Java – JUnit asserts double arrays

How do I assert that two double arrays contain the same elements There are some ways to assert that integer arrays and other basic types contain the same elements, but do not contain doubles

Solution

If you are not using a version of JUnit that supports double array comparison, the simplest solution is to use arrays equals：

assertTrue(Arrays.equals(array1,array2));

However, this cannot deal with the rounding error made by JUnit's double assertion
