The kata's testing code incorrectly assumes that there is only 1 possible row/column/diagonal sum for every magic square of a certain size. In fact this is already untrue for 4x4 magic squares.

Its calculation is also flawed: adding a constant to all numbers will result in the "expected sum" to change by a different amount. Any minimum value other than 0 will cause the sum test to fail.

This kata cannot be solved:

ReferenceError: Test is not defined
    at verify (test.js:33:13)
    at Context.<anonymous> (test.js:63:17)
    at processImmediate (internal/timers.js:464:21)

Seems like it does not work... at least.. for valid 3x3 square i got response:
The sum in row 0 is incorrect.: expected 15 to equal 13.5
