Honestly, jest of facebook has a bad document.

I want to use jest -t xxx to update my snapshots.

Here is my test, but no one works correctly.

1. jest -u -t='test.tsx'

2. jest -u -t 'test.tsx'

3. jest -u -t /test.tsx/

4. jest -u -t=/test.tsx/

I want to match and update snapshots test files which filename pattern like *.test.tsx.

How can I do that with jest testNamePattern?

First check jest --showConfig to see that you even have the option of --testNamePattern. I faced the same issue, and did not find this option in jest config.

So I changed my directory structure and used --testPathPattern option with regex. This works.

jest --testPathPattern='(tests)/spec/./snapshot-tests/.'
