Programmer Test Principles (Kent Beck) alvin July 5, 2019 - 10:05am

Kent Beck has a good article on Medium titled, Programmer Test Principles.

This is a page from my book, Functional Programming, Simplified

ScalaCheck 2: A More-Complicated Example

“But I was trying to think why I don’t use QuickCheck — which is a very nice tool — more. I think it’s because the situations that cause me trouble are ones that I would find it difficult to generate test data for.”

Simon Peyton Jones, in the book, Coders at Work

In this lesson I’ll share a non-trivial example of how I used ScalaCheck to test a function I wrote recently.

ScalaTest 112: How to run ScalaTest unit tests in Eclipse

Problem: How do I use ScalaTest in Eclipse (or, How do I run my ScalaTest unit tests from Eclipse?)


I do a lot of work from the command line with Ant builds and similar things, but there are times I like to do things through Eclipse. Today I wanted to run my ScalaTest unit tests in Eclipse, and found this to be a straightforward task.

Besides Scala, Eclipse, and an Eclipse project, you'll need:

CakePHP automated web testing with SimpleTest

CakePHP/SimpleTest automated web testing: Can you share an example of some automated CakePHP SimpleTest web tests?

Sure, here's a quick look at how I've created a suite of CakePHP automated web tests using SimpleTest to perform integration testing on a new CakePHP web application.

The recipe for creating automated web tests in CakePHP is fairly simple:

CakePHP web testing - deleting database test data

CakePHP delete database test data FAQ: How can I delete CakePHP test data from my database in automated CakePHP unit and web tests (integration tests)?

I recently created a large set of CakePHP unit tests and CakePHP web tests (essentially integration tests), and as part of thorough testing, I needed to be able to create some user accounts and insert some test data into the database.
