newman _{the cli companion for postman}

Newman is a command-line collection runner for Postman. It allows you to effortlessly run and test a Postman collection directly from the command-line. It is built with extensibility in mind so that you can easily integrate it with your continuous integration servers and build systems.

Getting started

To run Newman, ensure that you have Node.js >= v6. Install Node.js via package manager.

Installation

The easiest way to install Newman is using NPM. If you have Node.js installed, it is most likely that you have NPM installed as well.

$ npm install -g newman

This installs Newman globally on your system allowing you to run it from anywhere. If you want to install it locally, Just remove the -g flag.

Usage

Using Newman CLI

The newman run command allows you to specify a collection to be run. You can easily export your Postman Collection as a json file from the Postman App and run it using Newman.

$ newman run examples/sample-collection.json

If your collection file is available as an URL (such as from our Cloud API service), Newman can fetch your file and run it as well.

$ newman run https://www.getpostman.com/collections/631643-f695cab7-6878-eb55-7943-ad88e1ccfd65-JsLv

For the complete list of options, refer the Command Line Options section below.

Using Newman as a Library

Newman can be easily used within your JavaScript projects as a Node.js module. The entire set of Newman CLI functionality is available for programmatic use as well. The following example runs a collection by reading a JSON collection file stored on disk.

const newman = require('newman'); // require newman in your project

// call newman.run to pass `options` object and wait for callback
newman.run({
    collection: require('./sample-collection.json'),
    reporters: 'cli'
}, function (err) {
	if (err) { throw err; }
    console.log('collection run complete!');
});

For the complete list of options, refer the API Reference section below.

Using Reporters with Newman

Reporters provide information about the current collection run in a format that is easy to both: disseminate and assimilate. Reporters can be configured using the -r or --reporters options. Inbuilt reporters in newman are: cli, json, junit, progress and emojitrain.

CLI reporter is enabled by default when Newman is used as a CLI, you do not need to specifically provide the same as part of reporters option. However, enabling one or more of the other reporters will result in no CLI output. Explicitly enable the CLI option in such a scenario. Check the example given below using the CLI and JSON reporters:

$ newman run examples/sample-collection.json -r cli,json

For more details on Reporters and writing your own External Reporters refer to their corresponding sections below.

Command Line Options

`newman [options]`

-h, --help
Show command line help, including a list of options, and sample use cases.
-v, --version
Displays the current Newman version, taken from package.json

`newman run <collection-file-source> [options]`

-e <source>, --environment <source>
Specify an environment file path or URL. Environments provide a set of variables that one can use within collections. Read More
-g <source>, --globals <source>
Specify the file path or URL for global variables. Global variables are similar to environment variables but have a lower precedence and can be overridden by environment variables having the same name.
-d <source>, --iteration-data <source>
Specify a data source file (CSV) to be used for iteration as a path to a file or as a URL. Read More
-n <number>, --iteration-count <number>
Specifies the number of times the collection has to be run when used in conjunction with iteration data file.
--folder <name>
Run requests within a particular folder/folders in a collection. Multiple folders can be specified by using --folder multiple times, like so: --folder f1 --folder f2.
--export-environment <path>
The path to the file where Newman will output the final environment variables file before completing a run.
--export-globals <path>
The path to the file where Newman will output the final global variables file before completing a run.
--export-collection <path>
The path to the file where Newman will output the final collection file before completing a run.
--timeout <ms>
Specify the time (in milliseconds) to wait for the entire collection run to complete execution.
--timeout-request <ms>
Specify the time (in milliseconds) to wait for requests to return a response.
--timeout-script <ms>
Specify the time (in milliseconds) to wait for scripts to complete execution.
-k, --insecure
Disables SSL verification checks and allows self-signed SSL certificates.
--ignore-redirects
Prevents newman from automatically following 3XX redirect responses.
--delay-request
Specify the extent of delay between requests (milliseconds).
--bail [optional modifiers]
Specify whether or not to stop a collection run on encountering the first test script error.
Can optionally accept modifiers, currently include folder and failure.
folder allows you to skip the entire collection run in case an invalid folder was specified using the --folder option or an error was encountered in general.
On the failure of a test, failure would gracefully stop a collection run after completing the current test script.
-x, --suppress-exit-code
Specify whether or not to override the default exit code for the current run.
--color <value>
Enable or Disable colored CLI output. The color value can be any of the three: on, off or auto(default).
With auto, Newman attempts to automatically turn color on or off based on the color support in the terminal. This behaviour can be modified by using the on or off value accordingly.
--disable-unicode
Specify whether or not to force the unicode disable option. When supplied, all symbols in the output will be replaced by their plain text equivalents.
--global-var "<global-variable-name>=<global-variable-value>"
Allows the specification of global variables via the command line, in a key=value format. Multiple CLI global variables can be added by using --global-var multiple times, like so: --global-var "foo=bar" --global-var "alpha=beta".

