High Line by David Berkowitz

How will Continuous Delivery affect network traffic?

I was recently in New York and had a chance to walk along the High Line. The High Line is a disused overhead train line converted into a walkway and park. It’s a really lovely walk.

I was interested to learn that the train line had been built in the 1930′s but had become disused by 1980′s. It’s main purpose had been to transport meat and produce to manhattan from the upper west side. With the advent of trucks the train line fell into disuse. It was about to be torn down when a small group of inspired locals advocated it be turned into a park. The movement grew and now the disused train line is a lovely walk and respite from the busy traffic.

I think it’s interesting that the train line fell into disuse in the first place. Why were so many companies eager to drop the train line in place of trucks? My guess is they wanted the ability to freight cargo when they wanted. Rather then delivering in one bulk they delivered smaller amounts more frequently. That way they could become more responsive to their customers needs.

That’s what we’re aiming to do with continuous delivery. We want to   be able to deliver in a faster way, to be more responsive to our customers needs.

World Class Traffic Jam by bk

I wonder if our existing network will be able to handle it though? Look at the traffic jam that is NYC and it makes me wonder that with the ability over faster and more frequent delivery comes the cost of greater traffic on our networks. Remember, if it was just your company wanting to deliver, of course there’s sufficient bandwidth, but when everyone has the same idea will our current network be able to handle it? I  guess only time will tell!

 

My Testing Manifesto 2014

It’s my first day in permanent employment for, oh, about 20 years. I feel a little giddy, like someone’s first day of school – nervous but excited.

Unlike my first day of school, I have some clear goals and ideas I want to implement. I thought I might outline them here to help remind me of what I want to achieve and also to see how different it turns out.

Testing Philosophies

Testing is an skilled activity(not a phase) that all, to some degree can acquire.
Testers need autonomy to make decisions, to develop and perform excellent testing.
Quality is something we all care about, though it means different things to different people.
Every test has a cost (design, building, maintaining, reporting)

Goals for Testing

To develop a company wide reputation for excellent testing
To develop a test team that is able to handle testing problems with courage, skill and humility.
To coach and help develop the skill of testing with whoever may need it
To identify where testing is occurring and help augment that
To develop and the grow the test team in size, skill and expertise.
To engage with and support the testing community

Personal Goals

To acquire knowledge in testing within a continuous deployment, delivery environment
To learn more about functional programming
To be able to identify how to repair code
To work with integrity and within the bounds of what I consider ethical

Dropping the Ball

Does the thought of ‘dropping the ball’ fill you with dread ?  Perhaps you feel you will let people down, or more importantly yourself?

Here’s a thought experiment: What if you actually let the ball drop? Do you know what might happen?  Will the sky fall?  Are people let down?

If so, is that so bad? We all fail at some point in time in our lives. We don’t expect perfection from others, but for some reason expect it from ourselves. But that’s not physically possible is it?  Expecting perfection in this way is about as practical as promising perfect software right?

So next time your spreading raspberry jam too thinly consider giving yourself permission to drop the ball. After all as a tester you owe it to yourself to try, don’t you?
