How to perform integration testing step by step

by Hruska William Best Software Testing Company In Canada

As of today, the market for software testing is valued in billions. Today companies strive to compete and gain an advantage over their competitors. From a software development perspective, this can only happen when software products are not only of the best quality but also exceed customer expectations. The quality of a software product is directly linked with effective software testing strategies. In this article, you will know how to perform integration testing.

Body:

What is integration testing?

It is a testing method where the interface is tested between two software modules. This testing method is performed to identify issues in the interaction between integrated units.

Following are the five steps needed to perform integration testing (top-down method):

1. Develop a well-thought-out test plan: Test plans play a key role in the testing process provided it is kept up-to-date. QA teams must strive to maintain test designs continually and avoid ineffective tests that are not in line with the core objectives of the project.

The testing team must have a detailed integration test plan to avoid confusion and ensure that everyone (who is related to testing activities) is familiar with the testing strategy. When it comes to timelines, approaches, and focus areas, planning documents will serve as go-to resources. The team can navigate through complex system structures if it has a detailed test plan to rely upon. This will in turn save costs and reduce the number of efforts.

2. Testing early can prove to be beneficial: Testing activities should be launched at the earliest in the software development process. Costs associated with fixing and detecting issues will be comparatively less. If QA is introduced alongside development, then the frequency of releases will have a positive impact and a foundation can be laid for accelerated software delivery.

3. Automation can not be ignored: There is a perfect synergy between integration tests and automation. There may be instances, where manual testing is still preferred due to a shortage of talent or limited costs. It is still advised to start small and build up resources and scope over time. If the business demands automation in certain key areas, then investment in it is the only and best option to go for.

4. Different methods of integration testing can be combined: To check if the system modules function properly or not is not what testing is used exclusively for, it is beyond that. There are many external factors that contribute to defining the end-user experience. Just the source code quality such as databases, tools, production ecosystems, servers, etc., doesn’t contribute to the success of the entire testing process. If all of them need to be validated on both high and low-level components, then the approach needs to be reconsidered and thus run tests to simulate your production environment.

Your methodology, engagement model, and project size might evolve and change, but to succeed on a continual basis, practices need to be adopted. Different testing strategies must be implemented in order to get the desired outcome.

5. Focus on the outcome: Even if integration testing is going to be implemented through a well-designed and well-defined strategy, still the work of receiving modules is simulated, and realistic test results are achieved. What this means is if there are any interaction issues in the lower-level modules, you will not know about them.

Conclusion: The above-mentioned five steps define how integration testing is performed. If you are looking for strategic solutions in integration testing that can be of value for your specific projects, then just get connected with a leading software testing services company that is committed to giving you profitable ideas and a workable strategy that perfectly works for your organization.
