java123999 :
I am getting the following error:
Both assertEquals(Object, Object) in Assert and assertEquals(double, double) in Assert match
For this line of code in my Junit
tests, note that getScore
() returns a double
:
assertEquals(2.5, person.getScore());
This is my assert import:
import static org.junit.Assert.*;
What is causing this and how can I fix this?
Bechyňák Petr :
I guess your getScore() returns Double, not double. Therefore compiler is confused: Should he convert both arguments to Object, or should he convert only the Double to double?
double a = 2.0;
Double b = 2.0;
// assertEquals(a,b); // fails to compile
// the compiler is confused whether to use
assertEquals((Object) a,(Object) b); // OK
// or
assertEquals(a,(double) b); // OK
Anyway, I would set the method to return primitive type double.
