OK.

No need for eval here

array = new window[arrayType](arrayValues.length);

[do-not-use, 2013/07/25 08:01:26]

Ok.

Shall we also test Uint8ClampedArray?

[arv (Not doing code reviews), 2013/07/24 16:38:13]

Change this to pass the constructors instead of the strings?

var arrayTypes = [Array, Int8Array, Int16Array, ...]

[do-not-use, 2013/07/25 08:01:26]

Good idea.

[do-not-use, 2013/07/25 08:01:26]

OK.

+for (var i = 0; i < arrayTypes.length; ++i) {
+    debug("* Test passing a " + arrayTypes[i] + " as input.");

[arv (Not doing code reviews), 2013/07/24 16:38:13]

then do arrayType[i].name

[do-not-use, 2013/07/25 08:01:26]

OK.

+    checkLineDash(createTestArray(arrayTypes[i]));
