Versions

angular 6
node v8.9.4
npm v6.1.0
Windows 10.

Repro steps

After upgrading project to Angular 6 an e2e testing stopped to passing additional command line arguments.
Command:
ng e2e my-project arg1 arg2 arg3

The log given by the failure

NodeJS.Process.agrv[] array includes only 2 default arguments without arg1 arg2 arg3

Desired functionality

Argument should be passed as it was with Angular 5.

Inability to pass additional args through is affecting our upgrade from 5.2 to 6. Any timeline for when this will be fixed ?

For context we pass a "shards" arg to ng test, which is used in karma.conf to configure the karma-parallel plugin. Unable to do that now and given how slow angular unit tests are, this is a deal breaker.

Would really like to be able to do something like the following:
ng e2e <e2e-project-name> --capabilities.chromeOptions.binary="custom/path/chrome/binary"

Is this possible?

@jgf5013 most likely not. What you can do now is use npm to run e2e command and pass argument to it.
npm run e2e --my-param=test -- --suite=someSuite // args after -- are append to the command listed in package.json
Then you can access value of my-param via process.env.npm_config_my-param (or something similar on process.env)
