The only reliable way of using XPath in Selenium WebDriver for text with apostrophes (single quotes) is to use double quotes for the expression of the XPath. In order to find how to use XPath to locate WebElements in Chrome browser you can check our previous article.

For example, for the code below:

driver.findElement(By.xpath("//*[@text='" + text + "']"))

you need to change to:

driver.findElement(By.xpath("//*[@text=\"" + text + "\"]"))

This way, it will not matter if your text contains apostrophes or not, and you’ll be able to select web elements by text that contains apostrophes (single quotes). is a cloud testing platform, use Automated Website Testing Service to build functional tests and automate regression manual tests of your website, more details.

Here is how you can find all the Links on a Webpage with Selenium WebDriver in Java.

All you need to do is to create a list of all WebElements, and then iterate thorough the list of links to print the link and the text of the link:

List allLinks = driver.findElements(By.tagName("a"));

System.out.println("All links found on web page are: " + allLinks.size() + " links");

for (WebElement link : allLinks) {

//print the links i.e. or

//print the links text

To get the link you can call the “getAttribute” method on the link WebElement passing “href” as its argument which will print the links as i.e. or is a cloud testing platform:

Reasons for 500 Internal Server Errors when doing GET or POST requests


How did we find out about these strange 500 Internal Server errors?

A few of our customers were getting sometimes strange 500 Internal Server errors when running load tests against their application even though when they were trying to make the GET or POST request from the browser it was working without a problem.

We decided to give them a hand finding why this might happen. The answer to the puzzle is quite simple but unless you know about the problem it might take a few hours to get to the bottom of the it.

The problem is that many web applications by default do not take into consideration the fact that some of the following headers might not be present in the client requests:

Accept-Encoding:gzip, deflate, sdch, br
User-Agent:Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.106 Safari/537.36

Why a lot of web applications do not consider the need to check that these headers are really sent in the user request ?

The answer is very simple, because all the browsers by default add these headers to all the requests.


What did we decide to implement in the LoadFocus platform to help our customers ?

For helping our customers we decided to add the possibility for the user to get all those headers added to their requests by only clicking one button.

Also we decided to add a few hints that will be displayed on the result page in case the requests return 500 Internal Server error.

We are going to present how you can mouseover an web element using Selenium WebDriver. The code below is straight forward:

  • first we identify the element to be hovered in the web page, here is how you can find web elements using Selenium WebDriver.
  • hover (mouseover) functionality is provided in Selenium WebDriver with the help of the Actions class, which provides the ability to move the mouse over an element.

WebElement web_Element_To_Be_Hovered = webDriver.findElement(By.cssSelector(selector_For_Web_Element_To_Be_Hovered));
Actions builder = new Actions(getDriver());

The build() method generates a composite action containing all actions so far, ready to be performed (and resets the internal builder state, so subsequent calls to build() will contain fresh sequences).

Also, if we want to click a web element after hovering the first element, we can do that by waiting for the element to be clickable, in order to interact with it.


With you can easily automate the repetitive manual testing of your site, schedule your automated tests to run from cloud instances at scheduled times.
