? Java Unit Test Error: Test class should has exactly one public Zero-argument constructor?

public class test{

Private String A;

private int B;

}

Public Test (String A, int b) {

THIS.A = A;

this.b = b;

}

public boolean T1 (String s) {

if (S.length ()) {

return true;

}else{

return false;

}

}

@Test

public void Test1 () {

Test T = new Test ("AAA", 5);

T.T1 ("123");

}

The running program appears:

Java.lang.Exception:

Test class should has exactly one public Zero-argument constructor

Cause: The class contains a parameter constructor. Workaround: Separate the class with the argument constructor.
