Et1 Test Harness: Auto-Complete Input

• Tests where the prefix tree is created on the client (at page-load):
  • Note: The test is sensitive to network bandwidth.
  • Big Test
    • 42,910 completions
    • Data is loaded as a flat array from server.
    • This test has a button to test deallocation (freeing for garbage collection) and reallocation of the memory used by the tree.
    • Do not try this on IE 6 or IE 7 unless you have a fast (2gHz Intel) and high-memory (2 GB+) machine.
  • Small Test
    • 1,195 completions
    • Data is loaded as a flat array from server.

• For testing purposes, pre-prepared prefix trees may be compared to those created on the fly. Initial tests indicate that time-to-page-ready is less when the tree is created on the client rather than downloaded as a prepared tree in a JavaScript include file. This appears to be due to the great expansion needed to create the tree in JSON format. Here are tests where the prefix tree is pre-prepared (downloaded already set up):

  • Notes
    • The prepared trees are very large (1.2 MB for the large-size test) and so are very sensitive to network bandwidth.
    • The prefix trees were created using the Prefix Tree Generator
  • Big Tree Test
    • 42,910 completions
    • Data is loaded from server as a complete prefix tree in object literal JSON notation.
    • Do not try this on IE 6 or IE 7!
  • Small Tree Test
    • 1,195 completions
    • Data is loaded from server as a complete prefix tree in object literal JSON notation.
