snapshot_review() says "no snapshots to update" when there are files that have changed

[njtierney]

Hello!

I'm not really sure how to distill this down to a reprex, but when I have an existing change in my snapshot testing, like so:

when I run

snapshot_review('tensorflow-rpkg-stability')
# or
snapshot_review()

I get

No snapshots to update

I would expect that given my snapshots have changed, I should see the really nice diff window from snapshot_review(), but I do not.

Below is my sessionInfo, if that helps

This problem appears when the test file has a dot in its name, like test-hello.foo.R. However, I can't reproduce it with dashes in the name like in the original issue. I put a small reprex on this repo: snapshotreprex.

To reproduce:

• change the message in R/hello.R
• run the tests. This correctly detects the change in the output

• run testthat::snapshot_review('windows/hello.foo') (or click it)
• output: "No snapshots to update"

In tests/testthat/_snaps/windows, there are hello.foo.md and hello.foo.new.md.

---

Edit: running testthat::snapshot_review('windows/hello.foo.md') works, so maybe it just requires a small update to testthat message
