Also, learn how to develop your app faster to save precious time for the launch phase and plan it using app store optimization best practices.
With release cycles becoming shorter and systems more complex, the need for quicker and more precise testing grows stronger. While there are lots of tutorials for unit testing, integration testing is often overlooked or confused with the former.
That’s why I start this article by explaining what integration testing is and why it’s indispensable. Also, I share recommendations from our solution development team to CTOs that work or intend to work with Java and are looking for best practices to solve the integration testing challenges and perfect their product.
At this point, you might ask, “Why is the CEO writing an article about testing?” The answer is simple—I began as a software engineer and IT consultant, having developed and supported software applications for business process automation. As our team has been working together for years, we have a strong bond that enhances our communication, so everyone from the CEO to the CTO to a developer is on the same page.
In a company like ours, it’s essential not to micromanage but get involved personally and pay attention to every project and every client. To me, that matters.
In unit testing, you check the code bit by bit, each set of modules separately. In integration testing, a type of functional testing, you check if these units integrate and perform together just as you need them. It’s like hiring a team one by one and, during each trial period making sure that, for instance, this Java developer has sufficient hard skills, gets along with the others, and shares the team spirit.
Besides, your Java developer will need to fit in the larger corporate context and beyond: communicate cross-team and, possibly, with clients or other parties. You also need to test that combination for your software and third-party apps or plugins.
The benefits integration testing secures for your software include the following:
I will leave the intricacies to our QAs and provide simple and general recommendations to help your team tweak the integration routine.
