I started reading your Unit Testing Book yesterday, we have a lot of unit tests here, there is a lot to be desired and we are rethinking how they are implemented. Hoping to gain some insight.
I've only gotten through Chapter 2, but the thing that strikes me most... is we lost track of 'how to code' and so the unit tests are lousy as a result. For instance... our methods got very complex and lost sight of the "do 1 thing and 1 thing only". Unit testing seems to force you into a certain mindset when you start out the coding.
I have a question though, if most methods are refactored to do 1 thing only, then the high level methods are more "correct" by virtue of calling tested units and being simple. BUT... is there still a value to testing those methods which call into the simple units, or is that left to the QA department's functional testing? The underlying question here is, will that affect my code coverage metric adversly?

And that is the $20,000 question. Here's my 2c:
OK, let's say you are ultra-super disciplined and your lowest level methods don't have any conditional logic, no looping, nothing but "here are the inputs, here's the output." So that's the Holy Grail of unit testing not necessarily doable or meaningful.
The second level is that we allow some basic conditional logic and some basic looping. OK, now the unit tests are a little more meaningful and still "controllable" in that we can usually provide all the test cases to test each branch and iteration / recursion, as long as the functions are small enough.
What then? Well, can you organize your higher order functions somehow? For example, those that simply perform a workflow. It's easy enough to write a unit test that the workflow does what it's expected to do. What about more complex conditions? Those are unit testable too -- again the idea is to keep the functions small so that there aren't too many branches that need to be called. And furthermore, and most importantly, branches should not contain any statements other than a call to function to do something on that branch. No nesting, no inner looping, nothing but if-call-else-call. Rinse-and-repeat as you go up the food chain, keeping functions with conditionals and looping small, realizing that you don't need to test the lower level calls, only the higher level results.
At some point, the cost of unit tests becomes too high, which is a good time to switch over to the "if it broke, write a unit test first to recreate the problem" mode. That way, it's really cost effective -- you're fixing only known bugs and adding to your test suite.

They do indeed!
Does that help?

Yes indeed. Helps to clarify the fuzziness of when and how to test.
Thanks!

Yeah, I like how they handle the visualizations of subtasks, etc. There's a few features I wish it had, like task dependencies, but overall it's quite fun.

I had a car swerve in on me and attempt to hit me and I was cited (as a cyclist) I now have my go pro on universally. Unfortunately, most police don't like bicyclist either. Now that I am go pro'd and lawyered up I can finally cycle without fear.

I'm pretty sure the camera won't do anything to reduce the risk of someone in a car or truck running you over. After the fact it might help your estate sue the moron for everything he owns, but you'd still be pushing daisies.
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, waging all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

I know 'p**t' but all I can think of for 'p***k' is 'plank' which maybe for a Daily Mail reader is a bit down on the streets!
Someone educate me!

I find the road markings to be confusing as hell. Are they bike lanes or bus lanes? At one point the road has clear car lanes, but at the intersection, the bike late becomes as wide as a car lane?
Also found it comical that the bicyclist is annoyed at a car in the bike lane, but appears to have road in the car lane.

I was driving into work one day and there was a bicyclist in my lane one day, because there was a marked bike trail that was parallel to the road a right off the curb. I figured he was attempting to cross the lanes to get to the other side. As I enjoy bicycling myself I wanted to be courteous. So before switching lanes to avoid either one of us swerving into each other I tapped the horn to let him know I was there and I passed without incident.
While waiting at the traffic stop down the road the bicyclist pulls up alongside my car raps the window hard and flips me the bird while screaming about his rights to ride on the streets and heaven knows what else and then proceeds through a red traffic light. Elephanting arse!
Seeing this video allowed me to project my fustration on that guy. I do not advocate violence by any means but sometimes when two angry people cross paths there is that guilty pleasure of seeing them pummel each other and vicariously satisfy the resentment that one feels for people like them.
It was broke, so I fixed it.
