The SPaMCAST 595 features our interview with Vladimir Khorikov. Vladimir and I geeked out on unit testing and his new book, . Our conversations covered the gamut with a discussion of writing from first principles, understanding and tuning the signal-to-noise ratio in unit testing, and tests that are better at proving the negative than the positive.  Vladimir Khorikov is a software engineer and author of several popular Pluralsight courses. He has been professionally involved in software development for over 15 years, including mentoring teams on the ins and outs of unit testing. He's also the founder of the Enterprise Craftsmanship blog, where he reaches 500 thousand software developers yearly. He started as an adviser on general programming topics, but lately shifted his focus to unit testing with a central message of teaching software developers how to make unit testing painless. The biggest advantage of his teaching style, and the one students often praise, is his tendency to have a strong theoretic background, which he then applies to practical examples.
