PR Review: Migrating V2 Regression Cases

I've completed a thorough review of this PR that migrates 7 regression test cases from v2 to v3. Overall, this is a solid migration with good test structure and necessary infrastructure improvements.

Review Checklist:

  • Analyze all changed files and understand migration scope
  • Review test structure and patterns
  • Check schema changes in testtools
  • Examine turbo.json configuration changes
  • Provide comprehensive feedback and recommendations

✅ Positive Aspects

1. Well-Structured Test Organization

  • Clean separation with v2-migrated/ directory structure
  • Consistent naming pattern (issue-{number}.test.ts)
  • Good use of existing test utilities from @zenstackhq/testtools

2. Comprehensive Issue Coverage

  • Covers diverse scenarios: schema validation, policy testing, relations, enums, datatypes
  • Tests address real-world bugs from GitHub issues 177, 389, 392, 416, 509, 609, 632, 646

3. Proper Test Infrastructure

  • Enhanced testtools with new loadSchema() and loadSchemaWithError() utilities
  • Consistent use of appropriate test clients (createPolicyTestClient, createTestClient, loadDocument)

🔧 Infrastructure Improvements

1. testtools/schema.ts Additions

// Good additions for schema testing
export async function loadSchema(schema: string) // lines 93-107
export async function loadSchemaWithError(schema: string, error: string | RegExp) // lines 109-132
  • ✅ Proper error handling with detailed messages
  • ✅ Support for both string and RegExp error matching
  • ✅ Automatic datasource injection when missing
  • ✅ Temp file cleanup approach

2. turbo.json Fix

"watch": {
-   "dependsOn": ["^build"],
+   "dependsOn": ["^watch"],
  • ✅ Corrects watch dependency to avoid build bottlenecks

🐛 Potential Issues & Recommendations

1. Security: Temp File Management (testtools/schema.ts:99, 116)

const tempFile = path.join(os.tmpdir(), `zenstack-schema-${crypto.randomUUID()}.zmodel`);

Issue: Temp files are created but never explicitly cleaned up
Recommendation: Add cleanup in finally blocks or use fs.rmSync() after operations

2. Test Quality: Missing Edge Cases

  • issue-392.test.ts: Tests one-to-one relations but doesn't verify the actual relationship behavior
  • issue-646.test.ts: Only tests schema loading, not decimal precision handling

3. Performance: Test Database Strategy

  • Some tests use usePrismaPush: true (issue-609, issue-632) while others don't
  • Recommendation: Document when to use each approach for consistency

4. Code Quality: Type Safety

// testtools/schema.ts:102-104
expect(r).toSatisfy(
    (r) => r.success,
    `Failed to load schema: ${(r as any).errors?.map((e: any) => e.toString()).join(', ')}`,
);

Issue: Using any types loses type safety
Recommendation: Define proper error types or use type guards

📊 Test Coverage Assessment

Excellent Coverage For:

  • Schema validation errors (issue-177)
  • Policy enforcement (issue-389, issue-609)
  • Relation configurations (issue-392)
  • String escaping in defaults (issue-416)
  • Omit decorator with policies (issue-509)
  • Enum handling (issue-632)
  • Decimal precision (issue-646)

Missing Coverage:

  • Integration tests with actual CRUD operations for most issues
  • Performance regression verification
  • Cross-database provider compatibility (most tests use default provider)

🚀 Performance Considerations

  • Tests are lightweight and focused - good for CI/CD
  • Database creation strategy is efficient with name hashing
  • Turbo.json fix should improve watch mode performance

🔒 Security Assessment

  • No security vulnerabilities in test code
  • Schemas use appropriate validation patterns
  • No hardcoded secrets or sensitive data

📝 Final Recommendation

✅ APPROVE - This is a high-quality migration that:

  • Maintains test integrity while adapting to v3 architecture
  • Adds valuable testing utilities to the testtools package
  • Fixes a real build system issue in turbo.json
  • Follows established patterns and conventions

Minor improvements suggested:

  1. Add temp file cleanup in schema.ts
  2. Consider more comprehensive integration tests for complex issues
  3. Improve type safety in error handling

The migration successfully preserves the intent of the original regression tests while leveraging v3's improved testing infrastructure.

Walkthrough

Introduces two test utility exports for schema loading and error assertion, and adds multiple regression tests covering schema parsing/validation, relations, policies, quoted defaults, decimals, and enum defaults. Imports updated for temp file handling and assertions. No changes to core runtime logic beyond new test helpers.

