Chromedriver option is missing for this command “npm init wdio .”

If you are encountering the error message “Chromedriver option is missing for this command ‘npm init wdio .’”, you are not alone. This error occurs when you try to initialize a WebdriverIO project using the command “npm init wdio .” but haven’t specified the Chromedriver option. In this blog post, we will explore two solutions to fix this issue.

Solution 1: Manually add Chromedriver option

The first solution is to manually add the Chromedriver option to the configuration file. Follow the steps below:

1. Open the wdio.conf.js file in the root directory of your project.
2. Locate the capabilities section in the configuration file.
3. Add the following code snippet to specify the Chromedriver option:

capabilities: [{
  maxInstances: 1,
  browserName: 'chrome',
  'goog:chromeOptions': {
    binary: 'chromedriver',
    args: ['--headless', '--disable-gpu']
  }
}],

Make sure to adjust the args array according to your requirements. The --headless option runs Chrome in headless mode, and the --disable-gpu option disables the GPU acceleration.

Solution 2: Use the WebdriverIO CLI

If you prefer a more automated approach, you can use the WebdriverIO CLI to generate the configuration file with the Chromedriver option included. Follow the steps below:

1. Install the WebdriverIO CLI globally by running the following command:

npm install -g @wdio/cli

2. Navigate to the root directory of your project.
3. Run the following command to generate the configuration file:

npx wdio config

4. Follow the prompts to configure your project. When asked for the browser, select “chrome”.
5. Once the configuration file is generated, open it and locate the capabilities section.
6. Ensure that the Chromedriver option is included, similar to the code snippet provided in Solution 1.

By using the WebdriverIO CLI, you can quickly generate the configuration file with the necessary Chromedriver option.

With either of these solutions, you should be able to fix the “Chromedriver option is missing” error and successfully initialize your WebdriverIO project.

Happy testing!
