Migrate snapshot package references

The original combined XBullet.EasyTesting.Snapshots package is now a compatibility facade over a framework-independent core package and an outbound HTTP adapter package. Public types keep the XBullet.EasyTesting.Snapshots namespace.

Choose the replacement

Existing usage Package for new projects
Values, raw JSON, text, HTTP content, controller responses, or HttpExchangeRecorder XBullet.EasyTesting.Snapshots.Core
Requests or exchanges from StubHttpMessageHandler XBullet.EasyTesting.Snapshots.Http
Both groups XBullet.EasyTesting.Snapshots.Http already references core

The split is verified by forwarded public types and dependency boundaries:

[Fact]
public void Compatibility_facade_forwards_to_split_snapshot_assemblies()
{
    var facade = System.Reflection.Assembly.Load("XBullet.EasyTesting.Snapshots");
    var forwardedTypes = facade.GetForwardedTypes();

    Assert.Contains(typeof(SnapshotAssert), forwardedTypes);
    Assert.Contains(typeof(SnapshotLocationContext), forwardedTypes);
    Assert.Contains(typeof(ControllerSnapshotOptionsDefaults), forwardedTypes);
    Assert.Contains(typeof(StubHttpRequestSnapshot), forwardedTypes);
    Assert.Contains(typeof(StubHttpExchangeSnapshot), forwardedTypes);
    Assert.Contains(typeof(HttpExchangeRecorder), forwardedTypes);
    Assert.Contains(typeof(HttpExchangeFailureSnapshot), forwardedTypes);
    Assert.Contains(typeof(HttpExchangeSnapshotFormat), forwardedTypes);
    Assert.Contains(typeof(HttpExchangeSnapshotOptionsDefaults), forwardedTypes);
    Assert.Equal(
        "XBullet.EasyTesting.Snapshots.Core",
        typeof(SnapshotAssert).Assembly.GetName().Name);
    Assert.Equal(
        "XBullet.EasyTesting.Snapshots.Http",
        typeof(StubHttpRequestSnapshot).Assembly.GetName().Name);

    var coreReferences = typeof(SnapshotAssert).Assembly
        .GetReferencedAssemblies()
        .Select(reference => reference.Name)
        .ToArray();
    Assert.DoesNotContain("XBullet.EasyTesting.Http", coreReferences);
    Assert.DoesNotContain("XBullet.EasyTesting", coreReferences);
}

Core has no dependency on XBullet.EasyTesting, ASP.NET testing, or XBullet.EasyTesting.Http. This keeps non-HTTP snapshot projects lightweight.

Migrate a project

For core-only usage:

dotnet remove package XBullet.EasyTesting.Snapshots
dotnet add package XBullet.EasyTesting.Snapshots.Core

For outbound HTTP stub snapshots:

dotnet remove package XBullet.EasyTesting.Snapshots
dotnet add package XBullet.EasyTesting.Snapshots.Http

Then restore, build, and run the snapshot suite on every target framework. Source changes are normally unnecessary because namespaces and public APIs remain stable. Existing verified files do not need renaming solely because of the package split.

If a transitive dependency previously supplied the combined package, add the specific replacement directly to the test project so its snapshot capability is explicit.

Stay on the facade temporarily

Existing projects may retain XBullet.EasyTesting.Snapshots. The facade references both split packages and forwards their public types, preserving binary compatibility. It remains useful for a staged migration, but it also keeps the outbound HTTP dependency graph even when only core snapshots are used.

Do not mix facade and specific package versions arbitrarily. Keep all XBullet snapshot packages on the same release version to avoid assembly-resolution surprises.

Verify.Xunit is separate

XBullet.EasyTesting.Verify.Xunit is not a replacement assembly for the built-in engine; it is an optional adapter to Verify.Xunit v3. Its acceptance workflow and verified-file format remain owned by Verify. See choose an engine.

The API package index identifies the canonical reference page for each implementation package and the compatibility facade.
