# mochawesome
[](http://www.npmjs.com/package/mochawesome)  [](https://gitter.im/mochawesome/general)
Mochawesome is a custom reporter for use with the Javascript testing framework, [mocha][mocha]. It runs on Node.js (>=10) and works in conjunction with [mochawesome-report-generator][marge] to generate a standalone HTML/CSS report to help visualize your test runs.
## Features
- 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
- Supports `parallel` mode
## Usage
1. Add Mochawesome to your project:
`npm install --save-dev mochawesome`
2. Tell mocha to use the Mochawesome reporter:
`mocha testfile.js --reporter mochawesome`
3. If using mocha programatically:
```js
var mocha = new Mocha({
reporter: 'mochawesome',
});
```
### Parallel Mode
Since `mocha@8` test files can be run in parallel using the `--parallel` flag. In order for mochawesome to work properly it needs to be registered as a hook.
`mocha tests --reporter mochawesome --require mochawesome/register`
### Output
Mochawesome generates the following inside your project directory:
```
mochawesome-report/
├── assets
│ ├── app.css
│ ├── app.js
│ ├── MaterialIcons-Regular.woff
│ ├── MaterialIcons-Regular.woff2
│ ├── roboto-light-webfont.woff
│ ├── roboto-light-webfont.woff2
│ ├── roboto-medium-webfont.woff
│ ├── roboto-medium-webfont.woff2
│ ├── roboto-regular-webfont.woff
│ └── roboto-regular-webfont.woff2
├── mochawesome.html
└── mochawesome.json
```
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
Options can be passed to the reporter in two ways.
#### Environment variables
The reporter will try to read environment variables that begin with `MOCHAWESOME_`.
```bash
$ export MOCHAWESOME_REPORTFILENAME=customReportFilename
```
_Note that environment variables must be in uppercase._
#### Mocha reporter-options
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.
```bash
$ mocha test.js --reporter mochawesome --reporter-options reportDir=customReportDir,reportFilename=customReportFilename
```
Alternately, `reporter-options` can be passed in programatically:
```js
var mocha = new Mocha({
reporter: 'mochawesome',
reporterOptions: {
reportFilename: 'customReportFilename',
quiet: true,
},
});
```
#### Available Options
The options below are specific to the reporter. For a list of all available options see [mochawesome-report-generator options][marge-options].
| Option Name | Type | Default | Description |
| :---------------- | :------ | :---------- | :-------------------------------------------------------------------------------------------------------------------------------- |
| `quiet` | boolean | false | Silence console messages |
| `reportFilename` | string | mochawesome | Filename of saved report (html and json)
_See [notes](#reportfilename-replacement-tokens) for available token replacements._ |
| `html` | boolean | true | Save the HTML output for the test run |
| `json` | boolean | true | Save the JSON output for the test run |
| `consoleReporter` | string | spec | Name of mocha reporter to use for console output, or `none` to disable console report output entirely |
#### reportFilename replacement tokens
Using the following tokens it is possible to dynamically alter the filename of the generated report.
- **[name]** will be replaced with the spec filename when possible.
- **[status]** will be replaced with the status (pass/fail) of the test run.
- **[datetime]** will be replaced with a timestamp. The format can be - specified using the `timestamp` option.
For example, given the spec `cypress/integration/sample.spec.js` and the following config:
```
{
reporter: "mochawesome",
reporterOptions: {
reportFilename: "[status]_[datetime]-[name]-report",
timestamp: "longDate"
}
}
```
The resulting report file will be named `pass_February_23_2022-sample-report.html`
**Note:** The `[name]` replacement only occurs when mocha is running one spec file per process and outputting a separate report for each spec. The most common use-case is with Cypress.
### Adding Test Context
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](#example).
### `addContext(testObj, context)`
| 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:
```js
{
title: 'some title'; // must be a string
value: {
} // can be anything
}
```
#### Example
Be sure to use ES5 functions and not ES6 arrow functions when using `addContext` to ensure `this` references the test object.
```js
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.
```js
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
});
});
```
## Typescript
This project does not maintain its own type definitions, however they are available on npm from [DefinitelyTyped](https://github.com/DefinitelyTyped/DefinitelyTyped/tree/master/types/mochawesome).
```
$ npm install --save-dev @types/mochawesome
```
