Mobile Applications: What is the importance of testing?

When it comes to Mobile Applications, we cannot skip the discussion on the importance of high-quality applications. It is crucial for apps to run smoothly on every operating device or system and that is why we need to test them to check their working. This helps in getting to know the glitches or how the app can be improved. In this blog we are going to throw a light on tools and techniques used for the testing.

Why Mobile App Development Testing is Crucial

  1. Enhancing User Experience:

  • User Satisfaction: Testing provides us with an idea of how the app is running and if the user would face any issue while using it because without any doubt an app that runs smoothly gains a substantial number of users.
  • Performance Consistency: With millions of users, it cannot be guaranteed that all of them are using high-quality devices; some budget-friendly smartphones may be used. Therefore, developers should create an app in a way that ensures it functions without any hindrance on all devices, whether high-quality or lower-quality ones.

  1. Ensuring Functionality:

  • Bug Detection: Testing helps to identify the bugs that can induce issues for the user and helps in rectifying these bugs prior to the app usage by users.
  • Compatibility Checks: With a wide range of devices and operating systems existing, testing helps to check that the app runs well on all platforms and screen sizes.

  1. Meeting Business Goals:

  • Minimizing Costs: Solving issues prior to the launching of an app saves a lot more cost than doing it after launching.
  • Time Efficiency: Prior testing and solving the issues saves time and other resources as well.

Mobile App Testing Tools and Techniques

  1. Automated Testing Tools:

  • Appium: It helps in automated testing for iOS and Android apps and lets you write tests in various programming languages.
  • Selenium: It was made for web applications but can be used for mobile testing through Selenium WebDriver. It can support different websites and browsers and thus helps in cross-platform testing.

  1. Manual Testing:

  • Exploratory Testing: This technique includes completely fresh testing of an app without the predefined test cases to detect unseen and unexpected issues that the app may offer.
  • User Acceptance Testing (UAT): In this, the real users test the app that gives the exact idea of how it will perform and whether it will be liked in the market. In short it gives honest and real feedback.

  1. Performance Testing:

  • Load Testing: Tools like Apache JMeter or LoadRunner involve multiple users interacting with the app at the same time. This helps in getting to know about the app’s capability of dealing with the traffic and potential performance bottlenecks.
  • Stress Testing: It includes pushing the app beyond its normal limit to see its performance in hectic condition. It is vital for knowing the breaking points and testing its reliability under stress.

  1. Compatibility Testing:

  • Device Farms: Services like Browser Stack and Sauce Labs offer cloud-based device farms that let developers perform testing on a broad range of devices and OS versions. This makes sure that the app is consistent in performing in varied environments.
  • Emulators and Simulators: Although these cannot be compared with real device testing, they help in preliminary checking. They replicate various device configurations and operating system versions, allowing developers to spot potential issues early.

  1. Security Testing:

  • Static Analysis: Tools like Veracode or Checkmarks analyze the app’s source code for vulnerabilities. This helps in identifying potential security flaws before they can be exploited.
  • Dynamic Analysis: This involves testing the app in a runtime environment to detect vulnerabilities that may arise during execution. Tools like OWASP ZAP are available for dynamic security testing.

Conclusion

In the scenario of mobile app development, app testing is not merely a choice of preference but a crucial component that decides the fate of an app. If you rigorously test the app and resolve all issues, it will perform well in the market and help you gain a great deal of users. This in turn is also going to add shining stars to the goodwill of your company. Automated and manual testing techniques, leveraging performance and compatibility tools, and incorporating security checks, can assist in making your app a momentous success.
