  - ### Method Detail

    - #### convertToRelative

          public static String convertToRelative(Class clazz,
                                                 File f)

    - #### assumeNonDeterministic

          public static void assumeNonDeterministic()

      Used at the start of a test to make it one that should only be executed when the `assertNonDeterministic` system property is set to `true`. Tests that call this method are ones that may sometimes fail in certain environments or behave in other random ways. Usually such tests should be removed or re-worked, but there are situations where that may not be possible as there is no other good way to test the feature. In these cases, the tests won't fail a standard build. For this benefit, the downside is that the feature isn't tested as often as it would otherwise, since the `assertNonDeterministic` option is not used often and definitely not in automated builds like Travis.

          public static void validateVertexEquality(Vertex originalVertex,

    - #### validateVertexPropertyEquality

          public static void validateVertexPropertyEquality(VertexProperty originalVertexProperty,
