Question about Starliner thruster problems

On 28 June 2024, the NYT wrote:

Beginning next week, engineers will conduct ground tests at NASA’s White Sands Test Facility in New Mexico using a thruster identical to the ones on Starliner. The firings will reproduce the ones that Starliner performed in space.

That will probably take a couple of weeks, Mr. Stich said. “Then we’ll give engineers a chance to go look at that thruster,” he said. “This will be the real opportunity to examine a thruster, just like we’ve had in space.”


My question is this: Aren’t these the kind of tests that should have been done BEFORE even the first orbital flight test?
