About Selenium server
Of writing WebdriverIO tests, it’s important to ensure that you have set up WebdriverIO correctly. This involves meeting the following prerequisites:Install Node.js:Before proceeding, verify that Node.js is installed on your computer. To confirm its installation, open the command-line interface (CLI) and execute the following commands:node -vnpm -vIf Node.js is appropriately installed, these commands will display the respective versions of Node.js and npm.Install WebdriverIO:Afterward, you need to install WebdriverIO. Execute the provided commands in your command prompt to install WebdriverIO:npm install webdriverioThis command will use npm (Node Package Manager) to fetch and install the latest stable version of WebdriverIO.Install Selenium Server Utility:WebdriverIO relies on Selenium Server for browser automation. To install Selenium Server Utility globally, use the following command:npm install -g selenium-standaloneThis command will install the Selenium Standalone Server, which is required for running browser tests with WebdriverIO.Update Selenium Standalone Server and Browser Drivers:To ensure you have the latest versions of the Selenium Standalone Server and browser drivers, run the following command:selenium-standalone installThis command will update the Selenium Standalone Server and download the necessary browser drivers (such as ChromeDriver or GeckoDriver).Start Selenium Standalone Server and Browser:Before executing your test scripts, you need to start the Selenium Standalone Server and launch the desired browser. Use the following command:selenium-standalone startThis command will initiate the Selenium Standalone Server and start the browser specified in your test scripts. Make sure to keep the Selenium Standalone Server running in the background while executing your tests.Configuring WebdriverIO for the first testTo set up WebdriverIO for your first test, follow these steps:Create the project workspace:Open your command-line interface (CLI) and enter the following commands to create a project workspace directory and navigate into it:mkdir WebdriverioTestProjectcd WebdriverioTestProjectInitialize package.json:To initialize a package.json file for your project, run the following command:npm init -yThis command will generate a package.json file with the default configuration.Install WebdriverIO CLI:Install the WebdriverIO Command Line Interface (CLI) globally by running the following command:npm install -g @wdio/cliThe WebdriverIO CLI will install, which will give useful tools for organizing and executing your WebdriverIO tests.Create a WebdriverIO config file:Generate a WebdriverIO config file using the following command:npx wdio configThis command will initiate a configuration setup process where you can choose various options based on your requirements. You can configure the test environment, specify the framework, set the location of test specs, choose a reporter, and define the test execution mode (synchronous or asynchronous).Create the test specs folder:Create a folder to store your test specs by executing the following command:mkdir -p ./test/specsThis command will create a directory structure with a specs folder inside the test folder to hold your test files.Create the test script file:Create a test script file where you will write your automation test script by running the following command:touch ./test/specs/webdriverioTestScript.jsThis command will create a webdriverioTestScript.js file inside the specs folder, ready for you to write your test code.Test Automation Using Selenium and WebdriverIOWebdriverIO is built on top of Selenium, a widely used automation framework for web applications. By integrating with Selenium, WebdriverIO offers a robust solution for web

Webdriver Manager A selenium server and browser driver manager for your end to end tests. This is the same tool as webdriver-manager from the Protractor repository.Note: Version 9 and lower please reference pose/webdriver-manager. If there are features that existed in version 9 and lower, please open up an issue with the missing feature or a create a pull request.Getting Startednpm install -g webdriver-managerSetting up a Selenium ServerPrior to starting the selenium server, download the selenium server jar and driver binaries. By default it will download the selenium server jar and chromedriver binary.webdriver-manager updateStarting the Selenium ServerBy default, the selenium server will run on startOther useful commandsView different versions of server and driver files:webdriver-manager statusClear out the server and driver files. If webdriver-manager start does not work, try to clear out the saved files.webdriver-manager cleanRunning / stopping server in background process (stopping is not yet supported on standalone server 3.x.x):webdriver-manager start --detachwebdriver-manager shutdownHelp commandsWedriver-manager has a main help option: webdriver-manager help. There are also other built in help menus for each of the commands. So for example, if you would like to look up all the flag options you can set in update, you could run webdriver-manager update help.Here are a list of all the commands with help:webdriver-manager update helpwebdriver-manager start helpwebdriver-manager clean helpwebdriver-manager status helpOther topics:mobile browser supportprotractor supportset specific versions
