Every Android app lives or dies by how well it performs in the real world. Users don’t care how clever your architecture is if the app lags, crashes, or burns through battery. That’s where android app performance testing comes into play. Tracking the right metrics isn’t just nice-to-have — it’s essential to deliver experiences people stick with and recommend. Performance isn’t just technical data. It shapes user perception, retention, session length, and ultimately the success of your product. But what should you actually measure? Let’s break down the key performance metrics every Android team should be watching 1. App Launch Time When a user taps your app icon, they expect it to start instantly. Launch time measures how long it takes from that tap to when the first meaningful content is visible. Slow startup times increase abandonment and give a lousy first impression. Industry guidance even suggests aiming for cold starts under 500 ms when possible. This metric is both technical and ...

  Introduction In software testing, teams need clarity on both  what  to test and  how  to test it. This is where the distinction between  test scenarios  and  test cases  becomes important. While the two are closely related, they operate at different levels of detail. This distinction becomes even more critical when  testing real user journeys across devices , regions, and network conditions. Let's learn them in detail in this blog post. What Is a Test Scenario? A test scenario is a high-level description of a feature, workflow, or user journey that needs to be tested. It defines the scope of testing by answering a simple question:  what needs validation? Test scenarios  focus on end-to-end behaviour rather than individual steps. They are usually derived from requirements, user stories, or business flows and help teams ensure that all important paths through the application are covered. Examples of test scenarios in BFSI App C...

  Mobile applications are now a primary channel for regulated industries such as banking, healthcare, telecom, and government services. These apps handle sensitive user data, support critical transactions, and are subject to strict compliance requirements. As a result, testing infrastructure is no longer a purely technical concern. It is part of the organization’s risk and compliance boundary. Device farms play a central role in  mobile app testing  by providing access to real devices at scale. However, not all device farm models are suitable for regulated environments. The choice between public and private device farms directly affects data exposure, audit readiness, and overall testing reliability. Understanding how these models differ helps regulated teams make informed decisions about where and how they test their mobile applications. Why regulated industries need real device testing for mobile apps Emulators and simulators are useful during early development, but the...

  Robotic process automation (RPA) is the technology that streamlines the building, deployment, and management of software bots emulating human actions and interacting with digital systems. These software bots can navigate systems, identify and extract data, and perform other actions much faster and consistently. RPA is used to automate back-office transactions involving repetitive tasks, analysis and reporting, bulk emails and extractions, data format conversions, ERP transactions, process lists and file storage, etc. Prominent organizations around the world look for automating their business processes using configurable software bots, which is made possible with RPA. This technology runs hand in hand with inbuilt artificial intelligence. The RPA automates large workflows by reducing repetition and redundancy by eliminating human interventions. The ultimate goal is to reduce cost and time to market, improve efficiency, reduce errors, and let resources focus on other critical busin...

  Modern software applications are expected to work seamlessly across a wide variety of devices, operating systems, and browsers. Users access applications from smartphones, tablets, laptops, and desktops using different browsers and network conditions. This diversity creates significant challenges for software testing teams.   Mobile application testing   and cross-browser testing play a vital role in addressing these challenges and ensuring consistent, high-quality user experiences. This article explores the most common software testing challenges and explains how mobile application testing and cross-browser testing help overcome them. Device and Platform Fragmentation One of the most persistent challenges in software testing is device and platform fragmentation. Mobile users rely on hundreds of device models with varying screen sizes, hardware capabilities, and operating system versions. Web users face similar fragmentation across desktops, laptops, and tablets. Mobile...
