To me it has very little to do with how they would test their application but rather how they work. Developers are expensive resources and if a touch screen will allow a given developer to work faster or even just make them happier then it is worth it.
Now with that said I would say it depends on whether they are working with a desktop or a laptop. I am always surprised when a developer uses a desktop but I know it still happens. To me on a desktop it is irrelevant but on a laptop it is useful.
That is my 2 cents!

you developing something for a desktop with touch interface?
If just developing for mobile devices, maybe touch screen not needed and emulation enough.

No. But I can see your point. If yes, a touchscreen is necessary.

I cannot say for developers in general, but I do use my touch screen (laptop screen) during development occasionally.
When I develop using Xamarin.Forms, I make sure I develop for handsets (iPhone, Android) and tablets (iPad, Android, and Windows/UWP). Even with emulators, I like to test the "look and feel" of my screens. At least then I can catch and fix the more obvious issues before finally getting on to testing with actual devices.
If you need a touch screen, use it.
If you don't need a touch screen now, but may likely need it in the future, at least have it.
If you don't need a touch screen now or ever, don't get one.

ABSOLUTELY. Intentional caps. Things that are trivial with a mouse "touching" an emulator fall down badly when trying to use a finger. Of course, my code runs from 3.5" to 15" touchscreens, so I have a few t-shirts about learning the hard way...

If you are developing a touch-centric application, it sure helps to have a touchscreen. In one project I developed a BI dashboard for a wall-mounted 1080p touchscreen monitor. It supported 10-point multi-touch using Google Chrome in kiosk mode. Having a touchscreen directly connected for debugging and js object/event review was critical.

Sounds like an awesome BI dashboard, did you use a framework or build your own? any tips would be appreciated!

The short story is that existing dashboard frameworks (that I could find) were geared toward providing the data presentation tooling, and we were looking for something that would primarily allow us to layout our data presentations of choice. So I built a container system that let us put any kind of web content from anywhere within a completely flexible layout. It ended up working across screen sizes of any kind and orientation even though it started as strictly a 1080p display.
It was basically one big single page application using MaterializeCSS for navigation and styling. I used HighCharts, d3.js, plain-old HTML, and SVG for most of the data presentation.

No. Actually no human using a computer needs a touch screen.
Using touch reminds me of the light pens used in the 1960's before the invention of the mouse.

Using this "vector graphics intelligent terminal" was the same as emulating an iPhone X with Super Retina display on a 1028 x 768 screen.

Yes - touch screens are getting more and more prevalent and we need to actually use our software as an end user will use it. Emulators only go so far - developers actually need touch screens on their development systems as well to help the emulators.

Rule #2: ignore any news story with "could" or "might" (or "may") in the title.

Sadly, that's most of what "science" news seems to be lately. Well, and anything Trump says.

Trump just omits the "could", "might" and "may".
Thinking about, it, doesn't that mean that Trump transports information more efficiently than scientists?

Sheesh, if they just got rid of facebook and 99% of the crap on utube and advertising it'd be 10000 times faster over copper.
Seriously though as computers/networks got faster (and storage larger) they've just found an equivalent scale of crap/bloat to put it right back where it was.
