Description

In https://github.com/mongodb/specifications/blob/master/source/bson-corpus/tests/code.json starting with the fourth test (line 21 and following), the tests switch from correctly testing BSON type 0x0D (JavaScript code) to incorrectly testing BSON type 0x02 (regular strings).

Unfortunately, the comparison canonical_extjson seems to have been generated from the BSON, meaning that the tests succeed for the wrong reason -- they are regular string tests, not code tests.

Likewise, all of the decodeErrors tests are for regular strings, not code, despite the descriptions.

Research direction

Open source/bson-corpus/tests/code.json and inspect the fourth test onward, including the decodeErrors cases. Compare the BSON type and canonical_extjson values with the descriptions and the earlier code tests. Done means the fixtures exercise BSON type 0x0D JavaScript code rather than type 0x02 strings, with the decode-error cases matching that type.
