Running Jurassic against the test262 test suite (11/11/2011) produces the following results:
| Jurassic v2.1 Nightly (26/11/11) | Jurassic v2.1 Nightly on Windows Phone 7 (19/12/11) |
|---|---|
| Tests successful | 10,283 |
| Tests failed | 759 |
| Tests skipped | 79* |
| Total tests | 11,121 |
*test262 defines a list of tests to skip. Tests that are skipped are normally buggy or invalid in some way.
Failure areas:
- Jurassic currently doesn't support freezing or setting properties on array indices. This produces the majority of the errors.
- Jurassic leverages the regular expression engine built into .NET. This engine tends to be less forgiving of syntax errors then the ECMAScript standard requires and has a few edge cases that don't meet the spec.
