Unable to launch multiple browser instances in Protractor

问题

My config file is just launching 1 instance of chrome. I'm expecting it to open 2. This is my config multi capabilities.

multiCapabilities: [
{
browserName: 'chrome',
logName: 'Chrome - Suite 1',
shardTestFiles: false,
maxInstances: 1,
maxSessions: 1,
specs: ['test/protractor/test.js']
},
{
browserName: 'Chrome',
logName: 'Chrome - Suite 2',
shardTestFiles: false,
maxInstances: 1,
maxSessions: 1,
specs: ['test/protractor/test2.js']
}
],

Now I am facing the error as below:

    /usr/local/lib/node_modules/protractor/node_modules/selenium- 
webdriver/lib/error.js:546
      throw new ctor(message);
            ^
SessionNotCreatedError: Unable to create session from {
"desiredCapabilities": {
  "specs": [
    "test\u002fprotractor\u002ftest2.js"
  ],
  "maxSessions": 1,
  "logName": "Chrome - Suite 2",
  "count": 1,
  "browserName": "Chrome",
  "maxInstances": 1,
  "shardTestFiles": false
},
"capabilities": {
  "firstMatch": [
    {
      "browserName": "Chrome"
    }
  ]
}
}

Any help to make it launch 2 instances is highly welcome.

回答1:

Make your config like below.

exports.config = {

  // Capabilities to be passed to the webdriver instance.
  capabilities: {
    browserName: 'chrome',

    // allows different specs to run in parallel.
    // If this is set to be true, specs will be sharded by file
    // (i.e. all files to be run by this set of capabilities will run in parallel).
    // Default is false.
    shardTestFiles: true,

    // Maximum number of browser instances that can run in parallel for this
    // set of capabilities. This is only needed if shardTestFiles is true.
    // Default is 1.
    maxInstances: 2,       
  },

  // Spec patterns are relative to the current working directly when
  // protractor is called.
  specs: ['spec.js', 'spec2.js'],
}

Hope it help you..
