Developing a mobile website today is definitely a tough task. With the abundance of devices and screen sizes available, you need to ensure that it is responsive and adaptive. Even if you take the mobile-first approach to design and developing your website, testing it thoroughly across different screen resolutions is more crucial.
As you can see, website traffic from mobile devices is more than 50% now and is going to scale up in the future. The need for businesses to get equipped with mobile-optimized websites is very clear.
This detailed mobile testing guide will help you scale up your mobile testing process.
Mobile Testing is the process of validating a mobile application (Android or iOS) for usability, functionality, and performance. Mobile testing enables organizations to verify if their mobile applications work as intended and meet end-users needs using manual testing or automation testing tools and techniques.
When testing mobile apps, teams must ensure that they perform flawlessly across numerous device configurations. This involves testing the app across multiple screen resolutions, operating system versions, and network bandwidths.
Let us understand the difference between web, native and hybrid apps. The three broad categories of mobile applications available today are:
There are two primary ways to test native mobile apps on LambdaTest: manually & through automation.
Here are the step-by-step instructions to perform manual mobile app testing on LambdaTest:
Here are a few features that will help you navigate your testing goals:
Mobile app testing is a crucial aspect of app development, ensuring that your application functions as intended across various devices & operating systems. LambdaTest provides a robust platform for automating these tests, offering the ability to perform app test automation on a real device cloud. This enables you to validate your app's performance on real-world devices, improving the accuracy & reliability of your test results.
Leveraging renowned testing frameworks such as Appium, Espresso, & XCUITest, LambdaTest streamlines the testing process & helps expedite your development cycles. Here are the steps to test mobile apps via automation.
Step 1: Upload Your Application
The first step in automated mobile app testing with LambdaTest involves uploading your application to the platform. This is where you provide the application under test, which can be an Android app (.apk file) or an iOS app (.ipa file). By uploading your app directly to LambdaTest, you're ensuring it's available for testing across a multitude of real devices on the cloud. This process is equally applicable whether you're using Appium, Espresso, or XCUITest for your testing framework.
Step 2: Write Your Automation Script
Once your application is uploaded, the next step is to write your automation script. This is a crucial step where you define the interactions, assertions, & validations that constitute your test. Depending on your chosen framework - Appium, Espresso, or XCUITest, you'll write your scripts using the syntax & conventions of the respective framework. While the syntax may vary, the goal remains the same: to automate the interactions with your app that you want to test, mimicking user behavior & validating the application's responses.
Step 3: Execute Your Test Case
After your automation script is ready, the next step is to execute your test case. This involves running your written scripts against the uploaded application on LambdaTest's real device cloud. You'll choose the specific devices & configurations you want your app to be tested on, & then execute the test. This step is the same regardless of whether you're using Appium, Espresso, or XCUITest. The test execution will automate the predefined actions, capturing the results for further analysis.
Step 4: View Test Execution
The final step in the automated testing process is viewing & interpreting the results of your test execution. LambdaTest provides a detailed report of your test execution, including logs, screenshots, & video recordings. These artifacts offer invaluable insights into how your app performed during the tests, helping you identify any issues or areas for improvement. Just like the previous steps, this phase is consistent across all testing frameworks - Appium, Espresso, or XCUITest, making LambdaTest a versatile tool for your automated testing needs.
Although the steps outlined above are the same for Appium, Espresso, & XCUITest, the command & code will differ depending on the Framework, OS, & other factors. Depending on the framework, you can follow the links below for a detailed step-by-step guide.
Similar to mobile apps, web apps can also be tested manually & through automation on LambdaTest.
Here are the step-by-step instructions to perform manual web app testing on LambdaTest:
Here are a few features that will help you navigate your testing goals:
In addition to native app testing, LambdaTest supports automation testing on mobile browsers via the Appium framework, providing a comprehensive testing solution for both your app & web-based interfaces.
1. Setting Up the Environment
The first step is to set up the testing environment. This includes installing the required libraries and drivers for the selected automation testing framework. In Selenium, for example, you would need to install Selenium WebDriver & the corresponding browser drivers. Likewise, you must install Cypress using npm & configure your project.
2. Writing Test Scripts
Once the environment is set up you write your test scripts in the language supported that is supported by the chosen framework. These scripts will include instructions for the browser to follow, such as opening a webpage, clicking buttons, filling out forms, and more. The specific syntax & methods would be determined by the framework you are using.
3. Running the Test Scripts Locally
Before running tests on LambdaTest its a good idea to run them locally to ensure they're working properly. If any errors or failures occur, they can be debugged & fixed at this stage.
4. Configurations with LambdaTest
The next step is to integrate with LambdaTest. This usually entails configuring your test scripts to connect to LambdaTest's cloud Selenium Grid. You must enter your LambdaTest username & access key, which can be found in your LambdaTest profile.
5. Executing Tests on LambdaTest
After successfully integrating with LambdaTest, you can run your tests. Your tests will be run on LambdaTest's cloud based Selenium Grid, allowing you to test your web application across multiple browsers, operating systems & device combinations in parallel.
