在 C# 中离线时使用 Selenium-WebDriver 测试 Chrome

Question

I am using Chrome, and I would like to be able to run automation tests in C# that tests while the application is offline (I am testing a mobile app with PhoneGap ), and later on get online to complete the tests. Is it possible using WebDriver in Selenium 2 ?

In Google Chrome you can set on developers tool like shown bellow:

But I don't know how to set it automatically on Selenium.

I know there is a way to check if application is online/offline by checking the navigator.onLine property, but I would like to "fake" it's values for testing purposes;

Answer 1

Selenium is only for web based applications, which means that you cannot run your automation tests when application is offline.

It just replicates the user actions / behavior. If your user can access your site being in offline mode, then selenium also can do & vice-versa.

Answer 2

@Tito @Vikram piece of code that works perfect for me:

var driver = new ChromeDriver();
driver.NetworkConditions = new ChromeNetworkConditions()
        { IsOffline = true, DownloadThroughput = 5000, UploadThroughput = 5000, Latency = TimeSpan.FromMilliseconds(5) };

now you are in offline mode. to switch it back you need to set IsOffline = false.

In Selenium4 for C# the property NetworkConditions they promised will be in IWebDriver interface

Answer 3

var driver = new ChromeDriver(); driver.NetworkConditions = new ChromeNetworkConditions() { IsOffline = true, DownloadThroughput = 5000, UploadThroughput = 5000, Latency = TimeSpan.FromMilliseconds(5) };

I can not get this code to work on my .NET6.0 Selenium 4.3.0

Does ChromeNetworkConditions() still exist? If yes, what is the library I should import?
