コンストラクタで失敗するすべてのテストメソッド[宿題]

Question

私はスーパークラスといくつかのサブクラスを持っています。何らかの理由で、JUnitテストを実行すると、すべてのメソッドが失敗して、サブクラスを作成しようとすると、このエラーメッセージが表示されます。

ソースが見つかりません：このクラスファイルのJARは、JUnit 4に属しています.JUnit 4では、エントリの添付ファイルを変更できません。

は、ここに私のスーパークラス

public class Sequence { 

protected char[] seqarr; 

public boolean isValidLetter(char let){ 
    boolean isValid = false; 
    if (Character.isUpperCase(let) == true || Character.isLowerCase(let) == true){ 
     isValid = true; 
    } 
    return isValid; 
} 


public Sequence(char[] sarr){ 

    boolean check = true; 
    for (int i = 0; i<sarr.length; i++){ 
     if (isValidLetter(sarr[i]) == false){ 
     check = false; 
     break; 
     } 
    } 
    if (check == true){ 
     seqarr = sarr; 
    } 

    if (check == false){ 
     throw new IllegalArgumentException("Invalid sequence letter for class edu.iastate.cs228.hw1.Sequence"); //Need to figure out how to make this say whatever class it came from 

    } 



} 

public int seqLength(){ 
    return seqarr.length; 

} 

public char[] getSeq(){ 
    char[] seqCopy = seqarr; 
    return seqCopy; 

} 

public String toString(){ 
    String stringSeq = ""; 
    for(int i = 0; i < seqarr.length; i++){ 
     stringSeq = stringSeq + seqarr[i]; 
    } 
    return stringSeq; 

} 

public boolean equals(Object obj){ 
    boolean check = false; 
    if (obj != null && (seqarr.toString().toLowerCase() == obj.toString().toLowerCase())){ 
     check = true; 
    } 
    return check; 

} 





} 

は、ここに私のサブクラスの1

public class DNASequence extends Sequence { 


@Override 
public boolean isValidLetter(char let){ 
    return "aAcCgGtT".indexOf(let) != -1; 
} 


public DNASequence(char[] dnaarr){ 
    super(dnaarr); 
} 
} 

だだし、ここでそのサブクラスのテストケースは パブリッククラスDNASequenceTest {

char[] testArrOne = {'a','B','c','D'}; 

@Test 
public void testValidLetter() { 
    String msg = "Method should return true if the character is a/A, c/C, g/G, or t/T"; 
    DNASequence newDNASequence = new DNASequence(testArrOne); 
    assertEquals(msg, true, newDNASequence.isValidLetter('a')); 

    } 


@Test 
public void testValidLetterTwo(){ 
    DNASequence newDNASequence = new DNASequence(testArrOne); 
    assertEquals(false, newDNASequence.isValidLetter('P')); 
} 



@Test 
public void testConstructor(){ 
    String msg = "The constructor should call the super and initialize seqarr to the input if all compnents are valid."; 
    DNASequence newDNASequence = new DNASequence(testArrOne); 
    Sequence newSequence = new Sequence(testArrOne); 
    assertArrayEquals(msg, testArrOne, newDNASequence.getSeq()); 
    assertArrayEquals(msg, testArrOne, newSequence.getSeq()); 
} 
}

Answer 1

問題があります文字が有効であれば各要素をチェックするDNASequenceのコンストラクタの引数として常にtestArrOneを使用します。しかしBとDはではありません。は有効でないため、テストは常にIllegalArgumentExceptionで失敗します。

あなたが唯一の引数として使用するように有効な入力が含まれているテストアレイ作ることができます：

char[] testArrValid = { 'a', 'G', 'c', 'T' }; 

を...

@Test 
public void testValidLetter() { 
    String msg = "Method should return true if the character is a/A, c/C, g/G, or t/T"; 
    DNASequence newDNASequence = new DNASequence(testArrValid); // <-- use here 
    assertEquals(msg, true, newDNASequence.isValidLetter('a')); 
} 

Answer 2

の無効なシーケンス手紙考えられる理由は、あなたがあなたのJUnitテストを実行するために適切なクラスを追加していないされて

@RunWith(springjunit4classrunner.class) 
class DNASequenceTest {
