferences you make about the order involves only the specific options/components you interact with.
A lot of functionalities in your application need to interact with external systems and different modules from those two or more different systems get involved. The purpose of System Integration testing is to ensure that the overall system that is working with the involvement of different modules from different systems, is working properly. Hence, the scope of this type of integration testing is larger than Component Integration testing and it holds a remarkable level of importance.
For example, during the calculation of the overall cost of any eCommerce order, the applicable taxes need to be fetched with the help of an external ERP system. Here, modules from two different systems are involved.
A practical example is much better to understand any complex process. So, from the perspective of the eCommerce tax calculation, a brief about Integration testing is added below.
A retailer using an eCommerce platform needs to go through a number of operations like inventory management, supply chain, CRM, Finance, Reporting, etc. And, an ERP system is responsible for building a strong foundation for all those functions. Hence, you must stay acknowledged of the following checkpoints involving an ERP system.
Though in present times, the amazing software testing tools like PreFlight enable you to test all your tech products within seconds, and even without having any coding knowledge, you must know about the traditional method that is being followed for System Integration testing.
The most common method of performing System Integration Testing is the Data-Driven method. The steps in this method include data exchange i.e. data import & export between the system modules and observing the performance of each data field within the individual layer. After the integration of the software is completed, the following three states of data flow can be observed.
The integration layer performs the role of an interface between the data import and export. If you are planning to perform System Integration testing at this layer, you must know a bit about certain schema technologies. To validate the data exchange at this layer, you have to follow these steps -
As we are talking about databases, SQL is a must mention here. Hence, to efficiently perform System Integration testing at the database layer, you must have some basic knowledge about SQL. Let’s check out the steps you need to follow for validating data exchange at this layer.
Performing System Integration testing is comparatively simpler at the Application layer. You just need to execute the following steps.
Till now, we mostly discussed the traditional methods of Integration testing. These methods have been used since the initial stage of the tech evolution. But, with time, the tech world started looking for more efficient methods of testing to scale the businesses easily. And, the no-code test automation tools like PreFlight are those blessings that have really turned the scenario around.
