Desired functionality.

running e2e tests with firefox

Mention any other details that might be useful.

• the current setup is good for chrome (only)
• download latest gecko via

./node_modules/.bin/webdriver-manager update

(webdriver-manager update updates the global one, which is not used).

• when starting the

node_modules/protractor/node_modules/webdriver-manager/selenium/selenium-server-standalone-3.4.0.jar

it requires the -Dwebdriver.gecko.driver system property set.

• looked in the code, but did not see how the jar file was called

When using directConnect: true the error is

this seems to be a port issue (connecting to 4444 rather 49152)

This isn't a bug in Angular CLI as the out-of-the-box configuration is only intended to work directly for chrome. To work with firefox you need to manually configure it.

We do provide the ng e2e --no-webdriver-update flag so that the CLI will not try to auto-update the chrome webdriver.

Other than that, it's really up to the user to configure firefox/protractor properly. The CLI only starts the dev server and then starts protractor.
