Selenium, WebDriver Manager, and Electron Desktop Apps - selenium

I'm building out some ui automation tests for an electron app. I have an existing test framework built in C# using Selenium and Appium for web and mobile devices.
I figured out how to start the chrome driver and target the electron app, but to do so, I had to not use the extremely handy WebDriverManager package.
This is my set up
[SetUp]
public void TestSetUp()
{
ChromeOptions chromeOptions = new()
{
BinaryLocation = #"ElectronApp.exe",
};
_driver = new ChromeDriver(#"local driver path", chromeOptions);
}
This works to open up the electron app using Chrome driver. I did have to match the version of Chrome the electron app used and made sure to download that version of the webdriver.
What I want to know is if there's a good way to use WebDriver Manager to set up my driver, but open the electron app.
This was what I was trying:
[SetUp]
public void TestSetUp()
{
ChromeOptions chromeOptions = new()
{
BinaryLocation = #"ElectronApp.exe",
};
ChromeConfig chromeConfig = new();
new WebDriverManager.DriverManager().SetUpDriver(chromeConfig, "98.0");
_driver = new ChromeDriver(chromeOptions);
The 98 is the version of Chrome that the electron app is apparently using -- that's the same version I had to match the driver for.
This is the stack error:
Message:
System.Net.WebException : The remote server returned an error: (404) Not Found.
TearDown : System.NullReferenceException : Object reference not set to an instance of an object.
Stack Trace:
HttpWebRequest.GetResponse()
WebClient.GetWebResponse(WebRequest request)
WebClient.DownloadBits(WebRequest request, Stream writeStream)
WebClient.DownloadFile(Uri address, String fileName)
BinaryService.DownloadZip(String url, String destination)
BinaryService.SetupBinary(String url, String zipPath, String binaryPath)
DriverManager.SetUpDriverImpl(String url, String binaryPath)
DriverManager.SetUpDriver(IDriverConfig config, String version, Architecture architecture)
DesktopTests.TestSetUp() line 41
--TearDown
DesktopTests.Teardown() line 54

I was so focused on the WebDriver Manager, I missed that the chrome version I was specifying wasn't valid. Instead, I used the full version, and it worked great.
[SetUp]
public void TestSetUp()
{
ChromeOptions chromeOptions = new()
{
BinaryLocation = #"ElectronApp.exe",
};
ChromeConfig chromeConfig = new();
new WebDriverManager.DriverManager().SetUpDriver(chromeConfig, "98.0.4758.102");
_driver = new ChromeDriver(chromeOptions);
}

We are unable to detect your camera while passing fake media to experitest chrome browser

I did not get a specific chrome option to work fine when my test is running on the server where we don't have a webcam when started chrome per the java selenium web driver script.
The goal is to mock a camera on the server and pass a fake media stream to the server machine where we don't have a webcam. The script is working fine on the local machine (because the local machine has a webcam) but it's not working on the experitest cloud browser where we don't have a webcam.
How to mock a camera on devices without a camera so that I can run my script through CI pipeline on a server or cloud browser?
The below code is working locally but not on the cloud browsers where we don't have support for the webcam and currently facing the we are unable to detect your camera error when running on a cloud browser

How to test Electron app using selenium and java

Hi Im having an issue with testing an electron app. Up until last week our product was ran on chrome. But now the product has been changed to an electron desktop app and when launched the window isnt picked up.
The flow is basically I open the product on chrome and it appears as a pop up. Previously this was just a chrome pop up but now its an electron app. And now i cnat seem to switch to this window. Im wondering is it possible to switch between the two or do i need a different driver and just test he electron app by itself?
My driver factory is shown here
public class DriverFactory {
private static WebDriver driver;
public static WebDriver startDriver() {
String projectLocation = System.getProperty("user.dir");
// add in elements for logging into the mobile application also - Android and
// iOS.
if (OSValidator.isMac()) {
System.setProperty("webdriver.chrome.driver", projectLocation + "/chromedriver_mac");
} else if (OSValidator.isWindows()) {
System.setProperty("webdriver.chrome.driver", projectLocation + "/chromedriver.exe");
} else {
System.setProperty("webdriver.chrome.driver", projectLocation + "/chromedriver_linux");
}
if (System.getProperty("app.env") != null) { // If coming from Jenkins/Maven goal..
// This is for logging results. Added when investigating crashes on chrome driver. Can be disabled when not needed. 26/03/2020
System.setProperty("webdriver.chrome.verboseLogging", "true");
}
unknown-error-devtoolsactiveport-file-doesnt-exist-while-t
ChromeOptions options = new ChromeOptions();
options.addArguments("start-maximized");
options.addArguments("disable-infobars");
options.addArguments("--disable-extensions");
options.addArguments("--window-size=1920x1080");
options.addArguments("--disable-cache");
//options.addArguments("--headless");
options.addArguments("--disable-application-cache");

