Does Garmin test software releases?

Forgot to ask ... in the scenario where the device decides to reboot itself while recording an activity, I noticed that it does not resume the activity automatically, but it gets paused. Is that the expected behaviour?

Welcome to Garmin. Sent my 530 back. It sucked!  Numerous issues as forum supports. Read below. Had same issue along with freezing, Strava segments PITA, zooming out, wrong trail names, battery, gps distance way off, forksight didn’t work, etc  used 4 times back to Wahoo ELEMNT

Well, based on my own experience with various garmin devices, and by visiting the forum frequently, I have reasons to believe, that at least some features ARE NOT TESTED AT ALL before release. Either this, or garmin deliberately releases software with well known deficiencies.

Well, no matter how many testers you have, it won't compare to releasing an update to thousands of people. 

My criticism would be that Garmin should become more focused. The 830 and 1030 could probably have been a single unit (let's call it 930). So they could have 930, 530, 130 and that's all the Edge computers they need. Wearables? Same deal. There's so many of them and they can't keep them updated properly and the mobile connectivity simply isn't amazing. 

As for user experience, I've not had a single reset during a ride, but I'm disappointed with the unit's poor connectivity. 
But  I guess the whole GPS cycling unit market is pretty immature. Even Wahoo has their issues - for example some people are still reporting problems with rides longer than 3 hours, even though it should have been fixed in an update several months back I believe. And there are some inconsistencies and issues with the altimeter, especially when you decide to take the unit off road. There is the occasional issue with the buttons peeling off and let's be honest, the price of the Bolt should have been considerably lower by now. 

My point isn't that one brand is worse better, my point is that paying this much money for a bike computer gets you exactly this. There's nothing better right now, and unless there are some considerable policy changes, there probably won't be. 

Garmin also makes avionics for planes and I believe they have the biggest market share for avionics.  You can bet they test their avionics before they release them!  Okay, consumer products will never reach the reliability of avionics but the current quality gap is staggering.  I hope Garmin will make a concerted effort to improve its consumer products.

You make the bolt sound massively inferior but my question to you is have you ever used one?

For me it is much better than the 530 I just purchased. The Garmin is actually pretty poor in comparison to it, and loads more expensive.

The only reason I got a 530 was for the external battery support (I am doing a 1200km ride next month) and because I managed to break a bolt. However, it got replaced for free under warranty.

After my 1200km ride I am going to sell it because it’s nowhere near as good. Not even close.

For every Garmin that was released until now, firmware was stable after ~2 years , almost when it was replaced by another model 

The Bolt is inferior to the 530 feature-wise. I own one. Currently, the Wahoo app on my phone is broken since the update 3 weeks back. It keeps crashing any time I go to edit a setting. Given the phone-based setup, this means I can't edit any data pages until they fix their app. Wahoo also relies on 3rd parties for everything. Strava, RideWithGPS, TrainingPeaks, etc. Meanwhile, you can get all of that for free with Garmin Connect. Add in that maps are a lot harder to read. due to the B&W screen, it's not all what I thought it'd be. When the app was working, was it fine? Sure. But not something I'd consider extraordinary. 

I just ordered an Edge 530 to replace it.
