带有多个源文件扩展名的 Ceedling

Question

I am trying to setup up unit tests for my existing embedded project. Unfortunatly the project has mixed extentions for the source files ".c" and ".C". Due to version control history I cannnot just rename all files to ".c"

I tried to edit the yaml file accordingly, but it seems it ceedling only support one or the other extension.

Normal

...
:extension:
  :executable: .out
  :source: .c
...

Not working way, but desired

...
:extension:
  :executable: .out
  :source: .c ; .C
...

LED.C is not compiled. So the linker fails.

Test 'test_LED.c'
-----------------
Generating runner for test_LED.c...
Compiling test_LED_runner.c...
Compiling test_LED.c...
Linking test_LED.out...

This is currently does not seem possible with Ceedling as of 0.29.1 due to the source extensions being only used as a single configuration string and not an array. I highly recommend opening a feature request for it.

In the mean time, there is at leas a partial workaround you can do by creating symlink for each file. This is annoying, but will allow you to utilize ceedling without renaming all the files. For example if the file you want to test was in src:

ln -s LED.C src/LED.c
