What is Quality Assurance

The term Quality assurance comprises of two words, Quality and Assurance. Quality refers to the degree of excellence of your product or service and Assurance means a positive declaration intended to give confidence. So to sum up, Quality assurance means the promise to deliver the best version of a product, and providing the best in the case of mobile applications is a continuous process. Getting feedback from the audience after launch, fixing the bugs and maintaining a user-friendly app that users rate well are the ultimate goals of the Quality Assurance teams.

Why is Quality Assurance of your App Important

If you are planning to launch an app just to be out there in a crowd, then you are not doing very well. If your app is not reliable and the services provided are not of superior quality, users will be bound to delete the app and switch to something else, which can decrease your revenues. Here are some statistics of people who think what causes a faulty app and is not worth keeping:

What are components of Quality Assurance

Quality Assurance is a crucial step before launching an app, and should never be underestimated. This consists of various types of tests to be conducted either automatically or manually whichever is in the best interest of the type of business or application. Here are some components of Quality Assurance out of which the most most suitable one is selected by the developers for a thorough analysis of the application from time to time.

●     Load and Performance Testing

How an app performs under the stress of thousands of users at a time and whether it can hold the performance level up to optimum capacity or not, is the cause of performing load and performance tests. These are mostly done automatically in simulated environments.

●     Regression Testing

How the application performs after the upgrades is crucial to determine as most of the time, there is the risk of compromising the functionality. So using automated services by forming a thorough test script at first would lead to smooth and fast testing procedures in the future no matter how many times the upgrades arrive.

●     Exploratory Testing

This is a manual testing procedure where the developers explore the app with an open mind without knowing any specific problem with the app but looking to find one in any areas possible by following a script. The script is a series of well-defined events to be executed in an order to make sure none of the crucial items are left unchecked. 

●     Usability Testing

Testing to see whether the interface gives a beyond satisfactory experience to their users, if there is any flaw with aesthetics, looks or feel. This is also done manually because the subjective perceptions of human beings can not be achieved by automated mechanisms.

●     Unit Testing

Automated test suits designed to verify the code developed for the app is working and functioning individually as expected or not, to inspect the development at a rather micro level. It helps pinpoint the flaw in case it exists, so it could be rectified specifically at that point.

●     Integration Testing

This testing is done manually through emulators to see if the units of code respond to each other and work with other units correctly or faults in their integration exist. If unit testing has satisfactory results, the Quality assurance team moves on to see if the code responds to the corresponding bits as expected or if it is flawed.

●     System testing

A further stage of testing is where the full and final integrated software or application is being tested as a whole to see if it complies with the required specifications. When the nitty-gritty of code is verified then comes the testing of the cohesive interaction inbetween the system to see if it is able to perform the specified functions successfully. 

●     Compatibility Testing

Application is tested to run on several devices with multiple types of Operating systems to eliminate the possibility of failure of processing in different computing environments due to a lack of appropriate hardware or software. It can include testing the push notifications, battery drainage time, device heat up, etc. 

●     GUI Testing

GUI or Graphical User Interface Testing is performed to see if the interface responds to the command as intended by the user or redirects to an irrelevant landing page. In simpler terms, if the graphical items respond to the user in the way he expected them to. If this test is not passed, the customer might think the application is faulty as it is unable to perform his required action on the command.

●     Security Testing

For security testing, the application is run through different security scans to check the vulnerability of the system to external threats like an invasion of the user’s privacy, etc. Basically the application is exposed to a series of simulated attacks to study the output of those attacks and how the application will respond to them.
