如何在dotnetcore xunit测试中设置文化

我有以下单元测试我将.Net Framework库移植到.Net核心xunint测试库。需要添加单元测试的项目是

正在添加到所选文件中,如此处所示

我想添加的单元测试是

[Test]
public void ParsingWithCommaDecimalSeparatorShouldWork()
{
    var ci = new CultureInfo(CultureInfo.CurrentCulture.Name)
             {
                 NumberFormat =
                 {
                     NumberDecimalSeparator = ","
                     , NumberGroupSeparator = "."
                 }
             };
    Thread.CurrentThread.CurrentCulture = ci;

    var t = Template.Parse("{{2.5}}");
    var result = t.Render( new Hash(), CultureInfo.InvariantCulture );
    Assert.AreEqual( result, "2.5"   );
}

然而,测试无法在dotnet核心中编译。

  

严重级代码描述项目文件行抑制状态   错误CS1061“线程”不包含的定义   'CurrentCulture'并没有扩展方法'CurrentCulture'接受a   可以找到'Thread'类型的第一个参数(你错过了吗?   使用指令或程序集   引用?)DotLiquid.Tests(net451)C:\ Users \ phelan \ workspace \ dotliquid \ src \ DotLiquid.Tests \ OutputTests.cs 113 N / A

我需要对不同的文化进行不同的单元测试。我想创建一个XUnit理论,其中每个实例都在不同的文化中传递单元测试以进行验证。这是如何在.NetCore中完成的?

我查看了一些dotnet source,我找到了这个。

CultureInfo.DefaultThreadCurrentCulture = ci;

基本上,您可以从CultureInfo的静态属性设置默认线程当前区域性,而不是从Thread.CurrentThread

我发现了this

public CultureInfo CurrentCulture
{
    get
    {
        Contract.Ensures(Contract.Result<CultureInfo>() != null);
        return CultureInfo.CurrentCulture;
    }

    set
    {
        Contract.EndContractBlock();

        // If you add more pre-conditions to this method, check to see if you also need to 
        // add them to CultureInfo.DefaultThreadCurrentCulture.set.

        if (m_CurrentCulture == null && m_CurrentUICulture == null)
            nativeInitCultureAccessors();

        CultureInfo.CurrentCulture = value;
    }
}

这是Thread.cs。因此,您可以明确设置CultureInfo.CurrentCulture属性。

示例:

CultureInfo.CurrentCulture = new CultureInfo("en-GB"); ;

Assert.Equal("£1,000.00", String.Format("{0:C}", 1000));

CultureInfo.CurrentCulture = new CultureInfo("en-US"); ;

Assert.Equal("$1,000.00", String.Format("{0:C}", 1000));

单元测试项目的csproj文件:

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <TargetFramework>netcoreapp1.0</TargetFramework>

    <IsPackable>false</IsPackable>

    <ApplicationIcon />

    <OutputType>Library</OutputType>

    <StartupObject />
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.NET.Test.Sdk" Version="15.3.0-preview-20170425-07" />
    <PackageReference Include="xunit" Version="2.2.0" />
    <PackageReference Include="xunit.runner.visualstudio" Version="2.2.0" />
  </ItemGroup>

</Project>

解决方案是设置

CultureInfo.DefaultThreadCurrentCulture = ci;

然后启动新线程。这将为下一个线程设置当前文化。最后的测试案例是。

[Test]
public void ParsingWithCommaDecimalSeparatorShouldWork()
{
    var ci = new CultureInfo(CultureInfo.CurrentCulture.Name)
             {
                 NumberFormat =
                 {
                     NumberDecimalSeparator = ","
                     , NumberGroupSeparator = "."
                 }
             };

    CultureInfo.DefaultThreadCurrentCulture = ci;
    var result = "";
    var thread = new Thread
        ( delegate()
        {
            Console.WriteLine(CultureInfo.CurrentCulture.NumberFormat.NumberDecimalSeparator);
            Console.WriteLine(CultureInfo.CurrentCulture.NumberFormat.NumberGroupSeparator);

            var t = Template.Parse("{{2.5}}");
            result = t.Render(new Hash(), CultureInfo.InvariantCulture);
        } );
    thread.Start();
    thread.Join();
    Assert.AreEqual(result, "2.5");

}

这有点乱,但完成工作。
