How do I troubleshoot snapshot tests in my application?
To troubleshoot snapshot tests, start by checking the error messages for clues. What specific issues are you encountering?
I'm getting a mismatch error when I run the tests.
A mismatch error usually means the output has changed. Have you updated any components or libraries recently?
Yes, I updated a UI component. Should I update the snapshots?
Yes, if the changes are intentional, you can update the snapshots using the command jest --updateSnapshot
. Make sure to review the changes!
What if the changes are not intentional?
If the changes are not intentional, you should investigate the component's code to identify any unintended modifications.
