I should add a line that ensures db.version is a string and not an integer.

[jsbell, 2012/08/04 03:42:30]

Agreed!

[dgrogan, 2012/08/07 22:13:20]

Done.

This is to ensure that the test leveldb files were used, right? Can you add a
comment?

I can imagine in the future that we change the path used so that it isn't
"file__0.indexeddb.leveldb" so the test data isn't present and the open succeeds
but opens an empty database. Someone reading this test might not know what the
length != 1 implies without a lot of digging.

Done.
