こんにちは、私はjunitを使用しようとしていますが、うまくいきません。junit test with Eclipse
ここに私のコードです。
package safe;
import java.lang.reflect.*;
import java.util.Collections;
import java.util.Comparator;
import java.util.List;
import safe.SafetyException;
public class SafetyInspector {
public static boolean isSafe(Class<?> clazz) throws SafetyException{
if (clazz.equals(Object.class)) return true;
if (clazz == null) {
throw new SafetyException();
}
Field fields[] = clazz.getDeclaredFields();
for(Field f: fields){
f.setAccessible(true);
int mod = f.getModifiers();
if (Modifier.isFinal(mod)){
continue;
}
else if (Modifier.isPrivate(mod)){
Class<?> typeArray[] = new Class<?>[1] ;
typeArray[0] = f.getType();
try {
Method mSet = clazz.getMethod("set" + f.getName().substring(0, 0).toUpperCase() + f.getName().substring(1),typeArray);
int modMet = mSet.getModifiers();
if(!Modifier.isPublic(modMet)) return false;
if(!mSet.getReturnType().equals(void.class)) return false;
}
catch (SecurityException e) {
throw new SafetyException();
}
catch (NoSuchMethodException e) {
return false;
}
try {
Class<?> typeArray2[] = new Class<?>[1] ;
Method mGet = clazz.getMethod("get" + f.getName().substring(0, 0).toUpperCase() + f.getName().substring(1),typeArray2);
int modMet2 = mGet.getModifiers();
if(!Modifier.isPublic(modMet2)) return false;
if(!mGet.getReturnType().equals(f.getType())) return false;
}
catch (SecurityException e) {
throw new SafetyException() ;
}
catch (NoSuchMethodException e) {
return false;
}
}
}
return isSafe(clazz.getSuperclass());
}
public static void sort(List<Class<?>> classes) throws SafetyException{
for (int i = 1; i < classes.size(); i++) {
for (int j = 0; j < classes.size() - i; j++) {
if (compare(classes.get(j), classes.get(j + 1)) > 0) {
swap(classes, j);
}
}
}
}
public static void reset(Object object) throws SafetyException{
Class c = object.getClass();
Field fields[] = c.getDeclaredFields();
for(Field f :fields){
if (!isSafe(f.getClass()))
{
f.setAccessible(true);
try{
if(!f.getClass().isPrimitive()){
}
else if(f.getClass().equals(boolean.class)){
f.setBoolean(object, false);
}
else{
f.set(object, 0);
}
}
catch(Exception e)
{
throw new SafetyException();
}
}
}
}
private static int compare(Class<?> o1, Class<?> o2) throws SafetyException {
Field[] fields1 = o1.getDeclaredFields();
int count1 = 0;
for (Field f : fields1){
if (isSafe(f.getClass())) count1++;
}
Field[] fields2 = o2.getDeclaredFields();
int count2 = 0;
for (Field f : fields2){
if (isSafe(f.getClass())) count2++;
}
if (count1 == count2)
return o1.getName().compareTo(o2.getName());
else return count1- count2;
}
private static void swap(List<Class<?>> list, int j) {
Class<?> temp = list.get(j);
list.set(j, list.get(j+1));
list.set(j + 1, temp);
}
};
ここに私が与えたコードjunitテストがあります。
package test;
import static org.junit.Assert.assertEquals;
import java.util.Collections;
import java.util.LinkedList;
import java.util.List;
import org.junit.Test;
import safe.SafetyException;
import safe.SafetyInspector;
public class SafetyInspectorTest {
@Test
public void testIsSafeEmployee() throws SafetyException {
assertEquals(false, SafetyInspector.isSafe(Employee.class));
}
@Test
public void testResetEmployee() throws SafetyException {
Employee e = new Employee(123,3000);
SafetyInspector.reset(e);
assertEquals(0, e.id);
assertEquals(3000, e.getSalary());
}
@Test
public void testSort() throws SafetyException {
List<Class<?>> sortedClasses = new LinkedList<Class<?>>();
sortedClasses.add(Employee.class);
List<Class<?>> classes = new LinkedList<Class<?>>(sortedClasses);
Collections.shuffle(classes);
SafetyInspector.sort(classes);
assertEquals(sortedClasses, classes);
}
}
私がsafetyInspectorTestをjunitTESTCLASSとして実行すると、初期化エラーが発生します。私はそれが助けば日食で働き、私はJunitをプロジェクトの図書館に入れます。
音がクラスパスの問題のようです。 –
junit.rarをクラスパス – user1088557
に追加します。それでは問題は何ですか？ –
