Drivers use the failCommand fail point extensively in spec tests. It seems that with each server release we need to add a new knob to this fail point in order to test new features. In 4.0 we added the "writeConcernError" field (SERVER-35083). In 4.4 we're adding the "errorLabels" field (SERVER-43941).
It might be useful to add a way for the command to specify the entire error document to return instead of just the error code or the errorLabels. For example:
db.adminCommand({
configureFailPoint: "failCommand",
mode: "alwaysOn",
data: {failCommands: ["find"], errorDoc: {ok: 0, code: 2, errmsg: "my error message", errorLabels: ["Label"]}}
});
// Returns {ok: 0, code: 2, errmsg: "my error message", errorLabels: ["Label"]}
db.runCommand({find: "collection"});
db.adminCommand({configureFailPoint: "failCommand", mode: "off"});
This would also satisfy SERVER-42239 since the user could add "extraInfo" to the errorDoc.
