 ## Description
-
-This repository demonstrates how to effectively set up and execute integration tests for a Node.js application without using mocks inside **node.app:**
-
+Typically, when it comes to setting up integration tests and working with external dependencies, an approach is used where components are simulated through mocks. This means that database responses or requests via `axios` are artificially replaced with pre-defined results directly in the code. However, this repository demonstrates an alternative approach, where the tests interact with real external services, allowing for more accurate and comprehensive end-to-end validation of the application's functionality.
 ```typescript
 const moduleRef: TestingModule = await Test.createTestingModule({
   controllers: [UserController],

-Instead of simulating components in code like mocking what database or axios returns, the approach focuses on testing real interactions between outside services, ensuring more accurate, end-to-end validation of your application’s behavior. If you think about how your app should interact with external client or provider api without mocks of axios **(example below)**:

-The schema can be more detailed, it depends on your needs. Mocking DB or publishing events to message brokers is easier and cause no problems. In general node.js code wasn't modified or changed (except environmental variables for api calls). Now your scenarios are tested and you can be confident about identical behavior on production.
+The schema can be more detailed based on your needs. Mocking the database or handling events in message brokers is simpler and typically hassle-free. The core Node.js code remains unchanged (apart from adjusting environment variables for API calls). Now your scenarios are thoroughly tested, giving you confidence that the behavior will be consistent in production.
 ## Key Features
 - **No Code Mocking: Focuses on testing real integrations, without relying on mocks or stubs in node.js.**
 - **Production-like Testing: Verifies how the app interacts with external services in a more realistic, production-like environment.**
