c# - 从代码运行xunit时如何设置testCase过滤器

问题描述

我正在尝试通过代码使用程序集运行器在 Xunit 中运行测试。

我的程序接受包含一组测试的 dll 文件名。

我需要从 dll 文件中运行一些特定的测试。我不是在看 Xunit 的类别实现。发现完成后需要接受测试用例。

public List<ITestCase> TestCases { get; } = new List<ITestCase>();

如何将不同的测试用例添加到列表中？

我希望我们需要在调用后进行过滤

private void OnDiscoveryComplete(DiscoveryCompleteInfo info) { }

但仅包含和DiscoveryCompleteInfo的 int 值。TestCasesToRunTestCasesDiscovered

如何为测试应用过滤器，以便在调用一次时根据过滤器执行测试OnDiscoveryComplete？

 public IList<TestResponse> ExecuteTest(string AutomationTestSuites)
 {
      try
      {
            _logger.LogInformation("Starting of the tests in {0} ", AutomationTestSuites);
            IEnumerable<Assembly> assembly = GetReferencingAssemblies(AutomationTestSuites);
            Assembly _assembly = assembly.Where(s => s.FullName.Contains(AutomationTestSuites)).FirstOrDefault();
            using (var runner = AssemblyRunner.WithoutAppDomain(_assembly.Location))
            {
                runner.OnDiscoveryComplete = OnDiscoveryComplete;
                runner.OnExecutionComplete = OnExecutionComplete;
                runner.OnTestFailed = OnTestFailed;
                runner.OnTestSkipped = OnTestSkipped;
                runner.OnTestPassed = OnTestPassed;
                _logger.LogInformation("Discovering Tests");
                //Runs the Xunit runner in parallel if parallel is set to True
                //If Max Parallel Threads is set to -1 there is no limit to number of threads for Xunit Runner
                runner.Start(parallel: true, maxParallelThreads: -1);

                finished.WaitOne();

                finished.Dispose();

            }

            return (testResponses);

      }
      catch(Exception ex)
      {
            _logger.LogError("Exeption in ExecuteTestFunctionality : ", ex);                return (testResponses);
      }
}

public static IEnumerable<Assembly> GetReferencingAssemblies(string assemblyName)
{
      var assemblies = new List<Assembly>();
      var dependencies = DependencyContext.Default.RuntimeLibraries;
      foreach (var library in dependencies)
      {
          if (IsCandidateLibrary(library, assemblyName))
          {
              var assembly = Assembly.Load(new AssemblyName(library.Name));
              assemblies.Add(assembly);
          }
       }
       return assemblies;
}
private static bool IsCandidateLibrary(RuntimeLibrary library, string assemblyName)
{
     return library.Name == assemblyName
          || library.Dependencies.Any(d => d.Name.StartsWith(assemblyName));
}

private void OnDiscoveryComplete(DiscoveryCompleteInfo info)
{
     _logger.LogInformation($"Running {info.TestCasesToRun} of {info.TestCasesDiscovered} tests...");

}

private void OnExecutionComplete(ExecutionCompleteInfo info)
{
    _logger.LogInformation($"Finished: {info.TotalTests} tests in {Math.Round(info.ExecutionTime, executionTimeRoundOff)}s ({info.TestsFailed} failed, {info.TestsSkipped} skipped)");
    finished.Set();
}

private void OnTestFailed(TestFailedInfo info)
{
    _logger.LogError("Test [FAILED] {0}: {1}", info.TestDisplayName, info.ExceptionMessage);
}
private void OnTestPassed(TestPassedInfo info)
{
    _logger.LogInformation("Test [Passed] : {0}", info.MethodName);
}
private void OnTestSkipped(TestSkippedInfo info)
{
    _logger.LogWarning("Test [SKIPPED] {0}: {1}", info.MethodName,info.SkipReason);
}

我需要从 dll 中过滤测试用例并仅运行选定的测试

解决方案

跑步者包含一个TestCaseFilter属性。

runner.TestCaseFilter = this.Filter;

/// <summary>
/// Filters the specified test case.
/// </summary>
/// <param name="testCase">The test case.</param>
/// <returns><c>true</c> if test case should be executed, <c>false</c> otherwise.</returns>
protected bool Filter(ITestCase testCase)
{
    if(testCase.TestMethod.TestClass.Class.Name.StartsWith("DoNotTest")) 
    {
        return false;
    }
        return true;
    }

您还可以使用该方法跟踪所有发现的测试用例。
