Nunit Setup Environment in VisualStudio with Example Program

• NUnit is a unit-testing framework for all .Net languages. 
• It is written entirely in C# and has been completely redesigned to take advantage of many .NET language features, for example custom attributes and other reflection related capabilities.
•  NUnit brings xUnit to all .NET languages.

To Setup Environment For NUnit follow the below Steps:

• Download Nunit  from below URL: 

          Download Nunit

  

 

Click on Nunit-2.6.4.msi to download setup

• Navigate to downloaded Nunit-2.6.4.msi and install.

Open Visual Studio File -> New -> Project-> Console Application

• RightClick on solution Explorer and Add new class

 

Add Downloded Reference .dll files in the project 

To find Nunit Reference Library(.dll ) files navigate to installed folder

C:\Program Files (x86)\NUnit 2.6.4\bin\framework

• Add reference library from solution explorer

 

Browse Librery

 

 

 C:\Program Files (x86)\NUnit 2.6.4\bin\framework

 

  Click OK.

    class Checkurl

    {

        [Test]

        public void checklink()

        {

            string actualurl = "http://automationplace.blogspot.com/";

            string expectedurl = "http://automationplace.blogspot.com/";

            Assert.AreEqual(actualurl, expectedurl);

        }

        [Test]

        public void checkurl()

        {

            IWebDriver driver = new ChromeDriver(@"C:\Users\Prashanth_KK\Documents\visual studio 2013\Projects\WebdriverTest\packages\WebDriver.ChromeDriver.26.14.313457.1\tools");

            driver.Navigate().GoToUrl("http://automationplace.blogspot.com/");

            driver.Close();

           

        }

    }

}

 

Open Nunit.exe

List of JUnit annotations With Example

@Test:

• The Test annotation tells JUnit that the public void method to which it is attached can be run as a test case. 
• Any exceptions thrown by the test will be reported by JUnit as a failure. If no exceptions are thrown, the test is assumed to have succeeded. - 

Example Program :

public class MyTestClass {

    @Test

    public void myTestMethod() {

        /**

         * Use Assert methods to call your methods to be tested.

         * A simple test to check whether the given number is equal

         */

int a=10;

int b-10;

       org.junit.Assert.assertTrue(a==b);

    }

 }

@Test(timeout=100):

• Somethimes we need to mesure the performance interms of time. The @Test annotations provides an optional parameter called 'timeout', which causes a test to fail if it takes longer than a specified amount of clock time (measured in milliseconds).

Example Program :

public class MyTestClass {

    @Test@Test(timeout=100)

    public void myTestMethod() {

        /**

         * The IO operation has to be done with in 100 milli seconds. If not,

         * the test should fail.

         */

       ....

       ....

    }

 }

@Before

• When writing tests, it is common to find that several tests need similar objects created before they can run. Annotating a public void method with @Before causes that method to be run before the Test method. The @Before methods of super classes will be run before those of the current class. 

Example Program (in selenium):

public class MyTestClass {

     

    @Before

    public void initialize() {

        Webdriver driver=new FirefoxDriver();

    }

     

    @Test

    public void myTestMethod() {

       

driver.get("http://www.msn.com")

    }

 }

@After :

• If you allocate external resources in a Before method you need to release them after the test runs. Annotating a public void method with @After causes that method to be run after the Test method. All @After methods are guaranteed to run even if a Before or Test method throws an exception. The @After methods declared in superclasses will be run after those of the current class

Example Program (in selenium):

public class MyTestClass {

     

    @Before

    public void initialize() {

        Webdriver driver=new FirefoxDriver();

    }

     

    @Test

    public void myTestMethod() {

       

driver.get("http://www.msn.com")

    }

  @After

    public void close() {

        driver.quit()

    }

 }

//After Running Testcase its close browser

@BeforeClass :

• @BeforeClass causes it to be run once before any of the test methods in the class. The @BeforeClass methods of superclasses will be run before those the current class.

Example Program :

public class MyTestClass {

     

    @BeforeClass

    public void initGlobalResources() {

        /**

         * This method will be called only once per test class.

         */

    }

     

    @Before

    public void initializeResources() {

        /**

         * This method will be called before calling every test.

         */

    }

     

    @Test

    public void myTestMethod1() {

        /**

         * initializeResources() method will be called before calling this method 

         */

    }

     

    @Test

    public void myTestMethod2() {

        /**

         * initializeResources() method will be called before calling this method 

         */

    }

 }

@Ignore :

• Sometimes you want to temporarily disable a test or a group of tests. Methods annotated with Test that are also annotated with @Ignore will not be executed as tests. Also, you can annotate a class containing test methods with @Ignore and none of the containing tests will be executed. Native JUnit 4 test runners should report the number of ignored tests along with the number of tests that ran and the number of tests that failed

 Example Program (in selenium):

public class MyTestClass {

     

    @Before

    public void initialize() {

        Webdriver driver=new FirefoxDriver();

    }

     

    @Test

    public void myTestMethod() {

       

driver.get("http://www.msn.com")

    }

    @Ignore

     @Test

       public void myTestMethod() {

       

driver.close();

    }

     

  @After

    public void close() {

        driver.quit()

    }

 }

Difference between @Before and @BeforeClass annotations

• Test method marked with @Before annotation will be executed before the each @Test method. Means if there are 5 @Test methods in your class then @Before test method will be executed 5 times.
• Test method marked with @BeforeClass annotation will be executed just before the class. Means @BeforeClass method will be executed only once before the class even if there are 5 @Test methods in your class.

Difference between @After and @AfterClass annotations

• Same as @Before annotation, Test method marked with @After annotation will be executed after the each @Test method.
• @AfterClass annotation will be executed only once after last @Test method executed.

Execute bellow given @Before and @After annotations example in your eclipse

package junitpack;

import org.junit.After;

import org.junit.AfterClass;

import org.junit.Before;

import org.junit.BeforeClass;

import org.junit.Test;

import org.openqa.selenium.By;

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.firefox.FirefoxDriver;

public class junittest2 {

 private static WebDriver driver;

 

@Before

public void openbrowser() {

 System.out.print("\nBrowser open");

 driver = new FirefoxDriver();

 driver.manage().window().maximize();

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

}

@After

public void closebrowser() {

 System.out.print("\nBrowser close");

 driver.quit();

}

 @Test

 public void test1() throws InterruptedException{ 

 driver.findElement(By.xpath("//input[@name='fname']")).sendKeys("junittest2 class-test1");

 System.out.print("\njunittest2 class-test1 method is executed");

 Thread.sleep(2000);

 }

 @Test

 public void test2() throws InterruptedException {

 driver.findElement(By.xpath("//input[@name='fname']")).clear();

 driver.findElement(By.xpath("//input[@name='fname']")).sendKeys("junittest2 class-test2");

 Thread.sleep(2000);

 System.out.print("\njunittest2 class-test2 method is executed");

 }

}

When you execute above example in eclipse, Bellow given result will be displayed in console.

Console Output :

Browser open

junittest2 class-test1 method is executed

Browser close

Browser open

junittest2 class-test2 method is executed

Browser close
