From 9db4cfd59322c20ad4f91b4405c5fafc6c2de2af Mon Sep 17 00:00:00 2001 From: Dan Date: Wed, 1 Apr 2026 01:08:00 -0700 Subject: [PATCH 001/120] Add mock generation for @Instantiable types MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit SafeDI now automatically generates `mock()` methods for every `@Instantiable` type, building full dependency subtrees with overridable closure parameters. New @SafeDIConfiguration properties: - `generateMocks: Bool` (default true) — controls mock generation - `mockConditionalCompilation: StaticString?` (default "DEBUG") — #if wrapping New @Instantiable parameter: - `mockAttributes: StaticString` — attributes for generated mock() (e.g. "@MainActor") Each mock gets a `SafeDIMockPath` enum with nested enums per dependency type, enabling callers to differentiate same-type dependencies at different tree paths. The build plugin now generates mock output files alongside DI tree files. Multi-module projects can add the plugin to all targets for per-module mocks.

Despite this design goal, there are a few key differences between projects that utilize SafeDI and projects that don’t. As the benefits of this system are clearly outlined in the [Features](../README.md#features) section above, this section outlines the pattern changes required to utilize a DI system like SafeDI. diff --git a/Examples/Example Package Integration/Package.swift b/Examples/Example Package Integration/Package.swift index 856ee656..06639856 100644 --- a/Examples/Example Package Integration/Package.swift +++ b/Examples/Example Package Integration/Package.swift @@ -52,6 +52,9 @@ let package = Package( swiftSettings: [ .swiftLanguageMode(.v6), ], + plugins: [ + .plugin(name: "SafeDIGenerator", package: "SafeDI"), + ], ), .target( name: "ChildBModule", @@ -63,6 +66,9 @@ let package = Package( swiftSettings: [ .swiftLanguageMode(.v6), ], + plugins: [ + .plugin(name: "SafeDIGenerator", package: "SafeDI"), + ], ), .target( name: "ChildCModule", @@ -74,6 +80,9 @@ let package = Package( swiftSettings: [ .swiftLanguageMode(.v6), ], + plugins: [ + .plugin(name: "SafeDIGenerator", package: "SafeDI"), + ], ), .target( name: "GrandchildrenModule", @@ -84,6 +93,9 @@ let package = Package( swiftSettings: [ .swiftLanguageMode(.v6), ], + plugins: [ + .plugin(name: "SafeDIGenerator", package: "SafeDI"), + ], ), .target( name: "SharedModule", @@ -91,6 +103,9 @@ let package = Package( swiftSettings: [ .swiftLanguageMode(.v6), ], + plugins: [ + .plugin(name: "SafeDIGenerator", package: "SafeDI"), + ], ), ], ) diff --git a/Examples/ExamplePrebuiltPackageIntegration/Package.swift b/Examples/ExamplePrebuiltPackageIntegration/Package.swift index 7e514eff..153e73ce 100644 --- a/Examples/ExamplePrebuiltPackageIntegration/Package.swift +++ b/Examples/ExamplePrebuiltPackageIntegration/Package.swift @@ -52,6 +52,9 @@ let package = Package( swiftSettings: [ .swiftLanguageMode(.v6), ], + plugins: [ + .plugin(name: "SafeDIPrebuiltGenerator", package: "SafeDI"), + ], ), .target( name: "ChildBModule", @@ -63,6 +66,9 @@ let package = Package( swiftSettings: [ .swiftLanguageMode(.v6), ], + plugins: [ + .plugin(name: "SafeDIPrebuiltGenerator", package: "SafeDI"), + ], ), .target( name: "ChildCModule", @@ -74,6 +80,9 @@ let package = Package( swiftSettings: [ .swiftLanguageMode(.v6), ], + plugins: [ + .plugin(name: "SafeDIPrebuiltGenerator", package: "SafeDI"), + ], ), .target( name: "GrandchildrenModule", @@ -84,6 +93,9 @@ let package = Package( swiftSettings: [ .swiftLanguageMode(.v6), ], + plugins: [ + .plugin(name: "SafeDIPrebuiltGenerator", package: "SafeDI"), + ], ), .target( name: "SharedModule", @@ -91,6 +103,9 @@ let package = Package( swiftSettings: [ .swiftLanguageMode(.v6), ], + plugins: [ + .plugin(name: "SafeDIPrebuiltGenerator", package: "SafeDI"), + ], ), ], ) diff --git a/Plugins/SafeDIGenerator/SafeDIGenerateDependencyTree.swift b/Plugins/SafeDIGenerator/SafeDIGenerateDependencyTree.swift index 2dd5d96d..6910a7e6 100644 --- a/Plugins/SafeDIGenerator/SafeDIGenerateDependencyTree.swift +++ b/Plugins/SafeDIGenerator/SafeDIGenerateDependencyTree.swift @@ -62,6 +62,7 @@ struct SafeDIGenerateDependencyTree: BuildToolPlugin { projectRoot: packageRoot, outputDirectory: outputDirectory, manifestFile: manifestFile, + targetSwiftFiles: targetSwiftFiles, ) guard !outputFiles.isEmpty else { return [] diff --git a/Plugins/SafeDIPrebuiltGenerator/SafeDIGenerateDependencyTree.swift b/Plugins/SafeDIPrebuiltGenerator/SafeDIGenerateDependencyTree.swift index 8d94e721..374f1767 100644 --- a/Plugins/SafeDIPrebuiltGenerator/SafeDIGenerateDependencyTree.swift +++ b/Plugins/SafeDIPrebuiltGenerator/SafeDIGenerateDependencyTree.swift @@ -62,6 +62,7 @@ struct SafeDIGenerateDependencyTree: BuildToolPlugin { projectRoot: packageRoot, outputDirectory: outputDirectory, manifestFile: manifestFile, + targetSwiftFiles: targetSwiftFiles, ) guard !outputFiles.isEmpty else { return [] diff --git a/Plugins/SharedRootScanner.swift b/Plugins/SharedRootScanner.swift index 70e515e9..00c80f18 100644 --- a/Plugins/SharedRootScanner.swift +++ b/Plugins/SharedRootScanner.swift @@ -40,10 +40,18 @@ func runRootScanner( projectRoot: URL, outputDirectory: URL, manifestFile: URL, + targetSwiftFiles: [URL]?

