Selenium test, disconnect browser connection during test and enable it again

Question

I run the test using Selenium Webdriver (Java) and halfway through the test. I want to disable my browser, follow a few steps and re-enable the connection to the browser. Is there an easy way to do this, or perhaps change the browser proxy to nonexistent (offline emulation) and return to something real again? I need to save browser cache, browser local storage area and browser cookies between online, offline and online again.

thanks

Perhaps you can fake it by setting the desired WebDrivers PageLoadTimeout.

In C #, this worked for me:

driver.Manage().Timeouts().SetPageLoadTimeout(new TimeSpan(0)); 

I'm sure in Java it will be something like this:

 driver.manage().timeouts().pageLoadTimeout(0, TimeUnit.SECONDS); 

After you finish doing this, you can return it for 30 seconds or something else, as some messages indicated that it was the default.

Source for the LoadTimeout page: https://selenium.googlecode.com/git/docs/api/java/org/openqa/selenium/WebDriver.Timeouts.html

And the default time: https://sqa.stackexchange.com/questions/2606/what-is-seleniums-default-timeout-for-page-loading

if u uses java and windows 7 then you can call cmd and pass release to disconnect the network and use / update to turn on the network. it works for me. Process p = Runtime.getRuntime().exec("cmd /c ipconfig /release");
p = Runtime.getRuntime().exec("cmd /c ipconfig /renew");

I am struggling with this exact problem.

If you are ready to look beyond selenium, then chrome-remote-interface can substitute an account.

Here is the relevant code snippet

 const CDP = require('chrome-remote-interface'); const fs = require('fs'); CDP(async (client) => { function setOffline(){ return Network.emulateNetworkConditions({offline: true, latency: 100, downloadThroughput: 750 * 1024 / 8, uploadThroughput: 250 * 1024 / 8}); } const {Page, Network} = client; try { await Page.enable(); await Network.enable(); await setOffline(); await Page.navigate({url: 'https://github.com'}); await Page.loadEventFired(); const {data} = await Page.captureScreenshot(); fs.writeFileSync('scrot.png', Buffer.from(data, 'base64')); } catch (err) { console.error(err); } finally { await client.close(); } }).on('error', (err) => { console.error(err); });
