Migrate Static to Wrapper

Perform mechanical, codemod-style replacement of static dependency call sites with calls to injected wrapper interfaces or built-in abstractions. Operates on a bounded scope (single file, project, or namespace) so migrations can be done incrementally.

When to Use

  • After wrappers have been generated (via generate-testability-wrappers) or built-in abstractions identified
  • Migrating DateTime.UtcNowTimeProvider.GetUtcNow() across a project
  • Migrating File.*IFileSystem.File.* across a namespace
  • Adding constructor injection for the new abstraction to affected classes
  • Incremental migration: one project or namespace at a time

When Not to Use

  • No wrapper or abstraction exists yet (use generate-testability-wrappers first)
  • The user wants to detect statics, not migrate them (use detect-static-dependencies)
  • The code does not use dependency injection and the user hasn't chosen ambient context
  • Migrating between test frameworks (use the appropriate migration skill)
