Status of underscore testcases
Overview
Underscore testcases exercise some core language features but also contain some browser specific stuff. There are also some asynchronous tests which cannot be executed directly. Underscore uses a unit test framework which needs to be emulated, see underscore-test-shim.js.
This document summarizes the currently failing testcases and why they fail.
Summary of failure reasons
- Because asyncTest() is unimplemented, all async tests are skipped now (such tests are used in the Functions module).
- Several template testcases fail (see below), not diagnosed yet. The same errors occur with Rhino, so the culprit is probably the shim or the test cases themselves.
- Interpolate bug, see below.
