Extra-cucumber-html-reporter NPM

Extra Cucumber HTML Reporter

Extra Cucumber HTML Reporter is a reporting module for Cucumber to parse the JSON output to a beautiful report. The difference between all the other reporting modules on the market is that this module has:

a quick overview of all tested features and scenarios
a features overview that can hold multiple runs of the same feature / runs of the same feature on different browsers / devices
a features overview that can be searched / filtered / sorted
a feature(s) overview with metadata of the used browser(s) / devices

Install

Install this module locally with the following command:

npm install extra-cucumber-html-reporter

Save to dependencies or dev-dependencies:

npm install extra-cucumber-html-reporter --save
npm install extra-cucumber-html-reporter --save-dev

Usage

const report = require('extra-cucumber-html-reporter');

report.generate({
	jsonDir: './path-to-your-json-output/',
	reportPath: './path-where-the-report-needs-to-be/',
	metadata:{
        browser: {
            name: 'chrome',
            version: '60'
        },
        device: 'Local test machine',
        platform: {
            name: 'ubuntu',
            version: '16.04'
        }
    },
    customData: {
        title: 'Run info',
        data: [
            {label: 'Project', value: 'Custom project'},
            {label: 'Release', value: '1.2.3'},
            {label: 'Cycle', value: 'B11221.34321'},
            {label: 'Execution Start Time', value: 'Nov 19th 2017, 02:31 PM EST'},
            {label: 'Execution End Time', value: 'Nov 19th 2017, 02:56 PM EST'}
        ]
    }
});

Make sure that, when you generate the JSON files with Cucumber, each file will have a UNIQUE name. If you don't provide a unique name Cucumber will override the JSON files.
Advice is to use for example the name of the feature, the name of the browser / device it is running on AND a unix timestamp with for example this (new Date).getTime();. This will result in something like this name_of_feature.chrome.1495298685509.json

Options

`jsonDir`

Type: String
Mandatory: Yes

The directory that will hold all the generated JSON files, relative from where the script is started.

N.B.: If you use a npm script from the command line, like for example npm run generate-report the jsonDir will be relative from the path where the script is executed. Executing it from the root of your project will also search for the jsonDir from the root of you project.

`reportPath`

Type: String
Mandatory: Yes

The directory in which the report needs to be saved, relative from where the script is started.

N.B.: If you use a npm script from the command line, like for example npm run generate-report the reportPath will be relative from the path where the script is executed. Executing it from the root of your project will also save the report in the reportPath in the root of you project.

`staticFilePath`

Type: boolean
Mandatory: No

If true each feature will get a static filename for the html. Use this feature only if you are not running multiple instances of the same tests.

`openReportInBrowser`

Type: boolean
Mandatory: No

If true the report will automatically be opened in the default browser of the operating system.

`saveCollectedJSON`

Type: boolean
Mandatory: No

This module will first merge all the JSON-files to 1 file and then enrich it with data that is used for the report. If saveCollectedJSON :true the merged JSON AND the enriched JSON will be saved in the reportPath. They will be saved as:

merged-output.json
enriched-output.json

`disableLog`

Type: boolean
Mandatory: No
Default: false

This will disable the log so will NOT see this.

=====================================================================================
    Multiple Cucumber HTML report generated in:

    /Users/wswebcreation/multiple-cucumber-html-reporter/.tmp/index.html
========================================================================

`pageTitle`

Type: string
Mandatory: No
Default: Multiple Cucumber HTML Reporter

You can change the report title in the HTML head Tag

`reportName`

Type: string
Mandatory: No

You can change the report name to a name you want

`pageFooter`

Type: string
Mandatory: No

You can customise Page Footer if required. You just need to provide a html string like <div><p>A custom footer in html</p></div>

`displayDuration`

Type: boolean
Mandatory: No

If set to true the duration of steps, scenarios and features is displayed on the Features overview and single feature page in an easily readable format. This expects the durations in the report to be in nanoseconds, which might result in incorrect durations when using a version of Cucumber(JS 2 and 3) that does not report in nanoseconds but in milliseconds. This can be changed to milliseconds by adding the parameter durationInMS: true, see below

NOTE: Only the duration of a feature can be shown in the features overview. A total duration over all features CAN NOT be given because the module doesn't know if all features have been run in parallel

`durationInMS`

Type: boolean
Default: false
Mandatory: No

If set to true the duration of steps will be expected to be in milliseconds, which might result in incorrect durations when using a version of Cucumber(JS 1 or 4) that does report in nanaseconds. This parameter relies on displayDuration: true

`useCDN`

Type: boolean
Mandatory: No

If you prefer, you can use CDN for assets.

`customStyle`

Type: path
Mandatory: No

If you need add some custom style to your report. Add it like this customStyle: 'your-path-where/custom.css'

`overrideStyle`

Type: path
Mandatory: No

If you need replace default style for your report. Add it like this overrideStyle: 'your-path-where/custom.css'

`metadata`

Type: JSON
Mandatory: No

Print more data to your report, such as browser name + version, platform name + version and your environment. The values need to meet some predefined data, see Metadata for more info. Data can be passed like below.

