Simple and complete Reblendjs testing utilities that encourage good testing practices.

import { Reblend } from "reblendjs";
import { render } from "../";
test("render errors", async () => {
  //@reblendComponent
  class Thrower extends Reblend {
    static ELEMENT_NAME = "Thrower";
    constructor() {
      super();
    }
    async initState() {
      throw new Error("Boom!");
    }
    async initProps() {
      this.props = {};
    }
    async html() {
      return;
    }
  }
  /* @Reblend: Transformed from function to class */
  let errorMessage = "";
  class ErrorBoundary extends Reblend {
    handleError(error) {
      errorMessage = error.message;
    }
  }
  await render(Reblend.construct.bind(this)(Thrower, null), {
    wrapper: ErrorBoundary
  });
  expect(errorMessage).toBe("Boom!");
});
