Today we are announcing our new live online training session “The Ultimate Selenium WebDriver Testing & Hands-on Guide” which will take place on Saturday, 10th December 2016 – 10:00 UTC Time.

This Revolutionary New Selenium WebDriver training session has a length of 5 hours and is going to be presented in english.

“The Ultimate Selenium WebDriver Testing & Hands-on Guide” is a step-by-step online guide anyone can use to start running automated user interface tests immediately, using proven strategies we’ve used ourselves.
“The Ultimate Selenium WebDriver Testing & Hands-on Guide” is not so much a tutorial as it is a hands-on guide and an interactive session that will handhold you all the way to understanding software architecture, what should / should not be tested and where you should start.

By the time you finish this guide, you will not only have a dozen ideas about different testing strategies to build your own custom automated testing framework, but you’ll know exactly what it takes to implement each one of them and how to use Selenium WebDriver to achieve this goal.

The price of £100 per this live session is a bargain comparing to how much other tutorials cost, and the amount of information you’ll get after this will actually be tremendous. Be one of the few that will know the most important testing tips and tricks which will make you look like a testing guru.

 

This training is brought to you by LoadFocus.com – Cloud Testing Platform.

Here are details related to using waits with Selenium WebDriver in Java. According to the Selenium documentation, at the moment, there are two different type of waits: explicit and implicit.

After you understand how to locate elements with Selenium WebDriver, you have to focus on waiting for elements to appear, be visible, be clickable.

Waiting is an automated step, elapse a certain amount of time, before execution can continue. Choose to use Explicit Waits or Implicit Waits. As a side note, you should not mix implicit and explicit waits.

Implicit Waits in Selenium WebDriver

An implicit wait tells 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 implicit wait is set for the life of the WebDriver object instance.

WebDriver driver = new FirefoxDriver();
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

//use a URL that delays loading elements
driver.get("http://www.example.com/");
WebElement myDynamicElement = driver.findElement(By.id("myDynamicElement"));

You can set the implicit wait when you first instantiate the WebDriver:

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

This specifies the amount of time the driver should wait when searching for an element if it is not immediately present.

Explicit Waits in Selenium WebDriver

An explicit wait represents defined code for certain conditions or behaviours to occur/happen before continued to the next step.

Enroll Now for the new Online Course: How to Find XPath for Web Elements in Chrome and Firefox Browsers.

 

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).

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. http://example.com or https://www.example.com
System.out.println(link.getAttribute("href"));

//print the links text
System.out.println(link.getText());
}

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. http://example.com or https://www.example.com

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:application/json;charset=utf-8,*/*
Accept-Encoding:gzip, deflate, sdch, br
Accept-Language:en-US,en;q=0.8,ro;q=0.6
Cache-Control:no-cache
Connection:keep-alive
Host:your_host:8080
Pragma:no-cache
Referer:https://your_host:8080/ui/index
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());
builder.moveToElement(web_Element_To_Be_Hovered).build().perform();

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.


WebDriverWait wait = new WebDriverWait(driver, 5);
wait.until(ExpectedConditions.elementToBeClickable(By.cssSelector(selector_For_Element_To_Be_Click_After_Hover)));
driver.findElement(By.cssSelector(selector_For_Element_To_Be_Click_After_Hover)).click();

The most important part is identifying the element right after the first web element was hovered (mouseover), otherwise we’ll get an exception that the element is not available.
