enzyme: Can't assert that methods are being called

Describe the bug

I’m trying to check if two methods are being called from componentDidMount. The first method gets called and it’s successful, but the second one fails. If I try testing just the second method it fails as well. I have to mention that I’m not using arrow functions and I’m binding in the constructor.

The following is an example of the test I wrote

it("calls handleAlertsRefetch and handleRefetch on mount", () => {
      const handleAlertsRefetch = jest.spyOn(
        Component.prototype,
        "handleAlertsRefetch"
      );
      const handleRefetch = jest.spyOn(
         Component.prototype,
         "handleRefetch"
      );
      const wrapper = createContext(BottomOverview, props);

      expect(handleAlertsRefetch).toHaveBeenCalled();
      expect(handleRefetch).toHaveBeenCalled();
    });

The createContext is a method that puts the component in an Apollo and react-router context:

export const createContext = (Component, props) => {
  Component.contextTypes = {
    router: PropTypes.object
  };
  const context = createRouterContext();
  const childContextTypes = {
    router: PropTypes.object
  };
  const wrapper = mount(
    <MockedProvider>
      <Component {...props} />
    </MockedProvider>,
    {
      context,
      childContextTypes
    }
  );
  return wrapper;
};

Expected behavior Both methods should be called and tests should be pass.

Additional context I use React 16 with the CRA boilerplate.
