Browser is restarted automatically if 'shardTestFiles': true

[avient]

Hi there!

I have a lot of specs files.
I run them in one browser instanse ('shardTestFiles': false) and DO NOT restart Browser between tests.
So tests are going smoothly and everything is OK.

But I want to run tests in several Browser instances:
so I set
'shardTestFiles': true
and
'maxInstances': 4.
And now Browser is restarted automatically after each spec file, even when
restartBrowserBetweenTests: false.
So it dramatically slows down my tests.

Is it possible not to restart Browser after each spec file?

Hi there!

Your question is better suited for StackOverflow or Gitter. Please ask a question there with the 'protractor' tag or post in the Gitter Channel to get help.

From the the getting help section of the README:

Please ask usage and debugging questions on StackOverflow
(use the "protractor" tag) or in the Angular discussion group. (Please do not ask support questions here on Github.)

Thanks!

Currently there is no way to execute tests in parallel without restarting web browser after each spec. I have created an Pull Request that solves this issue. #4836.
To enable this feature you have to create custom spec scheduler and add it to the configuration. Here is an example:

function shardScheduler(specs, capabilities) {
  const numberOfShards = capabilities.maxInstances;
  if(numberOfShards > 1) {
      const bucketSize = Math.ceil(specs.length/numberOfShards);
      const shards = [];
      let start = 0
      while (start < specs.length) {
          let end = start + bucketSize;
          if ( end > specs.length) {
              end = specs.length
          }
          shards.push(specs.slice(start,end));
          start = end;
      }
      return shards;
  }
  return [specs];
}

exports.config = {
  ........
  capabilities: {
    shardTestFiles: shardScheduler,
    'browserName': 'chrome',
    maxInstances: 2
  },
........
}
