What is Manual Testing? (Simple Definition with Mobile Example)
Manual Testing is the most fundamental approach in the Software Testing Life Cycle (STLC). It is the process of manually testing software applications without the use of automation tools. The tester acts as the end-user and validates whether the software behaves as expected. Despite the growth of automation testing, manual testing remains essential because it helps in identifying usability issues, visual inconsistencies, and unexpected behavior that automation tools may miss.
In this article, we’ll cover the basics of manual testing, different types of manual testing, and examples to understand how it works in real-life projects.
Basics of Manual Testing
Manual Testing focuses on ensuring that the application is functioning correctly based on the given requirements. Here are the core fundamentals:
1. No Automation Tools Used
Testers execute test cases manually, step by step.
Tools like JIRA, Bugzilla, and Trello are used for tracking defects, but execution is done without code/scripts.
2. End-User Perspective
The tester plays the role of the actual user.
Validates both functionality and user experience.
3. Test Documentation
Includes Test Plan, Test Cases, Test Scenarios, and Bug Reports.
Example of a simple test case format:
4. Validation and Verification
Verification: Making sure the product is constructed appropriately (in accordance with specifications).
Validation: Making sure the appropriate product is created for the final consumer.
Manual Testing Types
Depending on the requirements of the project, manual testing uses a variety of testing techniques. The most typical kinds are listed below:
1. Unit Testing
Performed individual components or modules.
Developers usually do it, but manual testers may validate test data.
2. Integration Testing
ensures to work together two or more units.
Example: Testing that the user dashboard and login page work together.
3. System Testing
validates the application as a whole.
An e-commerce app’s overall testing, from login to checkout, is an example.
4. Smoke Testing
Build Verification Testing be another word on it.
A quick check to make sure the fundamental features are operational.
For example, checking if an app installs correctly and opens without crashing.
5. Sanity Testing
narrow and targeted testing after small changes.

Top Manual Mobile Testing Interview Questions with Sample Answers
Below are the most frequently asked manual mobile testing interview questions, explained in simple, beginner-friendly language.
1. What is Mobile Application Testing?
Answer:
Mobile app testing is the process of verifying that a mobile application works correctly across different devices, operating systems, and network conditions before it reaches users.
It covers functional and non-functional aspects of the app, including usability, performance, security, and compatibility. A well-tested app works the same way on a budget Android device with a slow connection as it does on the latest iPhone on 5G.
2. Difference Between Mobile Testing and Web Testing
Web and mobile applications are two distinct types of software that serve different purposes and have other characteristics. This section will discuss the main differences between web and mobile applications.
Definition
Web applications are software programs designed to access and use a web browser. They are usually hosted on web servers and built using web technologies such HTML, CSS, and JavaScript. Mobile applications, on the other hand, are software programs designed especially to be installed and used on mobile devices, including tablets and smartphones. They are built using specific mobile application development frameworks and installed on the device.
User Interface
UI, or the user interface, is one of the most significant differences between web and mobile applications. Web applications are designed to be used on larger screens, such as desktops or laptops, and therefore have a more extensive UI. On the other hand, mobile applications are designed to be used on smaller screens and have a more focused and simplified UI optimized for mobile devices.
Development Process
The development process for web and mobile applications is also different. Web technologies, which are widely used and understood, can be used to design online apps, making the process more accessible and quicker. On the other hand, mobile application development requires specific knowledge and skills, which can make it more challenging and time-consuming.
Performance
The performance of web and mobile applications is also differ. The performance of web applications can be an affected by relying on an internet connection to access resources and data. Mobile applications, on the other hand, are faster and more responsive since they are installed on the device itself and have faster access to resources and data.
Functionality
The functionality of mobile and web applications is also differ. Mobile applications are made to be more interactive to provide users more functionality, while web applications are usually used for online services, e-commerce, and information dissemination. For example, web applications cannot utilize a device’s camera or GPS, while mobile applications can.
accessibility
Web applications are widely available and anyone with a web browser and an internet connection can access them. On the other hand, mobile applications require installation on a specific device, limiting their accessibility.
3. What types of mobile apps are there?
Native apps
Native apps are tailored specifically for each mobile platform, whether it’s iOS or Android. So, when you download a native app from the App Store or Google Play, you get a customized experience optimized exclusively for your device.
Cross-platform apps
Cross-platform apps can adapt and run on multiple operating systems with a single codebase. This means that developers can write the code only once and deploy the app on both iOS and Android, thus streamlining the development process. Many cross-platform app development companies specialize in creating efficient and scalable solutions, helping businesses reach a wider audience without the need for separate codebases for each platform.
Web apps
Web apps run on web browsers and are accessed over the Internet. They offer users a wide range of functionalities, from simple tools to complex services, without the need for installation or downloads. These capabilities open up numerous web application ideas for developers and businesses alike.
Hybrid apps
Hybrid apps include elements of native and web applications. While some people use the terms “cross-platform apps” and “hybrid apps” synonymously, it’s not correct as they are different types of apps.
4. What is an Emulator and Simulator?
| The simulator-based testing | The emulator-based testing |
| Simulator’s objective is to simulate the internal state of an object as close as possible to the internal state of an object. | The emulator aims at emulating or mimicking as close as possible the outer behavior of an object |
| Simulators are preferable whenever the testing team needs to test the mobile’s internal behavior, like its internal hardware, firmware, and so forth. | Emulators are preferable whenever the testing team needs to test the mobile’s external behavior, like calculating, making transactions, and so forth. |
| Simulators are written in high-level languages. | Emulators are written in machine-level assembly languages. |
| The simulators can be difficult in terms of debugging purposes. | Emulators are more suitable when it comes to debugging purpose |
| A simulator is just a partial re-implementation of the original software. | Often an emulator comes as a complete re-implementation of the original software. |
5. What is APK and IPA?
APK:
APK stands for Android Package Kit. It is a file extension used by the Android operating system, made by Google and used in the mobile application system. This file type is used to send applications to your phone or home screen.
The APK file format was made up of the original developer. It was created as an alternative to the JAD file format, developed by the Japanese company Jaiku.
An APK is a compressed archive of all the resources needed by an application, including their source code and manifest files. The primary purpose of an APK is to allow easy distribution of applications over the Internet by making it small enough to download and install on any device running Android quickly.
After you have downloaded an APK, you can install it onto your phone and use it like you would like any other app on your phone.
IPA:
An IPA file is an iOS app. If you have a Mac, you can use Xcode to open the file, which will install the app on your iOS Simulator — typically used for testing apps before they are distributed. An IPA file is an archive file like a ZIP or RAR that allows you to install applications on your iPhone or iPad. You can download them from the App Store or iTunes and upload them to your phone or tablet.
Apple’s iPhone, iPad, and iPod Touch devices use the IPA file format. It contains all the information needed to run the app on the device and is typically installed using iTunes or Apple Configurator. IPA files are downloaded from the App Store and stored in a user’s iTunes library, where they can be synced to an iOS device.
An IPA file can only be installed using iTunes or Apple Configurator on a Mac computer. To install an IPA file on an iPad or iPhone with a Windows computer, you’ll need to use Cydia Impactor (for Windows) or Xcode 7 (for Mac).
