Test Cases With Strings That Contain the Pipe Character are Not Run

[JasonBock]

To Reproduce

• Create a new project that targets .NET 10. Specifically, ensure the project file has this setup:

<Project Sdk="Microsoft.NET.Sdk">
	<PropertyGroup>
		<EnableNUnitRunner>true</EnableNUnitRunner>
		<LangVersion>latest</LangVersion>
		<TargetFramework>net10.0</TargetFramework>
		<TestingPlatformDotnetTestSupport>true</TestingPlatformDotnetTestSupport>
		<ImplicitUsings>enable</ImplicitUsings>
		<Nullable>enable</Nullable>
	</PropertyGroup>
	<ItemGroup>
		<PackageReference Include="Microsoft.NET.Test.Sdk" Version="18.0.1" />
		<PackageReference Include="NUnit" Version="4.4.0" />
		<PackageReference Include="NUnit.Analyzers" Version="4.11.2">
			<PrivateAssets>all</PrivateAssets>
			<IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
		</PackageReference>
		<PackageReference Include="NUnit3TestAdapter" Version="6.1.0" />
	</ItemGroup>
</Project>

• Add a test to the project:

using NUnit.Framework;

namespace NUnitIssue;

public static class TestIssue
{
    [TestCase("This | That", false)]
    public static void TestLength(string input, bool expected) =>
        Assert.That(input.Length % 2 == 0, Is.EqualTo(expected));
}

Expected

The test runs and passes.

Actual

The test doesn't run at all.

Commentary

If I remove the | character, it runs. This is similar to another issue I reported, which is fixed, but a pipe character still seems to cause the runner to ignore it.

Just checked the code, had to add a a global.json with the testplatform,

It works on cmd line

but not in Test Explorer:

When using the Test Explorer, a test filter is created and that fails:

 <filter><test>NUnitIssue.TestIssue.TestLength(&quot;This </test></filter>
