Question

我正在尝试使用nunits测试引擎/测试运行器来运行特定的测试，但不知怎的，我无法让过滤器工作（如果我使用空过滤器，它会运行我的测试）。

这是到目前为止的代码：

        var package = new TestPackage("path/to/dll");
        package.AddSetting("WorkDirectory", Path.GetDirectoryName("path/to/dll"));

        using (ITestEngine engine = TestEngineActivator.CreateInstance())
        {
            engine.WorkDirectory = Path.GetDirectoryName(dllPath);
            using (NUnit.Engine.ITestRunner runner = engine.GetRunner(package))
            {
                var filter = new TestFilter("<filter><tests><test>UnitTestProject2.UnitTest1.TestMethod1</test></tests></filter>");
                var result = runner.Run(new TestEventDispatcher(), filter);
                runner.Unload();
                return CreateResult(result);
            }
        }

如果我尝试运行此代码并检查结果，我会得到：

        <command-line><![CDATA[".." ]]></command-line><filter><tests><test>UnitTestProject2.UnitTest1.TestMethod1</test></tests></filter><test-suite type="Assembly" id="0" name="UnitTestProject2.dll" fullname="...dll" runstate="NotRunnable" testcasecount="1" result="Failed" label="Error" start-time="2018-02-20 20:31:57Z" end-time="2018-02-20 20:31:57Z" duration="0.001" total="1" passed="0" failed="1" inconclusive="0" skipped="0" asserts="0"><failure><message><

我错过了一些明显的东西吗？我在这里阅读文档，听起来应该是正确的方法：https://github.com/nunit/docs/wiki/Test-Filters

使用没有<tests>节点的过滤器，即：

<filter><test>UnitTestProject.Class1.Test123</test></filter>

对于多项测试，请使用：

<filter><or><test>NUnitTestRunner.Class1.Test123</test><test>NUnitTestRunner.Class1.Test456</test></or></filter>

或者，您可以使用ITestFilterBuilder：

示例：

using (ITestEngine engine = TestEngineActivator.CreateInstance())
{
    var filterService = engine.Services.GetService<ITestFilterService>();
    var builder = filterService.GetTestFilterBuilder();
    builder.AddTest("UnitTestProject.Class1.Test123");
    var filter = builder.GetFilter();

    using (ITestRunner runner = engine.GetRunner(package))
    {
        var result = runner.Run(listener: null, filter: filter);
    }
}

两种解决方案都通过了测试：total="1" passed="1"

将NUnit TestRunner与xml过滤器一起使用
