Restore single stub in sandbox

Question

sandbox = sinon.sandbox.create();

sandbox.stub(db, 'query', () => {
    return Promise.resolve();
});

sandbox.stub(process, 'exit', () => { });

sandbox.restore(); removes all the stubs.

I want to remove ONE stub so I can restub it. For example the query stub.

Is this possible? I can't find any information on this.

You can restore single method like this:

db.query.restore();

for your particular case.

Per sinon documentation:

var stub = sinon.stub(object, "method");

Replaces object.method with a stub function. An exception is thrown if the property is not already a function.

The original function can be restored by calling object.method.restore(); (or stub.restore();).

See http://sinonjs.org/releases/v2.3.6/stubs/
