This is a fork of AssertTest for three change:
- use the "enable_type_checks" flag (as per spec)
- check for AssertionError instead of AssertError (as per spec)
- removes checks for un-spec'd fields on AssertionError.

Should the other test remain then if it doesn't correspond to the spec?

[ahe, 2011/10/13 21:19:41]

If this is a fork, why is there no version history to indicate this?

[John Lenz, 2011/10/13 21:35:43]

That is what I want Peter to tell me.  Is the original test wrong or is the
spec?

[John Lenz, 2011/10/13 21:35:43]

I will correct this (svn cp are a pain to patch). I'm more intertested in the
basic question:
What is the correct exception to throw?
What is the correct flag to pass?
What fields are required on AssertError/AssertionError (not that I'll be adding
them in this change).

[John Lenz, 2011/10/13 21:51:08]

In case you were waiting for the "svn cp" to be done. Done.

AssertionError according to the specification.
I personally think it is bad form to use VM options in this case. I much more
prefer the multi-tests that are used in, for example, ClassLiteralTest.dart.
That is a library issue. According to Nicolas, it was a mistake to move
AssertTest.dart from the runtime to language.

great, I'll check this in then.
I'll leave that for a general clean up.
ok
