When it comes to web apps and games, quality assurance (QA) is the secret ingredient that brings joy to users’ experiences. QA teams work passionately to uncover bugs, boost performance and optimize functionality.
Let’s take a closer look at some examples of how QA makes web apps and games shine.
Quality Assurance for Web Apps
There are mainly six key dimensions for web app testing: functionality, usability, compatibility, performance, web UI and security.
In terms of functionality testing, QA experts put each web app through its paces on different browsers and operating systems. They ensure that the app looks great and works seamlessly on Chrome, Firefox, Safari, Edge and across Windows, macOS and Linux. No matter where the users are, they will enjoy a smooth and consistent experience due to functionality testing.
The web app should be a breeze to use. For this purpose QA testers immerse themselves in the app, exploring it from a user’s perspective. They scrutinize navigation, responsiveness and overall experience, providing valuable insights to make any app intuitive and delightful to use.
We all know that waiting is no fun. Hence QA teams rigorously test the speed, scalability and stability of any web app under different loads and network conditions. They unearth any performance bottlenecks, ensuring that the app loads fast and performs like a superstar.
An important test that the QA engineers perform is the functional testing – that is make sure that all features of a web application work correctly and without any problems. Functional testing for a web application may involve checking that all links work, testing cookies, investigating forms on all web pages, assessing database security and verifying CSS or HTML. It is also important for developers and testers to make sure that test cases include important boundary conditions. In addition, there should be an error message for any invalid input.
There are several critical components to a web app, including the web server interface, database server interface and application server interface. Web UI testing is an important way to validate that all components of the web app are working well together. Testers should use this testing method to determine whether the interaction between the various servers is carried out effectively.
Last but not least, the absolutely necessary security testing: the users’ security is top priority for any QA engineer. For this, QA professionals conduct thorough security assessments to keep web apps safe. They validate data transmission, authenticate users securely and fortify apps against common threats like cross-site scripting and SQL injection.
Quality Assurance for Games
Similar with web apps, games have the four dimensions of testing, but top these there are four more: the game-balance testing, localization testing, load testing and the multiplayer testing.
The game balance testing gives the green light for the exclamation “Let the fun flow smoothly!” Precisely, QA testers carefully evaluate each game’s difficulty levels, progression and character abilities. Their valuable feedback ensures that the game is fair and engaging, providing enjoyment for players of all skill levels.
Games speak a universal language and thus QA professionals verify translations, check text formatting and ensure cultural sensitivity, so that the game will resonate with players worldwide – this is the localization testing.
The type of testing that prevents lags to spoil a game is the performance and load testing. At this stage QA teams push any game to its limits, checking frame rates, loading times and server stability. The objective is to guarantee a smooth and immersive gaming experience for players, where lag is nothing but a distant memory.
Last but not least, any game is tested for multiplayer features. During this ultimate test they evaluate network connectivity, synchronization, matchmaking and the overall multiplayer experience. Lag and unfair advantages are swiftly shown the door.
