Shallow rendered components can't use useContext

[clottman]

Current behavior

The only way to test a component that relies on a useContext hook appears to be to use render or mount, not shallow.

The following methods of attempting to provide context to a component that is shallow rendered all fail:
See Code Sandbox with full details, including implementations of Child and TestContextHelper

    it("receives context when context is provided by a context helper component", () => {
      const wrapper = shallow(<Child />, {
        wrappingComponent: TestContextHelper
      });
      expect(wrapper.exists());
      expect(wrapper.text().includes("hi there")).toBe(true);
    });

    it("can be provided a context provider via wrappingComponent and wrappingComponentProps", () => {
      const wrapper = shallow(<Child />, {
        wrappingComponent: TestContext.Provider,
        wrappingComponentProps: { value: "hi there" }
      });
      expect(wrapper.text().includes("hi there")).toBe(true);
    });

    it("can be provided a context provider via wrappingComponent and setting props later", () => {
      const wrapper = shallow(<Child />, {
        wrappingComponent: TestContext.Provider
      });
      const provider = wrapper.getWrappingComponent();
      provider.setProps({ value: "hi there" });

      expect(wrapper.text().includes("hi there")).toBe(true);
    });

    it("can be wrapped by context and shallow rendered", () => {
      const wrapper = shallow(
        <TestContext.Provider value="hi there">
          <Child />
        </TestContext.Provider>
      );
      expect(wrapper.text().includes("hi there")).toBe(true);
    });
  });

Expected behavior

I can use shallow on components that use useContext
