jest-search

Node.js CI .github/workflows/release.yml Known Vulnerabilities codecov npm version License: MIT

Jest preset for running tests with local ElasticSearch, OpenSearch and ZincSearch.

Usage

Prerequisite:

ElasticSearch and OpenSearch relies on Java, please make sure you have Java installed and JAVA_HOME is set.

jest-search provide two ways to set up, one is two set up globally, another is running in specific test only

set up globally

1. install library

npm install --save-dev @geek-fun/jest-search

2. create config file jest-search-config.js

all configuration items are optional, but it still requires you to module. exports the function in jest-search-config.js, there aren't any indexes created without passing the indexes configuration,

module.exports = () => {
  return {
    engine: 'elasticsearch', // or 'opensearch' or 'zincsearch'
    version: '8.8.2',
    port: 9200,
    binaryLocation: '', // optional
    clusterName: 'jest-search-local',
    nodeName: 'jest-search-local',
    zincAdmin: 'admin',
    zincPassword: 'Complexpass#123',
    indexes: [
      {
        name: 'index-name',
        body: {
          settings: {
            number_of_shards: '1',
            number_of_replicas: '1'
          },
          aliases: {
            'your-alias': {}
          },
          mappings: {
            dynamic: false,
            properties: {
              id: {
                type: 'keyword'
              }
            }
          }
        }
      }
    ]
  };
};
  • engine: specify startup search engine platform

    allowed value: elasticsearch, opensearch, zincsearch

    default: elasticsearch

  • version: specify startup search engine version

    allowed value: check the versions in each platform's release page

    default: 8.8.2

  • port: specify startup search engine port number

    allowed value: 1024 ~ 2147483647

    default: 9200

  • binaryLocation: use downloaded engine instead default: undefined

  • clusterName: engine's clusterName default: jest-search-local

  • nodeName: engine's nodeName default: jest-search-local

  • indexes: specify the configuration like index name, and mapping of indexes that you want to create during the startup, and indexes will get deleted once test is finished: default: []

  • zincAdmin: zincsearch requires pass env ZINC_FIRST_ADMIN_USER when starting zincsearch, default: admin,

  • zincPassword: : zincsearch requires pass env ZINC_FIRST_ADMIN_PASSWORD when starting zincsearch, default: Complexpass#123

3. create jest-global-setup.js

const { globalSetup } = require('@geek-fun/jest-search');
module.exports = async () => {
  await Promise.all([globalSetup()]);
};

4. create jest-global-teardown.js

const { globalTeardown } = require('@geek-fun/jest-search');
module.exports = async () => {
  await Promise.all([globalTeardown()]);
};

4. modify the jest-config.js

module.exports = {
	...
  globalSetup: '<rootDir>/jest-global-setup.js',
  globalTeardown: '<rootDir>/jest-global-teardown.js',
};

3. play with your tests

// tests/utils/helper.ts sample utils to add item for test
export const saveBook = async (bookDoc: { name: string; author: string }) => {
  await esClient.index({ index, body: bookDoc, refresh: true });
};

// tests/book.test.ts sample test
beforeAll(async () => {
  await saveBook(mockBook);
});

specific test only

the step 1 and 2 are the same as above, jest-search export two methods startEngine and stopEngine to start and stop the search engine, you can manually call them in your test file, the startEngine accepts same argument object as defined in jest-search-config.js file

import { startEngine, stopEngine } from '@geek-fun/jest-search';
// eslint-disable-next-line @typescript-eslint/ban-ts-comment
// @ts-ignore
import loadConfig from '../jest-search-config.js';


describe('integration test for elasticsearch', () => {
  beforeAll(async () => {
    await startEngine(loadConfig());
    await saveBook(mockBook);
  });
  afterAll(async () => {
    await stopEngine();
  });
  it('should get book when search with valid book name', async () => {
    // ...
  });
});

  1. Windows is not on the support list yet, I didn't see the necessity of it yet, feel free to reach out if you have the needs to use it on Windows, then will prioritize it
