Jest Description

Jest is designed to operate seamlessly without configuration on the majority of JavaScript projects. It allows for easy tracking of large objects through tests. Snapshots can be stored alongside tests or embedded directly within them. To enhance performance, tests are executed in isolated processes, enabling parallel execution. By maintaining a distinct global state for each test, Jest ensures reliable parallel execution. Additionally, Jest prioritizes previously failed tests and reorganizes runs based on the duration of test files to speed up the testing process. With its custom resolver, Jest simplifies the mocking of any external objects within your tests, facilitating a smoother testing experience. Overall, Jest's features foster efficiency and ease of use for developers working on JavaScript applications.
