Vue.js is a popular JavaScript framework, and as such, it is crucial to ensure that its components work as they are supposed to: effectively, and more importantly, reliably. Mocking dependencies is one of the most efficient methods of testing, as we will discover in this article.
The Need for Mocking Dependencies
Mocking dependencies is a way of exerting control over tests by providing the capacity to isolate components under test from their dependencies. As all frameworks work with multiple components, which can range from APIs to services and even interactions such as clicks or hovers, it is important to be able to isolate these components to test for their durability, behavior, and reliability. Mocking dependencies allow users to create a controlled testing environment to verify the component's behavior in isolation.