SSL Client Certificates

Client certificates are an alternative to traditional authentication mechanisms. These allow their users to make authenticated requests to a server, using a public certificate, and an optional private key that verifies certificate ownership. In some cases, the private key may also be protected by a secret passphrase, providing an additional layer of authentication security.

Newman supports SSL client certificates, via the following CLI options (available with Newman v3 style run only):

--ssl-client-cert
The path to the public client certificate file.
--ssl-client-key
The path to the private client key (optional).
--ssl-client-passphrase
The secret passphrase used to protect the private client key (optional).

Configuring Proxy

Newman can also be configured to work with proxy settings via the following environment variables:

HTTP_PROXY / http_proxy
HTTPS_PROXY / https_proxy
NO_PROXY / no_proxy

For more details on using these variables, refer here.

API Reference

newman.run(options: object , callback: function) => run: EventEmitter

The run function executes a collection and returns the run result to a callback function provided as parameter. The return of the newman.run function is a run instance, which emits run events that can be listened to.

Parameter	Description
options	This is a required argument and it contains all information pertaining to running a collection. Required Type: `object`
options.collection	The collection is a required property of the `options` argument. It accepts an object representation of a Postman Collection which should resemble the schema mentioned at https://schema.getpostman.com/. The value of this property could also be an instance of Collection Object from the Postman Collection SDK. As `string`, one can provide a URL where the Collection JSON can be found (e.g. Postman Cloud API service) or path to a local JSON file. Required Type: `object\|string` PostmanCollection
options.environment	One can optionally pass an environment file path or URL as `string` to this property and that will be used to read Postman Environment Variables from. This property also accepts environment variables as an `object`. Environment files exported from Postman App can be directly used here. Optional Type: `object\|string`
options.globals	Postman Global Variables can be optionally passed on to a collection run in form of path to a file or URL. It also accepts variables as an `object`. Optional Type: `object\|string`

newman.run~callback(error: object , summary: object)

The callback parameter of the newman.run function receives two arguments: (1) error and (2) summary

Argument	Description
error	In case newman faces an error during the run, the error is passed on to this argument of callback. By default, only fatal errors, such as the ones caused by any fault inside Newman is passed on to this argument. However, setting `abortOnError:true` or `abortOnFailure:true` as part of run options will cause newman to treat collection script syntax errors and test failures as fatal errors and be passed down here while stopping the run abruptly at that point. Type: `object`
summary	The run summary will contain information pertaining to the run. Type: `object`
summary.error	An error object which if exists, contains an error message describing the message Type: `object`
summary.collection	This object contains information about the collection being run, it's requests, and their associated pre-request scripts and tests. Type: `object`
summary.environment	An object with environment variables used for the current run, and the usage status for each of those variables. Type: `object`
summary.globals	This object holds details about the globals used within the collection run namespace. Type: `object`
summary.run	A cumulative run summary object that provides information on . Type: `object`
summary.run.stats	An object which provides details about the total, failed, and pending counts for pre request scripts, tests, assertions, requests, and more. Type: `object`
summary.run.failures	An array of failure objects, with each element holding details, including the assertion that failed, and the request. Type: `array.<object>`
summary.run.executions	This object contains information about each request, along with it's associated activities within the scope of the current collection run. Type: `array.<object>`

newman.run~events

Newman triggers a whole bunch of events during the run.

newman.run({
    collection: require('./sample-collection.json'),
    iterationData: [{ "var": "data", "var_beta": "other_val" }],
    globals: {

Reporters

Configuring Reporters

-r <reporter-name>, --reporters <reporter-name>
Specify one reporter name as string or provide more than one reporter name as a comma separated list of reporter names. Available reporters are: cli, json, junit, progress and emojitrain.

Spaces should not be used between reporter names / commas whilst specifying a comma separated list of reporters. For instance:

✅ -r cli,json,junit
❌ -r cli , json,junit
--reporter-{{reporter-name}}-{{reporter-option}}
When multiple reporters are provided, if one needs to specifically override or provide an option to one reporter, this is achieved by prefixing the option with --reporter-{{reporter-name}}-.

For example, ... --reporters cli,json --reporter-cli-silent would silence the CLI reporter only.
--reporter-{{reporter-options}}
If more than one reporter accepts the same option name, they can be provided using the common reporter option syntax.

For example, ... --reporters cli,json --reporter-silent passes the silent: true option to both JSON and CLI reporter.

Note: Sample collection reports have been provided in examples/reports.

