Selenium Automation Framework

An Automation Framework is collection of assumptions,concepts and practices you bring in while developing the automation project, so it helps in constituting a work platform or support for automated testing.It would be great, if the framework is application independent.

If you look into the any existing framework,it will be block of function libraries for reporting , error handling , and driver scripts.So the test automation framework is an execution environment for automated tests. It is the overall system in which our tests will be automated.

What is a Framework?

In general, a framework is a real or conceptual structure intended to serve as a support or guide for the building of something that expands the structure into something useful.

Prior to knowing about the Hybrid Test Automation Framework, we should know about the existing frameworks. Generally we have,
  • Data Driven Framework
  • Test Script Modularity Framework
  • Keyword Driven Framework
  • Test Library Architecture Framework
  • Hybrid Framework

Why do we need Automation framework?

Using Framework, we can solve many issues like
  • Writing code once and reusing it. Significant Reduction in Testing Cycle Time
  • Running the script with different set of data.
  • Executing the scripts end-to-end without any manual intervention. ( If any error occurs from tool or application, Script run will stop. If we use framework, it will skip or fail that testcase and run with the next testcase.)
  • With basic knowledge on tool also anyone can run and write the script. (All the script, Keywords has been written by experts, we have to know how to use those keywords)
  • Can able to run scenarios by selecting YES or NO. (Modular Driven Framework)
  • Maintenance becomes very easy.
Combination of above all framework is nothing but Hybrid Driven Framework.
Example: In an Timetracker application, We have 5 scenarios.
  • Login into application and create a Project and logout
  • Login into application and create Modules under project and logout
  • Login into application and create different users( Approver, Verify, Normal) and logout
  • Login into application create timesheets and logout
  • Login into application and delete timesheets and logout
Now write a script for all 5 scenarios using any automation tool.
If we write a script for all 5 scenarios, it will become a big script and we are repeating the same script again and again. So to overcome this, we have to go for Function Driven Framework

Function Driven Framework: Dividing the scripts into functions and reusing them.

Write a script for one time. Make it as a function and reuse the same function
  • Read all the scenarios.
  • Identify the repeated steps.
  • Convert them into functions
Examples: Login(), Logout(), CreateProject()�. Functions

Advantages :

  • Write once (saves time)
  • Reusable
  • Easy Maintenance

Disadvantages :

  • Data is hardcoded, we can�t run with multiple sets of data.
  • Data Driven Framework: is a framework where test input and output values are read from data files (Excel, CSV, Database) and are loaded into variables in captured or manually coded scripts. If we see the above example, For Login(uname) we can run the script with any data picking it from excel or CSV.

Data-Driven Frameworks

A data-driven framework is where test input and output values are read from data files (ODBC sources, CVS files, Excel files, DAO objects, ADO objects, and such) and are loaded into variables in captured or manually coded scripts. In this framework, variables are used for both input values and output verification values. Navigation through the program, reading of the data files, and logging of test status and information are all coded in the test script. This is similar to table-driven testing (which is discussed shortly) in that the test case is contained in the data file and not in the script; the script is just a "driver," or delivery mechanism, for the data. In data-driven testing, only test data is contained in the data files.

Keyword-Driven Framework

This requires the development of data tables and keywords, independent of the test automation tool used to execute them and the test script code that "drives" the application-under-test and the data. Keyword-driven tests look very similar to manual test cases. In a keyword-driven test, the functionality of the application-under-test is documented in a table as well as in step-by-step instructions for each test. In this method, the entire process is data-driven, including functionality.

Before getting into the framework, lets discuss on what are the external files which will be required. The list of files that will be required in addition to selenium client driver and selenium server jar files are as below

Purpose:

To build a Hybrid Test Automation Framework which can be used across different web based applications. In this approach, the endeavor is to build a lot of applications independent reusable keyword components so that they can directly used for another web application without spending any extra effort. With this framework in place, whenever we need to automate a web based application, we would not need to start from scratch, but use the application independent keyword components to the extent possible and create application specific components for the specific needs.

Driver Script:

Example codes,

Example, Create an instance of WebDriver

    WebDriver driver = new FirefoxDriver();

Example, Navigate to the Totsy home page

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

Example Find an element by ID, className, and (ummm...)

