How to use JavascriptException class of org.openqa.selenium package

Best Selenium code snippet using org.openqa.selenium.JavascriptException

JavascriptException `org.openqa.selenium.JavascriptException`

The WebDriver error - javascript error, happens a user script execution fails.

The reason for the execution failure is generally provided in the error message, including a stacktrace of the error given by the browser's JavaScript engine.

Example

The below script attempts to use an undefined variable. This usually is thrown as a ReferenceError by JavaScript. It is caught by WebDriver and is serialized as a JavaScript error:


1from selenium import webdriver
2from selenium.common import exceptions
3
4session = webdriver.Firefox()
5try:
6    session.execute_script("return foo")
7except exceptions.JavascriptException as e:
8    print(e.message)

Output:

JavascriptException: ReferenceError: foo is not defined

Solution:

Manually verify the JS in dev tool console

Selenium chromedriver disable logging or redirect it java

I got it to work with Firefox webdriver by the following:

profile.SetPreference("network.automatic-ntlm-auth.trusted-uris", "google.com");
driver = new FirefoxDriver(profile);

driver.Navigate().GoToUrl("http://user:pwd@google.com");

There are multiple ways of doing it. Here's an article you might want to have a look.

Test WYSIWYG editors using Selenium WebDriver

Send keys directly

This approach is the one you have tried and didn't work. Please try make sure your locators to <iframe> and <body> are correct. Otherwise I'd suggest using JavaScriptExecutor for more stable solutions.

Set innerHTML

WaitTool.waitForElementPresent(Browser.instance, By.className("cke_wysiwyg_frame"), 10);
WebElement iframe = Browser.instance.findElement(By.className("cke_wysiwyg_frame"));
Browser.instance.switchTo().frame(iframe);

WebElement description = Browser.instance.findElement(By.cssSelector("body"));
(JavascriptExecutor)Browser.instance.executeScript("arguments[0].innerHTML = '<h1>Set text using innerHTML</h1>'", description);

Use CKEditor's native API

// no need to switch iframe
(JavascriptExecutor)Browser.instance.executeScript("CKEDITOR.instances.ckeditor.setData('<h1>Native API text</h1> Editor')");

Implicit and Explicit Waits

Implicit Wait

An implicit wait is to tell WebDriver to poll the DOM for a certain amount of time when trying to find an element or elements if they are not immediately available. The default setting is 0. Once set, the implicit wait is set for the life of the WebDriver object instance.

driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

Explicit Wait + Expected Conditions

An explicit waits is code you define to wait for a certain condition to occur before proceeding further in the code. The worst case of this is Thread.sleep(), which sets the condition to an exact time period to wait. There are some convenience methods provided that help you write code that will wait only as long as required. WebDriverWait in combination with ExpectedCondition is one way this can be accomplished.

WebDriverWait wait = new WebDriverWait(driver, 10);
WebElement element = wait.until(
        ExpectedConditions.visibilityOfElementLocated(By.id("someid")));

You can redirect the output to a file or just discard it:

            // redirect console output from chromedriver to the file chromedriver_log.txt in the target folder
            DriverService.Builder<ChromeDriverService, ChromeDriverService.Builder> serviceBuilder = new ChromeDriverService.Builder();
            ChromeDriverService chromeDriverService = serviceBuilder.build();
            chromeDriverService.sendOutputTo(new FileOutputStream("target/chromedriver_log.txt", true));

            webDriver = new ChromeDriver(chromeDriverService, options);

If you want to just discard the output then use NullOutputStream.NULL_OUTPUT_STREAM insted off new FileOutputStream("target/chromedriver_log.txt", true)

This should select the element you want

./ancestor::div[contains(concat(' ', @class, ' '), ' x-grid-view ')][1]

In plain English: Of all the ancestor div elements that have ' x-grid-view ' in their class, select the first (closest) one.

Notes:

I concat spaces as a defensive measure to prevent partial matches.
current() is an XSLT function, not an XPath one. It has no meaning outside of XSLT. The current node is expressed as . in XPath.

https://stackoverflow.com/questions/10076618/xpath-to-find-ancestor-node-containing-css-class

Use the xpath as shown below:

driver.findElements(By.xpath("//input[contains(@text,\"WE'd\")]"));

Hope this helps.

Just check for a single dialog-confirm class:

driver.findElement(By.className("dialog-confirm")).click();

Or, use a CSS Selector:

driver.findElement(By.cssSelector("button.dialog-confirm")).click()

https://stackoverflow.com/questions/27529967/how-to-find-button-element-with-webdriver

Webdriver has findElements API, which can be used for this purpose..

List<WebElement> allElements = driver.findElements(By.xpath("//div[@id='...']/ul/li")); 

for (WebElement element: allElements) {
      System.out.println(element.getText());
}

Top Programming Languages Helpful For Testers

There are many debates going on whether testers should know programming languages or not. Everyone has his own way of backing the statement. But when I went on a deep research into it, I figured out that no matter what, along with soft skills, testers must know some programming languages as well. Especially those that are popular in running automation tests.

Best Python Testing Frameworks

After being voted as the best programming language in the year 2018, Python still continues rising up the charts and currently ranks as the 3rd best programming language just after Java and C, as per the index published by Tiobe. With the increasing use of this language, the popularity of test automation frameworks based on Python is increasing as well. Obviously, developers and testers will get a little bit confused when it comes to choosing the best framework for their project. While choosing one, you should judge a lot of things, the script quality of the framework, test case simplicity and the technique to run the modules and find out their weaknesses. This is my attempt to help you compare the top 5 Python frameworks for test automation in 2019, and their advantages over the other as well as disadvantages. So you could choose the ideal Python framework for test automation according to your needs.

Difference Between Severity and Priority in Testing

As a software tester, you’re performing website testing, but in between your software is crashed! Do you know what happened? It’s a bug! A Bug made your software slow or crash. A Bug is the synonym of defect or an error or a glitch. During my experience in the IT industry, I have often noticed the ambiguity that lies between the two terms that are, Bug Severity vs Bug Priority. So many times the software tester, project managers, and even developers fail to understand the relevance of bug severity vs priority and end up putting the same values for both areas while highlighting a bug to their colleagues.
