Question

Given this JUnit test, write a SentenceCounter class that makes the tests pass:

import static org.junit.Assert.*;

import org.junit.Before;

import org.junit.Test;

/**

* Tests that will make us practice writing loops

*/

public class TestSentenceCounter

{

private static final String SENTENCE1 =

"This is my sentence.";

private static final String SENTENCE2 =

"These words make another sentence that is longer";

private SentenceCounter sc1;

private SentenceCounter sc2;

  

/**

* Create two instances we can play with

*/

@Before

public void setup()

{

sc1 = new SentenceCounter(SENTENCE1);

sc2 = new SentenceCounter(SENTENCE2);

}

  

/**

* Make sure the instance variable is correct

*/

@Test

public void testConstructor()

{

assertEquals(SENTENCE1, sc1.getSentence());

assertEquals(SENTENCE2, sc2.getSentence());

}

  

/**

* Returns an integer containing the number of blanks

* in the String.

*/

@Test

public void testCounterBlanks()

{

assertEquals(3, sc1.countBlanks());

assertEquals(7, sc2.countBlanks());

}

  

Answer 1

public class SentenceCounter {

    private String sentence;

    public SentenceCounter(String sentence) {
        this.sentence = sentence;
    }

    public String getSentence() {
        return sentence;
    }
}
