As a manager or executive, you know that quality assurance is crucial for your development project. You also know that there are multiple QA requirements your project should meet and a range of test types the project should undergo to qualify for a high-quality product.
Let’s skip through the QA test types that are vital for your project and find when you need to apply each of them.
- Integration Testing
Every app that you use on a regular basis has multiple components inside it. To understand the idea of integration testing, think over all the steps a program makes to let you do some action. Integration testing ensures every component works individually as well as puts all of them together to define how they operate as a whole, or in integration. This type of testing comes before the test of a whole system. While system tests the app’s functioning, there’s a major difference: integration testing is done during the development phase to make sure the pieces fit together.
- System Testing
When you’ve got the full product, functional testing starts. It’s usually done at the late development stages when the app is about to be released. The main idea of such testing is to verify all the software components work well together before they the product hits the market. These tests are run to detect any weaknesses of individual features and problems occurring as different code sections are put together in the full product. Similarly, system testing is used to check the proper functioning of a product across the platforms.
- Feature Testing
Before launching any new features, it’s a must that they pass a rigorous check called feature testing intended to ensure no new feature or new change is going to compromise the app’s quality. Typically, this type of testing is used on the launched app which is added some completely new features or its features are expanded.
- Usability Testing
As the ultimate goal of every project is to make its users happy using it, rigorous usability testing prior to the launch is essential. Usability tests verify that the product meets the requirements and customer expectations. After a usability test you’ll get plenty of customer feedback indicating how successful your project is going to be and what is to be improved in it.
Finally, to test your product in full and efficiently, it’s recommended to build a detailed QA plan which would describe all the test which need to be run throughout the development cycle. You’ll want to include the test types mentioned in this article into your testing plan in the first place.
