Junit Test Suite

Test Suite means combined multiple test cases . when I run test suite all test case associated with suite will execute. In Junit we will create test suite with two ways Test Runner class or using annotation  @RnWith and @Suite, here is a example for both type. I have created two Junit test case “JunitTest1.java” and “JunitTest2.java”

package com.test;

import org.junit.*;

public class JunitTest1 {

    @BeforeClass

    public static void beforeClassAnnotation() {        

      System.out.println("@BeforeClass - for junit class 1");

    }

    @AfterClass

    public static void afterClassAnnotation() {       

      System.out.println("@AfterClass - for junit class 1");

    }  

    @Test

    public void testAnnotation() {       

        System.out.println("@Test - first class test method");

    }    

}

package com.test;

import org.junit.*;

public class JunitTest2 {

    @BeforeClass

    public static void beforeClassAnnotation() {        

      System.out.println("@BeforeClass - for junit class 2");

    }

    @AfterClass

    public static void afterClassAnnotation() {       

      System.out.println("@AfterClass - for junit class 2");

    }  

    @Test

    public void testMethod2() {       

        System.out.println("@Test - Second class test method");

    }    

}

Test Suite using @RunWith and @Suite annotation.

package com.test;

import org.junit.runner.RunWith;

import org.junit.runners.Suite;

@RunWith(Suite.class)

@Suite.SuiteClasses({

      JunitTest1.class ,JunitTest2.class

})

public class JunitTestSuite {

}

Run above suite file using Junit Test you will see as below log is generated.

@BeforeClass - for junit class 1

@Test - first class test method

@AfterClass - for junit class 1

@BeforeClass - for junit class 2

@Test - Second class test method

@AfterClass - for junit class 2

Test suite using Test runner  class.

package com.test;

import org.junit.runner.JUnitCore;

import org.junit.runner.Result;

public class TestRunner {

   public static void main(String[] args) {

      Result result = JUnitCore.runClasses(JunitTest1.class);      

      result = JUnitCore.runClasses(JunitTest2.class);    

   }

}

Run above suite file using java console you will see as  below log is generated.

@BeforeClass - for junit class 1

@Test - first class test method

@AfterClass - for junit class 1

@BeforeClass - for junit class 2

@Test - Second class test method

@AfterClass - for junit class 2
