Put all integers from 0 to NxM-1 into an array, shuffle that array randomly and pick the results one after another (mapping to row/column could be anything trivial like row=idx mod M , col=idx/M). A …

Instead of giving you an academic definition I will try to show you some of the differences using a real world example using VBA: Early binding: Dim x As FileSystemObject Set x = New FileSystemObjec …

I don't know what Jim Perry meant, my mindreading capabilities are very restricted. Actually, I disagree to his literal statement: even in a hypothetic "more realistic context" an expression like if …

You are not the first who stumbled over the fact TDD misses a solution finding phase. Here is a link to a german blog summarizing a whole article series of Ralf Westphal about the topic. If you don't …

If the only thing you want is to test if all those error messages are correctly customized, there is a way more efficient solution to this than to invest months of work to create test scenarios for ea …

Why not just stick with that term? It may not be 100% appropriate, but when you choose a different name that will probably a cause of more misunderstandings than the ones you try to solve. Designers o …
