RStudio IDE "Run Tests" with failed expectation generates IDE error

[trestletech]

In the RStudio IDE:

• Start with a Shiny app that has no tests/ dir
• Record a shinytest via shinytests::recordTest()
• It will bring up the test script at the end. Go into the expected directory and change some value so that the expectations are now wrong (or change the app source)
• click "Run Tests" in the script that was opened.

Observe this error.

I think this is where the IDE is going wrong. Appending tests/ to the app path and looking in there. As noted in #293, the IDE is already pointing to the wrong appdir path; now appending another invalid path to that one.

From the IDE diagnostics, we're getting that butchered path which didn't go up far enough (i.e. the appdir is ___/tests/) and now we're assuming that the terminal dir is inevitably called tests which gets appended. Thus we're looking for app/tests/tests/mytest.R which, of course, doesn't exist.

Jonathan pointed out that we could add a check into the shinytest package that checks the version of the IDE and presents a warning if it thinks there are going to be issues.

Given the overall development resources available to shinytest and the fact that this will naturally resolve itself as people upgrade the ide, I think it's best just to close this issue.
