How and where is Protractor used?

Cases when Protractor does not work

1. Unsupported frameworks: Protractor is primarily designed for Angular applications. While it can also be used with non-Angular applications, it may not work as effectively or have limited functionality in such cases. If you are using a different front-end framework or a custom JavaScript application, Protractor may not be the most suitable choice for automated testing.
2. Non-HTML user interfaces: Protractor is designed to interact with HTML elements on web pages. If your application has a non-HTML user interface, such as a desktop application or a mobile app, Protractor may not be able to identify and interact with the elements, making it ineffective for testing such interfaces.
3. Complex authentication mechanisms: If your application has complex authentication mechanisms that involve multiple steps, redirects, or pop-ups, Protractor may face challenges in handling such scenarios. Protractor relies on the WebDriverJS library for browser automation, and certain authentication mechanisms may not be fully supported by WebDriverJS, leading to issues in test execution.
4. Asynchronous operations: Protractor is designed to handle Angular’s built-in mechanisms for managing asynchronous operations, such as promises and the Angular event loop. If your application heavily relies on custom or third-party asynchronous operations that are not fully compatible with Angular, Protractor may encounter difficulties in synchronizing test actions and assertions properly.
5. Outdated dependencies: Protractor depends on various software components, including the Selenium WebDriver, browser drivers, and the Node.js runtime. If you have outdated versions of these dependencies, it can lead to compatibility issues and unexpected behavior while using Protractor. It is important to ensure that all the required dependencies are up to date to maximize Protractor’s effectiveness.