//options.addArguments("--no-sandbox"); // Bypass OS security model
options.setPageLoadStrategy(PageLoadStrategy.NORMAL);
driver = new ChromeDriver(options);
//--------------------
return driver;
}
}
It is described here.
https://applitools.com/blog/automating-electron-applications-using-selenium/
You just need to set appropriate options and use same code for the chrome and electron.
#Before
public void setup() {
ChromeOptions opt = new ChromeOptions();
opt.setBinary("/Users/yanir/Downloads/Electron API Demos.app/Contents/MacOS/Electron API Demos");
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability("chromeOptions", opt);
capabilities.setBrowserName("chrome");
driver = new ChromeDriver(capabilities);
if (driver.findElements(By.id("button-about")).size() > 0)
driver.findElement(By.id("button-about")).click();
}

Accept microphone and camera permissions on Edge using selenium

I am running selenium scripts on Edge browser. one of the functionality requires to initiate a audio or video call between two windows. In chrome, we can use 'use-fake-ui-for-media-stream' in chrome options. Is there anything similar for Edge. If there isn't, is there a way to accept these alerts at runtime. I have tried -
driver.switchTo().alert().accept(),
but this also doesn't work, and throws error saying no such alert present
Edited
I am using Edge chromium and java selenium and have set properties as below in code. Still permission pop up shows when script runs
Map<String, Object> prefs = new HashMap<String, Object>();
prefs.put("profile.default_content_settings.popups", 0);
prefs.put("download.default_directory", fileDownloadLocation);
EdgeOptions options= new EdgeOptions();
options.setCapability("prefs", prefs);
options.setCapability("allow-file-access-from-files", true);
options.setCapability("use-fake-device-for-media-stream", true);
options.setCapability("use-fake-ui-for-media-stream", true);
DesiredCapabilities capabilities = DesiredCapabilities.edge;
capabilities.setCapability(CapabilityType.ACCEPT_SSL_CERTS,true);
capabilities.setCapability(CapabilityType.ACCEPT_INSECURE_CERTS,true);
System.setProperty("webdriver.edge.driver", getDriverPath("EDGE"));
driver = new EdgeDriver(options);
driver.manage().window().maximize();
I suggest you make a test with the sample code below. I tried to test with the Edge Chromium browser and it looks like it is not asking the permission popup.
JAVA code:
public static void main(String[] args)
{
System.setProperty("webdriver.edge.driver","\\msedgedriver.exe");
EdgeOptions op=new EdgeOptions();
op.addArguments("use-fake-device-for-media-stream");
op.addArguments("use-fake-ui-for-media-stream");
WebDriver browser = new EdgeDriver(op);
browser.get("https://your_URL_here...");
}
In Selenium 3.141 Version we dont have addArguments() method but in Selenium 4.0.0 alpha version we have addArguments() method
EdgeOptions edgeOpts = new EdgeOptions();
edgeOpts.addArguments("allow-file-access-from-files");
edgeOpts.addArguments("use-fake-device-for-media-stream");
edgeOpts.addArguments("use-fake-ui-for-media-stream");
edgeOpts.addArguments("--disable-features=EnableEphemeralFlashPermission");
driver = new EdgeDriver(edgeOpts);

How to implement headless browser for secure browser (HTTPS) or validate certificate by utilizing PhantomJs in Selenium?

