Automation Testing
• Testing can either be done manually or using an automated testing tool.
• Automated This testing is a procedure done with automated testing tools.
• The limitations of manual testing can be overcome using automated test tools.
• A test must check if a webpage can be opened in Internet Explorer. This can be easily done with manual
testing.
• But to check if the web server can take the load of 1 million users, it is quite impossible to test manually.
• There are software and hardware tools that help the tester conduct load, stress, and regression testing.

Performance Testing
• Web applications should sustain to heavy load.
• To check whether the system meets performance requirements.
Web performance testing should include:
1) Web Load Testing
2) Web Stress Testing
• Test application performance on different internet connection speeds, Access in different browsers,
• In web performance testing web site functionality on different operating systems, and different hardware platforms are checked for software, hardware memory leakage errors, etc.
• In web load testing test if many users are accessing or requesting the same page.
• So, can the system sustain in peak load times?
• The site should handle many simultaneous user requests,
• large input data from users,
• Simultaneous connection to DB,
• heavy load on specific pages etc.
• On the web stress testing is performed to break the site by giving stress and checking how the system reacts to stress and how the system recovers from crashes.
• Stress is generally given on input fields, login, and sign-up areas.
For example: if an app is built for 500 users,
hence for load testing, we check up to 500 users
for stress testing, we check greater than 500.

Mobile Application Testing
• Mobile device testing is the process by which mobile apps are tested for functionality, usability, performance, and much more.
• Testing apps on mobile devices can be done manually or with automation.
• and helps you ensure that the application you’re delivering to users meets all business requirements as well as user expectations.
Types of Mobile Apps
• There are three general categories of mobile applications that you may need to test today:
Native Apps: These are designed specifically for a particular mobile platform (today this typically means either Android or iOS) and are generally downloaded and installed via an app store like Apple’s App Store or Google’s Play Store.
• This includes both pure native apps built on Java/Kotlin for Android or Objective-C/Swift for iOS
Responsive Web Apps are designed to be accessed on a mobile browser.
• Web apps can be either a responsive version of a website or a progressive web app (PWA), which adds additional mobile-friendly features.
Hybrid Apps are designed as a compromise between web apps.
•Hybrid apps can be installed via the app stores just like native apps and may have some native functionality,
• but at least partially rely on operating essentially as web apps wrapped in a native shell.
Top Open Source Tools for Mobile Test Automation
There are popular and open-source tools and frameworks for testing your mobile apps. A few of the most common include:
• Espresso: Android-specific and geared towards developers (recommended by Google).
• XCUITest: iOS specific and geared towards developers (recommended by Apple).
• Appium: Cross-platform and easy to use, with strong community support.
•Calabash: Cross-platform with support for Cucumber, Xamarin-based, and also easy to use.

Following different automation testing tools.
Katalon Studio
What is it?
Katalon Studio is an easy-to-use tool for testing websites, mobile apps, APIs, and even desktop apps.
Key Features:
o It supports testing for websites, APIs, and mobile apps.
o You don’t need to write code to create tests (but you can if you want!).
o Works well with popular tools like Jenkins for Continuous Integration (CI).
o Provides detailed reports and analytics.
How It Works:
You can use Katalon’s recorder to record your actions on a website or mobile app, and then Katalon will play them back during testing
Example:
Recording yourself logging into a website, and then Katalon repeats that to check if the login works properly every time.
--------------------------------------------------------------------------------------------------------------
Appium
What is it?
Appium is an open-source tool that automates testing for mobile apps on both iOS and Android.
Key Features:
o Can test apps for iOS, Android, and even Windows.
o Works with native apps (built specifically for mobile), hybrid apps, and mobile web apps.
o You can write tests in multiple languages like Java, Python, and JavaScript.
How It Works:
Appium uses drivers to interact with mobile apps, similar to how Selenium works with web browsers. You write tests that control the app like a user would.
Example:
Automating the process of opening an app, entering login credentials, and verifying that the login works correctly on both Android and iOS devices.
---------------------------------------------------------------------------------------------------------------
TestComplete
What is it?
TestComplete is a tool that helps automate the testing of websites, mobile apps, and desktop applications.
Key Features:
o Allows both code-based and scriptless test creation (you can just click and record).
o Works with many languages like Python, JavaScript, and VBScript.
o Provides strong object recognition to interact with elements on the screen.
o Can run tests in parallel to save time.
How It Works:
You can either record actions (like clicking buttons) or write code that mimics user interactions, and TestComplete will repeat those actions in the tests.
Example:
Using TestComplete to test whether a button on a desktop application is working properly every time the app is launched.
