Loving the gotopia.eu setup by @GOTOcon. Such great talks. Enjoyed seeing @AzureDevOps showing up in a great talk about templates.

You can have "E2E Testing Strategies" or "Microservices" but not both.
Microservices are, by definition, "independently deployable" so you don't get to test them together before you deploy, because if you do you now have a distributed monolith - which is fine, but not m-service
@samnewman, I have read a lot about microservices but one topic I haven't seen much is end-to-end tests approaches for when start to adopt eventual consistent architectures. Your testing strategy has to evolve accordingly, adopting new expectations, but I wonder about strategies

"It didn't work" is not enough.
READ THE ERROR MESSAGE.
Understand what it means.
Now you know more, with more certainty, about your environment.
Let's not do "programming by permutation."

Estimating story points does not add value. Stories are small. And there are many. Which means the Law of Large Numbers applies. Which implies that the result of repeating the same experiment enough times will be close to the average.

Agile has nothing at all to do with "twice the work in half the time." Twice the garbage in half the time benefits nobody. Focusing on output is snake oil.

Environment Branch: Configure a product to run in a new environment by applying a source code commit.
A bad smell, only useful as a temporary jerry-rig

When testing your APIs, verifying the response code is not enough, and we're much too lazy to write assertions for *every* property within the body.
This is where Approval Testing really shines.

pro tip: this is a very bad idea
heavyweight change process leads to slower releases AND INSTABILITY
keep up regular releases. slowing down will give you a bigger code release, larger blast radius, higher likelihood of failure, harder debug
things are hard. let's work together

Have you heard the expression Cross Functional Requirements (CFRs) to talk about all the -ilities? 10 years ago today I coined it.
Reflected on 10 years of CFRs here: sarahtaraporewalla.com/agile…

Ha!
SAFe is not anti-agile, just as the lion is not anti-zebra.
It roams the countryside, devouring all agility it encounters.
