如何在AllureApi.Step中设置Allure报告的结果？

Question

我的基类中有以下代码，用于所有 Allure 支持的测试：

[AllureNUnit]
internal abstract class PageTestBase : Microsoft.Playwright.NUnit.PageTest
{
    protected async Task Step(string name, Func<Task> action)
    {
        try
        {
            await AllureApi.Step(name, action);
        }
        catch (Exception)
        {
            //save screenshot in case something goes wrong (mandatory)
            await Page.ScreenshotAsync(new() { Path = "failure.png" });
            //TODO: set result to failed 
        }

        //TODO: depending on settings user can opt to save screenshots after every step
        await Page.ScreenshotAsync(new() { Path = "AfterEachStep.png" });
    }
}

我希望能够创建一个步骤抽象，允许在步骤完成后做出反应（即失败后截取屏幕截图，并可选择在每个步骤后截取屏幕截图）。如何在 Allure.NUnit 中实现这一点？

对我有用的解决方案是从 Allure 复制一些代码并对其进行自定义，以便创建适当的状态机：

public Task UiStep(string name, Func<Task> action) =>
    ExecuteStepAsync(name, async () =>
    {
        await action();
        return Task.FromResult<object?>(null);
    });

/// <summary>
/// Executes the asynchronous function and reports the result as a new step
/// of the current fixture, test or step. Requires one of these contexts to
/// be active.
/// </summary>
/// <param name="name">The name of the step.</param>
/// <param name="function">The asynchronous function to run.</param>
/// <returns>The original value returned by the function.</returns>
public Task<T> UiStep<T>(string name, Func<Task<T>> function) => ExecuteStepAsync(name, function);

private async Task<T> ExecuteStepAsync<T>(string name, Func<Task<T>> action)
{
    T result;
    Exception? error = null;
    ExtendedApi.StartStep(name);
    try
    {
        result = await action();
    }
    catch (Exception e)
    {            
        error = e;
        await SaveScreenshot(Page, _reportingSettings.FailureScreenshots, name);
        throw;
    }
    finally
    {
        ExtendedApi.ResolveStep(error);
        await SaveScreenshot(Page, _reportingSettings.EveryStepScreenshots, name);
    }
    return result;
}
