Cucumber

Cucumber is a tool for running automated tests written in plain language. Because they're written in plain language, they can be read by anyone on your team. Because they can be read by anyone, you can use them to help improve communication, collaboration and trust on your team.

Cucumber.js is the JavaScript implementation of Cucumber and runs on the maintained Node.js versions and modern web browsers.

pretty formatter has been removed. All errors are now reported in a pretty format instead. The progress formatter is now the default.
Major changes to custom formatter and custom snippet syntax APIs due to rewrite in support of the event protocol. Please see the updated documentation.
Remove registerHandler and registerListener. Use BeforeAll / AfterAll for setup code. Use the event protocol formatter if used for reporting. Please open an issue if you have another use case.
Remove deprecated addTransform. Use defineParameterType instead.
cucumber-expressions:
- using an undefined parameter type now results in an error
- {stringInDoubleQuotes} is now {string} which works for strings in single or double quotes
Undefined steps fail the build in non-strict mode. Non-strict mode only allows pending steps now.

Add BeforeAll / AfterAll hooks for suite level setup / teardown
Add event protocol formatter

// Using defineSupportCode
var {defineSupportCode} = require('cucumber');

defineSupportCode(function({Given}) {
  Given(/^a step$/, function() {});
});

// Using aliases
var {Given} = require('cucumber');

Given(/^a step$/, function() {});

(Nico Jansen and Łukasz Gandecki)

2.2.0 (2017-05-20)

New Features

Add progress-bar formatter inspired by fuubar-cucumber and fuubar which outputs a progress bar and errors as they happen

Bug Fixes

throw descriptive error message when running a global install

1.3.3 (2016-04-26)

Documentation

fix CLI format-options name (#703, Florian Ribon)
add link on README.md to custom formatters documentation

2.0.0-rc.4 (2016-12-19)

Breaking Changes

update support code library interface - instead of exporting a function and calling methods on this, require the cucumber module and call defineSupportCode which passes an object as the first argument whch exposes the methods. Overriding the world constructor has changed from overriding the World property to calling setWorldConstructor.

  // 1.3.1
  module.exports = function () {
    this.Given(/^a step$/, function() {});
    this.World = CustomWorld
  });

  // 2.0.0
  var {defineSupportCode} = require('cucumber');

  defineSupportCode(function({Given, setWorldConstructor}) {
    Given(/^a step$/, function() {});
    setWorldConstructor(CustomWorld);
  });

2.0.0-rc.3 (2016-12-19)

Breaking Changes

make strict the default
- previously pending and undefined steps did not cause an exit code of 1. This could be overridden with --strict. Strict is now the default and you can use --no-strict to return to the previous behavior.
update automatically required files
- if the features live in a features directory at any level, all support files in the features directory are loaded.

Bug Fixes

prevent crash on empty feature file

New Features

validate argument types

Documentation

docs: fix tag expression migration guide (#691, Aslak Hellesøy)

2.0.0-rc.2 (2016-12-04)

Breaking Changes

pass attach to world constructor instead of assigning it to world
- the world constructor now receives {attach, parameters} as the first argument instead of parameters

New Features

json formatter: add isBackground to steps

Bug Fixes

clear timeouts of asynchronous hooks/steps
stop running features with no scenarios

Documentation

update node js example

2.0.0-rc.1 (2016-11-25)

Bug Fixes

fix browser version

2.0.0-rc.0 (2016-11-25)

Breaking Changes

Dropped support for Node 0.10
CLI
- --colors / --no-colors has moved to --format-options '{"colorsEnabled": <BOOLEAN>}'
- --require <DIR|FILE>: the required files are no longer reordered to require anything in a support directory first
- --snippet-interface <INTERFACE> has moved to --format-options '{"snippetInterface": "<INTERFACE>"}'
- --snippet-syntax <SYNTAX> has moved to --format-options '{"snippetSyntax": "<SYNTAX>"}'
- --tags <EXPRESSION> now uses cucumber-tag-expressions. It is no longer repeatable and new values will override previous
  - --tags @dev stays the same
  - --tags ~@dev becomes --tags 'not @dev'
  - --tags @foo,@bar becomes --tags '@foo or @bar'
  - --tags @foo --tags @bar becomes --tags '@foo and @bar'
Internals
- complete rewrite using ES2015 and promises
JSON Formatter
- String attachments are no longer base64 encoded. Buffer and Stream attachments are still base64 encoded.
Support Files
- Attachments
  - The attach function used for adding attachments moved from the API scenario object to world. It is thus now available in step definitions without saving a reference to the scenario.
```
  // 1.3.0
  this.After(function(scenario, callback) {
    scenario.attach(new Buffer([137, 80, 78, 71]), 'image/png')
  });

  // 2.0.0
  this.After(function() {
    this.attach(new Buffer([137, 80, 78, 71]), 'image/png');
  });
```
  - When attaching buffers or strings, the callback argument is ignored.
- Hooks
  - Hooks now receive a ScenarioResult instead of the Scenario
```
  // 1.3.0
  this.After(function(scenario) {});

  // 2.0.0
  this.After(function(scenarioResult) {});
```
  - The tags option for hook should now be a string instead of an array and uses cucumber-tag-expressions
```
  // 1.3.0
  this.Before({tags: ["@foo"]}, function (scenario) {})
  this.Before({tags: ["@foo,@bar"]}, function (scenario) {})
  this.Before({tags: ["@foo", "@bar"]}, function (scenario) {})

  // 2.0.0
  this.Before({tags: "@foo"}, function (scenario) {})
  this.Before({tags: "@foo and @bar"}, function (scenario) {})
  this.Before({tags: "@foo or @bar"}, function (scenario) {})
```
- Step Definitions
  - String patterns were removed in favor cucumber-expressions
  - Regular Expressions
    - capture groups matching (-?\d+) will be automatically converted to an integer using parseInt
    - capture groups matching (-?\d*\.?\d+) will be automatically converted to a float using parseFloat
  - Generator functions are no longer automatically run with co. To retain the previous functionality, use this.setDefinitionFunctionWrapper
- Event Handlers
  - Objects no longer have get* methods and instead have exposed properties
    - For example: scenario.getName() is now just scenario.name
  - StepResult duration is now in milliseconds instead of nanoseconds

Bug Fixes

remove empty lines from @rerun files (#660, Cody Ray Hoeft)
catch uncaught errors in the browser (Charlie Rudolph)

New Features

Support Files
- Attachments:
  - When attaching a stream, the interface can either accept a callback as a third argument or will return a promise if not passed a callback
