I'm writing tests that use a variety of different commands and need to assert that they all fail with a particular code. However, the experience is extremely frustrating because the existing assert helpers all require a particular response format, and can't be used uniformly throughout:

• Error responses with a code field are caught by assert.commandWorked()
• Error responses with writeError are caught by assert.writeError()
• I have no idea if anyone can handle the plural writeErrors generated when using the bulk API
• Any other error response format I'm missing?

I would be very happy if we had one magic function that just "did the right thing" based on the response type / format.