Changes

Cohort / File(s) Summary
Testtools: schema helpers
packages/testtools/src/schema.ts
Adds loadSchema and loadSchemaWithError utilities. Generates temp files via os.tmpdir and crypto.randomUUID, prefixes schema with sqlite datasource if missing, parses with loadDocument, and asserts success/failure using vitest and invariant.
Regression tests: schema load/parse/validate
tests/regression/test/v2-migrated/issue-177.test.ts, tests/regression/test/v2-migrated/issue-392.test.ts, tests/regression/test/v2-migrated/issue-416.test.ts, tests/regression/test/v2-migrated/issue-509.test.ts, tests/regression/test/v2-migrated/issue-646.test.ts
Adds tests asserting parser/validator behavior for relation optionality errors, varied model/relational schemas, quoted string and JSON defaults (PostgreSQL), complex models with access directives, and Decimal default values. Uses loadSchema/loadDocument.
Regression tests: policy/test client scenarios
tests/regression/test/v2-migrated/issue-389.test.ts, tests/regression/test/v2-migrated/issue-609.test.ts, tests/regression/test/v2-migrated/issue-632.test.ts
Adds policy-driven tests: create constraints (value > 0), nested comment connect under authorization, and enum defaults with Prisma push using test client.

Poem

I thump my paws on tidy ground,
New schemas hop, with errors found.
Temp-file burrows, UUID trails,
Policies guard the carrot pails.
Decimals, enums—defaults sing,
Quoted strings do everything.
All tests pass—my whiskers spring! 🐇✨

  • These two functions duplicate logic for prelude injection and temp file creation; extracting a shared helper (e.g., prepareSchemaTempFile) would reduce duplication and ease future changes (like adding cleanup). Refactor to a common internal utility returning the temp file path.

93-108: Consider cleaning up temporary files.

The function creates temporary files in os.tmpdir() but never removes them. Over time, this could accumulate test artifacts.

Consider adding cleanup:

 export async function loadSchema(schema: string) {
     if (!schema.includes('datasource ')) {
         schema = `${makePrelude('sqlite')}\n\n${schema}`;
     }
 
     // create a temp file

-    expect(r).toSatisfy(

-        `Failed to load schema: ${(r as any).errors?.map((e: any) => e.toString()).join(', ')}`,

-    invariant(r.success);
-    return r.model;
+        expect(r).toSatisfy(

+        invariant(r.success);
+        return r.model;

4-20: Consider adding a brief comment describing issue 416.

While the test correctly verifies that the schema loads successfully with escaped quotes in default values, a one-line comment describing the original issue would improve maintainability and help future readers understand what bug this test prevents.

10-10: LGTM! Logical dependency change for watch tasks.

The change from ["^build"] to ["^watch"] makes sense for development workflows, allowing watch tasks to depend on upstream watch tasks for continuous rebuilding.

tests/regression/test/v2-migrated/issue-509.test.ts (1)

4-29: Verify test intent: no assertion on schema load result.

The test calls loadDocument but doesn't assert or check the result. loadDocument returns a result object with { success: true/false, ... } rather than throwing on failure, so the test will pass even if schema loading fails.

Consider using the loadSchema helper from @zenstackhq/testtools (introduced in this PR) which automatically asserts success:

-import { loadDocument } from '@zenstackhq/language';
+import { loadSchema } from '@zenstackhq/testtools';
 import { it } from 'vitest';
 
 it('verifies issue 509', async () => {
-    await loadDocument(
+    await loadSchema(
         `
             model User {
                 id Int @id @default(autoincrement())
                 email String @unique
                 name String?
                 posts Post[]
             }
               
             model Post {
                 id Int @id @default(autoincrement())
                 title String
                 content String?
                 published Boolean @default(false)
                 author User? @relation(fields: [authorId], references: [id])
                 authorId Int?
               
                 deleted Boolean @default(false) @omit
               
                 @@allow('all', true)
                 @@deny('read', deleted)
             }
             `,
     );
 });

Alternatively, if the intent is to verify the schema loads successfully without assertion, please add a comment explaining this.

tests/regression/test/v2-migrated/issue-609.test.ts (1)

4-59: LGTM! Well-structured policy enforcement test.

The test clearly verifies cross-user comment relationships under policy constraints. The setup, seeding, and assertions are well-organized.

tests/regression/test/v2-migrated/issue-392.test.ts (1)

4-63: Verify test intent: no assertions on schema load results.

