mochawesome-report-generator (marge)

marge (mochawesome-report-generator) is the counterpart to mochawesome, a custom reporter for use with the Javascript testing framework, mocha. Marge takes the JSON output from mochawesome and generates a full fledged HTML/CSS report that helps visualize your test suites.

CLI for generating reports independent of mochawesome

Usage with mochawesome

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'
});

CLI Usage

Install mochawesome-report-generator package

npm install -g mochawesome-report-generator

Run the command

marge [options] data_file [data_file2 ...]

Options

CLI Flags

marge can be configured via the following command line flags:

Flag	Type	Default	Description
-f, --reportFilename	string		Filename of saved report
-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	true	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.
--timestamp, --ts	string		Append timestamp in specified format to report filename. See notes.
--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
--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.

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

Further, if you pass the flag with no 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 mocha.opts file:

--reporter mochawesome
--reporter-options overwrite=true,reportTitle=My\ Custom\ Title,showPassed=false

or as an object when using mocha programmatically:

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 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
