December 26, 2013 Unit testing D module | ||||
---|---|---|---|---|
| ||||
If i do not want to unit test whole codebase, because it big enough and all tests take noticeable time to run. So i trying this: dmd -unittest mymodule.d And getting error: "undefined reference to `main'" But i don't want to run 'main' here, just unit test please. Any idea how to test single module without putting 'main' in every module ? |

Use the `-main` compiler switch:
"Add a default main() function when compiling. This is useful
when unittesting a library, as it enables the user to run the
unittests in a library without having to manually define an
entry-point function."
So, dmd -unittest -main mymodule.d
