In software development, integration testing is a crucial step where different units of code are combined and tested to make sure that they work seamlessly together.
Without causing any malfunctions, it’s all about making sure that all the gears in the machine work together. There are a few types of integration testing, that serve the specific purpose of producing high-quality software.
Types of Integration Testing
- Incremental testing:It is a process in which multiple modules are combined and tested logically. It allows the testers to check for bugs at an early stage examining the integrated applications carefully.
Based on specific types of testing done, there are different types of incremental testing which are:
- Bottom-up testing:This type of testing begins with the lower-level module in the architecture and moves upwards. This is useful as it is done during the early stage of development which allows for any bugs to be addressed quickly. So, for identifying and solving problems less time will be needed.
- Top-down testing:For the highest module, this type of method is used to begin the testing. It allows you to test the whole system by gradually moving downwards.
As you move from the top to the bottom through the structure of the architecture, you can integrate and test the modules with this approach. Also, it is essential to remember to stick to the same terms rather than restate the same idea many times.
- Sandwich Testing:This is also referred to as the hybrid integration testing which combines both the elements of top-down and bottom-up approaches. By conducting the test in both the downward and upward directions, it is used to test the integration of modules within a system.
Unlike the traditional method that mainly focuses on one direction, sandwich testing starts at the middle layer and moves towards both directions. This allows for the comprehensive evolution of interfaces and control flows within the modules.
The faster and more efficient integration testing can result due to a combination of bottom-up and top-down approaches. This provides advantages from both methods. So, testing and seamless integration of modules with the system can be ensured by this sandwich testing.
The sandwich approach also consists of drawbacks as it consists of using two different methods of integration testing. This may not be suitable for all types of software applications because of its complexity.
- Big Bang testing:In this type of testing, all the modules are put together and then tested as a whole unit. This is not a kind of incremental process as it is usually done for the smaller systems. Once all the modules have been assembled to make a complete system, this testing is performed only after it.
