How could Reflection not lead to code smells?

Question

I come from low level languages - C++ is the highest level I program in.

Recently I came across Reflection, and I just cannot fathom how it could be used without cod

Unit testing software and frameworks like NUnit use reflection to get a list of tests to execute and executes them. They find all the test suites in a module/assembly/binary (in C# these are represented by classes) and all the tests in those suites (in C# these are methods in a class). NUnit also allows you to mark a test with an expected exception in case you're testing for exception contracts.

Without reflection, you'd need to specify somehow what test suites are available and what tests are available in each suite. Also, things like exceptions would need to be tested manually. C++ unit testing frameworks I've seen have used macros to do this, but some things are still manual and this design is restrictive.
