Summary

The handshake spec requires that all strings provided as part of the driver info MUST NOT contain the delimiter used for metadata concatenation, and that drivers MUST throw an error if any of these strings contains that character. There are currently no tests for this requirement. For example, in the Go driver the following test will fail:

func TestMGC_Client_SetDriverInfoWithDelimeter(t *testing.T) {
	opts := options.Client().SetDriverInfo(&options.DriverInfo{
		Name:     "has|pipe",
		Version:  "1|2",
		Platform: "p|q",
	})

	client, err := mongo.Connect(opts)
	defer func() { _ = client.Disconnect(context.Background()) }()

	require.Error(t, err)
}

Is this issue urgent?

No

Is this ticket required by a downstream team?

No

Is this ticket only for tests?

Yes

Acceptance Criteria

Create a test that asserts an error when name, version, or platform contains the delimiter.
