Enzyme: When to use shallow, render, or mount?

问题:

From the Enzyme docs shallow, render, and mount are described, but when to use which method?

回答1:

shallow

• No children rendering
• Isolated, you know for sure the error comes from here

render

• No lifecycles
• Render children
• Less APIs (setState, debug...)

mount

Will require jsdom or similar.

• Lifecycle methods, like componentDidMount
• Render children

---

If some of your children are connected components, you probably don't want to use mount, or you will need to setup a <Provider> and store creation, which would be a bit painful, just use shallow in this case.

This post is really insightful about the subject.
