Tests

My dear /prog/riders, what and how do you test and why?

Personally I prefer to skip unit tests entirely and focus on integration tests that will catch the same things that unit tests would minus time for writing bloat code for unit tests.

Who gives a shit about TDD?

THIS THREAD HAS CHANGED TOPIC

In this paper, we introduce a so-called Multistage graph Simple Path (MSP) problem and show that the Hamilton Circuit (HC) problem can be polynomially reducible to the MSP problem. To solve the MSP problem, we propose a polynomial algorithm and prove its NP-completeness. Our result implies NP=P.
SOMEONE EXPLAIN THIS SHIT
