@RunWith(Parameterized.class)
but either do not include a data provider method annotated with @Parameterized.Parameters
or
this method has an incorrect signature. Such test classes cannot be run.
The data provider method should be public
and static
and have a return type of Iterable
or
Object[]
.
Suggests creating an empty parameter provider method or changing the signature of the incorrect data provider method.
Example:
@RunWith(Parameterized.class)
public class ImportantTest {
private int input;
private int expected;
ImportantTest(int input, int expected) {
this.input = input;
this.expected = expected;
}
// ... test cases
}
After the quick-fix is applied:
@RunWith(Parameterized.class)
public class ImportantTest {
private int input;
private int expected;
ImportantTest(int input, int expected) {
this.input = input;
this.expected = expected;
}
@Parameters
public static Iterable<Object[]> parameters() {
return null;
}
// ... test cases
}
