This short article covers what "mocking" means in web development, how developers achieve this, and how it helps them. We'll also cover some disadvantages of mocking.
The term "mock" comes from the verb "to mock," which means to imitate or copy something in a teasing or derisive manner.
Mocks, or mock objects, are often referred to as "fake" because they are not the real thing. In testing, a mock is a simulated version of a real object or service, such as a database or a network connection. It is called a mock because it is not the real thing, but it behaves similarly and can be used to test the code without relying on the actual object or service.
In the context of testing, mocking is a way of imitating the behavior of a real object or service in a controlled and predictable way so that the code can be tested without relying on the real thing. So when developers refer to mocks as "fake" data, they use the term to indicate that the data is not real but is being used as a stand-in for testing purposes.

Disadvantages of mocking
One disadvantage of mocking HTTP requests is that it can make your tests less realistic. Since you are not actually making a real network request, your tests may not accurately reflect how the code will behave in a production environment. This can make it more difficult to catch bugs or other issues that only arise when the code is running in a real-world production environment.
Another disadvantage is that mocking HTTP requests can complicate your tests. Since you are not actually making a real network request, you have to manually set up all of the data that the code would receive in a real request. This can take a significant amount of time and effort, and it can make your tests more difficult to read and maintain.
While mocking HTTP requests can be a helpful tool, it is essential to use it wisely and only when necessary. Sometimes, it may be better to make an actual network request and use techniques like stubbing or faking to control the response data. This can provide a more realistic and efficient testing environment.
However, sometimes, it is handy to use mocking across any environment, for example, to debug an issue in production. With our browser extension tweak you can achieve all of this without worrying about the implementation details and the maintainability burden they pose for you and your team. Furthermore, you can use the tool seamlessly for testing across any environment, from local development to production.
