After having known about Integration testing in detail, businesses should also know the most important aspect of Steps to Perform Integration Testing.
Before planning to perform integration testing, it is necessary for the teams to prepare a test plan strategy. This helps them to perform testing that is in flow. Simultaneously, the developers have to identify and document test cases and test data. This will help to identify the critical modules that need integration testing on a priority basis and also have an understanding of other modules.
While designing the test cases and test scenarios, it is essential to gather information related to integration test templates. Interfaces have to be reconciled, i.
If there is no indication among these interfaces, then these need to be examined and fixed before moving further for integration testing. In order to process the integration testing for each program unit, test conditions should be prepared. Once the conditions are listed, these have to be documented, so that they can be used while performing integration tests. When the test scripts and test conditions are prepared, choose an automation testing tool for integration testing.
Execute the test cases and if there are any defects identified, report the defects for re-testing. For the test cases that reported defects, perform re-testing. This step has to be carried until the integration testing is completed and all the conditions are fulfilled.
Protractor: This is an open-source automation framework known as an E2E testing framework. Protractor is preferred for applications that are based on Angular and AngularJS.
This tool helps to provide a scripting free environment and helps to avoid the bugs related to integration testing within the iterative agile development process. It provides many features such as the creation of code-free and reusable stubs and also reduces the risks of any failure. This software testing tool helps to perform integration and unit testing for embedded software.
This tool by Liverpool Data Research Associates LDRA is a tool suite that helps in automating the code analysis for performing integration testing and also helps in verifying the compliance standards, etc. Next Software Engineering Black box testing.

Start Your Coding Journey Now! This approach is practicable only for very small systems. If once an error is found during the integration testing, it is very difficult to localize the error as the error may potentially belong to any of the modules being integrated.
So, debugging errors reported during big bang integration testing are very expensive to fix. Advantages: It is convenient for small systems. Disadvantages: There will be quite a lot of delay because you would have to wait for all the modules to be integrated.
High risk critical modules are not isolated and tested on priority since all modules are tested at once.
Bottom-Up Integration Testing — In bottom-up testing, each module at lower levels is tested with higher modules until all modules are tested. The primary purpose of this integration testing is, each subsystem is to test the interfaces among various modules making up the subsystem. This integration testing uses test drivers to drive and pass appropriate data to the lower level modules.
System integration testing will make sure your new requirements are met. When issues are detected and fixed as early as possible, you can start marketing your software without delay. A provider of software testing solutions can help you save some valuable time by quickly letting you know what you need to fix. Your developers know all about programming software, but they might not know everything there is to know about software testing. When you hire a team of experts to take care of system integration testing, your developers will be free to focus on what they do best.
Do you know the difference between top-down and bottom-up testing? Integration testing experts know of different approaches and processes that will help you make sure that your software is the best it can be, and that no bug or issue is left undiscovered.
