Useful tips in Selenium WebDriver

The integration of WebDriver API has been a major change in Selenium in terms of browser automation. WebDriver has a well-designed object-oriented API that provides a simpler and more concise programming interface. Along with Selenium, WebDrivers can make direct calls to the browsers by directly using the browser’s built-in support for automation. The following figure shows the Selenium Web server as an intermediary that interacts with the script (in Python / PHP) and the browser (Chrome / IE / Safari / Firefox).

Script-Selenium-Browser

Here are some useful tips on using Selenium WebDriver

1. Open different browsers in web driver
a. Firefox Driver
WebDriver webDriver= new FirefoxDriver();
b. Chrome Driver
WebDriver webDriver= new ChromeDriver();
c. Internet Explorer Driver
WebDriver webDriver= new InternetExplorerDriver();
d. Safari Driver
WebDriver webDriver= new SafariDriver();

2. Open new Tab
webDriver.findElement(By.cssSelector(“body”)).sendKeys(Keys.CONTROL +”t”);

3. Close newly opened tab
webDriver.findElement(By.cssSelector(“body”)).sendKeys(Keys.CONTROL +”w”);

4. Wait for an element to be available in page
a. Method one

WebDriverWait wait = new WebDriverWait(driver, 30);

WebElement element =
wait.until(ExpectedConditions.elementToBeClickable(By.xpath(‘xpath-of-element’)));

b. Method two

List<WebElement> sElements = webDriver.findElements(By.xpath(xPath));

int sCount = 0;

while (sCount < sTime) {

if (sElements.size() > 0) {

break;

} else {

Thread.sleep(1000);

sCount = sCount + 1;

sElements = webDriver.findElements(By.xpath(xPath));

}

5. Drag and Drop items

Actions builder = new Actions(driver);

Action dragAndDrop = builder.clickAndHold(someElement)

.moveToElement(otherElement)

.release(otherElement)

.build();

dragAndDrop.perform();

6. Execute Java Script statement

JavascriptExecutor jsx = (JavascriptExecutor) driver;

jsx.executeScript(“sample code”);

7. Enable elements that will be visible or enabled only on mouse over

${iid}= webDriver.findElement(By.id(“id123″)).getAttribute(attributevalue);
Execute Javascriptvar innerDiv = document.querySelector(‘DOM-
element#${iid}’);innerDiv.style.display=”block”;
DOM-element can be div or input or li

8. Upload a file – We can do it in 2 methods

a. Method1 – If the upload button is defined as DOM element – ‘input’ use following method
WebElement w = getWebDriver().findElement(By.xpath(element-xpath));
w.sendKeys(path-of-file);
b. Method2 – If the upload button is not defined as – ‘input’

String filePath = “path-of-file-for-upload”;
JavascriptExecutor jsx = (JavascriptExecutor) driver;
jsx.executeScript(“document.getElementById(‘fileName’).value=’” + filePath + “‘;”);

9. Switch between frames

WebElement iframe = getWebDriver().findElement(By.xpath(“//iframe xpath”));

getWebDriver().switchTo().frame(iframe);

10. Switch back to default content from the frame

After performing actions in the iframe that was switched we might switch back to default content to
perform further activities

getWebDriver().switchTo().defaultContent();

11. Switch to new window

for (String winHandle : webDriver.getWindowHandles()) {

webDriver.switchTo().window(winHandle);

}

12. Switch tab

String oldTab = webDriver.getWindowHandle();

ArrayList<String> newTab = new ArrayList<String>(

webDriver.getWindowHandles());

webDriver.switchTo().window(newTab.get(0));

13. Wait for page load

webDriver.manage().timeouts().pageLoadTimeout(100, TimeUnit.SECONDS);

14. Scroll window to bottom, to view elements

webDriver = getCurrentWebDriver();

JavascriptExecutor jsx = (JavascriptExecutor) webDriver;

jsx.executeScript(“window.scrollTo(0, document.body.scrollHeight);”);

15. Scroll window to specific height -scrollHeight is the value passed to function

webDriver = getCurrentWebDriver();

JavascriptExecutor jsx = (JavascriptExecutor) webDriver;

jsx.executeScript(“window.scrollTo(0, ” + scrollHeight + “);”);
