The mobile app test pipeline is dependent on performance testing. You will be able track and predict changes in performance for spikes in connection (LTE, 4G, or LTE), user location change, traffic load increases, and other factors.
Mobile apps require that you test your product on various devices in order to determine if android performance testing is affected by changes in screen size.
This post will explain how to perform mobile app testing. It also includes tips and tricks that can help improve the tester's work flow.
A mobile application, by definition, is software that can be run on a mobile device (either a smartphone or tablet). They can be either web-based or standalone. Due to software limitations, one-screen constraints and poor comprehension, mobile apps do not allow multitasking.
Although porting an existing PC app to a mobile-based project is possible, it's not the best way to go. Developers tend to create mobile software from scratch in order to take advantage of the unique features of mobile devices.
To assess the app's performance in simulated environments (or multiple), mobile app testing is done. This allows us to predict the user's experience following a public release.
Performance assessment is usually done by testers. They test the system's response on a variety of devices. The app's performance at peak traffic loads is also checked.
These are the stages of mobile app testing:
It is tempting to ignore mobile app performance testing when development teams are under time pressure. This is not a good idea. Otherwise, the tester will ignore any bugs that aren't obvious and distributers would likely reject the app (App Store for iOS and Google Play Market for Android).
The list of goals that performance test can help testers achieve is extensive. It includes:
For newly-funded startups, it can be difficult to create a strategy. Good news: The app performance testing approach works for all industries and scales.
A project manager must develop a strategy in order to execute successful performance testing. The following steps are typical for a step-by–step performance testing plan.
Performance testing is only as good as the goals it aims to achieve. It is important to set objectives that are relevant to the business goals of each case. The top priority for a tester would be to evaluate the functions of an app that are critical for lead generation, such as the cart feature for ecommerce stores and the registration and contact forms.
This stage is where the testing team learns the most about the product's architecture, including its business and data levels.
You can determine if your execution was successful or not by setting benchmarks. The following KPIs can be used to test mobile apps:
A beginner tester can fall into the trap of trying to test all features at once, without having selected cases. It's better to describe multiple scenarios that are critical for reliable app performance.
Once you are confident that critical features are working properly, it is time to dig deeper and test lesser-important scenarios.
It is essential to test the app in a testing environment. This will allow you to assess the user experience and how it compares to what people will have after it goes live. System emulators are a common tool used by QA specialists to accelerate the testing process.
These tools are able to simulate the operating system's basic parameters and give testers a feel for the interface. It's best to test the performance of features that are dependent on camera permission, GPS, or other device-specific functions.
The company's overall development plan should include testing. Agile testing requires that the tester is able to use continuous integration principles. Waterfall is a preferred method of testing, so testers should be able to align their workflow. This includes regular bug reports and regression test.
The same testing and development methodology allows all parties to be on the same page about the project. This improves communication and speeds up the decision-making process.
Mobile devices can be connected to the internet via third-party carriers. This means that latency and bandwidth can differ. A QA specialist can optimize the app's performance while focusing on the differences between carriers to improve the user experience.
Any test can be gathered. These steps are necessary to set up an environment for performance testing an app or mobile website.
Testing mobile apps can be more difficult and tedious than testing PC software. Testers can be frustrated by the large number of devices available, their mobility, and the need to use specific features.
Here are some of the biggest challenges in performance testing mobile apps.
Two approaches can be used by testers to evaluate the performance of mobile applications. First, test the product's server-side performance. The development team can then check the logic and readiness of the app. The second is to evaluate the performance on a device, either physical or emulated. A tester can see the product through the eyes of a user.
These are the top tools to test server-side performance.
JMeter is one of the most popular tools for mobile performance testing. It is an open-source tool that allows for plugin support and has an easy-to use interface. It offers a variety of testing options, including multiple load generators or controllers.
It can also be used to test availability and volume. JMeter provides data visualization tools as well as HTML-rich reporting.
Users are provided with detailed documentation by the development team that helps them to use the tool.
Gatling, an open-source tool to perform performance testing, was created in 2012. It features the following key features:
Gatling's interface is easy and simple - it's an ideal fit for junior performance testers. However, developers should not mistake a simple interface with a lack of functionality. Gatling allows for up to 600 concurrent users to run tests. Two executables are available for the tool: to run tests and record them.
After testing the server-side performance, the team executes a code test on the physical devices in emulated settings. These tools are useful for such testing.
Sauce Labs is an online platform for testing. It supports 800 browser types, creating a bug-free environment for testers. You can run parallel tests that do not interfere with each other using the tool.
Sauce Labs makes it easy for developers to manage large test volumes and automate mobile tests using very little programming knowledge.
Appium Studio is a tool that allows you to test mobile performance. Appium Studio is widely praised on the internet due to its easy-to-read and write code, a variety of supported tests and a unique XPath.
Appium Studio allows app testers to access device-specific features such as TouchID, barcode scanning and many other.
UI Automator, an open-source tool to test mobile apps' performance, is available. JavaScript-based scripts can be written by testers and executed. UI Automator features an intuitive interface and an integrated Android emulator. The app does not support iOS apps at this time.
Robotium is an automated testing tool that supports both native and mixed Android apps. Developers have enough freedom to create custom systems and functions as well as test scenarios using the framework.
Selendroid is a Selenium framework that allows QA professionals to simultaneously test multiple Android apps and switch between cases. You can run multiple emulators simultaneously with the tool. However, the downside to this tool is that testers must write code using Selenium 2 API.
Testdroid can be used for automated and manual tests. You can record the process of execution and sort through test cases as well as their reports. It is free to use, and it also has its own API.
Drop us a note. We have probably dealt with similar problems in 300 of our previous projects.
Testing mobile app performance is a complex task. A QA specialist must perform a variety of tasks to ensure that the product functions as intended.
These are some of the most popular examples of performance testing:
A team of professionals certified in mobile performance testing can make it efficient. Hire Software Experts offers QA resources for mobile apps in finance, retail and insurance.
