How to unit test abstract classes: extend with stubs?
...his.. but to truly test any derived class you are going to be testing this base functionality over and over.. which leads you to have an abstract test fixture so you can factor out this duplication in testing. This all smells! I strongly recommend taking another look at why you are using abstract cl...

Let's look at it another way - in base 10 which you're likely to be comfortable with, you can't express 1/3 exactly. It's 0.3333333... (recurring). The reason you can't represent 0.1 as a binary floating point number is for exactly the same reason. You can re...

...nge of variable. Let m = 2ⁿ. Then n⋅2ⁿ = ( log₂m )⋅m (taking the base-2 logarithm on both sides of m = 2ⁿ gives n = log₂m ), and you can easily show that m log₂m grows faster than m.
