The easiest way is to print the sum of squares and compare with other tools.

Since k-means heuristically minimizes this value, it should be close to the ideal value. If the value is much higher, there is a bug.

There is no "true" solution in clustering. It's successful, if you discovered new knowledge, not just because you optimized some statistic.
