TDD

Agile without the right mindset and practices leads to building big balls of mud. – Declan Whelan, wrapping up OnAgile 2015 Today, I had the chance to go to my very first virtual conference — the OnAgile of the Agile Alliance, which of course means that I stayed at home. […]

WBITDD – Point of Sale #1 – Minimum Viable Product

Finally getting back to production code… and to the missing test case from four episodes ago. TDD doesn’t replace thinking! Hope I got it right this time. ► All Game of Life Episodes: http://goo.gl/xc59GX ► Let’s Develop! http://letsdeveloper.com ► Don’t Miss an Episode: http://goo.gl/whzDi1 «Conway’s Game of Life» The Game […]

Conway’s Game of Life #20 – Game Loop – Limiting ...

Mocking is a little ugly with generics, since we need to suppress some warnings. Using Mockito’s JUnit runner is a beautiful alternative way to create (and inject) mocks without these warnings! Definitely worth to know. ► All Game of Life Episodes: http://goo.gl/xc59GX ► Let’s Develop! http://letsdeveloper.com ► Don’t Miss an […]

We’re still refactoring out tests. This one got a special challenge: testing the order of call (you might remember: update must be called before render, to avoid lags). Mockito can check order, if you know how to tell it! ► All Game of Life Episodes: http://goo.gl/xc59GX ► Let’s Develop! http://letsdeveloper.com […]

Our tests are redundant and ugly, because there’s lot’s of boilerplate code for the stubbing. Let’s see if we can clean this up using a mocking framework. Not because it can do something we can’t, but because creating the stubs is less verbose and more flexible. ► All Game of […]

Conway’s Game of Life #17 – Game Loop – Mockito

4 Apr, 2015 in Conway's Game of Life / Let's Develop tagged Game Development / Mockito / TDD by letsdeveloper

Now for making our game loop catch up, if execution is delayed by other processes or a lazy CPU. A simple second test for our loop and we’re done. Right? Hell no, but I didn’t realize until much later… ► All Game of Life Episodes: http://goo.gl/xc59GX ► Let’s Develop! http://letsdeveloper.com […]

Conway’s Game of Life #16 – Game Loop – Framelimit ...

4 Apr, 2015 in Conway's Game of Life / Let's Develop tagged Game Development / TDD by letsdeveloper

Having clean tests, we can introduce the means to test timing behaviour in our game loop. It is important to introduce proper abstractions in order to write robust tests that control time. It’s conceptually easy, but often done wrong in practice. ► All Game of Life Episodes: http://goo.gl/xc59GX ► Let’s […]

We rushed along and accumulated some technical dept in our test suite. For the next feature I intend to implement, this is going to hurt us! So first thing to do is clean up the tests. ► All Game of Life Episodes: http://goo.gl/xc59GX ► Let’s Develop! http://letsdeveloper.com ► Don’t Miss […]