This ensures that transitive overrides for @Instantiated deps flow through the tree correctly. e.g., ChildA(grandchildAA: grandchildAA, grandchildAB: grandchildAB) instead of ChildA.mock() which dropped the parent's overrides. Finding 2: sanitizeForIdentifier converts type names like Container to valid Swift identifiers (Container__Bool) for SafeDIMockPath enum names and parameter labels.

Child(@Received(fulfilledByDependencyNamed:"user", ofType:User.self) let userType: UserType) now correctly threads the parent's `user` variable. P2: Also detect `class func mock(...)` in addition to `static func mock`. Manual clarifies that detection is limited to the decorated declaration body.

The mock code path reuses the same recursive tree structure as the dependency tree, with the only difference being the `let` binding line which wraps with an override closure: `let x = x?(.pathCase) ?? `. This eliminates the parallel flat-dictionary implementation that kept rediscovering bugs (scoping, aliases, extension types, forwarded props, fulfilling types) that ScopeGenerator already handles correctly. Key changes: - Add CodeGeneration enum (.dependencyTree, .mock) threaded through generateCode/generateProperties - Add generateMockRootCode for the .root case in mock mode - Add collectMockDeclarations to walk tree for SafeDIMockPath enum - Update DependencyTreeGenerator.generateMockCode to use ScopeGenerator trees instead of MockGenerator - Delete MockGenerator.swift (1043 lines) - Update all 56 mock test expectations to match new output format Co-Authored-By: Claude Opus 4.6 (1M context) --- .../Generators/DependencyTreeGenerator.swift | 81 +- .../SafeDICore/Generators/MockGenerator.swift | 1043 ----------------- .../Generators/ScopeGenerator.swift | 787 ++++++++++--- Sources/SafeDITool/SafeDITool.swift | 2 +- .../SafeDIToolMockGenerationTests.swift | 545 +++++---- 5 files changed, 969 insertions(+), 1489 deletions(-) delete mode 100644 Sources/SafeDICore/Generators/MockGenerator.swift diff --git a/Sources/SafeDICore/Generators/DependencyTreeGenerator.swift b/Sources/SafeDICore/Generators/DependencyTreeGenerator.swift index 32f6e765..5b0fcdbc 100644 --- a/Sources/SafeDICore/Generators/DependencyTreeGenerator.swift +++ b/Sources/SafeDICore/Generators/DependencyTreeGenerator.swift @@ -77,26 +77,71 @@ public actor DependencyTreeGenerator { /// Generates mock code for all `@Instantiable` types. public func generateMockCode( mockConditionalCompilation: String?, -

