How to use nonNegative method of org.openqa.selenium.internal.Require class

Attribute validationMessage will return the message, that will be showing if validation fails:

WebElement username = driver.findElement(By.name("uname"));    
String validationMessage = username.getAttribute("validationMessage");

If element has required attribute, browser will show the message after submitting the form:

boolean required = Boolean.parseBoolean(username.getAttribute("required"));

You can check whether entered value is valid:

boolean valid = (Boolean)((JavascriptExecutor)driver).executeScript("return arguments[0].validity.valid;", username);

---

Not: message text and validation is customizable. If you want to test customized validation and message.

Here test code for custom validation(Java, TestNG):

Assert.assertTrue(Boolean.parseBoolean(username.getAttribute("required")), "Username is required and message should be showin");
Assert.assertEquals(username.getAttribute("validationMessage"), "My custom message", "Message text control");

username.sendKeys("@vasya ");
Assert.assertTrue((Boolean)((JavascriptExecutor)driver).executeScript("return arguments[0].validity.valid;", username), "Username has special characters");

YOu can get the source code through svn here it appears:

http://code.google.com/p/selenium/source/checkout

Once you have downloaded that,

In eclipse, find the jar in 'referenced libraries', right click -> properties

enter the location of the src, in the 'Java Source Attachment' edit box.

You are using javascript that scrolls the main window, if you want to scroll a element, you should first get the element by id, then change the its scrollLeft property:

JavascriptExecutor js = (JavascriptExecutor)driver; 
js.executeScript(
    "document.getElementById('gvLocationHorizontalRail').scrollLeft += 250", "");

If you instead want to change the scrollbar that moves up and down, you should change the scrollTop property.

You need to have an instance of WebDriver, e.g.:

@Bean
public WebDriver webDriver() {
    return new FirefoxDriver();
    //OR return new ChromeDriver();
}

in one of your configuration classes. That would be anything annotated with @Configuration or an annotation which includes this; in the most basic Spring Boot application (as used in Spring Boot examples), this would probably be something like this:

@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

    // Your beans go here

}

because @SpringBootApplication is annotated with @SpringBootConfiguration which is annotated with @Configuration.

I found the work around as below

1. Open terminal
2. Navigate to path where your chromedriver file is located
3. Execute any one of the below commands

Command1: xattr -d com.apple.quarantine <name-of-executable>

Example

/usr/local/Caskroom/chromedriver 
$ xattr -d com.apple.quarantine chromedriver 

(or)

Command2: spctl --add --label 'Approved' <name-of-executable>

Source: https://docwhat.org/upgrading-to-catalina

Note: This will work only with the file(s) where the above command is executed. If a new chromedriver is downloaded then the command has to be executed again on the newly downloaded file

Just the other day i've answered something similar to this so it's still fresh. The reason your code is failing is if the alert is not shown by the time the code is processed it will mostly fail.

Thankfully, the guys from Selenium WebDriver have a wait already implemented for it. For your code is as simple as doing this:

String alertText = "";
WebDriverWait wait = new WebDriverWait(driver, 5);
// This will wait for a maximum of 5 seconds, everytime wait is used

driver.findElement(By.xpath("//button[text() = \"Edit\"]")).click();//causes page to alert() something

wait.until(ExpectedConditions.alertIsPresent());
// Before you try to switch to the so given alert, he needs to be present.

Alert alert = driver.switchTo().alert();
alertText = alert.getText();
alert.accept();

return alertText;

You can find all the API from ExpectedConditions here, and if you want the code behind this method here.

This code also solves the problem because you can't return alert.getText() after closing the alert, so i store in a variable for you.

You can either use the crx file of the extension or point to a directory it's installed in. Assuming you have it installed, you'll need to add ChromeOptions to your new ChromeDriver:

ChromeOptions options = new ChromeOptions();
options.addArguments("load-extension=/path/to/extension");
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability(ChromeOptions.CAPABILITY, options);
ChromeDriver driver = new ChromeDriver(capabilities);

See here for more details and walkthrough.

EDIT: to see your extensions path, navigate to chrome://version and look at 'Profile Path'. In that folder look for 'Extensions' folder. The extension ID for AdBlock Plus is cfhdojbkjhnklbpkdaibdccddilifddb. So the path/to/extension should be something like (Windows):

C:\Users\<user>\AppData\Local\Google\Chrome\User Data\<profile>\Extensions\cfhdojbkjhnklbpkdaibdccddilifddb

You can do it by adding Chrome's command line switches "--lang".

Basically, all you need is starting ChromeDriver with an ChromeOption argument --lang=es, see API for details.

The following is a working example of C# code for how to start Chrome in Spanish using Selenium.

ChromeOptions options = new ChromeOptions();
options.addArguments("--lang=es");
ChromeDriver driver = new ChromeDriver(options);

Java code should be pretty much the same (untested). Remember, locale here is in the form language[-country] where language is the 2 letter code from ISO-639.

public WebDriver getDriver(String locale){   
    System.setProperty("webdriver.chrome.driver", "driver/chromedriver.exe");
    ChromeOptions options = new ChromeOptions();
    options.addArguments("--lang=" + locale);
    return new ChromeDriver(options);
}

public void initializeSelenium() throws Exception{
    driver = getDriver("es"); // two letters to represent the locale, or two letters + country
}

Check the below links:

• Implicit Wait - It instructs the web driver to wait for some time by poll the DOM. Once you declared implicit wait it will be available for the entire life of web driver instance. By default the value will be 0. If you set a longer default, then the behavior will poll the DOM on a periodic basis depending on the browser/driver implementation.

• Explicit Wait + ExpectedConditions - It is the custom one. It will be used if we want the execution to wait for some time until some condition achieved.