I need to implement Headless Browser for HTTPS (validate certificate). For this I need to write extra line of code.
I have written for browser HTTP and it is working fine.
public class Headless {
public static void main(String[] args)
{
File src=new File("C:\\phantomjs-2.1.1-windows\\bin\\phantomjs.exe");
System.setProperty("phantomjs.binary.path",src.getAbsolutePath());
WebDriver driver=new PhantomJSDriver();
driver.get("https://www.google.co.in/");
System.out.println(driver.getTitle());
}
}
I google it and get some info:-
phantomjs --ignore-ssl-errors=yes;
DesiredCapabilities dcap = new DesiredCapabilities();
String[] phantomArgs = new String[] {
"--ssl-protocol=any",
"--ignore-ssl-errors=true"
};
dcap.setCapability(PhantomJSDriverService.PHANTOMJS_CLI_ARGS, phantomArgs);
PhantomJSDriver driver = new PhantomJSDriver(dcap);
You can read more about the command-line options on this link: Command Line Interface | PhantomJS

How to run Selenium WebDriver test cases in Chrome

I tried this
WebDriver driver = new ChromeDriver();
But I'm getting the error as
Failed tests: setUp(com.TEST): The path to the driver executable must be set by the webdriver.chrome.driver system property; for more information, see code here . The latest version can be downloaded from this link
How can I make Chrome test the Selenium WebDriver test cases?
You need to download the executable driver from:
ChromeDriver Download
Then use the following before creating the driver object (already shown in the correct order):
System.setProperty("webdriver.chrome.driver", "/path/to/chromedriver");
WebDriver driver = new ChromeDriver();
This was extracted from the most useful guide from the ChromeDriver Documentation.
Download the updated version of the Google Chrome driver from Chrome Driver.
Please read the release note as well here.
If the Chrome browser is updated, then you need to download the new Chrome driver from the above link, because it would be compatible with the new browser version.
public class chrome
{
public static void main(String[] args) {
System.setProperty("webdriver.chrome.driver", "/path/to/chromedriver");
WebDriver driver = new ChromeDriver();
driver.get("http://www.google.com");
}
}
You should download the chromeDriver in a folder, and add this folder in your PATH environment variable.
You'll have to restart your console to make it work.
If you're using Homebrew on a macOS machine, you can use the command:
brew tap homebrew/cask && brew cask install chromedriver
It should work fine after that with no other configuration.
You need to install the Chrome driver. You can install this package using NuGet as shown below:
You can use the below code to run test cases in Chrome using Selenium WebDriver:
import java.io.IOException;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
public class ChromeTest {
/**
* #param args
* #throws InterruptedException
* #throws IOException
*/
public static void main(String[] args) throws InterruptedException, IOException {
// Telling the system where to find the Chrome driver
System.setProperty(
"webdriver.chrome.driver",
"E:/chromedriver_win32/chromedriver.exe");
WebDriver webDriver = new ChromeDriver();
// Open google.com
webDriver.navigate().to("http://www.google.com");
String html = webDriver.getPageSource();
// Printing result here.
System.out.println(html);
webDriver.close();
webDriver.quit();
}
}
Find the latest version of chromedriver here.
Once downloaded, unzip it at the root of your Python installation, e.g., C:/Program Files/Python-3.5, and that's it.
You don't even need to specify the path anywhere and/or add chromedriver to your path or the like.
I just did it on a clean Python installation and that works.
Download the latest version of the Chrome driver and use this code:
System.setProperty("webdriver.chrome.driver", "path of chromedriver.exe");
WebDriver driver = new ChromeDriver();
driver.manage().window().maximize();
Thread.sleep(10000);
driver.get("http://stackoverflow.com");
On Ubuntu, you can simply install the chromium-chromedriver package:
apt install chromium-chromedriver
Be aware that this also installs an outdated Selenium version. To install the latest Selenium:
pip install selenium
All the previous answers are correct. Following is the little deep dive into the problem and solution.
The driver constructor in Selenium for example
WebDriver driver = new ChromeDriver();
searches for the driver executable, in this case the Google Chrome driver searches for a Chrome driver executable. In case the service is unable to find the executable, the exception is thrown.
This is where the exception comes from (note the check state method)
/**
*
* #param exeName Name of the executable file to look for in PATH
