An example of an AI chatbot conversation about Jest snapshots and their commands.
What are Jest snapshots and how do I use them?
Jest snapshots are a feature in Jest that allows you to test the output of your components. You can create a snapshot by rendering a component and saving its output to a file.
How do I create a snapshot in Jest?
To create a snapshot, you can use the toMatchSnapshot() method in your test. For example, expect(component).toMatchSnapshot(); will generate a snapshot file.
What happens if the output changes?
If the output changes, Jest will alert you that the snapshot has failed. You can then choose to update the snapshot if the changes are intentional.
Can I view the snapshot files?
Yes, the snapshot files are stored in a __snapshots__ directory next to your test files. You can open them to see the saved output.
