Travis CI build fails "testthat unit tests failed"; same test passes local test/check

Failing build for Github repo ukbtools.

The test, in tests/testthat/test-dataset.R, accesses data from inst/extdata with system.file and passes the returned path to a package function:

path_to_example_data <- system.file("extdata", package = "ukbtools")
ukbtools::ukb_df_field("ukbxxxx", path = path_to_example_data)

ukbtools::ukb_df_field calls xml2::read_html.default(file.path(path, "ukbxxxx.html")) which generates an invalid path on Travis CI (trusty/ xenial).

‘/home/travis/build/kenhanscombe/ukbtools/ukbtools.Rcheck/ukbtools/extdata/ukbxxxx.html’ does not exist.

The same test passess locally, sessionInfo

Linux filesystems are case sensitive, the macOS filesystem is (by default) not. Your files are actually called ukbXXXX, with capital X’s.

Thank you @jimhester. Git no longer tracking these files! I can’t git add the files in inst/extdata/ (–force doesn’t work). Last commit 8 Jan 2019. I’ve renamed the one incorrectly labelled local file and touched other 2 to register change but no joy.

Fixed. I had to completely remove the directory, commit, then replace the directory, to be able to add and commit.
