Summary

TUnit.Engine/Helpers/DisplayNameBuilder.cs allocated a fresh StringBuilder per call in both FormatArguments overloads. This runs for every data-driven test row when building display names.

This routes both overloads through the existing TUnit.Core.Helpers.StringBuilderPool (already present in the codebase, already accessible via InternalsVisibleTo), reusing pooled builders instead of allocating new ones. A try/finally guarantees the builder is returned even if ArgumentFormatter.Format throws.

Behavior is identical — same output, same formatting.

Testing

  • dotnet build TUnit.Engine -c Release -f net10.0 succeeds (0 warnings, 0 errors).

Closes #6028

Review: perf(engine): pool StringBuilder in DisplayNameBuilder.FormatArguments

The change is correct and consistent with how StringBuilderPool is already used elsewhere in the codebase (e.g., TestContext.Metadata.cs, TestContextExtensions.cs). The try/finally pattern guarantees the builder is returned even on exception, which is the right approach.

Minor nit: unused using System.Text;

After this change, StringBuilder is no longer directly referenced in DisplayNameBuilder.cs — it's now only accessed indirectly through StringBuilderPool. The using System.Text; at line 2 is now unused and can be removed.

// Line 2 — can be dropped
using System.Text;

Broader observation: StringBuilderPool has no pool-size cap

The custom StringBuilderPool uses an unbounded ConcurrentBag<StringBuilder>. If many threads call FormatArguments concurrently (e.g., during parallelised test discovery) and all builders fit within MaxCapacity, they will all be returned and none evicted. In practice this is unlikely to be a problem for a test runner, but it is worth noting if the pool is extended to other hot paths.

The BCL's Microsoft.Extensions.ObjectPool.ObjectPool<T> (available since .NET 6, and already in the dependency graph if Microsoft.Extensions.ObjectPool is referenced) or the simpler pattern of capping Pool.Count before adding would bound memory. That said, given the current usage profile this is a pre-existing design choice unrelated to this PR — no action required here.

Overall

The change is a clean, well-scoped performance improvement. The logic and safety pattern are correct, and it aligns perfectly with the existing pool usage in the codebase. The only actionable item is the now-redundant using System.Text; import.

Follow-up Review

Checking against the previous review comment: the one actionable item — removing the now-unused using System.Text;is already handled in this PR's diff (line 2 is removed). No outstanding items remain from the previous round.

Current state assessment

The change is correct and complete:

  • Both FormatArguments overloads now use StringBuilderPool.Get() / StringBuilderPool.Return() wrapped in try/finally.
  • The using System.Text; import is dropped (since StringBuilder is no longer directly referenced).
  • StringBuilderPool.Return already guards against retaining oversized builders (Capacity > MaxCapacity = 1024), so the pool will not retain pathologically large instances.
  • The behavior is identical to before — only allocation profile changes.

One minor observation (non-blocking)

The two overloads are now structurally identical except for the formatters argument passed to ArgumentFormatter.Format. They could be unified into a single method:

public static string FormatArguments(object?[] arguments, List<Func<object?, string>>? formatters = null)
{
    if (arguments.Length == 0)
        return string.Empty;

    var sb = StringBuilderPool.Get();
    try
    {
        for (var i = 0; i < arguments.Length; i++)
        {
            if (i > 0)
                sb.Append(", ");
            sb.Append(ArgumentFormatter.Format(arguments[i], formatters ?? []));
        }
        return sb.ToString();
    }
    finally
    {
        StringBuilderPool.Return(sb);
    }
}

This would eliminate the duplication entirely and make future changes to the formatting logic a single-site edit. However, this is a pre-existing duplication — not introduced by this PR — so it is perfectly reasonable to leave it for a separate cleanup if desired.

Overall

The PR is a clean, well-scoped performance improvement. The logic, safety pattern, and import cleanup are all correct. Ready to merge.
