An application goes through several tiers of testing to guarantee its dependable operation. When an application experiences rapid changes, it first needs to be verified that the current functionality or feature is working properly according to the agile testing process.
If you want to manually test your constantly evolving production code, it is a very difficult and time-consuming operation that will also take up a lot of your effort.
To overcome this solution, many businesses are implementing automated testing to run smoke and regression tests for their online and mobile apps.
It is done to obtain the best, most rapid, and increased test coverage with the help of Appium integration. It would be important to create a test automation framework after making your test automation code reusable and maintainable.

What is a Framework?
Whenever we consider automation, we almost always put money, time, and effort into it. Because any hasty decision results in increased expenses, more time, and subpar product quality. That’s why you should exercise extreme caution while creating an automated test framework.
To achieve the best results, uninterrupted execution, proper maintainability, and high code reuse, the automation framework should be carefully built to combine libraries, test data, and current open-source tools.
The following are some advantages of a strong automated testing framework:
- Because the code is grouped into well-defined packages and is correctly structured, the entire team is aware of the need to build and maintain the code base in accordance with the established standards.
- It can incorporate many components that support the goal of executing test cases, reporting results, recording logs, etc.
- Enabling the reuse of parts or code will increase efficiency during the creation and implementation of automated test scripts.
- By selecting tests to run based on test scenarios and dynamically adjusting the test scope in response to changes, you can reduce the need for expertise.
- It is simpler to create and maintain test cases since test scripts for other modules can be reused.
- Test scripts can be created without reference to the AUT (Application Under Test).
- The framework can be applied to any comparable initiatives carried out internally by teams.
What is Appium?
Appium is a tool for automated testing of online, native, and hybrid apps. It works with several mobile operating systems: Android, iOS, and Windows. Using the same API of Apium, you can build UI tests for several platforms including the mentioned operating systems. As a result, it allows the code to be reused between test scripts or suites for Android, iOS, and Windows.
- Native mobile apps: These apps are created using the Android, iOS, and Windows SDKs and installed directly on the device. There are many platforms like Google Play and Apple Store from which you can download mobile apps.
- Mobile web apps: Mobile web browsers like Chrome and Safari are used to access the web apps. You just need to visit the website and then in-app browsers can access web apps.
- Hybrid applications: These programs use a “webview” a native component that enables interaction with web material, as the core of their design. Both a physical device and a URL in a browser can be used to access hybrid apps.
Building Test Cases with Appium Framework
I have mentioned the procedure and you should follow it in order to create test cases using the Appium framework:
Step 1: From the official website, you just download and install Appium on your computer locally.
Step 2: Install the necessary dependencies. You now need to set up the Java Development Kit (JDK), Android SDK, and Appium client libraries in order to execute Appium tests. These requirements can be downloaded and installed on your computer locally.
Step 3: Create a new Java project. You can utilize an integrated development environment (IDE), such as Eclipse or IntelliJ IDEA to start a new Java project.
Step 4: Include the project’s Appium client library Using the Maven or Gradle build tools, include the Appium client library into the Java project.
Step 5: Write test scenarios by utilizing the TestNG framework and then create them. Appium supports TestNG, a well-liked testing framework for Java applications.
Step 6: Launch the server using the Appium desktop application or the command line. The Apium server will be started
Step 7: Now, you simply need to run the test cases from the command line or the IDE.
Executing Test Cases with Appium Framework
You can easily run your test cases after writing them in the Appium framework using many tools and techniques. Here is a broad overview of running test cases using the Appium framework in this response. The following are some methods for running Appium test cases:
A command-line interface:- You can execute test cases using Appium’s command-line interface (CLI). But before that ensure that your computer has Appium installed in it and have access to the command-line interface in order to run tests.
A majority of well-known IDEs, including Eclipse and IntelliJ IDEA, include built-in support for executing TestNG or JUnit test cases.
By selecting the test runner and the settings of the Appium server, you can set up the IDE to execute your Appium test cases. You have to right-click on the test case file and choose “Run As” -> “TestNG Test” to execute a test case using an IDE.
Tools for Continuous Integration (CI): – You can automate the Appium test case execution by using continuous Appium integration (CI) systems like CircleCI, Travis CI, and Jenkins.
With the help of these tools, you can set up the build pipeline so that the tests are running automatically or after each code revision.
The build pipeline’s test runner and Appium server settings can also be used to execute tests and produce test results.
Here is an example of how to execute an Appium test case using TestNG in Eclipse:
- Right-click on the test case file and select “Run As” -> “TestNG Test”.
- Eclipse launches the Appium server and the test case starts executing on the specified device or emulator.
- After the test execution completes, Eclipse displays the test results in the TestNG view.
- You now view the details of the test execution, including the test case pass/fail status and any error messages associated with it.
Various Test Frameworks for Appium
There are several test frameworks that can be used with Appium to automate the testing of mobile applications.
It is important to choose a framework that is well-suited for the project and can provide the required features and functionalities. Here’s an overview of some of the popular test frameworks: –
TestNG is a popular testing framework used for Java applications that are widely used with Appium. It provides a wide range of features such as data-driven testing, parallel test execution, and the ability to define test dependencies.
JUnit is another popular testing framework for Java applications that can be used with Appium. It provides features such as annotations for test cases, assertions, and the ability to run tests in parallel.
Robot Framework is a generic test automation framework that can be used for both web and mobile applications. It has many simple and easy-to-use syntaxes, supports multiple test libraries, and includes built-in keywords for Appium.
Espresso is a testing framework provided by Google that is specifically designed for Android applications. The simple and concise API, test synchronization, and built-in assertions and matches make this testing framework a convenient one.
XCTest is a testing framework provided by Apple that is specifically designed for iOS applications. It provides features such as assertions, test expectations, and the ability to launch and control the application being tested.
Appium is a popular open-source tool that can be used to automate the testing of mobile applications. It supports various programming languages and platforms and provides a range of features and functionalities that make it a preferred choice for mobile app testing.
When building and executing test cases with Appium, there are various test frameworks that can be used. The choice of the framework depends on various factors such as the programming language, platform, and specific requirements of the project.
Once the test cases are written and the test framework is selected, the test cases can be executed using various methods that I have mentioned in the article above.
