Allow test cases without namespace

[patricksadowski]

To reduce noise, work and maintenance we often use test classes without namespace in .NET. That leads to a test logger message Unable to parse one or more test names provided by your test runner. These will be logged using Namespace='UnknownNamespace', Type='UnknownType'. The entire test name will be used as the Method name. Please open a ticket so we can review this issue.

Would it be possible to allow test cases without namespace? Maybe it's impossible when considering nested classes.

.NET test project file

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <RootNamespace></RootNamespace>
  </PropertyGroup>
</Project>

Xunit test file

using Xunit;

public class ClassName
{
    [Fact]
    public void TestMethod()
    {
    }
}

JUnit Report

Current

<testsuites>
  <testsuite name="Assembly.dll" tests="1" skipped="0" failures="0" errors="0" time="1">
    <testcase classname="UnknownNamespace.UnknownType" name="ClassName.TestMethod" time="1" />
  </testsuite>
</testsuites>

Expected

<testsuites>
  <testsuite name="Assembly.dll" tests="1" skipped="0" failures="0" errors="0" time="1">
    <testcase classname="ClassName" name="TestMethod" time="1" />
  </testsuite>
</testsuites>
