Won't this race with importing and intermittently fail?

brunoerg commented at 2:02 PM on February 4, 2025:

You're right, could happen. I just added a try/except around it, now it checks the duration is greater than 0 or if the field is not returned into getwalletinfo response.

ACK bb0879d

The test looks good as it improves the verification of an RPC call field. However, the verified field produces different values depending on the scan situation:

"scanning" : { (json object) current scanning details, or false if no scan is in progress>     "duration" : n, (numeric) elapsed seconds since scan start     "progress" : n (numeric) scanning progress percentage [0.0, 1.0] },

I believe this PR would be more complete if it also verified the false case—for example, when importing the p2pkh descriptor for the first time (around line 108).

hodlinator commented at 1:16 PM on February 13, 2025:

nit: Seems a bit heavy-handed to use exceptions, even if it's following the pattern of code above?

            scanning = wallet_info.get("scanning")
            if scanning:
                assert_greater_than(scanning["duration"], 0)

Could also break out encryped_cli = self.nodes[0].cli("-rpcwallet=encrypted_wallet") for the entire block now that we are using it for a 4th time, if you re-touch.

Good suggestion, but I will leave as is for now to not invalidate the reviews. Thanks.

Post-merge ACK bb0879d

Small improvement suggestion; also testing that the progress is between 0 and 1.
```
progress = wallet_info["scanning"]["progress"]
assert_approx(progress,0,1)
```
