Allure 2 Typescript step decorators

decorators.ts

import { allure } from "../conf/protractorConf"; // export AllureInterface from the config file with onPrepare etc.

export function step(description: string): (...args: any[]) => TypedPropertyDescriptor<any> {
  return (target: Object, key: string | symbol, descriptor: TypedPropertyDescriptor<any>): TypedPropertyDescriptor<any> => {
    const original = descriptor.value;
    descriptor.value = function(...args: any[]) {
      // todo you can inject args into the description here if needed
      return allure.step(description, () => {
        console.log(`Running step: ${description}`);
        return original.apply(this, args);
      });
    };
    return descriptor;
  };
}
  
// don't forget to set "compilerOptions": { "experimentalDecorators": true } in `tsconfig.json`

example.ts

import { step } from "decorators";

class Page {
  @step("Navigating to main page")
  public go() {
    return browser.get("http://example.com/");
