Here's the problem I have:

I am using my custom Logger in Nest.js:

export class ReportLogger extends ConsoleLogger {
  verbose(message: string) {
    console.log('【Verbose】Reporting', message);
    super.verbose.apply(this, arguments);
  }

  log(message: string) {
    console.log('【Log】Reporting', message);
    super.log.apply(this, arguments);
  }
}

And the log.interceptor.ts file:

export class LogInterceptor implements NestInterceptor {
  constructor(private reportLogger: ReportLogger) {
    this.reportLogger.setContext('LogInterceptor');
  }

  intercept(context: ExecutionContext, next: CallHandler) {
    const http = context.switchToHttp();
    const request = http.getRequest();

    const now = Date.now();
    return next
      .handle()
      .pipe(
        tap(() =>
          this.reportLogger.log(
            `${request.method} ${request.url} ${Date.now() - now}ms`,
          ),
        ),
      );
  }
}

And here's the main.ts file:

async function bootstrap() {
  const reportLogger = new ReportLogger();

  const app = await NestFactory.create<NestExpressApplication>(AppModule, {
    cors: {
      origin: ['http://localhost', 'http://localhost:3000'],
      credentials: true,
    },
    bufferLogs: true,
    logger: reportLogger,
  });

  app.useGlobalInterceptors(
    new LogInterceptor(reportLogger),
  );

  setupSwagger(app);

  await app.listen(4200);
}

When I run npm run start:dev to run the Nest App on dev, everything works fine. But when I run npm run test:e2e or npm run test on testing, it shows this error:

  Using the "extends Logger" instruction is not allowed in Nest v8. Please, use "extends ConsoleLogger" instead.

      10 |     const moduleFixture: TestingModule = await Test.createTestingModule({
      11 |       imports: [AppModule],
    > 12 |     }).compile();
         |        ^
      13 |
      14 |     app = moduleFixture.createNestApplication();
      15 |     await app.init();

I read the Nest.js doc again, and found the Logging breaking change in the docs. But the question is I have already made my ReportLogger extends ConsoleLogger, why this error shows again? And why it only shows in testing?
