Simulate press hard key in protractor

Question

I am using Protractor for testing my web application. During the use of the app, I want to press a hard key on the device, like the home screen, then the app will be minimized and I will see the device's home screen. After that, I want to tap again on the app, and I want to see the screen I was before tapping on the home screen key.

• By any chance, Protractor is able to simulate this action? If not, which tool do you recommend I can integrate with Protractor?
• Do you think it is a good approach to automate just this touch scenario?

Answer 1

Protractor supports all webdriverjs keys

HOME is one of them , you can use these in protractor using hte "protractor" global function

protractor.key.HOME

and could be used with sendKeys

 element.sendKeys(protractor.key.HOME)

 browser.actions().sendKeys(protractor.Key.HOME).perform();
