Quote: Technically, if you needed fake DB data that would be a fixture. But, a unit test shouldn't call a live resource. You can't do gated check-ins that way as it would take too long to run thousands of tests.
This is why I always, always, always advocate a dev/stage/prod setup, esp for web applications.
Dev has the "same server software", but may have data quality issues, maybe the odd broken dependency here and there, but usually nothing that the development team in general can't fix. It irritates the hell out of me, when corp/internal I.T. and the business, mandate that the same "I.T. security policy's" regarding admin access should be applied to developer only instances, as if they where prod.
Staging, should always be a "clean" dev copy. Software should be as close to prod as possible, deployments should ONLY be to staging after seniors on the dev teams have verified that the code is sound, working and potentially ready for prod.
Prod, well I don't need to state anything about this one 
My point here is that, it should be perfectly acceptable to use "Live" resources, if you have a proper dev/stage/prod set-up.
If data quality is a necessity, then there are ways to easy mirror a live DB to the dev & stage environments, while maintaining PII security, such as redacting information with stars as it's copied across, that way the data "format" is preserved well enough to work in testing.
In many of the projects I work, I go in, and build the dev team myself, usually a very tight knit bunch who've all worked together before, and who bounce off each other very well. If it's not a large project, or a simple desktop app that one dev can handle, I'll run the entire project myself, so I don't often find myself in a situation where I have a very large team to co-ordinate with.
The last time I found myself in that environment was back when I worked FT for a single corp, and as a corp I had to follow corp policy's, if they mandated TDD down to the bone, then it was TDD down to the bone.
These days I much prefer the consultancy life style, where I go in, advise, build, test after it's built then move on to the next exciting project

Fo sho man. Totally agree on the 4 environments that should be set up. You can get away with 3 if you're a solo dev in the company, but otherwise 4. My point was more about calling a live resource for a unit test makes them no longer pure or deterministic and very slow to run. By live that could be a dev environment as well, as in an actual API call.

It's so hard to find that too. Real hard. But when you have that camaraderie it's gold. Usually it seems everyone is unhappy and hates life and has an agenda rather than the love of tech.

IMO a lot can be learned from that. Like, if you have a team that refuses to modernize, you're stuck in one spot. Also a lot can be learned from sticking with a project for years, usually about supporting it, but a lot can be learned. I choose the former too though, if given a choice. I wouldn't want to be beholden to people who stopped learning and are content with that.

Started writing some Unit Testing year ago and found that with the services I develop, unit testing is futile. That said, I have my own extremely broad testing infrastructure that is constantly running JScript and PowerShell generated client requests against my servers, some of those requests intentionally contain client request errors that we've seen come from specific client types. If you are dealing with library functions and methods that have fairly simple input parameters, Unit Testing can be useful. When dealing with a client server model that takes a wide variety of complicated XML HTTP posts, from various vendors, all of whom implement specifications differently, not so much. Most of the problems would be caught somewhere else farther down the stack. That said, I have a variety of iOS clients to test with since Apple's developers excel at not following specifications, especially when it comes to return codes.

Yes, but nothing formalized. None of this automated stuff the kids do these days.
Frequently, when developing an SQL function (in SSMS), I'll add some calls to the function in a commented-out area so I can test it and remember what some of the known edge cases are.
I wish there were a way to do that for C# in VS.

Doesn't VS offer some sorta doxygen style comments? That's a great idea and I do the same in Node with jsdoc style comments. For VSCode at least, it has the bonus of also showing the example uses or edge cases via intellisense too.

I think it's things which get executed at compile time, but I would want to have the ability to execute ad-hoc tests whenever I like.

I really like using unit tests especially when I am working on some new algorithms. I can test instantly without firing up the GUI and entering the data manually. Helps me find the inverted logic and poorly managed edge cases (hey, sometimes I rush it a bit when I get excited!)
Other people's unit tests have saved my bacon many times. "Well, this is an obvious bug that needs fixing" followed by failed unit tests has led me to learn a lot more about some seemingly innocuous code. I usually add comments so future devs don't make the same mistake, btw.

Unit testing: very much yay.
I've been doing unit testing steadily since about 1999. I have my own simple unit test driver. Tests are static member functions. It can all be statically linked with an executable. No tests enabled equals no overhead in size or time. The two places I've worked that did unit testing also had the highest code quality of the places I've worked. I've used a couple of open source frameworks for unit tests, but they seemed unnecessarily complicated to me, and it's annoying to have to separately compile test executables. Writing unit tests helps me wring out my designs and of course avoid regressions when I change things (which happens all the time).

Noice. For me it's only been a few years, but the more I do it and the better I get at it, the less of a chance of ever turning back ya know.

Oh yeah, that is one one of the caveats I faced in a C project once. The way I handled it was to have my overall build command just compile both. Probably harder to get away with that for C++, so cool idea.

Had to implement a globally unique ID generator that would work in distributed/disconnected system for a project in TS today. Doesn't warrant an article (I think??), so here it is if anyone wants it. Much like YouTube IDs, etc. the result is in base62 to keep it as short as possible. Runs fast enough to generate 100,000 IDs in 340ms in a WSL environment.
Big ol' edit: Made this a tip/trick. Nothing to see here now. La la la.

Of course it does...
Low-code tools boost developer productivity[^]
"Over 90 percent of respondents to a new survey say that low-code tools have boosted developer productivity in their organizations. 43.5 percent of developers are saving up to 50 percent of their time when they use low-code tools on a project."
I keeping thinking one of these days I will actually find an organization that actually measures developer productivity. Or devops. Or IT. Or DBAs. Or CEOs.
Now Sales ... those guys have it down ... 'how many contracts did you sign last month?'
But back to the article ...
""Low-code software has real value in democratizing software development to include non-developers," says Jason Beres, senior VP of developer tools at Infragistics, and creator of App Builder software."
Any one want to guess what Infragistics sells? Come on - I dare you.
The 'story' is based on a study created by ... bet you can't guess!
"The full report is available from the App Builder site."
