UseProjectRelative + SourceFileRelativeDirectory

[snebjorn]

Is the feature request related to a problem

ProjectRelative snapshots folder quickly becomes unwieldy.

Describe the solution

I think it would be easier to reason about what snapshots are orphaned if files inside the ProjectRelativeDirectory would be nested in folders that mirrored the path of the source.

example:

Root
├── Tests
│   └── Foo
│       └── FooTests.cs
└── Snapshots
    └── Foo
        └── FooTests.Bar.verified.json

Additional context

This accomplishes the above. But would be nice with built-in support 😄

/// <param name="testsDirectoryName">

private static void UseMirroredSnapshotDirectories(
    string snapshotsDirectoryName,
    string testsDirectoryName
) =>
    Verifier.DerivePathInfo(
        (sourceFile, projectDirectory, type, method) =>
        {
            var testsDirectory = Path.Combine(projectDirectory, testsDirectoryName);
            var sourceDirectory = Path.GetDirectoryName(sourceFile)!;
            var relativeDirectory = Path.GetRelativePath(testsDirectory, sourceDirectory);

            var snapshotDirectory =
                relativeDirectory.StartsWith("..", StringComparison.Ordinal)
                    ? Path.Combine(projectDirectory, snapshotsDirectoryName)
                : relativeDirectory == "."
                    ? Path.Combine(projectDirectory, snapshotsDirectoryName)
                : Path.Combine(projectDirectory, snapshotsDirectoryName, relativeDirectory);

            return new(
                directory: snapshotDirectory,
                typeName: type.Name,
                methodName: method.Name
            );
        }
    );

why would you want the output of a test so far removed from the actual test?

[snebjorn]

I essentially don't care about it after I've approved it. I think about it as a test artifact 😄
That why I UseProjectRelativeDirectory. But cleaning up orphans during a refactor became unwieldy.