CLI Reporter

The built-in CLI reporter supports the following options, use them with appropriate argument switch prefix. For example, the option no-summary can be passed as --reporter-no-summary or --reporter-cli-no-summary.

CLI reporter is enabled by default when Newman is used as a CLI, you do not need to specifically provide the same as part of --reporters option. However, enabling one or more of the other reporters will result in no CLI output. Explicitly enable the CLI option in such a scenario.

CLI Option	Description
`--reporter-cli-silent`	The CLI reporter is internally disabled and you see no output to terminal.
`--reporter-cli-no-summary`	The statistical summary table is not shown.
`--reporter-cli-no-failures`	This prevents the run failures from being separately printed.
`--reporter-cli-no-assertions`	This turns off the output for request-wise assertions as they happen.
`--reporter-cli-no-success-assertions`	This turns off the output for successful assertions as they happen.
`--reporter-cli-no-console`	This turns off the output of `console.log` (and other console calls) from collection's scripts.
`--reporter-cli-no-banner`	This turns off the `newman` banner shown at the beginning of each collection run.

JSON Reporter

The built-in JSON reporter is useful in producing a comprehensive output of the run summary. It takes the path to the file where to write the report. The content of this file is exactly the same as the summary parameter sent to the callback when Newman is used as a library.

To enable JSON reporter, provide --reporters json as a CLI option.

CLI Option	Description
`--reporter-json-export <path>`	Specify a path where the output JSON file will be written to disk. If not specified, the file will be written to `newman/` in the current working directory. If the specified path does not exist, it will be created. However, if the specified path is a pre-existing directory, the report will be generated in that directory.

JUNIT/XML Reporter

The built-in JUnit reporter can output a summary of the collection run to a JUnit compatible XML file. To enable the JUNIT reporter, provide --reporters junit as a CLI option.

CLI Option	Description
`--reporter-junit-export <path>`	Specify a path where the output XML file will be written to disk. If not specified, the file will be written to `newman/` in the current working directory. If the specified path does not exist, it will be created. However, if the specified path is a pre-existing directory, the report will be generated in that directory.

Older command line options are supported, but are deprecated in favour of the newer v3 options and will soon be discontinued. For documentation on the older command options, refer to README.md for Newman v2.X.

HTML Reporter

Its an external reporter which can be installed via npm install -g newman-reporter-html. The complete installation and usage guide is available at newman-reporter-html. Once HTML reporter is installed you can provide --reporters html as a CLI option.

back to top

External Reporters

Using External Reporters

Newman also supports external reporters, provided that the reporter works with Newman's event sequence. Working examples on how Newman reporters work can be found in lib/reporters. For instance, to use the Newman HTML Reporter:

Install the reporter package. Note that the name of the package is of the form newman-reporter-<name>. The installation should be global if newman is installed globally, local otherwise. (Remove -g flag from the command below for a local installation.)

$ npm install -g newman-reporter-html

Use the installed reporter, either via the CLI, or programmatic usage. Here, the newman-reporter prefix is not required while specifying the reporter name in the options.

$ newman run /path/to/collection.json -r cli,html

const newman = require('newman');

newman.run({
    collection: '/path/to/collection.json',
    reporters: ['cli', 'html']
}, process.exit);

Community Maintained Reporters

Creating Your Own Reporter

A custom reporter is a Node module with a name of the form newman-reporter-<name>. To create a custom reporter:

Navigate to a directory of your choice, and create a blank npm package with npm init.
Add an index.js file, that exports a function of the following form:

function CustomNewmanReporter (emitter, reporterOptions, collectionRunOptions) {
  // emitter is an event emitter that triggers the following events: https://github.com/postmanlabs/newman#newmanrunevents
  // reporterOptions is an object of the reporter specific options. See usage examples below for more details.
  // collectionRunOptions is an object of all the collection run options: https://github.com/postmanlabs/newman#newmanrunoptions-object--callback-function--run-eventemitter
}

Publish your reporter using npm publish, or use your reporter locally see usage instructions.

Scoped reporter package names like @myorg/newman-reporter-<name> are also supported. Working reporter examples can be found in lib/reporters.

File uploads

Newman also supports file uploads for request form data. The files must be present in the current working directory. Your collection must also contain the filename in the "src" attribute of the request.

In this collection, sample-file.txt should be present in the current working directory.

{
    "info": {
        "name": "file-upload"
    },
    "item": [
        {
            "request": {
                "url": "https://postman-echo.com/post",
                "method": "POST",
                "body": {
                    "mode": "formdata",
                    "formdata": [
                        {
                            "key": "file",
                            "type": "file",
                            "enabled": true,
                            "src": "sample-file.txt"
                        }
                    ]
                }
            }
        }
    ]
