Test only fails in Windows job on Github Actions

[FrieseWoudloper]

I created a very basic Shiny app and accompanying test using shinytest. The test passes on my Windows laptop. After I push my local repo to Github, the tests passes for the macOS and ubuntu jobs in Github Actions, but fails for the Windows job. See https://github.com/FrieseWoudloper/reprexshinytest/actions/runs/398213952

When I look at the log file, it seems to me there is a problem with line breaks:

< {

<   "input": {

< 

<   },

<   "output": {

< 

<   },

<   "export": {

< 

<   }

< }

---
> {
>   "input": {
> 
>   },
>   "output": {
> 
>   },
>   "export": {
> 
>   }
> }

Am I correct? How do I solve this issue?

I am having identical issues. My log output looks like:

-- FAILURE (test-app.R:9:3): all modules work ----------------------------------
Not all shinytest scripts passed for apps/selector_app: selector_test

It might be related to how git on Windows converts \n to \r\n when you do a checkout. You could try doing something like this:

https://github.com/rstudio/shinycoreci-apps/blob/6f2cc1e6bc59e509b8b151190d9dd50ec9efaadd/.github/workflows/ci-runtests.yml#L161-L164

So to clarify, that step needs to be present before any actions/checkout step. This fixed the issue for me.

It also fixed my problem. Thanks!
