Allure Jest reference

These are the functions that you can use to integrate your Jest tests with Allure.

In most cases, Allure Jest provides two different ways to use a feature: the Runtime API and the Metadata API.

• Runtime API: use Allure's functions to add certain data to the test result during its execution. This approach allows for constructing the data dynamically.

  Note that it is recommended to call the Allure's functions as close to the beginning of the test as possible. This way, the data will be added even if the test fails early.

• Metadata API: add a metadata tag (beginning with @) into the test name. Allure Jest will extract it and update the test result's data accordingly. When using this approach, the data is guaranteed to be added regardless of how the test itself runs.

Metadata

Assign a test's description, links and other metadata.

Title

• allure.displayName(name: string): PromiseLike<void>

Set the test's title.

import * as allure from "allure-js-commons";

it("Test Authentication", async () => {
  await allure.displayName("Test Authentication");
  // ...
});

Description

• allure.description(markdown: string): PromiseLike<void>

Set the test's description. Markdown formatting is allowed. Any HTML formatting, if present, will be stripped for security purposes.

import * as allure from "allure-js-commons";

it("Test Authentication", async () => {
  await allure.description("This test attempts to log into the website.");
  // ...
});

Owner

• allure.owner(name: string): PromiseLike<void>
• @allure.label.owner:⟨VALUE⟩

Set the test's owner.

Runtime API

import * as allure from "allure-js-commons";

it("Test Authentication", async () => {
  await allure.owner("John Doe");
  // ...
});

Metadata API

it("Test Authentication @allure.label.owner:JohnDoe", async () => {
  // ...
});

Tag

• allure.tag(name: string): PromiseLike<void>
• allure.tags(...tagsList: string[]): PromiseLike<void>
• @allure.label.tag:⟨VALUE⟩

Set the test's tags.

Runtime API

import * as allure from "allure-js-commons";

it("Test Authentication", async () => {
  await allure.tag("New UI");
  await allure.tags("Essentials", "Authentication");
  // ...
});

Metadata API

it(
  "Test Authentication" +
    " @allure.label.tag:NewUI" +
    " @allure.label.tag:Essentials" +
    " @allure.label.tag:Authentication",
  async () => {
    // ...
  },
);

Severity

• allure.severity(name: string): PromiseLike<void>
• @allure.label.severity:⟨VALUE⟩

Set the test's severity.

Allowed values are: “trivial”, “minor”, “normal”, “critical”, and “blocker”.

Runtime API

import * as allure from "allure-js-commons";
import { Severity } from "allure-js-commons";

it("Test Authentication", async () => {
  await allure.severity(Severity.CRITICAL);
  // ...
});

Metadata API

it("Test Authentication @allure.label.severity:critical", async () => {
  // ...
});

Label

• allure.label(name: LabelName | string, value: string): PromiseLike<void>
• allure.labels(...labelsList: Label[]): PromiseLike<void>
• @allure.label.⟨NAME⟩:⟨VALUE⟩

Set an arbitrary label for the test. This is the underlying implementation for a lot of Allure's other functions.

You can call label() multiple times to create an array of values under the given name.

Runtime API

import * as allure from "allure-js-commons";

it("Test Authentication", async () => {
  await allure.label("microservice", "UI");
  // ...
});

Metadata API

it("Test Authentication @allure.label.microservice:UI", async () => {
  // ...
});

ID

• @allure.id:⟨VALUE⟩

Set the test's ID.

import * as allure from "allure-js-commons";

it("Test Authentication @allure.id:123", async () => {
  // ...
});

Link

• allure.link(url: string, name?: string, type?: LinkType | string): PromiseLike<void>
• allure.links(...linksList: Link[]): PromiseLike<void>
• allure.issue(url: string, name?: string): PromiseLike<void>
• allure.tms(url: string, name?: string): PromiseLike<void>

Add a link related to the test.

Based on the type (which can be any string, defaults to “link”), Allure will try to load a corresponding link template to process the URL, as defined by the links configuration option. If no template is found for the given type or if the link already represents a proper URL, it's left unmodified.

The name will be used as the link's text. If it is omitted, the URL will be used instead.

For convenience, Allure provides two shorthand functions with pre-selected link types: issue and tms.

import * as allure from "allure-js-commons";

it("Test Authentication", async () => {
  await allure.issue("AUTH-123", "Related issue");
  await allure.tms("TMS-456", "Related TMS issue");
  await allure.link("JIRA-777", "Related Jira issue", "jira");
  await allure.link("https://example.com/", "Project website");
  // ...
});

Behavior-based hierarchy

• allure.epic(name: string): PromiseLike<void>
• allure.feature(name: string): PromiseLike<void>
• allure.story(name: string): PromiseLike<void>
• @allure.label.epic:⟨VALUE⟩
• @allure.label.feature:⟨VALUE⟩
• @allure.label.story:⟨VALUE⟩

Assign names of epics, features, or user stories for a test, as part of Allure's behavior-based hierarchy.

