Note the implementation:
void assertNotThrown(T : Throwable = Exception, E)
(lazy E expression,
string msg = null,
string file = __FILE__,
size_t line = __LINE__)
{
try
expression();
catch(T t)
{
immutable tail = msg.empty ? "." : ": " ~ msg;
throw new AssertError(format("assertNotThrown failed: %s was thrown%s",
T.stringof,
tail),
file,
line,
t);
}
}
Specifically this line:
immutable tail = msg.empty ? "." : ": " ~ msg;
This should rather be:
immutable tail = ": " msg.empty ? t.msg : msg;
That way you get back the exception message if you haven't provided your own.
