When it comes to mobile app testing, flexibility and efficiency are critical. With the help of the well-known open-source automation technology Appium, testers may automate mobile apps on several platforms. Appium's command line interface (CLI), which lets testers use the terminal or command prompt to interact with Appium, is one of its most potent features. We will examine the features of Appium's CLI and how you can use it to automate your mobile testing process in this post.
Appium - Command Line
With the Appium CLI (Command-Line Interface) tool, you can communicate with the Appium server and conduct automated tests for mobile apps right from the command line. Without requiring a graphical user interface, you may use the Appium CLI to start the Appium server, install and run apps on mobile devices or emulators, and run test scripts.
Appium CLI Features
- Server Management: You can use the command line to start, stop, and restart the Appium server. Give details about the host, port, and logging level of the server.
- Device Administration: For testing, connect to real devices or emulators. Install, open, and remove applications from emulators or linked devices.
- Automated Testing: Run test scripts directly in a variety of programming languages (such as Java, Python, and JavaScript)
Getting Started with Appium CLI
Before diving into the intricacies of Appium's CLI, it's essential to ensure that you have Appium installed on your system. You can install Appium using npm (Node Package Manager) by running the following command: The first step is check whether the Node.js is installed on your system or not .
To check, open the terminal and run the following command:
node --version
If Node.js is installed in your system then it will reutrn the version of node.js, otherwise it will throw an error 'error is not recognised'. To download Node.js, visit the official https://nodejs.org/en/download
Choose the node installer according to your system. Window users need to check the bit size before downloading. Once download is finished , run and proceed with the installation. Now restart the terminal and check for the version again by running the command -> node --version. It will return the node version. Mac users can use node -v and npm -v commands to verify the installation and the version details.
To install Appium, run the command given below:
npm install -g appium
Once Appium is installed, you can start the Appium server by simply typing appium in your terminal or command prompt.
