How to use setTransport method of org.openqa.selenium.virtualauthenticator.VirtualAuthenticatorOptions class

You can use Actions class to perform this.

Actions act = new Actions(driver);
WebElement onElement = Your element on which action has to be performed;
act.contextClick(onElement).perform();
act.sendKeys("w").perform();  // If you want the link to open in new tab then use T instead of w

Hope this helps. Happy coding.

Use PhantomJS with BrowserMobProxy. PhantomJS helps us for JavaScript enables pages. The following code works for HTTPS web addresses, too.

Place 'phantomjs.exe' in C drive and you get the 'HAR-Information.har' file in C drive itself.

Make sure you DO NOT put a ' / ' at the end of the url, like

driver.get("https://www.google.co.in/")

It should be

driver.get("https://www.google.co.in");

Otherwise, it won't work.

        server.start(0);
        server.setHarCaptureTypes(CaptureType.getAllContentCaptureTypes());
        server.enableHarCaptureTypes(CaptureType.REQUEST_CONTENT, CaptureType.RESPONSE_CONTENT);
        server.newHar("Google");

        ArrayList<String> cliArgsCap = new ArrayList<>();
        cliArgsCap.add("--proxy=localhost:"+server.getPort());
        cliArgsCap.add("--ignore-ssl-errors=yes");

        //DesiredCapabilities
        DesiredCapabilities capabilities = new DesiredCapabilities();
        capabilities.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true);
        capabilities.setCapability(CapabilityType.SUPPORTS_JAVASCRIPT, true);
        capabilities.setCapability(PhantomJSDriverService.PHANTOMJS_CLI_ARGS, cliArgsCap);
        capabilities.setCapability(PhantomJSDriverService.PHANTOMJS_EXECUTABLE_PATH_PROPERTY,"C:\\phantomjs.exe");

        //WebDriver
        WebDriver driver = new PhantomJSDriver(capabilities);
        driver.get("https://www.google.co.in");

        //HAR
        Har har = server.getHar();
        FileOutputStream fos = new FileOutputStream("C:\\HAR-Information.har");
        har.writeTo(fos);
        server.stop();
        driver.close();
    }
}

The WebDriver interface does not contain the getScreenshotAs() method, because it is possible to have a webdriver unable of taking screenshots - for example the in-memory drivers that don't render the page at all, like HtmlUnitDriver.

In order to have the method, the driver must implement the TakesScreenshot interface which makes it capable to ... well ... take screenshots.

Therefore, you must tell the program somehow that you want to take a screenshot and that you are absolutely sure you can do so. That's what the (TakesScreenshot)driver part is for. In Java, it's called casting and it literally translates to "I know that this driver instance is able to take a screenshot, please cast it to TakesScreenshot type."

If your cast succeeds, everything is fine and the driver object will be cast at run-time to an instance of TakesScreenshot. If your cast fails, however, you'll get a ClassCastExcepion at run-time.

Some examples:

// We already know this is ok, because FirefoxDriver implements (IS-A) TakesScreenshot.
WebDriver driver = new FirefoxDriver();
TakesScreenshot screenshottingDriver = (TakesScreenshot)driver;

// This will fail at run-time, because HtmlUnitDriver does not implement TakesScreenshot;
WebDriver driver = new HtmlUnitDriver();
TakesScreenshot screenshottingDriver = (TakesScreenshot)driver;

// You can use the `instanceof` operator to check:
if (driver instanceof TakesScreenshot) {
    // we can be sure we can take screenshots, the cast will be safe
    ((TakesScreenshot)driver).getScreenshotAs(...);
}

I found a google groups discussion on the topic. These links look like promising alternative to Browsermob:

• Automating the Capture of Web Timings with Selenium 2

With GeckoDriver v0.20.0 and Firefox Quantum v59.0.2 (64-bits) your code block looks good and the log stack trace looks equally good enough sans the log message :

Promise rejected while context is inactive: Message manager disconnected

As per the discussion in Mozilla Support Forum this error seems to be Privacy Badger. In short this issue is caused by an extension that isn't loaded/working properly.

Solution

• Upgrade JDK to recent levels JDK 8u162.
• Upgrade Selenium to current levels Version 3.11.0.
• Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
• Use CCleaner tool to wipe off all the OS chores before and after the execution of your Test Suite.
• If your base Firefox version is too old, then uninstall it through Revo Uninstaller and install a recent GA and released version of Firefox.
• Take a System Reboot.
• Execute your @Test.

tl;dr

Are unresolved promises rejected prior to a window.unload event?

Update

Well, as I mentioned in my Answer your stack trace was fair enough as per current implementations. But personally I haven't seen this trace on my localhost :

Promise rejected while context is inactive: Message manager disconnected

Of-coarse some traces can be dependent of the underlying OS. Now going through the entire discussion Are unresolved promises rejected prior to a window.unload event? the bottom-line seems :

The problem of promises from unloading pages (or indeed script invocation in unloaded pages in general) not being specified very well and not being interoperably implemented is very real. See also https://bugzilla.mozilla.org/show_bug.cgi?id=1058695 where we ended up putting in some mitigations in Gecko that technically don't follow the spec, because technically following the spec requires leaking the world in common cases.... The problem is that there is no spec for this event loop stuff right now, and the spec for Promise is part of ES6, which doesn't really doesn't admit the possibility of Realms needing to go away in some sense, so there's nothing to even raise such issues against.

Hence the conclusion is You are good to race ahead

Well, I would guess that presenceOfElementLocated will be slighty faster because it's just check elements presence on the page while the visibilityOfElementLocated has to check the presence and whether is element visible.

But I think it really doesn't matter from the performance perspective (what's the point if you save 0.001 second during this checking?), you better choose appropriate method depending on your use case.

• use presenceOfElementLocated when you don't care whether if element visible or not, you just need to know if it's on the page
• use visibilityOfElementLocated when you need to find element which should be also visible

Look at the documentation for more info.

For Chromedriver try out with:

String downloadFilepath = "/path/to/download";
HashMap<String, Object> chromePrefs = new HashMap<String, Object>();
chromePrefs.put("profile.default_content_settings.popups", 0);
chromePrefs.put("download.default_directory", downloadFilepath);
ChromeOptions options = new ChromeOptions();
options.setExperimentalOption("prefs", chromePrefs);
DesiredCapabilities cap = DesiredCapabilities.chrome();
cap.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true);
cap.setCapability(ChromeOptions.CAPABILITY, options);
WebDriver driver = new ChromeDriver(cap);

Note:- Use File.separator to handle slashes, it will put syntax as per os it is executing the code. In windows you need to use \\ for path while if you are using linux or mac then use //

Hope this helps. :)

Problem was solved by downgrading the TestNG dependency in build.gradle file from 7.0.1 to 6.14.3

You can't rely on sleeps so you should try this:

WebElement myDynamicElement = (new WebDriverWait(driver, 10))
  .until(ExpectedConditions.presenceOfElementLocated(By.id("myDynamicElement")));

You have a plenty of methods in the ExpectedConditions class.

Here is some info:

Hope you find this useful.
