Error: Module not found: Error: Can't resolve 'fs'

[mourav2222]

I use allure jasmine adapter in angular tests. Why command

import { readFileSync } from "fs"; in 
/node_modules/allure-js-commons/dist/esm/src/current/writers/FileSystemAllureWriter.js:1:0-72

can't be executed?

i configured like in the description https://allurereport.org/docs/jasmine/

adapter in helpers/setup.ts added

import { JasmineAllureReporter } from "allure-jasmine";
import { Status, TestResult } from "allure-js-commons";
import * as os from "os";

const reporter = new JasmineAllureReporter({
  resultsDir: "./allure-results",
  testMapper: (result: TestResult) => {
    if (result.status == Status.SKIPPED) {
      result.fullName = `(WAS SKIPPED) ${result.fullName}`;
    }
    return result;
  },
});

jasmine.getEnv().addReporter(reporter);
export const allure = reporter.getInterface();

allure.writeEnvironmentInfo({
  os_platform: os.platform(),
  os_release: os.release(),
  os_version: os.version(),
  node_version: process.version,
});

allure.writeCategoriesDefinitions([
  {
    name: "Sad tests",
    messageRegex: /.*Sad.*/,
    matchedStatuses: [Status.FAILED],
  },
  {
    name: "Infrastructure problems",
    messageRegex: ".*RuntimeException.*",
    matchedStatuses: [Status.BROKEN],
  },
  {
    name: "Outdated tests",
    messageRegex: ".*FileNotFound.*",
    matchedStatuses: [Status.BROKEN],
  },
  {
    name: "Regression",
    messageRegex: ".*\\sException:.*",
    matchedStatuses: [Status.BROKEN],
  },
]);

test:

import { SimpleService } from "./simple.service"
import { allure } from "../../helpers/setup";

let service: SimpleService;

describe('should create Simple service', () => {

    beforeEach( () => {
        service = new SimpleService();
    });

    it('should create Simple service-002', () => {
        
        allure.description('Test1: should create Simple service');
       expect(service).toBeTruthy();
    
    });

Hey!

Your tests run in a browser environment where the node standard library is not available.

I can propose you to try to follow the recommendation from the prompt you attached. Currently, I don't know how looks communication between karma and jasmine in case of angular testing and what kind of reporter we can use there.

Thx. I soled it with karma allure module how here https://github.com/allure-framework/allure-karma

[dasco144]

@mourav2222 is there anything specific you did to get these allure-js-commons imports working in a Karma runner? We have an Angular repo and we're facing the same issue.

[mourav2222]

@dasco144 No, i didn't solve with allure jasmine in angular 17. I sent other question in hope, somebody will help me. https://github.com/orgs/allure-framework/discussions/2575

[dasco144]

Thanks, Mike. I'll follow that thread as well.

There must be some way to get this working, as I see the karma plugin imports from allure-js-commons. I see when the tests run that there is a window.allure object, but I'm not sure it exposes all that allure-js-commons provides.
