在等待量角器与页面同步时刷新时发生错误，在捕获警报时

Question

I am getting this error while I refresh the page and catch the alert:

Failed: Error while waiting for Protractor to sync with the page: "both angularJS testability and angular testability are undefined. This could be either because this is a non-angular page or because your test involves client-side navgation, which can interfere with Protractor's bootstrapping. See http://git.io/v4gXM for details".

Please see the code used below:

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

Answer 1

The Alert isn't an Angular Alert, in which case you should tell Angular you're not testing an Angular Application anymore.

browser.waitForAngularEnabled(false); 

Then proceed with the rest of your code after

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

If you want it to behave again in an Angular way (in terms of waiting for HTTPS requests etc) then you will need to re-enable it after accepting your alert

browser.switchTo().defaultContent();
browser.waitForAngular();
browser.waitForAngularEnabled(true);
