Use Enzyme to test React/Redux container - dive

ShowBox.jsx

describe('ConnectedShowBox', () => {
  it("should render a text box with empty string inside if string is not provided by store", () => {
    const testState = {
      searchBox: {}
    };
    const store = createMockStore(testState)
    const component = shallowWithStore(<ConnectedShowBox />, store);
    expect(component).to.be.a('object');
    expect(component.dive().find("").prop("value")).to.equal("")
  });
});
