JUnit testing with multiple test cases in a method
I have a following class A with a constructor that takes two strings as parameters.
Class A
{
String test1;
String test2;
public(String test1, String test2)
{
this.test1 = test1;
this.test2 = test2;
}
}
I would like to test a constructor with three test cases within a one test case method ie 1. Null test1 2. Null test2 3. Null test1, Null test2
String test1 = "ABC";
String test2 = "XYZ";
@Test(expected=NullPointerException.class)
public void testNullConstructorValues() {
new A(null, test2);
new A(test1, null);
new A(null, null);
}
The problem here is that after first constructor declaration, the method throws NPE and returns out of the method. I would like the method to execute all 3 constructor declarations within just one method and perform the expected exception check.
Is there any way to do this of doing all 3 test cases within one method?
使用参数化亚军测试。
@RunWith(Parameterized.class)
public class ATest {
private String value1;
private String value2;
private static final String ABC = "abc";
private static final String XYZ = "xyz";
public ATest(String value1, String value2) {
this.value1 = value1;
this.value2 = value2;
}
@Test(expected=NullPointerException.class)
public void nullPassedToConstructor() {
A a = new A(value1, value2);
}
// Provide data
@Parameters
public static List<Object[]> data() {
List<Object[]> list = new ArrayList<Object[]>();
list.add(new Object[] {null, XYZ});
list.add(new Object[] {ABC, null});
list.add(new Object[] {null, null});
return list;
}
}
