Most all tests are successful
if you collect data. The question is if the test subject is successful.
Boeing has put the CST-100 Starliner's parachutes through their paces with a simulation of an abort early in the launch. While the calamity capsule has yet to make its first visit to the International Space Station (ISS), Boeing and NASA have pressed ahead with testing its systems, in this case checking that the parachutes …
SpaceXs Dragon capsule can still do a land landing. But NASA are not too happy (and perhaps SpaceX want to fast track?) with propulsive landings. Plus due to this no landing legs are attached.
I do wonder if it cold land on land with the chutes alone, or with a little help from it's Dracos.
IIRC SpaceX safes (and now permanently disables) the fuel pressurization system of the super dracos once it's in orbit, meaning that it can't do propulsive landings anymore. It definitely can't do a propulsive landing after an abort (because it'll have used most of the available fuel for the abort), which is another reason they went with chutes.
I'm assuming that it can land on land, although it would probably rely a lot on crush structures (crumple zones), if only in an emergency. Similarly, both Soyuz and Starliner are capable of a water landing, although it's non optimal. (So far, only Soyuz 23 has had to do a water landing because it landed in a lake).
I'd also assume that they've tested land landings, even if that just meant dropping one from a crane, but I can't find anything after a few minutes of searching.
"This demanding test program ensures Starliner can bring our astronauts home safe."
Safely, not safe -- it's an adverb modifying the verb bring, not an adjective.
As to their new craft, let's hope it doesn't have any undocumented features ala the 737 max -- 'no Dave, I don't think it's time to deploy any parachute at the momen...' [splat]
It doesn't appear that they have ever demonstrated all three parachutes firing yet.
Two parachutes doesn't behave the same as three. Will they actually open properly if all three deploy?
I've definitely seen more than one video showing parachutes getting entangled or otherwise failing to open because of being in a cluster.