    WebElement searchBox = driver.findElement(By.name("someElement"));

Example, Display the title of the page

    System.out.println("Title: " + driver.getTitle());

Example, Mouse hover to the Element

    WebElement menuOption = driver.findElement(By.xpath("//a[normalize-space()='Registrar']"));
    Actions builder = new Actions(driver);    
    builder.moveToElement(menu).build().perform();
    menuOption.click();

Example, JavaScripts in Selenium

    ((JavascriptExecutor)driver).executeScript("document.getElementById('someElement').click();");

Example, JQuery in Selenium

    HtmlUnitDriver drv = new HtmlUnitDriver(BrowserVersion.FIREFOX_3_6);
    drv.setJavascriptEnabled(true);
    try {
     jQueryFactory jq = new jQueryFactory();
     jq.setJs(drv);

     drv.get("http://google.com");
     jq.query("[name=q]").val("SeleniumJQuery").parents("form:first").submit();

        String results = jq.queryUntil("#resultStats:contains(results)").text();   
        System.out.println(results.split(" ")[1] + " results found!");
          } finally {
               drv.close();
               }

Example, Ajax in Selenium

    FluentWait<By> fluentWait = new FluentWait<By>(By.tagName("TEXTAREA"));
    fluentWait.pollingEvery(100, TimeUnit.MILLISECONDS);
    fluentWait.withTimeout(1000, TimeUnit.MILLISECONDS);
    fluentWait.until(new Predicate<By>() {
        public boolean apply(By by) {
            try {
                return browser.findElement(by).isDisplayed();
            } catch (NoSuchElementException ex) {
                return false;
            }
        }
    });
    browser.findElement(By.tagName("TEXTAREA")).sendKeys("text to enter");    

Example, Selenium Regex

Selenium supports a few methods that help match text patterns. However, selenium locators don�t accept regular expressions. Only patterns or values accept them.

Example, Globbing:

    selenium.click("link=glob:*Gifts"); // Clicks on any link with text suffixed with 'Gifts'
    selenium.verifyTextPresent("glob:*Gifts*");

Example, Regular Expressions:[regexp, regexpi]

    selenium.click("link=regexpi:^Over \\$[0-9]+$");  //matches links such as 'Over $75', 'Over $85' etc

Example, Contains:

    selenium.highlight("//div[contains(@class,'cnn_sectbin')]");  //highlights the first div with class attribute that contains 'cnn_sectbin'
    selenium.highlight("css=div#cat_description:contains(\"to last\")");  //locating a div containing the text 'to last' using css selector

Example, Starts-with:

    selenium.click("//img[starts-with(@id,'cat_prod_image')]");  //clicks on the first image that has an id attribute that starts with 'cat_prod_image'
    selenium.click("//div[starts-with(@id,'tab_dropdown')]/a[last()]");  //clicks on the last link within the div that has a class attribute starting with 'tab_dropdown'
    selenium.click("//div[starts-with(@id,'tab_dropdown')]/a[position()=2]"); //clicks on the second link within the div that has a class attribute starting with 'tab_dropdown'
    selenium.highlight("css=div[class^='samples']"); //highlights div with class that starts with 'samples'

Example, Ends-with:

    selenium.highlight("css=div[class$='fabrics']"); //highlights div with class that ends with 'fabrics'
    selenium.click("//img[ends-with(@id,'cat_prod_image')]"); //clicks on the first image that has an id attribute that ends with 'cat_prod_image'

Example, A Log4J example Java class

The following Java Log4J example class is a simple example that initializes, and then uses, the Log4J logging library for Java applications. As you can see the configuration is pretty simple.

    package com.devdaily.log4jdemo;

    import org.apache.log4j.Category;
    import org.apache.log4j.PropertyConfigurator;
    import java.util.Properties;
    import java.io.FileInputStream;
    import java.io.IOException;

    /**
     * A simple Java Log4j example class.
     * @author alvin alexander, devdaily.com
     */
    public class Log4JExample
    {
      // our log4j category reference
      static final Category log = Category.getInstance(Log4JDemo.class);
      static final String LOG_PROPERTIES_FILE = "lib/Log4J.properties";

      public static void main(String[] args)
      {
        // call our constructor
        new Log4JExample();

        // Log4J is now loaded; try it
        log.info("leaving the main method of Log4JDemo");
      }

      public Log4JExample()
      {
        initializeLogger();
        log.info( "Log4JExample - leaving the constructor ..." );
      }

      private void initializeLogger()
      {
        Properties logProperties = new Properties();

        try
        {
          // load our log4j properties / configuration file
          logProperties.load(new FileInputStream(LOG_PROPERTIES_FILE));
          PropertyConfigurator.configure(logProperties);
          log.info("Logging initialized.");
        }
        catch(IOException e)
        {
          throw new RuntimeException("Unable to load logging property " + LOG_PROPERTIES_FILE);
        }
      }
    }
