O’Reilly Media, “Testing in Scala” (as of 2017-08-09 with a state-of-the-art sbt, it’s in a messy state and I cannot start sbt with the project files supplied – so I abandoned this path i.e. this book for the time being):

• http://shop.oreilly.com/product/0636920022602.do
• the book’s product page has a “Download Example Code” area: https://github.com/dhinojosa/testing-in-scala-book
• the book’s product page has a “View/Submit Errata” area (but there are only “unconfirmed errata” – “confirmed errata” are not available at all): http://www.oreilly.com/catalog/errataunconfirmed.csp?isbn=0636920022602

• Today (2017-08-09) I downloaded sbt-0.13.16.tgz and also scala-2.12.3.tgz, and I unpacked them on my MacBook Air at $HOME/usr/local/:

• $HOME/usr/local/sbt/
• $HOME/usr/local/sbt/bin/sbt
• $HOME/usr/local/scala-2.12.3/
• $HOME/usr/local/scala-2.12.3/bin/scala
