@alanpage It's very telling that manual testing is seen as cheap.

IME this perception exists because (as I have repeatedly seen at clients) the absolute most junior people are hired as testers in order to keep costs down. Because they’re so junior they don’t contribute very much. 1/2
@alanpage 2/3 They stay junior because they have no mentorship (because mentorship is expensive).

The “5x to 15x” cost of automation proposed by the OP fits with this model: median developer pay is around $150k US. A team of five devs then costs ~$750k annually (considering TC only here)
@alanpage 3/4 Glassdoor lists “QA Analyst” roles as starting at $18k US. I’m in NYC so this is lower than I’ve ever seen. Let’s assume QA roles start around $25k, which is just enough to rent a room and live paycheck to paycheck in NYC.

The cheapest QA analyst costs 17% of a dev salary.

Interaction Resiliency (iXR) is the practice of Software QA (aka #testing) as applied to "devops" or more properly Safety-II software delivery (aka continuous delivery & continuous deployment).
I put a name to "testing in devops" or "agile testing in continuous delivery" because a) those phrases are clumsy 😀 and b) the current discourse in #testing constantly collapses back on itself as big-A Agile + CDT are conflated time-and-time-again with Safety-II + Kaizen #iXR

Getting started with Want to succeed with #TDD ? Stop writing tests! @BurkHufnagel #TDD #DevNexus devnexus.com/presentations/…
We work with software that's way more complex than a simple shape like this. Reasonable people may see the same thing in different ways, based on their perspective! @BurkHufnagel #TDD #DevNexus
You have a goal that you share with me: you want delivering better code faster
... not *writing* code more quickly! @BurkHufnagel #TDD #DevNexus

Bir yazılım geliştiricinin bilmesi gerekenlerle ilgili 15 maddelik flood geliyor.. Mümkün olduğunca fazla keywordü bir araya toplamaya çalıştım.
Hadi Başlıyoruz!

#Developer #Software #Java #code #kod #yazılım #development #computer #bilgisayar #tool #PC #IT #web #tech #data
1-Temel veri yapıları (linkedList, map, tree vb) ve temel algoritmalar (sıralama, arama vb)

Sıfırdan kodlama ihtiyacınız büyük ihtimalle hiç olmayacak. Ancak ihtiyaç anında doğru yerde doğrusunu seçebilmek için o veri yapısının veya algoritmanın nasıl çalıştığını bilmeniz şart
2- Network Temelleri

OSI Modelini ve 7 katmanı; temel protokolleri(#TCP-IP, TCP-UDP, #HTTP, #FTP), güvenlik protokollerini(#HTTPS, #SFTP, #SSL), monitoring protokolleri(#SNMP, ICMP) bilmekte fayda var. Ayrıca ağ ekipmanlarının görevlerini tanımak ve 7Layer yerlerini bilmek lazım

Hey all #testing folk. I have someone in my team who loves working in #agile teams. But they're a senior tester, and they're not sure where they go next in terms of career ladder, esp as they're near the ceiling of what the role pays.
Part of me wonders if the answer to this is moving away from treating salary as hierarchical silos, and looking more at the person and what they contribute.
Hey @threadreaderapp can you unroll please?

The place where "testing vs. checking" starts to really leak (as all metaphors do but still…) is the Cartesian division of "things a human does" and "things a computer does."

First, Safety-II and therefore #devops, explicitly reject the Cartesian view of complex systems.
For instance the idea that there exists a computer activity called "checking" and what "checking" does is it validates assumptions.

There is a problem right there. Validation assumes some kind of goal-oriented behavior — telos — which computers do not on their own, have.
As covered pragmatically in the classic paper "The Ironies Of Automation" and further explored by Donna Haraway: computers on their own are not capable of "validation" because validation implies an understanding of some set of moral *values.*

But computers can't do that.