6. Analyzing Test Results
LambdaTest generates a detailed report of your test execution, complete with logs, screenshots & video recordings. You can use these reports to understand better how your web application behaves in various scenarios & configurations.
Note that the exact steps & specifics may vary slightly based on the testing framework you are using. You may need to refer to the specific documentation below for the exact setup and script-writing procedures.

Let's take a closer look at each of these features and how they contribute to making LambdaTest THE tool for mobile testing.
LambdaTest lets you perform Mobile testing on Real Device Cloud, where you can skip the requirement of an internal device library and bring down operational costs. When you perform real device cloud testing, you can make use of network logs, device logs, app logs, videos, and screenshots to debug your app. All you need to do is upload the .abb, .apk or .ipa files to test your apps. You can also install production apps when you download them directly from the Play Store or App Store.
Android Emulators and Simulators help you run the operating system on your desktop. It gives you the same experience of working on your mobile but digitally. mobile application testing using emulators and simulators makes testing a breeze for QA teams. App emulators let you execute a program on a device without actually installing it. Simulators, on the other hand, work with native applications. Therefore, knowing the difference between emulator and simulator is important before performing mobile application testing using emulators and simulators. Emulators and Simulators are not as accurate as real devices since they run in different environments and it does not have the physical properties of a real device making it more economical. When you register for LambdaTest, you get free live real-time testing sessions.
LambdaTest provides comprehensive support for various testing frameworks including Appium, XCUITest, and Espresso. These frameworks allow you to write automation scripts for your mobile app testing, enhancing the speed and efficiency of your testing process. Regardless of the framework you choose, LambdaTest ensures seamless integration and execution of your test scripts on their platform.
Android Studio can use a large amount of memory, slowing down the system. If you have a lower amount of primary memory, like 4GB or 6GB, it becomes difficult or impossible to efficiently perform mobile app testing on different emulators and simulators.
LambdaTest eliminates the need to set up your mobile app testing environment. Its cloud-based service allows you to test with emulators and simulators from anywhere, using a browser and a stable internet connection. The robust infrastructure at LambdaTest's end takes care of everything else.

LambdaTest allows you to test your mobile apps that are hosted locally or privately. This means you can test your app in a secure environment before it is publicly available. This feature is beneficial when you're still in the development phase and need to run tests on an app version that's not yet deployed. By testing your locally hosted or privately hosted apps, you can ensure your app is functioning correctly before making it live, reducing the chances of post-deployment bugs. There are two ways in which you can establish a local connection, Command Line Interface and LambdaTest Underpass.
LambdaTest offers flexibility in how you upload your apps for testing. You can upload apps directly from your local machine or import them from various public cloud links. This feature supports both .apk files for Android apps and .ipa files for iOS apps. The process of uploading apps is straightforward and fast, enabling you to start your testing quickly.
LambdaTest offers integrated debugging tools to make your testing process more efficient. For manual testing, LambdaTest provides DevTools where you can inspect elements, view console logs and more. For automated testing, you can access test execution logs that provide detailed information about each test run. These features make it easier to identify, diagnose and fix issues in your app.
Another critical difference between LambdaTest and Android Studio-type emulators is the ease of access to geolocation testing. LambdaTest streamlines the testing of mobile applications by allowing testers to select the geolocation services embedded within their platform. In addition, users can choose any country from a dropdown menu while running an emulator so they can perform manual testing in that country.
LambdaTest's mobile app testing module can help you localize your application in multiple regions. This can include regional languages, local time, displaying regional currency, etc. With the GPS Geolocation feature you can test from a pin point location to test your webapp for your business needs.
LambdaTest provides a built-in feature for capturing screenshots during your testing session. This functionality is especially useful for documenting issues and sharing them with your team. By simply clicking the Bug icon, a screenshot is captured, which you can then download or annotate using the built-in image editor to highlight any issues or tasks. You can then mark the screenshot as a bug, add details about the issue, and create a ticket, effectively integrating bug tracking into your testing process.
LambdaTest offers the feature to record video of your test sessions, which can be extremely helpful for understanding the sequence of actions that led to a bug, or for demonstrating functionality. You can start and stop the recording of a test session with a simple click of the Video recorder icon in the left toolbar. This makes it easy to document your test process and share it with team members or stakeholders who might not have been present during the actual testing.
LambdaTest's integrated DevTools allow for live debugging during your testing process. You can launch a web app within a mobile browser and perform live debugging with ease, helping you understand the behavior of your application in real time. To access the DevTools, you simply click on the DevTools icon, making this a very straightforward process. This feature can be invaluable for developers looking to fix bugs or understand the inner workings of their web applications.
LambdaTest provides various device controls that allow you to manipulate the testing environment to match real-world user scenarios closely.

These controls help to ensure that your application behaves as expected under different conditions and settings, thereby improving the quality of your testing.
