Mochawesome is a custom reporter for use with the Javascript testing framework, mocha. It runs on Node.js (>=8) and works in conjunction with mochawesome-report-generator to generate a standalone HTML/CSS report to help visualize your test runs.
- Simple, clean, and modern design
- Beautiful charts (via ChartJS)
- Support for test and suite nesting
- Displays before and after hooks
- Review test code inline
- Stack trace for failed tests
- Support for adding context information to tests
- Filters to display only the tests you want
- Responsive and mobile-friendly
- Offline viewing
- Add Mochawesome to your project:
npm install --save-dev mochawesome
- Tell mocha to use the Mochawesome reporter:
mocha testfile.js --reporter mochawesome
- If using mocha programatically:
var mocha = new Mocha({
reporter: 'mochawesome'
});
Mochawesome generates the following inside your project directory:

The two main files to be aware of are:
mochawesome.html - The rendered report file
mochawesome.json - The raw json output used to render the report
Options can be passed to the reporter in two ways.
The reporter will try to read environment variables that begin with MOCHAWESOME_
.
$ export MOCHAWESOME_REPORTFILENAME=customReportFilename
Note that environment variables must be in uppercase.
You can pass comma-separated options to the reporter via mocha's --reporter-options
flag. Options passed this way will take precedence over environment variables.
$ mocha test.js --reporter mochawesome --reporter-options reportDir=customReportDir,reportFilename=customReportFilename
Alternately, reporter-options
can be passed in programatically:
var mocha = new Mocha({
reporter: 'mochawesome',
reporterOptions: {
reportFilename: 'customReportFilename',
quiet: true
}
});
The options below are specific to the reporter. For a list of all available options see mochawesome-report-generator options.
Option Name | Type | Default | Description |
---|---|---|---|
quiet |
boolean | false | Silence console messages |
reportFilename |
string | mochawesome | Filename of saved report Applies to the generated html and json files. |
html |
boolean | true | Save the HTML output for the test run |
json |
boolean | true | Save the JSON output for the test run |
Mochawesome ships with an addContext
helper method that can be used to associate additional information with a test. This information will then be displayed inside the report.
Please note: arrow functions will not work with addContext
. See the example.
param | type | description |
---|---|---|
testObj | object | The test object |
context | string|object | The context to be added to the test |
Context as a string
Simple strings will be displayed as is. If you pass a URL, the reporter will attempt to turn it into a link. If the URL links to an image or video, it will be shown inline.
Context as an object
Context passed as an object must adhere to the following shape:
{
title: 'some title' // must be a string
value: {} // can be anything
}
Be sure to use ES5 functions and not ES6 arrow functions when using addContext
to ensure this
references the test object.
const addContext = require('mochawesome/addContext');
describe('test suite', function () {
it('should add context', function () {
// context can be a simple string
addContext(this, 'simple string');
// context can be a url and the report will create a link
addContext(this, 'http://www.url.com/pathname');
// context can be an image url and the report will show it inline
addContext(this, 'http://www.url.com/screenshot-maybe.jpg');
// context can be an object with title and value properties
addContext(this, {
title: 'expected output',
value: {
a: 1,
b: '2',
c: 'd'
}
});
})
});
It is also possible to use addContext
from within a beforeEach
or afterEach
test hook.
describe('test suite', () => {
beforeEach(function () {
addContext(this, 'some context')
});
afterEach(function () {
addContext(this, {
title: 'afterEach context',
value: { a: 1 }
});
});
it('should display with beforeEach and afterEach context', () => {
// assert something
});
});
