Code Review

The pull request introduces integration tests for the NestJS generator using Dagger. The infrastructure for building the CLI and running the test application in a containerized environment is well-structured. However, the test application currently only verifies the underlying Node.js flag evaluation logic and does not exercise the NestJS-specific features produced by the generator, such as the GeneratedOpenFeatureModule and the generated decorators. Additionally, some minor improvements to the Go test runner's portability and efficiency are recommended.

The integration test is currently using the base OpenFeatureModule from the SDK. To properly validate the NestJS generator, it should use the GeneratedOpenFeatureModule produced by the generator. This ensures that the generated module's provider logic and injection tokens are working correctly.

The test currently evaluates flags by manually retrieving the client and calling .value(). While this tests the Node.js generator's output, it does not test the NestJS-specific decorators (e.g., @EnableFeatureA()) which are the primary output of this generator. Consider adding a service or controller to the test app that uses these decorators to ensure they correctly inject flag values.

Running go mod tidy during an integration test build is generally unnecessary and can lead to unexpected changes in the go.mod file if the environment differs. go mod download is sufficient for ensuring dependencies are present for the build.

Using os.Getenv("PWD") is less portable as the PWD environment variable is not guaranteed to be set in all environments (e.g., on Windows or in certain CI runners). os.Getwd() is the standard, cross-platform way to retrieve the current working directory in Go.

Suggested change

Code Review

The addition of integration tests for the NestJS generator is a valuable improvement to ensure the reliability of the generated code. The use of Dagger provides a consistent and reproducible testing environment. The feedback provided focuses on improving the robustness of the test runner and ensuring that the integration test effectively covers the NestJS-specific features (decorators) that this generator provides.

The import path ./generated is ambiguous and will likely cause a TypeScript compilation error. The generator produces multiple files in that directory (e.g., openfeature.ts and openfeature-decorators.ts) but does not create an index.ts to serve as an entry point. You should import specifically from the file containing the classes you are testing. Additionally, since this is a NestJS-specific integration test, it should ideally verify the functionality of the generated decorators (e.g., @EnableFeatureA()) which are the primary value-add of this generator over the standard NodeJS one.

import * as generated from './generated';

Using os.Getenv("PWD") is generally discouraged for retrieving the current working directory because the PWD environment variable is set by the shell and may not be present or accurate in all execution contexts (e.g., when the binary is invoked directly or in certain CI environments). It is more robust to use os.Getwd().

Using the hardcoded string 'OPENFEATURE_CLIENT' for the injection token is brittle. It is recommended to use the OPENFEATURE_CLIENT constant exported by the @openfeature/nestjs-sdk package to ensure consistency and maintainability.

Thanks for the review! Working on addressing all the feedback now.

- Use os.Getwd() instead of os.Getenv("PWD") for better portability
- Remove go mod tidy from integration test build (unnecessary)
- Fix import path to './generated/openfeature' for clarity
- Use OPENFEATURE_CLIENT constant instead of hardcoded string
- Use GeneratedOpenFeatureModule to properly test the generator
- Add TestService with NestJS decorators to validate primary generator output
- Verify decorators inject flag values correctly

Code Review

This pull request adds Dagger-based integration tests for the NestJS code generator. The changes include a new Makefile target, the Dagger test runner in Go, and a NestJS test application. The implementation is solid and covers the necessary test cases. I've made a couple of suggestions to improve maintainability and code quality. One suggestion is to refactor the duplicated test execution logic in the main test runner. Another is to enable stricter TypeScript compiler options in the test project for better type safety.

This block of code is very similar to the blocks for running other integration tests in this file (C#, Go, NodeJS, Angular). This duplication makes the file harder to maintain. To improve maintainability, consider refactoring this logic into a helper function to avoid repetition. A single function could handle command creation, execution, output streaming, and error handling for all tests.

For better code quality and to catch potential bugs early, it's recommended to enable stricter type-checking options. strictNullChecks helps prevent errors from null and undefined values, and noImplicitAny ensures all variables have explicit types.

