TDD Starter Kit

The easiest way to start writing tests

Create your own personalised starter project with dependencies, folder structure and compiling, working code

Nothing beats code that 'just works'

Give me something that works out of the box so I can start playing with it as soon as possible. Don't force me to wonder:

  • Which project type do I need to create?
  • What should the folder structure of the project be?
  • Does this file need to be on the classpath or just the filesystem?

And the classic: Where exactly do I put this block of text you've just shown me so that I can see the thing you're explaining to me?

Developers need working code that runs, not context-free snippets of text.

With concrete working examples that run, you can experiment and play with the code to get real objective feedback.

And with feedback you can learn.

  • How does this function work? Try it and see.
  • What does this framework do? Try it and see.
  • What happens when I do ... ? Try it and see.

Try it and see ... don't read about it.

For Java software development today, this usually means having a complete project setup and running in your IDE with all the required dependencies.

So, to get to where I can 'try it and see', I keep a little starter project ready in source control.

There are many ways to set up a project to start writing tests in Java (I'm a huge TDD fan).

Here's just one of them.

What is it?

A git repo with:

  • working test and production boiler-plate code that demonstrates how to use JUnit and Hamcrest.
  • my recommended folder and package structure
  • gradle wrapper and build script to manage dependencies and generate IDE specific project files (useful when pairing with someone who uses a different IDE)

Just clone it and go.

$ git clone [email protected]:michaeldeluna/tdd-starter-kit.git

Do you always use the same set of frameworks or have a preferred project structure that you have to repeatedly construct by hand each time you start a new project or simply want to try something out?

Why not build your own custom project and check it into source control?
