Installation


  npm install jest-html-reporters --save-dev

Usage


Configure Jest to process the test results by adding the following entry to the Jest config (jest.config.json):

"jest": {
  ...,
  "reporters": [
    "default",
    "jest-html-reporters"
  ],
  ...
}

As you run Jest from within the terminal, a file called jest_html_reporters.html will be created within your root folder containing information about your tests.

2.x updates

  • Collapsable Test Groups

This feature regrading to #37, if a test file has many test cases, here will show a Merge Data checkbox on the expanded table. You can check it to merge data and set the merge level to control how to combine those data.

For Example merge data example

  • Attach screenshot to report

This feature regrading to #36, this package will a new method named addAttach.

/**
 *
 * @param {Buffer | string} attach
 * @param {string} description of the picture
 * @param {object} custom context (optional)
 */
const addAttach = async (attach, description, context) => { ... }

There are three params of this method, description is easy to understand. The param attach referring to the image, you can pass a buffer or string, if it was a buffer the package will help you create a dir named jest-html-reporters-attach and save that buffer as a jpg image in it under the publicPath. if you have already saved the image, just pass the image's path as the attach param. context is an optional parameter. Here can be specified context (default is this.global).

Here is an Example with puppeteer.

// Example attach with **buffer**
const { addAttach } = require("jest-html-reporters/helper");
const puppeteer = require("puppeteer");

describe("just examples", () => {
  test("test buffer", async () => {
    const browser = await puppeteer.launch();
    const page = await browser.newPage();
    await page.goto("https://www.google.com");
    const data = await page.screenshot();
    await browser.close();
    await addAttach(data, "test google 1", this.global);

    expect(1).toBe(1);
  });
});
// Example attach with **string**
const { addAttach } = require("jest-html-reporters/helper");
const puppeteer = require("puppeteer");
const path = require("path");

describe("just examples", () => {
  test("case string", async () => {
    const browser = await puppeteer.launch();
    const page = await browser.newPage();
    const filePath = path.resolve(__dirname, "./test.jpg");
    await page.goto("https://www.google.com");
    const data = await page.screenshot({ path: filePath });
    await browser.close();
    await addAttach(filePath, "test google 2");

    expect(1).toBe(2);
  });
});

it will show like this example

  • Attach a message to the report

This feature is in regards to #63 & #64. It allows you to add a message or log something to the html report with addMsg()

/**
 *
 * @param {string} message
 * @param {object} custom context (optional)
 */
const addMsg = async (message, context) => { ... }

Only one parameter is required. If you stringify an object like this JSON.stringify(object, null, 2), the object will be prettified. context is an optional parameter. Here can be specified context (default is this.global).

Here is an Example with Nightmare.

const { addAttach, addMsg } = require("jest-html-reporters/helper");
const Nightmare = require("nightmare");

describe("Yet another example", () => {
  test("Both addAttach & addMsg with failure", async () => {
    const nightmare = Nightmare({ show: true });
    await addMsg(JSON.stringify({ won: 1, too: 2 }, null, 2));
    await nightmare.goto("https://duckduckgo.com");
    const s1 = await nightmare.screenshot();
    await addAttach(s1, "test duckduckgo 1");
    await nightmare.end();
    await addMsg(JSON.stringify(process, null, 2));
    expect(2).toEqual(1);
  }, 20000);
  test("addMsg with success", async () => {
    await addMsg(JSON.stringify({ free: 3, for: 4 }, null, 2));
    expect(2).toEqual(2);
  });
});

example

Message still displays without screenshots and with a successful test example