Code Review

This pull request successfully adds Dagger-based integration tests for the NestJS code generator, which is a great addition for ensuring the quality of the generated code. My review includes a few suggestions to improve the maintainability and type-safety of the new test files. Specifically, I've pointed out opportunities to refactor duplicated code in the test runner, improve type strictness in the TypeScript configuration and test application, and enhance the structure of the main test function for better readability.

This block adds to the existing code duplication in this file for running integration tests. To improve maintainability and reduce boilerplate, consider refactoring this logic into a helper function or a loop.

For example, you could define a helper function:

func runTest(name, path string) {
    fmt.Printf("--- Running %s integration test ---\n", name)
    cmd := exec.Command("go", "run", path)
    cmd.Stdout = os.Stdout
    cmd.Stderr = os.Stderr
    if err := cmd.Run(); err != nil {
        fmt.Fprintf(os.Stderr, "Error running %s integration test: %v\n", name, err)
        os.Exit(1)
    }
}

Then, the main function could be simplified to a series of calls to this helper, or a loop over a slice of tests. This would make adding new tests much cleaner.

@generated.DiscountPercentage() private discountPercentage: number,
@generated.GreetingMessage() private greetingMessage: string,
@generated.UsernameMaxLength() private usernameMaxLength: number,
@generated.ThemeCustomization() private themeCustomization: any,

For better type safety, avoid using any. You can define a specific interface for the themeCustomization object, which will provide better autocompletion and prevent potential runtime errors.

For example, you could define an interface at the top of the file:

interface Theme {
  primaryColor: string;
  secondaryColor: string;
}

And then use it in the constructor:

@generated.ThemeCustomization() private themeCustomization: Theme,

Alternatively, an inline type can be used as suggested.

Suggested change
@generated.ThemeCustomization() private themeCustomization: any,
@generated.ThemeCustomization() private themeCustomization: { primaryColor: string; secondaryColor: string },

The bootstrap function is quite long and handles multiple testing concerns. To improve readability and maintainability, consider breaking it down into smaller, more focused functions. For example, you could have separate functions for testing decorators, direct flag evaluation, and getKey() methods.

async function testDecorators(testService: TestService) {
  // ... logic for testing decorators
}

async function testDirectEvaluation(client: Client) {
  // ... logic for testing direct evaluation
}

function testGetKeyMethods() {
  // ... logic for testing getKey()
}

async function bootstrap() {
  const app = await NestFactory.createApplicationContext(AppModule);

  try {
    const client = app.get<Client>(OPENFEATURE_CLIENT);
    const testService = app.get(TestService);

    testDecorators(testService);
    await testDirectEvaluation(client);
    testGetKeyMethods();

    console.log('\n✅ Generated NestJS code compiles successfully!');
    console.log('✅ NestJS decorators work correctly!');
    console.log('✅ GeneratedOpenFeatureModule integrates properly!');

    await app.close();
    process.exit(0);
  } catch (error) {
    console.error('Error:', error);
    await app.close();
    process.exit(1);
  }
}

This structure makes the test flow clearer and each part easier to understand and modify.

The import path for GeneratedOpenFeatureModule is incorrect. The NestJS generator creates a file named 'openfeature-decorators.ts' which exports GeneratedOpenFeatureModule, but this import is trying to load it from 'openfeature-module'. This should be changed to './generated/openfeature-decorators' to match the actual generated file name.

Suggested change
import { GeneratedOpenFeatureModule } from './generated/openfeature-module';
import { GeneratedOpenFeatureModule } from './generated/openfeature-decorators';

The method used to get the project directory is inconsistent with other integration tests. All other integration tests (angular, csharp, go, nodejs) use filepath.Abs(os.Getenv("PWD")) instead of os.Getwd(). This should be changed to maintain consistency across integration tests and ensure reliability in different execution environments.

Suggested change
projectDir, err := os.Getwd()
projectDir, err := filepath.Abs(os.Getenv("PWD"))

The Node.js version used here (node:20-alpine) is inconsistent with other Node.js-based integration tests. Both the Angular and NodeJS integration tests use node:22-alpine. For consistency and to ensure tests run with the same Node.js version, this should be updated to use node:22-alpine instead.

Suggested change
From("node:20-alpine").
From("node:22-alpine").
