Desired functionality

I would like to tag Protractor tests and run them using tags. Currently ng e2e is not supporting --grep option:
Unknown option: '--grep'

This feature would solve a problem of running tagged tests and with different tags.

@DmitrijK @alan-agius4 Is there any workaround to run only tagged tests(Example: '@smoke' and '@regression') from a specific test suite? In case, if there is one please let me know.

I am also running up against this issue.
The issue appears to be that the Angular Protractor Builder does not support the grep argument (or invertGrep for that matter). See the schema.

@PoovinPR what we did to get around it is to use a base protractor.conf file, then create additional protractor.conf files that extend the base with the jasmineNodeOpts.grep property.

protractor.conf.js

...
exports.config = {
    // All the normal config here
}

protractor.<tagName>.conf.js

var globalConf = require('./protractor.conf.js').config;
globalConf.jasmineNodeOpts.grep = '<tagName>';
globalConf.jasmineNodeOpts.invertGrep = true; // exclude the above tag
exports.config = globalConf;

Then since --protractorConfig is a recognized argument for the Protractor Builder, you can run ng e2e <e2e-app> --protractorConfig protractor.<tagName>.conf.js.

This sounds like a reasonable idea. It's flexible and useful enough. This isn't a major priority right now, but we would welcome any PRs implementing this.
