没有代码覆盖率的HttpParameterBinding
没有代码覆盖率的HttpParameterBinding
提问于 2019-06-06 23:38:13
OpenCover On Cake脚本未检测到将HttpPArameterBiding应用于某些ApiController操作参数的Owin.Testing使用覆盖率。
我已经创建了一种新类型的ApiController，作为我的ParameterBindingAttribute的一个动作，我称之为FromHeaderAttribute。之后，我创建了Owin Test Server和相应的HttpClient，并执行了请求和正确的断言，以验证绑定是否正常工作。测试成功通过。
这是我的单元测试蛋糕任务
Task("UnitTests")
.IsDependentOn("Build")
.IsDependentOn("RestoreNugets")
.DoesForEach(GetFiles($"{testsPath}/**/*.csproj"), (file) =>
{
var openCoverSettings = new OpenCoverSettings
{
OldStyle = true,
MergeOutput = true,
Register = "user",
LogLevel = OpenCoverLogLevel.Verbose,
ArgumentCustomization = args => args.Append("-coverbytest:*.Tests.dll").Append("-mergebyhash")
}
.WithFilter("+[AppRootName.*]*");
var projectName = file.GetFilename().ToString().Replace(".csproj",string.Empty);
var dotNetTestSettings = new DotNetCoreTestSettings
{
Configuration = "Release",
DiagnosticOutput = true,
Verbosity = DotNetCoreVerbosity.Normal,
ArgumentCustomization = (args)=>
{
args.Append($"--logger \"trx;LogFileName={projectName}-TestsResults.trx\"");
args.Append("--filter \"TestCategory=Unit|Category=Unit\"");
return args;
}
};
OpenCover(context => context.DotNetCoreTest(file.FullPath, dotNetTestSettings), new FilePath($"CoverageResults.xml"), openCoverSettings);
})
.Finally(()=>
{
Information($"Copying test reports to ${outputDir}/TestsResults .... ");
CopyFiles($"{testsPath}/**/TestResults/*.trx",$"{outputDir}/TestsResults");
ReportGenerator($"*-CoverageResults.xml", $"{outputDir}/Reports");
});这是我的XUnit测试：
[Fact]
[Trait("Category", "Unit")]
public async Task WhenHeadersArePresent_SettingsShouldBeSetted()
{
HttpConfiguration configuration = new HttpConfiguration();
var container = new SimpleInjector.Container();
Mock<IApiControllerValidation> mockValidationInterface = new Mock<IApiControllerValidation>();
ManualResetEvent resetEvent = new ManualResetEvent(false);
Settings settingsReceived = null;
mockValidationInterface.Setup((validator) => validator.Assert(It.IsAny<object>(), It.IsAny<object>(), It.IsAny<IDictionary<string, string>>(), It.IsAny<IHttpActionResult>()))
.Callback<object, object, IDictionary<string, string>, IHttpActionResult>((header, body, parameters, result) =>
{
settingsReceived = header as Settings;
resetEvent.Set();
});
container.RegisterInstance(mockValidationInterface.Object);
using (var server = TestServer.Create(app =>
{
configuration.DependencyResolver = new SimpleInjectorWebApiDependencyResolver(container);
configuration.MapHttpAttributeRoutes();
app.Use((owinContext, nextHandler)=> nextHandler());
app.UseWebApi(configuration);
}))
{
var client = server.HttpClient;
client.DefaultRequestHeaders.Add("header1", new List<string>() { "headervalue1" } );
client.DefaultRequestHeaders.Add("header2", new List<string>() { "headervalue2" });
var result = await client.PostAsync<Payload>("optionalHeader", new Payload("value1"), new JsonMediaTypeFormatter());
Assert.Equal(HttpStatusCode.OK,result.StatusCode);
};
resetEvent.WaitOne();
Assert.NotNull(settingsReceived);
Assert.Equal("headervalue1", settingsReceived.Header1);
Assert.Equal("headervalue2", settingsReceived.Header2);
}这是我的Api操作，我想测试我已经实现的FromHEader属性。
[HttpPost]
[Route("optionalHeader",Name = "PostValidation")]
public IHttpActionResult OptionalHeaders([FromHeader]Settings settings, [FromBody]Payload payload)
{
var result = Ok();
validation.Assert(settings,payload, null, result);
return result;
}我希望测试的代码覆盖率检测到此类型的使用，但这不是因为报告显示我的类型上的代码覆盖率为0。

我找出了问题所在，它与asp.net框架HttpParameterBinding组件无关。
而不是像这样执行代码封面：
OpenCover(context => context.DotNetCoreTest(file.FullPath, dotNetTestSettings), new FilePath($"CoverageResults.xml"), openCoverSettings);我将其更改为：
OpenCover(tool => {
tool.XUnit2($"{testsPath}/**/**/**/**/{projectName}.dll",xUnit2Settings);
}, new FilePath("./OpenCoverCoverageResults.xml"),openCoverSettings);此外，构建必须在调试模式下进行配置，以便OpenCover可以使用pdbs。
我唯一不喜欢的是dlls的路径是显式的层数，我也不想复制dlls，因为这会花费更多的时间。