The test calls loadDocument four times but never checks the results. Since loadDocument returns a result object rather than throwing on failure, the test will pass even if schema loading fails.

Consider using the loadSchema helper from @zenstackhq/testtools which automatically asserts success:

-import { loadDocument } from '@zenstackhq/language';
+import { loadSchema } from '@zenstackhq/testtools';
 import { it } from 'vitest';

4-15: LGTM! Clear policy constraint test.

The test effectively validates field-level policy enforcement with the value > 0 constraint, asserting both rejection and success cases.

tests/regression/test/v2-migrated/issue-646.test.ts (1)

4-11: LGTM! Test verifies Decimal default value support.

The test uses loadSchema which internally asserts successful schema loading, so it effectively verifies that the Decimal type with a small default value (0.00000001) parses correctly.

tests/regression/test/v2-migrated/issue-177.test.ts (1)

4-25: LGTM! Effective relation constraint validation test.

The test properly uses loadSchemaWithError to verify that the schema parser correctly detects and reports the mismatch between non-optional relation bar and optional field barId1.

tests/regression/test/v2-migrated/issue-416.test.ts (1)

1-2: LGTM!

The imports are correct and align with the test structure.

tests/regression/test/v2-migrated/issue-632.test.ts (1)

1-2: LGTM!

The imports are correct and align with the test structure.

PR Review: Migrating V2 Regression Cases

I've completed a thorough review of this PR that migrates 7 regression test cases from v2 to v3. Overall, this is a solid migration with good test structure and necessary infrastructure improvements.

Review Checklist:

  • Analyze all changed files and understand migration scope
  • Review test structure and patterns
  • Check schema changes in testtools
  • Examine turbo.json configuration changes
  • Provide comprehensive feedback and recommendations

✅ Positive Aspects

1. Well-Structured Test Organization

  • Clean separation with v2-migrated/ directory structure
  • Consistent naming pattern (issue-{number}.test.ts)
  • Good use of existing test utilities from @zenstackhq/testtools

2. Comprehensive Issue Coverage

  • Covers diverse scenarios: schema validation, policy testing, relations, enums, datatypes
  • Tests address real-world bugs from GitHub issues 177, 389, 392, 416, 509, 609, 632, 646

3. Proper Test Infrastructure

  • Enhanced testtools with new loadSchema() and loadSchemaWithError() utilities
  • Consistent use of appropriate test clients (createPolicyTestClient, createTestClient, loadDocument)

🔧 Infrastructure Improvements

1. testtools/schema.ts Additions

// Good additions for schema testing
export async function loadSchema(schema: string) // lines 94-109
export async function loadSchemaWithError(schema: string, error: string | RegExp) // lines 111-133
  • ✅ Proper error handling with detailed messages
  • ✅ Support for both string and RegExp error matching
  • ✅ Automatic datasource injection when missing

2. turbo.json Fix

"watch": {
-   "dependsOn": ["^build"],
+   "dependsOn": ["^watch"],
  • ⚠️ POTENTIAL ISSUE: This change may cause watch tasks to wait on upstream watch tasks that are long-running/non-terminating, potentially preventing this task from starting

🐛 Potential Issues & Recommendations

1. Security: Temp File Management (testtools/schema.ts:100, 117)

const tempFile = path.join(os.tmpdir(), `zenstack-schema-${crypto.randomUUID()}.zmodel`);

Issue: Temp files are created but never explicitly cleaned up
Recommendation: Add cleanup in finally blocks or use fs.rmSync() after operations

2. Test Quality: Missing Edge Cases

  • issue-392.test.ts: Tests one-to-one relations but doesn't verify the actual relationship behavior
  • issue-646.test.ts: Only tests schema loading, not decimal precision handling

3. Performance: Test Database Strategy

  • Some tests use usePrismaPush: true (issue-609, issue-632) while others don't
  • Recommendation: Document when to use each approach for consistency

4. Code Quality: Type Safety

// testtools/schema.ts:105
expect(r).toSatisfy(
    (r) => r.success,
    `Failed to load schema: ${(r as any).errors?.map((e: any) => e.toString()).join(', ')}`,
);

Issue: Using any types loses type safety
Recommendation: Define proper error types or use type guards

📊 Test Coverage Assessment

Excellent Coverage For:

  • Schema validation errors (issue-177)
  • Policy enforcement (issue-389, issue-609)
  • Relation configurations (issue-392)
  • String escaping in defaults (issue-416)
  • Omit decorator with policies (issue-509)
  • Enum handling (issue-632)
  • Decimal precision (issue-646)