Parameter label disambiguation: When two properties at different tree depths share the same init label (e.g., both have `let service:`), the mock parameters are disambiguated with a type suffix (e.g., `service_ServiceA`, `service_ServiceB`). 2. Path extension: Grandchild path case names now correctly reflect their parent scope (e.g., `.childA` instead of `.root`), matching the tree position where each dependency is constructed. 3. onlyIfAvailable mock support: @Received(onlyIfAvailable: true) deps are now exposed as optional mock parameters so users can provide them. If not provided, nil is passed. Previously these were silently dropped.

This ensures transitive deps are properly constructed and threaded through the mock, rather than generating naive no-arg constructors. Received deps are only promoted to children when their type isn't already constructed by an ancestor, so types like `@Received let shared` that are satisfied by a sibling `@Instantiated let shared` are resolved naturally through scope rather than duplicated. - Remove asMockRoot, generateMockCodeAsMockRoot, collectAllDescendants from ScopeGenerator (no longer needed) - Remove separate received dep binding generation from generateMockRootCode (now handled by the tree) -

Uncovered Instantiator/ErasedInstantiator dependencies used the inner type (e.g., ErrorInterceptor) instead of the full wrapper type (e.g., SendableInstantiator) for the mock parameter. Now uses the property's actual type for non-constant properties. 2. When multiple properties share the same type but have different labels (e.g., installScopedDefaultsService and userScopedDefaultsService both typed UserDefaultsService), only the first got a mock parameter. Now each unique parameter label within an enum name group gets its own parameter.

For example, AnyUserService is a concrete existential wrapper not itself @Instantiable, but its underlying DefaultUserService IS @Instantiable and in the type map. Now typeDescriptionToFulfillingInstantiableMap is the sole authority for "can we construct this type?" — if it's in the map, the mock parameter is optional with a default construction. If not, it's a required @escaping parameter. Also includes swiftformat lint fixes.

Remove knownInstantiableTypes filter — typeDescriptionToFulfillingInstantiableMap is the sole authority for constructibility. Types in the map get optional parameters with defaults. Types not in the map get required parameters. 2. Build erasedToConcreteTypeMap to resolve concrete existential wrappers (e.g., AnyUserService wrapping DefaultUserService). When a received dependency's type isn't in the type map but IS a concrete existential wrapper, resolve to the underlying concrete type and construct with wrapping (e.g., AnyUserService(DefaultUserService())). This fixes the regression where NoteView.mock(userName:) required userService and stringStorage parameters that should be optional.

This fixes scoping bugs where shared dependencies were constructed inside nested functions and invisible to sibling scopes. Key changes: - Add forMockGeneration parameter to Scope.createScopeGenerator that forces empty unavailableOptionalProperties and skips eager code gen - Add createMockTypeDescriptionToScopeMapping that builds Scopes for all types (not just reachable from roots), promoting @Received dependencies as .instantiated entries with concrete existential resolution - Rewrite createMockRootScopeGenerator to use Scope-based tree - Delete createMockChildScopeGenerators (~90 lines) - Fix erasedToConcreteExistential wrapping in mock constant bindings so the ?? operator has matching types The production orderedPropertiesToGenerate topological sort now handles mock ordering correctly — shared dependencies are constructed at the right scope level before all types that need them.

