why does junit4 not have Assert.assertArrayEquals() for double[]s?

There appear to be Assert.assertArrayEquals() methods in Junit4 for all primitives other than double, e.g.

Assert.assertArrayEquals(int[] expected, int[] actual)

and

Assert.assertArrayEquals(char[] expected, char[] actual)

but not 

Assert.assertArrayEquals(double[] expected, double[] actual, double eps)

or

Assert.assertArrayEquals(double[] expected, double[] actual, double[] eps)

(the latter to account for variable ranges of doubles). Is there a fundamental reason why I should not write such a function?

Solution

  • It does have such a method (in 4.7), although it is not documented on the online javadoc here. It was certainly an oversight in the javadoc/version, but it is there now.
