5 Essential Types of Quality Assurance Testing


Even the most talented group of programmers and engineers need a second pair of eyes on a product. As software scales or changes, the chances for harmful bugs or bad data migration grow. Quality assurance testing not only finds existing errors but can also help to prevent future issues and encourage growth. Within the quality assurance field,  there are a variety of different tests. Here are five types of testing a company should pursue to keep their software functioning at peak capability.

Data Conversion Testing

When a company migrates data to a new software, it becomes vulnerable. Once the transfer of information has begun, digital assets are quite literally hanging in the balance. Any errors could cause massive file corruption or even data loss. That’s why extensive conversion testing to confirm the compatibility between old and new systems is important. These tests also check for functionality in the application and uncover hidden defects. Data conversion testing should be performed before, during, and after the migration process. This minimizes the risk of permanently lost data.

Regression Testing

In order for a software company to grow, the product needs to do the same. In a healthy DevOps environment, new features, functionality updates, and patches don’t always cause concern. But any new addition to a piece of code could possibly cause disruption to an existing integration. In regression testing quality assurance engineers check that the software functionality is the same before and after releasing an update. This gets even easier when you introduce automated regression testing into the mix.

Mobile Testing

Mobile devices are inherently different than traditional computer environments. They have different network performance characteristics, less memory, and smaller screen size. Therefore,  challenges unique to these handhelds aren’t usually covered by general performance testing. Mobile testing should focus on performance and usability in a variety of scenarios, such as during low battery, an incoming phone call, or with multiple applications running.

User Acceptance Testing

In a recent season of the HBO show “Silicon Valley” a hapless but gifted startup called Pied Pieper builds a file storage platform with technology that revolutionizes compression and data accessibility. They release the application early after their colleagues like it, only to discover the general public doesn’t understand how to use it. Humorous chaos ensues, but this scenario represents the true importance of user acceptance testing, or UAT. Though a programmer may build an application with a specific intended use, consumers behave in a variety of ways. By engaging in user testing as a form of quality assurance, developers can pick up on unforeseen issues in the performance and user experience.

Software Performance Testing
The designers of an app always want to confirm the specs and abilities of the program. Performance testing helps to define those limits and ensure accuracy by checking for speed, scalability, and stability through a series of experiments. These tests determine how far the program can be pushed. Load testing will identify any potential bottlenecks during heavy user traffic, while stress and spike testing confirm functionality during other scenarios. Overall, performance testing is important to understand the capabilities and limitations of a specific piece of software.

There are multiple times when an application should undergo rigorous testing to ensure the release of the very best product. Testing must occur during production, prior to release, and during important updates as the application scales.