Missing Coverage:

  • Integration tests with actual CRUD operations for most issues
  • Performance regression verification
  • Cross-database provider compatibility (most tests use default provider)

🚀 Performance Considerations

  • Tests are lightweight and focused - good for CI/CD
  • Database creation strategy is efficient with name hashing
  • Turbo.json change needs review (see concerns above)

🔒 Security Assessment

  • No security vulnerabilities in test code
  • Schemas use appropriate validation patterns
  • No hardcoded secrets or sensitive data

📝 Final Recommendation

✅ APPROVE - This is a high-quality migration that:

  • Maintains test integrity while adapting to v3 architecture
  • Adds valuable testing utilities to the testtools package
  • Follows established patterns and conventions

Minor improvements suggested:

  1. Add temp file cleanup in schema.ts
  2. Consider reverting turbo.json change or documenting the rationale
  3. Consider more comprehensive integration tests for complex issues
  4. Improve type safety in error handling

The migration successfully preserves the intent of the original regression tests while leveraging v3's improved testing infrastructure.

129-129: Make string coercion explicit for clarity.

Using error.test(e) relies on implicit object-to-string coercion. Making it explicit improves clarity and avoids surprises if error object shapes change.

Apply this diff:

-            (r) => r.errors.some((e: any) => error.test(e)),
+            (r) => r.errors.some((e: any) => error.test(e.toString())),

100-108: Temp files accumulate without cleanup.

Temporary files created via crypto.randomUUID() are never deleted, which can accumulate during large test runs.

Wrap the load/assert in try/finally and call fs.unlinkSync(tempFile) in the finally block:

     // create a temp file
     const tempFile = path.join(os.tmpdir(), `zenstack-schema-${crypto.randomUUID()}.zmodel`);
     fs.writeFileSync(tempFile, schema);
-    const r = await loadDocument(tempFile);
-    expect(r).toSatisfy(
-        (r) => r.success,
-        `Failed to load schema: ${(r as any).errors?.map((e: any) => e.toString()).join(', ')}`,
-    );
-    invariant(r.success);
-    return r.model;
+    try {
+        const r = await loadDocument(tempFile);
+        expect(r).toSatisfy(
+            (r) => r.success,
+            `Failed to load schema: ${(r as any).errors?.map((e: any) => e.toString()).join(', ')}`,
+        );
+        invariant(r.success);
+        return r.model;
+    } finally {
+        try {
+            fs.unlinkSync(tempFile);
+        } catch {
+            // ignore cleanup errors
+        }
+    }

117-121: Temp files accumulate without cleanup.

Temporary files created via crypto.randomUUID() are never deleted, which can accumulate during large test runs.

Wrap the load/assert in try/finally and call fs.unlinkSync(tempFile) in the finally block:

     // create a temp file
     const tempFile = path.join(os.tmpdir(), `zenstack-schema-${crypto.randomUUID()}.zmodel`);
     fs.writeFileSync(tempFile, schema);
-    const r = await loadDocument(tempFile);
-    expect(r.success).toBe(false);
-    invariant(!r.success);
-    if (typeof error === 'string') {
+    try {
+        const r = await loadDocument(tempFile);
+        expect(r.success).toBe(false);
+        invariant(!r.success);
+        if (typeof error === 'string') {
+            expect(r).toSatisfy(
+                (r) => r.errors.some((e: any) => e.toString().toLowerCase().includes(error.toLowerCase())),
+                `Expected error message to include "${error}" but got: ${r.errors.map((e: any) => e.toString()).join(', ')}`,
+            );
+        } else {
+            expect(r).toSatisfy(
+                (r) => r.errors.some((e: any) => error.test(e.toString())),
+                `Expected error message to match "${error}" but got: ${r.errors.map((e: any) => e.toString()).join(', ')}`,
+            );
+        }
+    } finally {
+        try {
+            fs.unlinkSync(tempFile);
+        } catch {
+            // ignore cleanup errors
+        }
+    }
+```

Note: The diff also includes the fix for line 129 (explicit `.toString()` call).

`94-109`: **Code duplication: consolidate with language/test/utils.ts.**

This function is nearly identical to `loadSchema` in `packages/language/test/utils.ts` (lines 7-18). Consider consolidating by either:
1. Having `language/test/utils.ts` import and re-export this function, or
2. Moving the shared implementation to a common location

This reduces maintenance burden and ensures consistent behavior across test utilities.
