Top Visual Regression Testing Tools

  At an estimated 1000 + mobile network operators and approximately 4,500 networks globally (at least) , ensuring consistent app performance is a challenge. The global carrier landscape is highly fragmented, with thousands of operators worldwide. Then there are the infinite network strengths that every app must adjust to the varying network strengths of internet connections across the world. A single user of any app transitions through multiple strengths of network connectivity — Wi-Fi, LTE, 3G, 4G — throughout a single day, as they move from place to place, going about their daily routine. Naturally, it is essential for development teams to test mobile apps on different networks and carriers comprehensively. In this article, we’ll discuss the need for doing so and a few best practices for telecom testing that impact app performance, reliability, and usability. Why Is It Necessary to Test Mobile Apps on Different Networks & Carriers? Mobile apps must...

  You work on systems that don’t run in a vacuum. APIs talk across regions. Mobile users hit your endpoints from unstable networks. Microservices depend on each other across layers of infrastructure you might not fully control. One thing is clear: network performance significantly affects how well your software holds up. Maybe you’ve noticed issues that only show up in production—timeouts in a service that passed every functional test, or “slowness” that no amount of backend profiling explains. These are often tied to how your app behaves in real-world conditions, especially on real device testing setups that simulate actual mobile environments. Network performance testing gives you the data to understand how your system performs when the network behaves like the real world for real users: sometimes fast, sometimes congested, and occasionally unpredictable. The best part? This is already on your radar if you’re a senior QA, performance engineer, or Site Reliabili...

  People have become massively dependent on digital devices and it is imperative to have reliable software testing tools. As of April 2024, there were 5.44 billion internet users worldwide , which is 67.1 percent of the global population. More and more users are now becoming aware and to meet their expectations in terms of performance or interface, companies must adapt to new techniques to provide users with the best apps. Cross-browser testing ensures that a website is working optimally on different browsers, it improves overall efficiency, while reducing unnecessary errors and saving time. There are several testing tools in the market. However, it may be challenging to find the best fit for your needs. While Playwright is a powerful testing tool, you must note that it has certain limitations due to which you may want to explore other effective alternatives. This blog will walk you through the basics of Playwright for cross-browser testing . If you are looking for a n...

  With global travel and tourism at an all-time high, customers naturally expect their telecommunication services to work flawlessly, regardless of whether they’re outside the wireless provider’s coverage area. Therefore, roaming isn’t a nice-to-have feature anymore; it’s a must for the everyday mobile experience. During the 2G and 3G eras, roaming charges regularly appeared as separate items on the customers’ phone bills. However, that changed when nationwide and international plans came into play. Roaming testing gained precedence; it shifted from just a pre-deployment formality to a critical strategy for ensuring consistent service and accurate billing for the network provider and its subscribers. In this blog post, we’ll discuss everything you need to know about roaming testing, including its core focus areas, standards and methodologies, and strategies. What is Roaming Testing? It refers to verifying the performance and functionality of a mobile...

The use of mobile apps in every little thing of day-to-day life has led to a rapid pace of mobile app development. With such quick growth, it becomes crucial to deliver high-quality apps. The development teams need to ensure quick release time, which requires mobile app testing cycles to be fast and reliable. Testing application scenarios sequentially can take days or even weeks to complete. This is where parallel test execution improves the efficiency of the testing process. Parallel testing in Appium requires careful configuration to initialize multiple Appium server instances and manage unique device capabilities.. By doing so, you can maintain the vast test coverage by reducing the execution time for your tests. In this article, we will go through a step-by-step guide on how Appium parallel test execution can be done using Java.   What is Parallel Testing in Appium? Parallel testing is the execution of multiple automated tests concurrently, instead of run...
