const handleSubmit = sinon.spy();
const wrapper = mount(
  <Provider store={store}>
    <MyForm onSubmit={handleSubmit} />
  </Provider>
);

// Assume MyForm having a platform select input whose name is "platform"
const elem = wrapper.find("Select[name='platform']");
elem.prop("onChange")("iOS");  // Get onChange and call directly instead of the traditional elem.simulate("change", {target: {value: "iOS"}}) for <select> or <input>

expect(handleSubmit.getCall(0).args[0]).toMatchObject({ platform: "iOS" });
