我有一个带有xUnit的.NET Core项目。我不能再使用Resharper进行任何测试了。即使非常简单的测试也是不确定的。 e.g：
using Xunit;
public class MyTests
{
[Fact]
public void MySuperTest()
{
Assert.Equal(1, 1);
}
}
输出日志显示异常：

我的Nuget导入是：
<ItemGroup>
<PackageReference Include="Microsoft.Extensions.DependencyModel" Version="1.1.2" />
<PackageReference Include="Microsoft.NET.Test.Sdk" Version="15.0.0" />
<PackageReference Include="Microsoft.NETCore.Portable.Compatibility" Version="1.0.1" />

<PackageReference Include="System.ServiceModel.Http" Version="4.3.0" />
<PackageReference Include="xunit" Version="2.2.0" />
<PackageReference Include="xunit.runner.console" Version="2.2.0" />
</ItemGroup>
答案 0 :(得分：9)
错误在于我选择要导入的Nuget包。
而不是：
<PackageReference Include="xunit.runner.console" Version="2.2.0" />
我应该有：
<PackageReference Include="xunit.runner.visualstudio" Version="2.2.0" />
在此之后，您可能需要重建或关闭Visual Studio。
答案 1 :(得分：1)
对我而言，我的xUnit测试不会在.NET核心2.0测试项目中运行的原因完全不同。
我看到的错误如下：
Cause: System.InvalidOperationException: Test-cases are missing for the selected tests. Rebuild the project and try again.
和
// Display Fields using WooCommerce Action Hook
add_action( 'woocommerce_product_options_discount_info', 'wc_general_product_data_custom_field' );
function wc_general_product_data_custom_field() {
// Number Field
woocommerce_wp_text_input( array(
'id' => '_discount_info',
'label' => __( 'Discount %', 'woocommerce' ),
'desc_tip' => 'true',
'description' => __( 'Enter the % discount here.', 'woocommerce' ),
'type' => 'number',
'custom_attributes' => array(
'min' => '1',
'step' => '1',
),
) );
}
// Hook to save the data value from the custom fields
add_action( 'woocommerce_process_product_meta', 'wc_save_general_proddata_custom_field' );
/** Hook callback function to save custom fields information */
function wc_save_general_proddata_custom_field( $post_id ) {
// Save Number Field
$number_field = isset( $_POST['_discount_info'] ) ? $_POST['_discount_info'] : '';
if( ! empty( $number_field ) ) {
update_post_meta( $post_id, '_discount_info', $number_field );
}
}
这是由测试类构造函数中的一些失败代码引起的（我正在为.NET核心2.0连接一些用户机密）。修复此代码后，我就可以从ReSharper测试运行器运行测试。
答案 2 :(得分：0)
将Resharper更新到最新版本（2020.2）可以帮助我进行测试，
