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, write_back = TRUE, 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. |
write_back | Whether the results of the transformation should be written to the output file. |
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.
