I have a question about JUnit assertEquals to test double values. Reading the API doc I can see:
@Deprecated public static void assertEquals(double expected, double actual)Deprecated. Use
assertEquals(double expected, double actual, double delta)instead.
(Note: in older documentation versions, the delta parameter is called epsilon)
What does the delta (or epsilon) parameter mean?
Epsilon is the value that the 2 numbers can be off by. So it will assert to true as long as
Math.abs(expected - actual) <= epsilon