Runtime API

import * as allure from "allure-js-commons";

it("Test Authentication", async () => {
  await allure.epic("Web interface");
  await allure.feature("Essential features");
  await allure.story("Authentication");
  // ...
});

Metadata API

it(
  "Test Authentication" +
    " @allure.label.epic:WebInterface" +
    " @allure.label.feature:EssentialFeatures" +
    " @allure.label.story:Authentication",
  async () => {
    // ...
  },
);

Suite-based hierarchy

• allure.parentSuite(name: string): PromiseLike<void>
• allure.suite(name: string): PromiseLike<void>
• allure.subSuite(name: string): PromiseLike<void>
• @allure.label.parentSuite:⟨VALUE⟩
• @allure.label.suite:⟨VALUE⟩
• @allure.label.subSuite:⟨VALUE⟩

Assign the names of parent suite, suite, or sub-suite for a test, as part of Allure's suite-based hierarchy.

Runtime API

import * as allure from "allure-js-commons";

it("Test Authentication", async () => {
  await allure.parentSuite("Tests for web interface");
  await allure.suite("Tests for essential features");
  await allure.subSuite("Tests for authentication");
  // ...
});

Metadata API

it(
  "Test Authentication" +
    " @allure.label.parentSuite:TestsForWebInterface" +
    " @allure.label.suite:TestsForEssentialFeatures" +
    " @allure.label.subSuite:TestsForAuthentication",
  async () => {
    // ...
  },
);

Test steps

• allure.step<T = void>(name: string, body: (context: StepContext) => T | PromiseLike<T>): PromiseLike<T>
• allure.logStep(name: string, status?: Status, error?: Error): PromiseLike<void>

Define a test step with the given name.

There are two ways of defining a step.

• Lambda steps

  Write a test step in a function and pass it to allure.step(). If the function returns a value, allure.step() will return it without modification, and it will not affect the report. If it returns a promise, it will be awaited and resolved.

  The function can accept either no arguments or a single object of type StepContext. This object provides the following methods:

  • displayName() — override the step name during its execution.
  • parameter() — indicate arbitrary parameters used for the step. The available signatures of this method are similar to the test-wide implementation, see Parametrized tests.

• No-op steps

  If you call allure.logStep(), Allure will add to the report a no-op step. This allows for a log-style reporting within a test or within a larger step. A no-op step finishes immediately after it started and cannot have any sub-steps, or parameters.

  The optional second argument indicates the status that will be shown for the step in the report. Allowed values are: Status.PASSED (the default), Status.FAILED, Status.BROKEN, and Status.SKIPPED.

  The optional third argument is an Error object. When provided, the data from this object will be displayed in a message inside the step.

import * as allure from "allure-js-commons";
import { Status } from "allure-js-commons";

it("Test Authentication", async () => {
  await allure.step("Step 1", async () => {
    await allure.step("Sub-step 1", async (ctx) => {
      await ctx.parameter("foo", "1");
      // ...
    });
    await allure.step("Sub-step 2", async (ctx) => {
      await ctx.parameter("foo", "2");
      // ...
    });
  });
  await allure.logStep("Step 2", Status.SKIPPED);
});

Parametrized tests

• allure.parameter(name: string, value: string, options?: ParameterOptions): PromiseLike<void>

Specify a name and value of a parameter that was used during this test. See Parametrized tests for more details.

The options argument, if given, must be an object with two optional properties excluded and mode.

• If excluded is set to true, Allure will not use the parameter when comparing the current test result with previous one in the history. See Common pitfall: a test's retries are displayed as separate tests.

• The mode affects how the parameter will be displayed in the report. Available options are:

  • "default" (same as not specifying any mode) — the parameter and its value will be shown in a table along with other parameters.
  • "masked" — the parameter will be shown in the table, but its value will be hidden. Use this mode for passwords, tokens and other sensitive parameters.
  • "hidden" — the parameter and its value will not be shown in the test report.

  Note, that even when you use the "masked" or "hidden" mode, it is still possible to extract the value from the allure_results directory if you publish it.

import * as allure from "allure-js-commons";

test.each([["johndoe"], ["[email protected]"]])("Test Authentication as %s", async (login) => {
  await allure.parameter("login", login);
  await allure.parameter("time", new Date().toUTCString(), { excluded: true });
  // ...
});

Attachments

• allure.attachment(name: string, content: Buffer | string, options: ContentType | string | AttachmentOptions): PromiseLike<void>
• allure.attachmentPath(name: string, path: string, options: ContentType | string | Omit<AttachmentOptions, "encoding">): PromiseLike<void>

Add an attachment to the test result under the given name. Pass either the content or the path from which the data will be read.

The options argument controls the media type of the content and the filename extension that will be used if a user downloads the attachment from the test report. You can either specify both options in an object (as shown for the image attachment below) or just specify the media type and let Allure deduce the appropriate filename extension automatically (as shown for the text attachment below). In either case, the media type can be a value from the ContentType enumeration or any string.

import * as allure from "allure-js-commons";
import { ContentType } from "allure-js-commons";

it("Test Authentication", async () => {
  // ...

  await allure.attachment("Text file", "This is the file content.", ContentType.TEXT);

  await allure.attachmentPath("Screenshot", "/path/to/image.png", {
    contentType: ContentType.PNG,
    fileExtension: "png",
  });
});