During testing, it's possible to set the idle time out. This is the maximum time a test session can stay idle. If a test session remains inactive for a period exceeding this set idle timeout, it is automatically stopped. This feature ensures that test resources are efficiently utilized and not wasted on inactive sessions.
LambdaTest allows you to install another app during a running test session. This feature can be useful when testing applications that interact with other apps or rely on them for certain features. You can thus test your application in a more realistic environment that closely mirrors the actual user experience.
There may be times during testing when you need to stop or "kill" the application you're testing. LambdaTest gives you the ability to do this, which can be beneficial in scenarios where you're testing how your app behaves when it's stopped unexpectedly or when you want to restart your application as part of your testing process.
Just as you can install additional apps during a running test session, LambdaTest also allows you to uninstall the application you're testing. This feature can be useful in scenarios where you're testing how your app behaves upon reinstallation or when you want to ensure that your app doesn't leave any residual data after uninstallation.

Here are the different types of mobile application tests that are required to perform before releasing the product to the end user.
Installation testing checks the procedures for installing a software system and ensures that the system functions appropriately once installed. The installation process is an important first impression, so the app should be easy to install and free of glitches. If the app takes longer than expected to install or if there are installation issues, the customer will likely seek out an alternative.
Thus, it is crucial to have installation testing as one of the mobile app testing processes before every version release. The key test scenarios that should be covered in installation testing of the mobile apps are:
Functional testing of mobile apps is designed to ensure that every functional aspect of an app works according to the defined business requirements. It is usually performed by individuals involved in testing mobile apps. Users will uninstall an app if it does not function as intended. Functional testing is, therefore, a critical type of software testing.
Usability testing is crucial for any mobile app because it ensures that it meets the criteria for ease of use and user experience. For example, providing an intuitive app design in the form of layout, buttons, navigation options, and color choices can impact user experience.
Usability testing is one of the challenges in mobile application testing that must be carried out before release. It involves refining the app based on user feedback and normal usage patterns. Thus, it is best to involve real users during usability testing to ensure that the app passes this test.
Compatibility testing is a form of non-functional mobile app testing that ensures a mobile app’s functionality across various operating systems, applications, devices, internal hardware specifications, and network conditions.
Before launching an app, compatibility testing is performed to ensure good operability across different devices, operating systems, and browser versions. Software development teams work toward a bug-free, user-friendly mobile application that follows industry-standard software guidelines.
To ensure that its app meets customers' needs around the globe, a company should localize it for different regions. Localization testing is key to ensuring that an app can be used in a variety of languages and contains accurate currency conversions, and adheres to local legislative standards.
Localization testing ensures that software behaves as expected, is accurate, and can be localized for different cities or countries. It can range from testing a program's behavior in a single city to simulating how it will respond throughout an entire country.
Interruption testing is one of the mobile app testing types that should be performed. In reality, people switch between apps for various reasons, such as making a call, sending a message, receiving notifications in an ad-hoc manner, etc. All these interruptions shouldn't negatively impact the mobile app's performance or functional aspects; this is where interruption testing comes into play.
Automating the interruption test scenarios such as manually switching between the apps, remaining in other apps for some time, and then switching back to the mobile app under testing, finding, and sharing the current location (As it involves the usage of a sensor), making a call, sending messages, pressing the lock button or volume up/down button, etc. would increase the productivity of the development and testing process.
When a program fails to return the memory it has acquired for temporary usage, it causes a memory leak. This can cause an app’s available memory to run out, causing the app to become unusable. Because code errors cause memory leaks, every app should be checked for this problem.
Memory leak testing is a process that can be performed on an app running on multiple devices with varying memory capacities. Testers examine each device's performance and tune the program to work well in each configuration.
Mobile app users have high expectations of how quickly an app should respond to their actions. The speed of an app's response depends on its code, the device's hardware, and the OS. Users may become frustrated and uninstall if an app does not respond in 2 to 3 seconds.
Developers and testers must perform performance tests to discover bottlenecks in your mobile app. Key aspects of a mobile app performance test strategy include the following:
The threat of security breaches is critical to any software application. When a breach is identified in an app, especially in a mission-critical app or app involving financial transactions, security threats become one of the tops searched keywords on the internet.
Mobile application security testing evaluates an app's security from a malicious attacker's perspective. Effective security testing begins with a thorough understanding of the app's business purpose and data handling capabilities.
Here are several reasons to justify the importance of mobile app security testing:
Application upgrade testing is one of the most crucial steps in the mobile app testing process. It ensures that the app doesn't crash when its version number has been upgraded, as mismatched numbers can cause glitches in its code. In addition to testing the installation process against the test scenarios, ensure to test the following aspects:
LambdaTest’s mobile test automation platform lets you automate the testing of mobile apps using real devices in the cloud. And because LambdaTest offers both manual and automated app testing, you can conduct your tests on thousands of real devices for mobile app testing.
Mobile app testing continues to grow in popularity among developers and software testers in the digital world.
