 Testing is a critical part of the development process. In this section, you'll learn how to:
 
-- Run unit tests using Vitest inside a Docker container.
-- Use Docker Compose to run tests in an isolated, reproducible environment.
+- Run Jasmine unit tests using the Angular CLI inside a Docker container.
+- Use Docker Compose to isolate your test environment.
+- Ensure consistency between local and container-based testing.
 
-You’ll use [Vitest](https://vitest.dev) — a blazing fast test runner designed for Vite — along with [Testing Library](https://testing-library.com/) for assertions.

-### Step 1: Install Vitest and React Testing Library

-If you haven’t already added the necessary testing tools, install them by running:
-
-```console
-$ npm install --save-dev vitest @testing-library/angular @testing-library/jest-dom jsdom
+$ src/app/app.component.spec.ts

+This test uses Jasmine to validate the AppComponent logic.
 
-```json

-  "test": "vitest run"
-}
-```

-
-### Step 2: Configure Vitest
-
-Update `vitest.config.ts` file in your project root with the following configuration:
-
-```ts {hl_lines="14-18",linenos=true}
-/// <reference types="vitest" />
-
-import { defineConfig } from "vite";
-import angular from "@vitejs/plugin-angular";

-export default defineConfig({

-  test: {
-    environment: "jsdom",
-    setupFiles: "./src/setupTests.ts",
-    globals: true,
-  },
-});
-```
-
-> [!NOTE]
-> The `test` options in `vitest.config.ts` are essential for reliable testing inside Docker:
-> - `environment: "jsdom"` simulates a browser-like environment for rendering and DOM interactions.  
-> - `setupFiles: "./src/setupTests.ts"` loads global configuration or mocks before each test file (optional but recommended).  
-> - `globals: true` enables global test functions like `describe`, `it`, and `expect` without importing them.
->
-> For more details, see the official [Vitest configuration docs](https://vitest.dev/config/).

+In this section, you learned how to run unit tests for your Angular application inside a Docker container using Jasmine and Docker Compose.
 
 What you accomplished:
-- Installed and configured Vitest and React Testing Library for testing React components.
 - Created a `angular-test` service in `compose.yaml` to isolate test execution.
 - Reused the development `Dockerfile.dev` to ensure consistency between dev and test environments.
 - Ran tests inside the container using `docker compose run --rm angular-test`.