If you provide the metadata when instantiating multi-cucumber-html-reporter the metadata will be added to each feature. If you already have metadata in your JSON then the metadata in the JSON will take precedence

metadata:{
    browser: {
        name: 'chrome',
        version: '60'
    },
    device: 'Local test machine',
    platform: {
        name: 'ubuntu',
        version: '16.04'
    }
}

See metadata for more info

`customMetadata`

Type: boolean
Mandatory: No

It is possible to provide custom metadata by setting this variable to true. Custom metadata will override the regular metadata completely and potentially have strange formatting bugs if too many (10+) variables are used. The columns will be in the order defined by the order of the list.

Adding the metadata is done in the same way as with normal metadata. The metadata is formed as a list of key-value pairs to preserve order:

metadata: [
        {name: 'Environment v.', value: '12.3'},
        {name: 'Plugin v.', value: '32.1'},
        {name: 'Variable set', value: 'Foo'}
    ]

On the features overview page the custom metadata is shown like: Snapshot - Features overview custom metadata

IMPORTANT: This does not work correctly if features have different sets of metadata. Try to avoid this situation.

`customData`

Type: object
Mandatory: No

You can add a custom data block to the report like this

Snapshot - Features overview custom data

customData: {
    title: 'Run info',
    data: [
        {label: 'Project', value: 'Custom project'},
        {label: 'Release', value: '1.2.3'},
        {label: 'Cycle', value: 'B11221.34321'},
        {label: 'Execution Start Time', value: 'Nov 19th 2017, 02:31 PM EST'},
        {label: 'Execution End Time', value: 'Nov 19th 2017, 02:56 PM EST'}
    ]
}

`customData.title`

Type: string
Mandatory: No
Default: Custom data title

Select a title for the custom data block. If not provided it will be defaulted.

`customData.data`

Type: array
Mandatory: yes

The data you want to add. This needs to be in the format

data: [
    {label: 'your label', value: 'the represented value'}
]

Metadata

The report can also show on which browser / device a feature has been executed. It is shown on the featurs overview in the table as well as on the feature overview in a container.

Adding metadata to the Cucumber JSON

To be able to see this you will need to add the following to the Cucumber JSON before you save it.

// This represents the Cucumber JSON file that has be retrieved
const cucumberJSON;

const metadata = {
	"browser": {
		"name": "chrome",
		"version": "58"
	},
	"device": "string",
	"platform": {
		"name": "osx",
		"version": "10.12"
	}
}

// Add it with for example
cucumberJSON[0].metadata = metadata;

// Now save the file to the disk

`metadata.app.name`

Type: string

e.g.: The name of the app.

`metadata.app.version`

Type: string

e.g.: The version of the app.

`metadata.browser.name`

Type: string
Possible values: internet explorer | edge | chrome | firefox | safari

If no correct value is provided the ?-icon with the text not known is shown

`metadata.browser.version`

Type: string

e.g.: The version of the browser, this can be added manual or retrieved during the execution of the tests to get the exact version number.

If no correct value is provided the ?-icon with the text not known is shown

`metadata.device`

Type: string

e.g.: A name that represents the type of device. For example, if you run it on a virtual machine, you can place it here Virtual Machine, or the name of the mobile, like for example iPhone 7 Plus.

If no correct value is provided the ?-icon with the text not known is shown

`metadata.platform.name`

Type: string
Possible values: windows | osx | linux | ubuntu | android | ios

If no correct value is provided the ?-icon with the text not known is shown

`metadata.platform.version`

Type: string

e.g.: The version of the platform

If no correct value is provided the ?-icon with the text not known is shown

FAQ

Only 1 report is shown in the features overview table

It could be that the name of the Cucumber JSON file that has been saved is not unique (enough).

My advice is to use for example:

the name of the feature
the name of the browser / device it is running on
a unix timestamp with for example this (new Date).getTime();

This will result in something like this name_of_feature.chrome.1495298685509.json.

The advantage of this is that when you look at the folder where the Cucumber JSON-files are saved you can see:

the features that have been executed
on which browser
a timestamp to see which feature has been executed the last (if featurename and browser are the same)

Metdata shows `not known` or not the correct icons

There could be 2 causes:

The metadata has not (correctly) been added to the Cucumber JSON.
The metadata.browser.name or metadata.platform.name can't be mapped to the right icon

To fix this see the part about Metadata and check the possible values.

How to attach Screenshots to HTML report

You can attach screenshots at any time to a Cucumber JSON file. Just create a Cucumber scenario-hook that will handle this. You can add them during running or when a scenario failed. Snapshot - Scenario browser / device info not known](./docs/images/scenario-no-metadata.jpg "Snapshot - Scenario browser / device info not known")

Check the framework you are using to attach screenshots to the JSON file.

How to attach Plain Text to HTML report

You can attach plain-text / data at any time to a Cucumber JSON file to help debug / review the results. You can add them during running or when a scenario failed.
