Tried everything and it is not related to chrome driver issue as same is working fine with webdriver-java native APIs.

回答1:

Unless you've set ignoreSynchronization, the fact that you're navigating to a non angular app (google.com) is messing it up.

Try

browser.driver.get('http://google.com');
browser.switchTo().alert().accept();

or

browser.ignoreSynchronization = true
browser.get('http://google.com');
browser.switchTo().alert().accept();

回答2:

Sometimes the alert takes a time until it appears, you can try adding a wait before you make an accept:

browser.ignoreSynchronization = true
browser.get('http://google.com');
browser.wait(protractor.ExpectedConditions.alertIsPresent(), 10000);
browser.switchTo().alert().accept();

回答3:

This is what I did, so that it does not fail if no alert is open:

browser.ignoreSynchronization = true;
browser.get('http://google.com');
browser.switchTo().alert().then(function() {
    browser.switchTo().alert().accept();
}, function(){});
browser.ignoreSynchronization = false;

回答4:

    browser.get("your.address.com");

    browser.switchTo().alert().then(function(alert) {
        alert.accept();
    }).catch(function(error) {

    });
