Code To Simulate A Mouse Hover

In the BankRate.com test, one must hover over the text “MORTGAGES” in order to be able to display its drop-down menu, where the link to the “Mortgage Calculator” is found. Here’s the code to simulate that mouse hover in Selenium. Use it immediately after the line driver.get(baseUrl + "/");

Actions action = new Actions(driver);

action.moveToElement(driver.findElement(By.linkT

ext("MORTGAGES"))).perform();

Capturing A Screenshot In Selenium Code

WebDriver driver = new FirefoxDriver();

driver.get("http://www.google.com/");

File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);

// Now you can do whatever you need to do with it, for example copy somewhere

FileUtils.copyFile(scrFile, new File("c:\\tmp\\screenshot.png"));

Maven Dependency Code

<dependency>

<groupId>org.seleniumhq.selenium</groupId>

<artifactId>selenium-java</artifactId>

<version>2.35.0</version>

</dependency>

…will do the basic job. To start the Selenium server as part of running your tests with Maven:

<dependency>

<groupId>org.seleniumhq.selenium</groupId>

<artifactId>selenium-server</artifactId>

<version>2.35.0</version>

</dependency>

For Verifying A Page’s “Look”

At the 2013-10-10 OCJUG presentation, someone asked if Selenium could test if a page actually ended up displaying exactly as expected – or if an image was shifted by a pixel or two.

At the time I said I wasn’t aware of a way to test a page’s “look” via Selenium, but then I received a tip:

1. Take a snapshot of the “correct look” of a page via Selenium code

2. Crop at (X,Y) for a certain size A by B 1. This is now your “correct” snapshot

3. Modify the Selenium code to: 1. Take a snapshot of the web page each test

2. Crop at (X,Y) for size A by B

3. Compare the “correct” snapshot that just-taken-and-cropped snapshot with file size, file hashes, via ImageMagick, or some other methodology

Framework For Your Website

Google the following terms:

• Data Driven Testing (aka DDT) – Involves data mapping and canonical schema mapping between

DB and WebObjects, in this sense, it's also a part of Data Integrity Checking effort

• Component Modeling

• Domain Specific Language (or Layer) (aka DSL) – Component Model and DSL is a pure OOD (Object Oriented

Design) and that's the core engine to give you an action-command type script interface
