============================
[![npm](https://img.shields.io/npm/v/mochawesome-report-generator.svg)](http://www.npmjs.com/package/mochawesome-report-generator) ![Node CI](https://github.com/adamgruber/mochawesome-report-generator/workflows/Node%20CI/badge.svg)

**marge** (**m**och**a**wesome-**r**eport-**ge**nerator) is the counterpart to [mochawesome][2], a custom reporter for use with the Javascript testing framework, [mocha][1]. Marge takes the JSON output from [mochawesome][2] and generates a full fledged HTML/CSS report that helps visualize your test suites.

## Features

- Simple, clean, and modern design
- 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

- CLI for generating reports independent of [mochawesome][2]

## Usage with mochawesome

1. Add Mochawesome to your project:

  `npm install --save-dev mochawesome`

  ```js
  var mocha = new Mocha({
    reporter: 'mochawesome'
  });
  ```

## CLI Usage

Install mochawesome-report-generator package
```bash
npm install -g mochawesome-report-generator
```

Run the command
```bash
marge [options] data_file [data_file2 ...]
```

### CLI Flags

**marge** can be configured via the following command line flags:

Flag | Type | Default | Description 
:--- | :--- | :------ | :----------
-f, --reportFilename | string | mochawesome | Filename of saved report. *See [notes](#reportfilename-replacement-tokens) for available token replacements.*
-o, --reportDir | string | [cwd]/mochawesome-report | Path to save report
-t, --reportTitle | string | mochawesome | Report title
-p, --reportPageTitle | string | mochawesome-report | Browser title
-i, --inline | boolean | false | Inline report assets (scripts, styles)
--cdn | boolean | false | Load report assets via CDN (unpkg.com)
--assetsDir | string | [cwd]/mochawesome-report/assets | Path to save report assets (js/css)
--charts | boolean | false | Display Suite charts
--code | boolean | true | Display test code
--autoOpen | boolean | false | Automatically open the report
--overwrite | boolean | true | Overwrite existing report files. *See [notes](#overwrite).*
--timestamp, --ts | string | | Append timestamp in specified format to report filename. *See [notes](#timestamp).*
--showPassed | boolean |  true | Set initial state of "Show Passed" filter
--showFailed | boolean |  true | Set initial state of "Show Failed" filter
--showPending | boolean | true | Set initial state of "Show Pending" filter
--showSkipped | boolean | false | Set initial state of "Show Skipped" filter
--showHooks | string | failed | Set the default display mode for hooks <br>• `failed`: show only failed hooks<br>• `always`: show all hooks<br>• `never`: hide all hooks<br>• `context`: show only hooks that have context
--saveJson | boolean | false |Should report data be saved to JSON file
--saveHtml | boolean | true | Should report be saved to HTML file
--dev | boolean | false | Enable dev mode (requires local webpack dev server)
-h, --help | | | Show CLI help


*Boolean options can be negated by adding `--no` before the option. For example: `--no-code` would set `code` to `false`.*

#### 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.

#### overwrite
By default, report files are overwritten by subsequent report generation. Passing `--overwrite=false` will not replace existing files. Instead, if a duplicate filename is found, the report will be saved with a counter digit added to the filename. (ie. `mochawesome_001.html`).

**Note:** `overwrite` will always be `false` when passing multiple files or using the `timestamp` option.

#### timestamp
The `timestamp` option can be used to append a timestamp to the report filename. It uses [dateformat][] to parse format strings so you can pass any valid string that [dateformat][] accepts with a few exceptions. In order to produce valid filenames, the following 
replacements are made:

Characters | Replacement | Example | Output
:--- | :--- | :--- | :---
spaces, commas | underscore | Wed March 29, 2017 | Wed_March_29_2017
slashes | hyphen | 3/29/2017 | 3-29-2017
colons | null | 17:46:21 | 174621

If you pass `true` as the format string, it will default to `isoDateTime`.

### mochawesome `reporter-options`

The above CLI flags can be used as `reporter-options` when using the mochawesome reporter.

Use them in a `.mocharc.js` file:
```js
module.exports = {
    reporter: 'node_modules/mochawesome',
    'reporter-option': [
        'overwrite=true',
        'reportTitle=My\ Custom\ Title',
        'showPassed=false'
    ],
};
```

or as an object when using mocha programmatically:

```js
const mocha = new Mocha({
  reporter: 'mochawesome',
  reporterOptions: {
    overwrite: true,
    reportTitle: 'My Custom Title',
    showPassed: false
  }
});
```

## Development

To develop locally, clone the repo and install dependencies. In order to test end-to-end you must also clone [mochawesome][2] into a directory at the same level as this repo.

You can start the dev server with `npm run devserver`. If you are working on the CLI, use `npm run dev:cli` to watch for changes and rebuild.

### Running Tests

#### Unit Tests
To run unit tests, simply use `npm run test`. You can also run a single unit test with `npm run test:single path/to/test.js`.

#### Functional Tests
Functional tests allow you to run real-world test cases in order to debug the output report. First, start up the dev server in one terminal window with `npm run devserver`. Then, in another window, run the tests with `npm run test:functional`. This will generate a report that you can open in the browser and debug.

If you want to run a specific folder of functional tests:
`npm run test:functional path/to/tests`

Or if you want to run a single test:
`npm run test:functional path/to/test.js`

Or mix and match:
`npm run test:functional path/to/some/tests path/to/another/test.js`
