Note for users of Mac with Apple silicon

If you're developing on a Mac machine with Apple silicon, make sure you have Rosetta installed. Follow this article for the instructions: https://support.apple.com/en-us/HT211861

You may also install Rosetta via the CLI:

/usr/sbin/softwareupdate --install-rosetta --agree-to-license

Configuration

The Allure lifecycle is configured via a JSON file with the default name allureConfig.json. NuGet package installs allureConfig.Template.json, which you can use as an example. There are two ways to specify config file location:

• Set the ALLURE_CONFIG environment variable to the full path of the file.
• Add allureConfig.json to the project and ensure it's copied to the project output directory next to Allure.Net.Commons.dll:

  <ItemGroup>
    <None Update="allureConfig.json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </None>
  </ItemGroup>

The Allure lifecycle will start with the default configuration settings if no allureConfig.json is provided.

The unparsed configuration can be accessed via AllureLifeCycle.Instance.JsonConfiguration. Adapters can use it to read extended configuration properties they need. Check an example here.

The parsed configuration object can be accessed via AllureLifeCycle.Instance.Configuration.

An example of the configuration file is provided below:

{
  "allure": {
    "directory": "allure-results",
    "title": "custom run title",
    "links":
    [
      "https://example.org/{link}",
      "https://example.org/{issue}",
      "https://example.org/{tms}"
    ],
    "failExceptions": [
      "MyNamespace.MyAssertionException"
    ]
  }
}

The directory property defaults to "allure-results".

All link pattern placeholders will be replaced with the URL value of the corresponding link type. Given the configuration above, the following transformation will be made:

link(type: "issue", url: "BUG-01") => https://example.org/BUG-01

failExceptions must be an array of strings, each representing the full name of an exception type. If an unhandled exception occurs whose type matches one of the provided types, the test/step/fixture is considered failed. Otherwise, it's considered broken. An exception's type matches a name if:

1. Its full name equals the provided name, OR
2. One of its base classes matches the name, OR
3. It implements an interface that matches the name.

The ExtendedApi facade

Use this class to access some less commonly used functions.

Explicit step management

Note

Use the functions below only if lambda steps don't suit your needs.

• StartStep(string): void
• StartStep(string, Action<StepResult>): void
• PassStep(): void
• PassStep(Action<StepResult>): void
• FailStep(): void
• FailStep(Action<StepResult>): void
• BreakStep(): void
• BreakStep(Action<StepResult>): void

Lambda fixtures

• Before(string, Action): void - setup fixture action.
• Before<T>(string, Func<T>): T - setup fixture function.
• Before(string, Func<Task>): Task - async setup fixture action.
• Before<T>(string, Func<Task<T>>): T - async setup fixture function.
• After(string, Action): void - teardown fixture action.
• After<T>(string, Func<T>): T - teardown fixture function.
• After(string, Func<Task>): Task - async teardown fixture action.
• After<T>(string, Func<Task<T>>): T - async teardown fixture function.

Explicit fixture management

Note

Use the functions below only if lambda fixtures don't suit your needs.

• StartBeforeFixture(string): void
• StartAfterFixture(string): void
• PassFixture(): void
• PassFixture(Action<FixtureResult>): void
• FailFixture(): void
• FailFixture(Action<FixtureResult>): void

The integration API

This API is designed for adapter or library authors. You may still use it as a test author, but we recommend considering the Runtime API first.

AllureLifecycle

The AllureLifecycle class provides methods to manipulate the Allure context while responding to the test framework's events. Use AllureLifecycle.Instance property to access it.

Fixture context control

• StartBeforeFixture
• StartAfterFixture
• UpdateFixture
• StopFixture

Test context control

• ScheduleTestCase
• StartTestCase
• UpdateTestCase
• StopTestCase
• WriteTestCase

Step context control

• StartStep
• UpdateStep
• StopStep

Utility Methods

• CleanupResultDirectory - can be used in test run setup to clean old result files

Context capturing

The methods above operate on the current Allure context. This context flows naturally as a part of ExecutionContext and is subject to the same constraints. Notably, changes made in an async callee can't be observed by the caller.

Use the following methods of AllureLifecycle to capture the current Allure context and to operate on the captured context later:

• Context
• RunInContext

Example:

public static async Task Caller(ScenarioContext scenario)
{
    await Callee(scenario);
    AllureLifecycle.Instance.RunInContext(
        scenario.Get<AllureContext>(), // Get the previously captured context
        () =>
        {
            // The test context required by the below methods wouldn't be
            // visible if they weren't wrapped with RunInContext.
            AllureLifecycle.Instance.StopTestCase();
            AllureLifecycle.Instance.WriteTestCase();
        }
    );
}

public static async Task Callee(ScenarioContext scenario)
{
    AllureLifecycle.Instance.StartTestCase(
        new(){ uuid = Guid.NewGuid().ToString() }
    );

    // Capture the context in an object of the test framework's object model
    scenario.Set(AllureLifecycle.Instance.Context);
}
