Hi Tup users,
I am trying to write a Tupfile for facilitating TDD on a C/C++ based
project.
My Tupfile builds the unit test executables correctly. However, I am now
attempting to modify the Tupfile to run just the changed unit test
executables. One way to achieve this is to redirect all execution output of
unit tests to a results file using a Tup rule like so -
: foreach {TEST_EXES} |> %f >%o 2>&1 |> %f.results {TEST_RESULTS}
And then echo the results to stdout if any of the results files are
newer than the executables.
: foreach {TEST_RESULTS} |> echo %f |>
However, the first Tup rule above throws an error like so -
[ tup ] [0.105s] Executing Commands...
* 5% 1) tests/obj/unittest.exe >tests/obj/unittest.exe.results 2>&1
*** tup errors ***
*** Command ID=9688 failed with return value 1
Am I going down the wrong path and using Tup in a way that was not intended
here? I'd appreciate any alternate suggestions/ideas to achieve the end
result. All I am after is for the compile, link and execute cycle to be
lightning fast to facilitate Test Driven Development.
Thanks!
