Testing Angular Components by Properties with Playwright

The @playwright-labs/selectors-angular package is a powerful tool designed to enhance Playwright's testing capabilities specifically for Angular applications. It provides a robust way to query and interact with Angular components using their properties rather than relying on fragile CSS selectors, which can break easily when the underlying DOM structure changes.

Key Features

1. Angular-aware Selectors: The package allows you to write queries that target Angular components based on their properties such as @Input, @Output, and signals.
2. Component-based Testing: Tests written with this package focus on the component's contract rather than its implementation details, making them more resilient to changes in the DOM structure.
3. Self-documenting Tests: The queries are descriptive and reflect the actual components and their properties, making tests easier to understand and maintain.

Basic Usage

To use @playwright-labs/selectors-angular, you need to import it into your Playwright test files and utilize its functions to query Angular components.

Installation

First, install the package via npm:

sh
 
1npm install @playwright-labs/selectors-angular
