No one likes bugs in their software -- especially when they show up after your software has already gone to market. From simple glitches to major security vulnerabilities, bugs can damage your reputation as a software provider and disrupt the user experience.
Of course, there’s no avoiding bugs entirely, so it’s best to catch them early. By building a quality assurance process into your routine, you’ll reduce the risk of releasing an app or software update that contains errors.
While some companies have internal QA teams, others hire external specialists, who provide a fresh eye and specialized tools to find the flaws in your programs.
Why do you need a software QA service?
Software programs are more complex than ever, and with the pressure to continually release new updates and features, traditional testing strategies just can’t keep up.
While internal user testing is an option for some companies, it won’t replace thorough QA testing. That’s because non-technical employees might be able weigh in on UI or design glitches, but they won’t find problems at the database level.
Quality assurance services, on the other hand, specialize in uncovering bugs, and can put your product through rigorous testing, both manual and automated.
One company, called Ultranauts, specializes in hiring neurodiverse employees on the autism spectrum, due to their skills at pattern recognition and logical reasoning. They uncovered 56% more bugs than their client’s previous testing partner, IBM.
Quality assurance concerns aren’t limited to reputational damage. Errors in a financial services app can lead to serious data breaches or currency rounding attacks. Trading algorithms can make rogue deals that cost companies millions.
When developers are stuck cleaning up software bugs themselves, it can eat up to 75% of their time on the job. Ultimately, you simply may not have enough employees on hand to develop, test, and debug your software before bringing it to market.
That’s where software QA services come in.
How do software QA services perform quality control?
Most QA services fall into one of two categories, manual testing and automated testing, which can be further broken down into specific types of tests.
Manual testing is when a human tester actually sits down at the computer (or mobile device) and uses the software themselves. The main benefit to manual testing is that you can get real-time feedback without having to design an automated test.
The downside to manual testing is that it takes time for an individual to perform the test, and there’s a greater chance of human error or inconsistent behavior.
Automated testing is performed using a test script that can be run repeatedly, either by focusing on a specific aspect of the program, or performing the same actions in different ways to see whether they all get the desired result.
The benefit to automated testing is that you can dive deep and find bugs that a human tester can’t see, while avoid the variables that comes with manual testing.
The downside is that the test script itself may need to be debugged, and you won’t get any feedback on the user experience, such as the colors or other visual elements.
In addition to these two approaches to testing, specific QA services may include:
- Unit testing: testing individual software modules
- Integration testing: making sure the modules interact properly
- Accessibility testing: testing whether the software can be used by people who are deaf, blind, color-blind, or have other disabilities
- Compatibility testing: ensuring the software works on a range of browsers, operating systems, hardware, etc.
- Performance testing: checking the software’s speed, load capacity, etc.
- Security testing: testing for security vulnerabilities
- And more
The type of testing you need will depend on what kind of software you’re developing. A thorough testing routine should ensure that the software can handle the tasks it’s meant to perform, without breaking down when something unexpected happens.
Different software QA services specialize in different types of tests. Ideally, you’ll want to find one that can test your software repeatedly at different stages of development.
Some testing services use a waterfall model, in which testing takes place only after the design period is complete, while others use an agile model, in which development and testing take place concurrently, and the software is constantly in a state of review.
Be sure to choose a company that has experience working in your industry, and can tell you exactly what kind of testing they’ll perform and what tools they’ll use to do it.
Here are some of the best software QA services around:
