sandbox.replaceSetter();

Replaces setter for property on object with replacement argument. Attempting to replace an already replaced setter causes an exception.

replacement must be a Function, and can be instances of fake, spy and stub.

  };

  sinon.replaceSetter(object, "myProperty", function (value) {
    this.prop = "strawberry " + value;
  });

  object.myProperty = "pie";

  t.equal(object.prop, "strawberry pie", "setter replaced and called");

  sinon.restore();

  t.end();
