Jest-Allure2

An up to date Jest reporter that produces Allure 2 reports.

Originally forked from jest-allure, this project uses the latest allure configuration ^2.0.0-beta.6.

Allure Framework is a flexible lightweight multi-language test report tool that not only shows a very concise representation of what have been tested in a neat web report form, but allows everyone participating in the development process to extract maximum of useful information from everyday execution of tests.

Features:

• Most robust Allure API currently available to Jest.

• Support for new attachment types that were not supported on previous versions.

• Allure result files are now JSON, replacing the legacy XML format.

Requirements

Resource	Description
Jest	A delightful JavaScript testing framework.
Allure 2 CLI	"A Java jar command line tool that turns Allure result files into beautiful Allure reports."

:rocket: Quick start

1. Add this package

yarn add --dev jest-allure2

1. Update jest.setup.js

var {registerAllure} = require('jest-allure2')

registerAllure()

1. Run tests

yarn test

1. Generate the Allure report

allure generate

Advanced features

Add descriptions, screenshots, steps, severity and lots of other fancy details to the report.

The global variable will have a new allure object available with the following methods:

    allure.description(description: string): this;
    allure.severity(severity: Severity): this;
    allure.epic(epic: string): this;
    allure.feature(feature: string): this;
    allure.story(story: string): this;
    allure.step(name: string, status: string | (args:[any]) => string): this;
    allure.environment(name: string, value: string): this;
    allure.attachment(name: string, buffer: any, type: string): this;
    allure.label(name: string, value: string): this;
    allure.tag(name: string): this;
    allure.parameter(name: string, value: string): this;
    allure.issue(id: string): this;
    allure.tms(id: string): this;

Example

// Test subject
function sum(a: number, b: number): number {
  return a + b
}

// Tests
describe("Number functions", () => {
    beforeEach('Setup', ()=>{
        allure.severity(Severity.Critical)
        allure.feature(Feature.Billing)
        allure.story("BILL-217")
    })

    test("sum performs addition functionality", () => {
        allure.description("Tests should be ran when billing functionality is changed.")

        allure.step("Two integers can be added together.", () => {
            allure.parameter('a', 3)
            allure.parameter('b', 4)
            expect(sum(3,4)).toBe(7)
        })

        allure.step("Two floats can be added together", () => {
            allure.parameter('a', 3.141)
            allure.parameter('b', 2.571)
            expect(sum(3.141, 2.571)).toBe(5.712)
        })

        allure.step("Two objects can be added together", () => {
            const a = {"a": 1}
            const b = {"b": 2}

            allure.parameter('a', a)
            allure.parameter('b', b)
            expect(sum(a, b)).toMatchSnapshot()
        })
    });
});

:gear: Options

The main export registerAllure() accepts three optional configuration arguments:

Parameter	Description	Default
resultsDir	File path where result files are written.	"allure-results"
environmentInfo	Key value pairs that will appear under the environment section of the Allure report	{}
testMapper	Decorator that receives Allure test result objects.	undefined

// jest.setup.js
var resultsDir = 'allure-results'
var environmentInfo = {"Username": "User-1331", "password": "password-1331"}
var testMapper = results => {
    if (result.status == Status.SKIPPED) {
        result.fullName = `(WAS SKIPPED) ${result.fullName}`
    }
    return result
}

registerAllure(resultsDir, environmentInfo, testMapper)
