Despite 1.33b being awesome, I'm using it in parallel with R# 5.1's runner at the moment because it has some killer features, one of which is debugging a test.
NCrunch's red cross markers to say exactly where the code failed are brilliant, but the tooltip is tricky (really small mouse hit area and you can't dig into the information) and it doesn't give you any information about variable values at the point where the test failed.
To be honest, this alone (without a debugging session) would be a godsend: hovering over code after a failed test run, to be able to watch the values, would be an incredible time saver.
But I appreciate this is wildly difficult to do without VS being in 'attached mode', and would be akin to rewriting VS's watch system. However, at least if VS were instead to be able to easily attach to the NCrunch test runner - perhaps (oo!) with NCrunch having automatically set breakpoints on the lines it already knows were associated with the failures, that would be like a single button to take you straight into a scenario where you can investigate the problem.
p.s. ..Can I buy shares in NCrunch? :P
