dtype/test.js

Return a data type from a string representing the type

var test = require('tape')
var dtype = require('./')

test('dtype', function(t) {
  t.plan(11)
  var arr = new (dtype('int8'))
  t.ok(arr instanceof Int8Array)
  arr = new (dtype('int16'))
  t.ok(arr instanceof Int16Array)
  arr = new (dtype('int32'))
  t.ok(arr instanceof Int32Array)
  arr = new (dtype('uint8'))
  t.ok(arr instanceof Uint8Array)
  arr = new (dtype('uint16'))
  t.ok(arr instanceof Uint16Array)
  arr = new (dtype('uint32'))
  t.ok(arr instanceof Uint32Array)
  arr = new (dtype('float32'))
  t.ok(arr instanceof Float32Array)
  arr = new (dtype('float64'))
  t.ok(arr instanceof Float64Array)
  arr = new (dtype('array'))
  t.ok(arr instanceof Array)
  arr = new (dtype('uint8_clamped'))
  t.ok(arr instanceof Uint8ClampedArray)
  t.equal(dtype('buffer'), undefined, 'returns undefined for non-array types')