* #param exeProperty Name of a system property that specifies the path to the executable file
* #param exeDocs The link to the driver documentation page
* #param exeDownload The link to the driver download page
*
* #return The driver executable as a {#link File} object
* #throws IllegalStateException If the executable not found or cannot be executed
*/
protected static File findExecutable(
String exeName,
String exeProperty,
String exeDocs,
String exeDownload) {
String defaultPath = new ExecutableFinder().find(exeName);
String exePath = System.getProperty(exeProperty, defaultPath);
checkState(exePath != null,
"The path to the driver executable must be set by the %s system property;"
+ " for more information, see %s. "
+ "The latest version can be downloaded from %s",
exeProperty, exeDocs, exeDownload);
File exe = new File(exePath);
checkExecutable(exe);
return exe;
}
The following is the check state method which throws the exception:
/**
* Ensures the truth of an expression involving the state of the calling instance, but not
* involving any parameters to the calling method.
*
* <p>See {#link #checkState(boolean, String, Object...)} for details.
*/
public static void checkState(
boolean b,
#Nullable String errorMessageTemplate,
#Nullable Object p1,
#Nullable Object p2,
#Nullable Object p3) {
if (!b) {
throw new IllegalStateException(format(errorMessageTemplate, p1, p2, p3));
}
}
SOLUTION: set the system property before creating driver object as follows.
System.setProperty("webdriver.gecko.driver", "path/to/chromedriver.exe");
WebDriver driver = new ChromeDriver();
The following is the code snippet (for Chrome and Firefox) where the driver service searches for the driver executable:
Chrome:
#Override
protected File findDefaultExecutable() {
return findExecutable("chromedriver", CHROME_DRIVER_EXE_PROPERTY,
"https://github.com/SeleniumHQ/selenium/wiki/ChromeDriver",
"http://chromedriver.storage.googleapis.com/index.html");
}
Firefox:
#Override
protected File findDefaultExecutable() {
return findExecutable(
"geckodriver", GECKO_DRIVER_EXE_PROPERTY,
"https://github.com/mozilla/geckodriver",
"https://github.com/mozilla/geckodriver/releases");
}
where CHROME_DRIVER_EXE_PROPERTY = "webdriver.chrome.driver"
and GECKO_DRIVER_EXE_PROPERTY = "webdriver.gecko.driver"
Similar is the case for other browsers, and the following is the snapshot of the list of the available browser implementation:
To run Selenium WebDriver test cases in Chrome, follow these steps:
First of all, set the property and Chrome driver path:
System.setProperty("webdriver.chrome.driver", "/path/to/chromedriver");
Initialize the Chrome Driver's object:
WebDriver driver = new ChromeDriver();
Pass the URL into the get method of WebDriver:
driver.get("http://www.google.com");
I included the binary into my projects resources directory like so:
src\main\resources\chrome\chromedriver_win32.zip
src\main\resources\chrome\chromedriver_mac64.zip
src\main\resources\chrome\chromedriver_linux64.zip
Code:
import org.apache.commons.io.IOUtils;
import org.apache.commons.lang3.SystemUtils;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import java.io.*;
import java.nio.file.Files;
import java.util.zip.ZipEntry;
import java.util.zip.ZipInputStream;
public WebDriver getWebDriver() throws IOException {
File tempDir = Files.createTempDirectory("chromedriver").toFile();
tempDir.deleteOnExit();
File chromeDriverExecutable;
final String zipResource;
if (SystemUtils.IS_OS_WINDOWS) {
zipResource = "chromedriver_win32.zip";
} else if (SystemUtils.IS_OS_LINUX) {
zipResource = "chromedriver_linux64.zip";
} else if (SystemUtils.IS_OS_MAC) {
zipResource = "chrome/chromedriver_mac64.zip";
} else {
throw new RuntimeException("Unsuppoerted OS");
}
try (InputStream is = getClass().getResourceAsStream("/chrome/" + zipResource)) {
try (ZipInputStream zis = new ZipInputStream(is)) {
ZipEntry entry;
entry = zis.getNextEntry();
chromeDriverExecutable = new File(tempDir, entry.getName());
chromeDriverExecutable.deleteOnExit();
try (OutputStream out = new FileOutputStream(chromeDriverExecutable)) {
IOUtils.copy(zis, out);
}
}
}
System.setProperty("webdriver.chrome.driver", chromeDriverExecutable.getAbsolutePath());
return new ChromeDriver();
}
Download the EXE file of chromedriver and extract it in the current project location.
Here is the link, where we can download the latest version of chromedriver:
https://sites.google.com/a/chromium.org/chromedriver/
Here is the simple code for the launch browser and navigate to a URL.
System.setProperty("webdriver.chrome.driver", "path of chromedriver.exe");
WebDriver driver = new ChromeDriver();
driver.get("https://any_url.com");
