required inject

use @required decorator to indicate framework MUST inject some values.

it('should throw error when can not provide value for @required value', async () => {

  const ic = InjectContainer.New();

  class A {
    @required
    @inject("v")
    aV: string;
  }

  class B {
    constructor(@required @inject("v") bV?) { }
  }

  class C {
    run(@required @inject("v") cV: any) {
      return cV;
    }
  }

  class D {
    static run(@required @inject("v") dV: any) { }
  }

  expect(() => ic.getInstance(A)).rejects.toThrow(RequiredNotFoundError);
  expect(() => ic.getInstance(B)).rejects.toThrow(RequiredNotFoundError);
  expect(async () => { const c = await ic.getWrappedInstance(C); return c.run(); }).rejects.toThrow(RequiredNotFoundError);
  expect(async () => { const d = await ic.wrap(D); return d.run(); }).rejects.toThrow(RequiredNotFoundError);

});
