Hi,
I 'm converting a project to CMake. Tests in this project print messages
to cout and these output traces are compared to reference files. If
output and its reference are different, the corresponding test is
considered as failed. I can't see how to make these tests work with CMake.
I try to run a complex command in ADD_TEST like
ADD_TEST (Test test --arg_test > output && ${DIFF_COMMAND} output
reference_file).
DIFF_COMMAND is equal to diff under Unix and fc under Windows. But CMake
interprets test commands and '>' is passed as an argument to test
("test" "--arg_test" ">" "output" "&&" "diff" "output" "reference_file").
I try to set property PASS_REGULAR_EXPRESSION to contents of reference
file. It works for little files but it's difficult for large files :
- All characters * . ( ) ^ $ ... must be backslashed.
- In this project, generated files are encoded in UTF-8 and I'm not
sure that CMake regular expressions support UTF-8.
- When there is a difference, I can't see where it is. I understand
that PASS_REGULAR_EXPRESSION wasn't thought in terms of matching whole file.
I could modify source of program tests by redirecting std::cout to a
file and comparing this file to the reference file. But before doing
this, I would like to know if there is a way to make a test with command
like `test args > file && diff` or if it's possible to add a test
property which compare output of the program to a no regular expression.
You can do something like this:
ADD_TEST(MyTestCreate Test test --arg_test --output output)
ADD_TEST(MyTestCreateCompare ${CMAKE_COMMAND} -E compare_files output
outputTest)
