What are jest-html-reporter's main functionalities?

Basic HTML Report

This configuration generates a basic HTML report with a custom page title. It is added to the Jest configuration file (jest.config.js or package.json).

{
  "reporters": [
    "default",
    [
      "jest-html-reporter",
      {
        "pageTitle": "Test Report"
      }
    ]
  ]
}

Custom Output Path

This configuration specifies a custom output path for the HTML report. The report will be saved to the specified location.

{
  "reporters": [
    "default",
    [
      "jest-html-reporter",
      {
        "outputPath": "./reports/test-report.html"
      }
    ]
  ]
}

Custom Report Title and Theme

This configuration allows setting a custom title and theme for the HTML report. The 'darkTheme' option provides a dark-themed report.

{
  "reporters": [
    "default",
    [
      "jest-html-reporter",
      {
        "pageTitle": "My Custom Test Report",
        "theme": "darkTheme"
      }
    ]
  ]
}

Include Failure Messages

This configuration includes detailed failure messages in the HTML report, making it easier to debug test failures.

  "reporters": [
    "default",
    [
      "jest-html-reporter",
      {
        "includeFailureMsg": true
      }
    ]
  ]
}

Sort Results

This configuration sorts the test results in the HTML report by status, making it easier to identify failed tests.

{
  "reporters": [
    "default",
    [
      "jest-html-reporter",
      {

README

jest-html-reporter

A jest test results processor for generating a summary in HTML.

This plugin was inspired by karma-htmlfile-reporter

Installation

npm install jest-html-reporter

Usage

You must configure jest to process the test results by adding the following entry to the jest config:

{
	"testResultsProcessor": "./node_modules/jest-html-reporter"
}

Then when you run jest from within the terminal, a file called test-report.html will be created within your root folder containing general information about your tests.

Configuration

The configurations are done directly within your package.json file

pageTitle (string)

[Default: "Test Suite"]

The title of the document. This string will also be outputted on the top of the page.

outputPath (string)

[Default: "./test-report.html"]

The path to where the plugin will output the HTML report. The path must include the filename and end with .html

includeFailureMsg (boolean)

[Default: false]

If this setting is set to true, this will output the detailed failure message for each failed test.

styleOverridePath (string)

[Default: null]

The path to a file containing CSS styles that will override the default styling of the report. The plugin will search for the file from the root directory, therefore there is no need to prepend the string with ./ or ../

Please refer to the file named style.js within the root folder of this plugin for an example of the IDs and classes that are available for styling.

Example configuration (package.json)

	...

		"pageTitle": "Your test suite",
		"outputPath": "test-report/index.html",
