I have a function below (just an example). What's the
recommended way to unit-test it for all `version` cases?
```d
void f()
{
import std.stdio: writeln;
version(foo)
writeln("foo");
else
writeln("no foo");
}
```
Probably the easiest way is to split it into two functions
```d
void f()
{
version (foo)
fVersionFoo();
else
fDefault();
}
void fVersionFoo()
{
/* ... */
}
void fDefault()
{
/* ... */
}
```
Then you can write separate unit tests for both `fVersionFoo` and
`fDefault`, and they will both be tested regardless of what
settings you build with.
