WebDriver waits

Web application automation is depends on so many factors. Browser, network speed ...etc. We should write unquie code for running in all environments. For achieveing that we need to wait for WebElements before performing any operation on that.

Here we will see some built-in waits in WebDriver.

implicitlyWait

1	WebDriver driver = new FirefoxDriver();

2	driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);

3	driver.get("http://www.google.co.in");

4	WebElement myElement = driver.findElement(By.id("someId"));

Implicit waits are basically your way of telling WebDriver the latency that you want to see if specified web element is not present that WebDriver looking for. (Click here for more information). This will be useful when certain elements on the webpage will not be available immediately and needs some time to load.

pageLoadTimeout

1	driver.manage().timeouts().pageLoadTimeout(30, SECONDS);

Sets the amount of time to wait for a page load to complete before throwing an error. If the timeout is negative, page loads can be indefinite.

setScriptTimeout

1	driver.manage().timeouts().setScriptTimeout(30,SECONDS);

Sets the amount of time to wait for an asynchronous script to finish execution before throwing an error.

isTextPresent() ? In WebDriver

While automation web applications in some places we want/need to check particular text is present or not.

In WebDriver (Selenium 2), there is no predefined method for checking this. (In Selenium-RC isTextPresent("text") built-in method exist ) So we need to implement our own method to achieve this.

Let us consider you are searching for text "WebDriver"


boolean isTextPrest=false;

Method-1

 isTextPrest=driver.findElement(By.tagName("body")).getText().contains("WebDriver");  

Method-2

 isTextPrest=driver.findElement(By.xpath("//*[contains(.,'WebDriver')]")).isDisplayed();  

Method-3

 Selenium sel=new WebDriverBackedSelenium(driver, "");  
 isTextPresent=sel.isTextPresent("WebDriver");  

FYI : Method-1 will take more time than remaining (comparatively)

Happy Coding :)

XPath indexing

Q : What does //td[2] mean?
A : All td elements in that page (document), that are second child of their parent.


Q : Will //td[2] return only one element?
A :  No, there may be many such elements. (second child td of their parent)


 if you've any doubts regarding this xpath indexing post it in comments section.

Finding elements within iframe using firebug

Firebug command line allows executing JavaScript expressions within context of the current page. Firebug also provides a set of built in APIs and one of them is cd().

Lets consider below iframe

                <iframe id="testID" name="testName" src="iframe.html" />

• cd(document.getElementById("testID").contentWindow); switch to a frame by ID
• cd(window.frames[0]); switch to the first frame in the list of frames
• cd(window.frames["testName"]); switch to a frame using by name
• cd(window.top); switching back to the top level window

Happy Coding .. :)

isElementPresent? Method another way

“we can use the findElements() call, and then we just need to check that the size of the list returned is 0.

You can write logic like this.

List elements = driver.findElements(By.Id("element id"));
if(elements.size()==0)
        No element found
else
        Element found
