Identifier test sets implemented with JUnit

<source lang="java"> package identifier;

import org.junit.Test; import org.junit.Assert;

public class IdentifierTestCase {

 protected Identifier id;

 @Test 
 public void validate1() {
   id = new Identifier();
   boolean result = id.validateIdentifier("Abcd5");
   Assert.assertEquals(true, result);
 }

 @Test
 public void validate2() {
   id = new Identifier();
   boolean result = id.validateIdentifier("x12345");
   Assert.assertEquals(true, result);
 }

} </source>

Now using fixtures:

<source lang="java"> package identifier;

import org.junit.Before; import org.junit.Ignore; import org.junit.Test; import org.junit.Assert;

public class IdentifierTestCase {

 protected Identifier id;

 @Before
 public void setUp() {
   id = new Identifier();
 }

 @Test 
 public void validate1() {
   boolean result = id.validateIdentifier("Abcd5");
   Assert.assertEquals(true, result);
 }

 @Test
 public void validate2() {
   boolean result = id.validateIdentifier("x12345");
   Assert.assertEquals(true, result);
 }

 @Test
 public void validate3() {
   boolean result = id.validateIdentifier("&123");
   Assert.assertFalse(result);
 }

 @Test
 public void validate4() {
   boolean result = id.validateIdentifier("Inv@lido");
   Assert.assertFalse(result);
 }

 @Test
 public void validate5() {
   Assert.assertNotNull(id);
 }

 @Test(expected=IndexOutOfBoundsException.class)
 public void stringException() {
   String str = new String("JUnit Example");
   str.substring(30);
 }

 @Test(timeout=2000)
 public void looping() {
   boolean result = id.validateIdentifier("Abcd5");
   Assert.assertEquals(true, result);
 }

 @Ignore("Out of the program scope")
 @Test(expected=IndexOutOfBoundsException.class)
 public void stringException2() {
   String str = new String("JUnit Example");
   str.substring(30);
 }

} </source>

And with a parameterized JUnit test case:

<source lang="java"> package identifier;

import org.junit.Assert; import org.junit.Test; import org.junit.Before; import org.junit.runner.RunWith; import org.junit.runners.Parameterized; import org.junit.runners.Parameterized.*;

import java.util.Arrays; import java.util.Collection;

@RunWith(Parameterized.class) public class IdentifierParameterizedTestCase {

 private Identifier id;

 private String param;
 private boolean expected;

 @Before 
 public void initialize() {
   id = new Identifier();
 }

 @Parameters
 public static Collection data() {
   return Arrays.asList(new Object[][]{
     {"Abcd5",     true},
     {"x12345",    true},
     {"&123",      false},
     {"Inv@lido",  false}	
     });
 }

 public ParameterizedTestCase2(
     String param, boolean expected) {
   this.param = param;
   this.result = expected;
 }

 @Test
 public void validate() {
   boolean obtained = id.validateIdentifier(param);
   Assert.assertEquals(result, obtained);
 }

} </source>

Finally, a JUnit test suite to run them all:

<source lang="java"> package identifier;

import org.junit.runner.RunWith; import org.junit.runners.Suite;

@RunWith(Suite.class) @Suite.SuiteClasses({

   IdentifierTestCase.class,
   IdentifierParameterizedTestCase.class

})

public class AllTests { } </source>
