Question

Right now with my ui tests using WebdriverIO, I have this in my configuration file:

var baseUrl = 'http://localhost:3000';

global.testParameters = {
  baseUrl: baseUrl
};

This gives me access to my base url in the tests however it has to be fixed in the configuration file and I can't use the --baseUrl option when running wdio command. The reason for this is because from everything I have read, I don't see a way to have access to command line option values in my tests.

Is there a way to access the value of the command line options (specifically --baseUrl) in my actual test files?

Answer 1

You can use the yargs library. Do npm install yargs and in your config file add:

var argv = require('yargs').argv;
var baseUrl = argv.baseUrl;

You can then pass in the baseUrl with --baseUrl <your URL>

You can also make use of the WebdriverIO spec ( wdio.conf.js ) for configuration and create a separate conf.js file for each baseUrl you'd like to run your tests against

Answer 2

You can pass your base location through command line using -baseUrl= like below

wdio --baseUrl=http://[device IP]

You can pass any argument you need using the same way and can access it in wdio.config.js ' onprepare ' event like below

wdio --type=XXX

Then in wdio config

onPrepare: function(config, capabilities) {
    if (process.argv !== undefined && process.argv.length) {
        process.argv.forEach(arg => {
                if (arg.indexOf('--type=') !== -1) {
                    process.env.type = arg.replace('--type=', '');
                }
        });
    }
},
before: function(capabilities, specs) {
      global.type = process.env.type;
}

Now your type is available through-out your workspace as a global variable.
