Starting Selenium Testing with Java and JUnit

This is interesting way of testing web applications, most of the web applications are constantly changed due to new requirements wanted by your beloved business analyst, as most of these guys are technologically handicap changes are asked for even at the UAT stage. The victims of such foolish actions are the hardworking developers, who need to make sure the functionalities are coded and tested. The testing teams do not report bugs coming out of these changes as they do not complete the regression tests on the previously verified functionalities.
So to done away with those saturday evening call that things are not working when sanity done by the users after production deployment selenium can be very helpful. In this post i will let you show you how to setup the selenium testing framework on your machine and run your first JUnit test.
a) We need to download some files to get the framework up and running, click to this link to get to the selenium download page.
Selenium Download Jars
Selenium Download Jars
Download the three files and get the jars from them. Also get the hamcrest and junit.jar from the Junit download page. Make a user library in eclipse and name it appropriately.
In eclipse, create a Java project.
Project Structure in Eclipse for Selenium Java Junit
Project Structure in Eclipse for Selenium Java Junit
As you can see in the picture, the project is a simple Java project with a user library named as Selenium and the test file a class with junit tests. The Selenium lbrary contains all the jars present in downloaded files from the selenium download page.
Lets get to program.
  1. import java.io.File;
  3. import org.junit.After;
  4. import org.junit.Before;
  5. import org.junit.Test;
  6. import org.openqa.selenium.WebDriver;
  7. import org.openqa.selenium.ie.InternetExplorerDriver;
  10. public class SeleniumTest {
  11. WebDriver driver;
  13. @Before
  14. public void setup() throws Exception{
  15. File file = new File("G:/development/selenium/IEDriverServer.exe");
  16. System.setProperty("webdriver.ie.driver", file.getAbsolutePath());
  17. driver = new InternetExplorerDriver();
  19. }
  20. @After
  21. public void tearDown() throws Exception{
  22. driver.quit();
  23. }
  25. @Test
  26. public void test(){
  27. driver.navigate().to("https://www.google.com");
  28. }
  31. }
You need to know that testing a web application is similar to JUnit tests, we get to a page and assert that certain elements on the web page have certain values at certain times. We can provide values to the page and observe its behaviour.
In the above program, we are using @Before to setup the driver, here Internet Explorer driver is being used. @After to breakaway the resources, using the quit method.
The actual test marked by @Test, the test simply gets us to the google.com.
When you run the test you will get these two pages coming one after another.
Internet Explorer Webdriver Server Page

Java Interview : Threads

Java came up with multi threading long time back, still the kind of response it invokes when this topic raises its head during interviews is not very encouraging. If you have attended an java interview, a couple of suppose to be very smart guys also know as lead developers will shower you with questions on multi threading, grilling you down to make sure what you are talking about, even asking you to write fork-join snippets to solve hadoop use cases. But if you are hired and you write a piece code using executor framework, you will be seen with suspicion generally reserved for people with casual shoes at cocktail parties. So here is post to start out thinking about threads. So a path of execution in java is known as a thread, appropriately an instance of Thread class. The main method runs in its own thread and starts up the program execution. If you implement the Runnable interface, you can run in a thread of you own. The Runnable interface has a run() method you implement your...

Spring Framework Interview Notes : Part Two Wiring

Image
The Spring container is the guy responsible to get the train moving when working with the Spring framework.  The dependency magic gets the things working by somehow getting all the stuff up and running. Now somehow we need to indicate to the spring container as to where and how to “wire” these beans. Remember these beans are also known as components. Components combine to form the structure and thus make the functionality. The concept of component scanning or component finding comes into the picture, literally searching the applications to find the beans required to create these beans. @ComponentScan is the annotation used by giving the the base packages where these components are defined using annotation or xml . Spring Framework Interview Wiring You can also use Autowiring with its attributes, which finds the beans by-name or by-type and injects them appropriately. @Component, @ComponentScan, @Autowired, @Named,  @Bean  with requires and quali...
