This is my first kata.(experimental..)
Don't take this kata seriously.

When I am testing my program, it is saying "You have passed all of the tests! :)!"..
But when I attempt,I get this error.!!!! (In Java)

./src/test/java/CalculatorTest.java:11: error: reference to assertEquals is ambiguous
assertEquals("simple literal", d, Calculator.evaluate(d.toString()));
^
both method assertEquals(String,double,double) in Assert and method assertEquals(String,Object,Object) in Assert match
./src/test/java/CalculatorTest.java:19: error: reference to assertEquals is ambiguous

What is Happening and what should I do?
