Run a collection of tests
Run transformations on all *-in.R files in a test directory and compare them with their *-out.R counterpart.
test_collection( test, sub_test = NULL, dry = "off", write_tree = NA, transformer, ... )
test |
The test to run. It corresponds to a folder name in tests/testthat. |
sub_test |
A regex pattern to further reduce the amount of test files
to be tested in the test. |
dry |
To indicate whether styler should run in dry mode, i.e. refrain
from writing back to files . |
write_tree |
Whether or not the tree structure of the test should be
computed and written to a file. Note that this needs R >= 3.2
(see |
transformer |
A function to apply to the content of |
... |
Parameters passed to transformer function. |
Each file name that matches test and sub_test and ends with
"-in.R" is considered as an input to test. Its counterpart,
the reference to compare it against is the *-out.R file. It is constructed
by taking the substring of the *-in.R file before the
last dash and adding -out.R. In contrast to older versions of this
function, every *-out.R file has just one in file.