Instead they bubble up through receivedProperties and are promoted at the root scope only via collectTransitiveReceivedProperties. This ensures shared dependencies are constructed at root scope where all nested functions can access them, matching the production dependency tree's scoping. Also fixes erasedToConcreteExistential wrapping in mock constant bindings — the ?? operator now has matching types when the default construction wraps a concrete type in an existential wrapper.

Now iterates: promote unsatisfied received dependencies, rebuild the ScopeGenerator, check for new unsatisfied dependencies from the newly promoted children, repeat until stable. Also adds test for transitive protocol dependency fulfilled by extension-based type (StringStorage fulfilled by SomeExternalType).

LoggedInViewController: Remove duplicate userManager parameter. @Forwarded userManager satisfies all @Received userManager dependencies in the tree — it should NOT also appear as a promoted closure parameter. StringStorage: Change from @escaping (required) to optional with default. StringStorage protocol IS fulfilled by SomeExternalType via fulfillingAdditionalTypes — the scope map should resolve it. Both tests now define the CORRECT expected output. Code fixes needed to make them pass (tracked in mock_audit_issues.md).

Default() fallback. They become optional mock parameters with no default — evaluating to nil when not provided. The closure return type is optional (e.g., -> A? not -> A). 2. Forwarded properties no longer collide with promoted received dependencies. Both createMockRootScopeGenerator and generateMockRootCode now filter out forwarded properties from the promotion/uncovered scans. ScopeData.root has empty forwardedProperties, so receivedProperties doesn't subtract them — we filter explicitly instead. 3. Iterative promotion loop restored (with onlyIfAvailable + forwarded filtering) to handle multi-level transitive chains where each promotion round reveals new unsatisfied dependencies.

Tests added: - mock_noRedeclarationWhenOnlyIfAvailableDepAppearsInMultipleChildren (PASSES) - mock_noUseBeforeDeclarationWhenReceivedDepPromotedFromDeepTree (PASSES) - mock_noRedeclarationWhenSameDepIsReceivedAndOnlyIfAvailable (FAILS) Root cause: config: Config (non-optional, required) and config: Config? (optional, onlyIfAvailable) are different Properties. Promoting the non-optional doesn't satisfy the optional. Need to treat optional received properties as satisfied when their unwrapped form is promoted. - mock_erasedToConcreteExistentialWithChildrenWrapsInMockBinding (PASSES) Also improves onlyIfAvailable detection: checks type is Optional rather than unwrapped-form matching, preventing false positives where a required non-optional dep shares the same unwrapped form.

(optional, onlyIfAvailable) from a different child was not being satisfied — producing a duplicate let binding. Fix: in ScopeGenerator.receivedProperties computation, filter out optional properties whose unwrapped form is in propertiesToDeclare. This correctly treats the non-optional promoted version as satisfying both the required and optional receivers. Also fixes stale test expectation for onlyIfAvailable Root mock.

Two fixes: 1. Skip optional received properties when a non-optional version with the same label exists — the non-optional subsumes it (Swift auto-wraps for optional paths). 2.

A nested child's `service: InternalService` would incorrectly suppress the root's uncovered `service: ExternalService`. Two fixes: 1. Only root-level tree declarations suppress uncovered root dependencies (filter by pathCaseName == "root") 2.

Remove redundant `.aliased` case from collectReceivedProperties' propertiesToGenerate loop — the own-dependency union unconditionally adds the same fulfilling property, making the child-path subtraction redundant. 2. Store exact properties (not unwrapped) in collectReceivedProperties' onlyIfAvailable set. This correctly handles aliased dependencies where the fulfilling type is non-optional but onlyIfAvailable. Subtraction now uses unwrapped comparison so a declared `x: X` still satisfies an onlyIfAvailable `x: X?`. 3. Fix isOnlyIfAvailable check in generateMockRootCode to handle non-optional aliased onlyIfAvailable properties. When a non-optional property has no Optional counterpart (ruling out collision with a required version), check onlyIfAvailableUnwrappedReceivedProperties directly.
