jest updateSnapshot for specific test file

Question

I'm trying to figure out how o update a single snapshot file. In the docs it says just add the -t and I presume the file name but thats not working for me.

Example, in terminal I use.

jest -u -t test/js/tests/components/myTestApp.test.js

Any ideas why this would not work. I also added it as a string.

In order to update particular snapshot, you can pass name as an argument to your script test command.

In package.json

"test": "jest --verbose"

In command line

npm test "<spec name>" -- -u

OR

npm test "<spec name>" -- --updateSnapshot
