What you'll learn

Mocking of API calls for the Mobile App - Request JSON Body, Response JSON Body, Headers
API Dependence: Mobile applications frequently rely on external APIs that may be unreliable or subject to change. The Intercept Plugin allows you to mock API
Enhanced Test Coverage: By dynamically manipulating request and response data, you can test a broader range of conditions without needing backend
Faster Testing Cycles: Mocking APIs eliminates the need for a live server and reduces test execution time

Introduction (Author) and My Role in Advanced QA Engineering5:56
Hi My name is Anil, I am a highly skilled software engineer with expertise in mobile automation using Appium, web automation using Selenium, and API automation using RestAssured. I possess strong proficiency in Python and have extensive experience in API performance testing using the Locust tool. Additionally, I have a deep understanding of tools such as SpringBoot, Gradle, TestNG, Jenkins, HeadSpin, and pCloudy.
My experience in mobile, web, and API automation has enabled me to develop a comprehensive understanding of testing frameworks, test plans, and testing methodologies. I have a proven track record of delivering high-quality software products that are reliable, scalable, and maintainable.
I am committed to staying up-to-date with the latest technologies and tools, and I am always looking for opportunities to expand my skills and knowledge. I am passionate about delivering value to customers through quality software products and am excited to leverage my skills to contribute to the success of any organization that values innovation, collaboration, and continuous improvement.

Common problems faced by the front end automation frameworks2:31
In today’s complex mobile applications, testing can be challenging due to the dependency on live APIs and third-party services. Traditional testing methods often fall short when dealing with inconsistent or unavailable external services. This is where the Appium Intercept Plugin becomes essential. It allows testers to simulate and control API responses, providing a crucial mechanism for robust front-end testing.

Join us for an intensive workshop focusing on leveraging the Appium Intercept Plugin with Mocking support. Learn advanced techniques to manipulate outgoing request URLs, modify request payloads (POST Body), update headers, and customize response headers, bodies, and status codes dynamically. Enhance your testing capabilities by mastering the art of simulating diverse API behaviors for comprehensive QA automation.
Solutions to Overcome this Challenge: Key Features and Strategies1:35
Why is the Intercept Plugin Required? The Appium Intercept Plugin is designed to address several critical issues in automated testing:
Simulating Edge Cases: Testing edge cases or error scenarios often requires specific API responses. With the plugin, you can simulate diverse API behaviors (like timeouts, failures, or unusual data), which helps in validating how your application handles these scenarios.
API Dependence: Mobile applications frequently rely on external APIs that may be unreliable or subject to change. The Intercept Plugin allows you to mock API responses, ensuring that your tests remain stable and consistent regardless of external API availability or behavior.
Enhanced Test Coverage: By dynamically manipulating request and response data, you can test a broader range of conditions without needing multiple backend configurations. This improves the coverage and effectiveness of your tests.
Faster Testing Cycles: Mocking APIs eliminates the need for a live server and reduces test execution time. This leads to faster feedback during development, which is crucial for Agile and continuous integration practices.

Outline1:00
Outline the next steps: install the UI automated driver for Android, activate the intercept plugin, and mock API requests and responses within your automation framework using the My Circle app.
Network Interception: How It Works0:55
Explore how network interception captures and analyzes http and https traffic between client and server, using a tool to observe api calls and their request and response data.
Appium Interceptor Plugin Architecture: How It Works1:40
Discover the Appium interceptor plugin architecture, where the APM interceptor plugin sits beside the driver, listens to network traffic, and can modify backend API calls, headers, URLs, and responses.
Features of the Appium Interceptor Plugin: What It Offers0:32
Explore how the Appium 2 interceptor plugin updates outgoing request URLs, modifies request payloads and headers, and adjusts response headers, bodies, and status codes for mock API interactions.

Start the Appium with Appium Interceptor Plugin1:22
Demonstrates starting the APM server, activating the APM interceptor plugin for Appium 2, and running a test with a real device, highlighting plugin activation and APM version requirements.
Framework-Level Changes: A Walkthrough for Integrating the Appium Interceptor Pl1:47
Explore framework-level changes to integrate the APM interceptor plugin in a simple Maven framework, including setting the APM interceptor in capabilities and using a dry driver manager for sessions.

Mocking API Responses to Test Different Text on Mobile App UI8:21
Mock the get matches API by modifying the response payload with the interceptor plugin to swap team names and series name. Then remove the mock to verify production data.
Mocking API Status Code 500: Testing Error Handling on the Login Screen6:04
