Add listunspent() test for spendable/unspendable UTXO

joaopaulofonseca commented at 10:30 am on April 6, 2016: contributor

This PR adds a test on wallet.py covering the behavior of spendable/unspendable value for UTXO, when calling RPC listunspent.

This value should be different for address or private key import.

You may want to try assert_raises instead.

Nit: No need to shadow the original exception. You can just remove the try-except block altogether and only leave the sendtoaddress

Thanks for the tips. Fixed and rebased.

Thanks, Concept ACK.

I’m a bit divided whether I should propose to add this into the wallet test, which already uses listunspent. This currently adds some startup/teardown overhead (test takes ~9 seconds) just to test one call. I don’t feel strongly about that though. What do you think @MarcoFalke?

MarcoFalke commented at 8:34 am on April 15, 2016: member

startup/teardown overhead

I think such overhead is rather small. (Note that disablewallet.py runs in less than a second)

The overhead probably is caused by setting up the bidirectional connections and sync_all() calls.

I have not yet looked closely at the test (I try to avoid large diffs right now in the /qa subfolder as each patch may or may not silently conflict with the python3 refactoring work.) @jpdffonseca Would you mind to take a look if this can be neatly squashed into the wallet.py test, as suggested by @laanwj ?

joaopaulofonseca commented at 8:48 am on April 15, 2016: contributor

@MarcoFalke and @laanwj yes that makes sense. I will try to squash this verifications into wallet.py.

@MarcoFalke, after checking that wallet.py already covers some of the tests for listuspent(), I discarded the separate test file and merged the tests regarding the import of bitcoin addresses and private keys into wallet.py. The test execution time should remain the same.

MarcoFalke commented at 7:04 pm on April 18, 2016:

If you copied this function from elsewhere, wouldn’t it make sense to move it instead to test_framework/util.py, so the utility function can be used in other tests as well?

joaopaulofonseca commented at 9:26 pm on April 18, 2016:

Indeed.. It is used by multiple tests. I think it comes in handy for current and future test cases. If you guys agree I guess this could be moved to test_framework/util.py to be reused whenever needed..

MarcoFalke commented at 10:21 pm on April 18, 2016:

Sure, go ahead.

Moved assert_array_result() to test_framework/util.py.

I noticed that the previous method on receivedby.py had a bug when using the flag should_not_find. If the flag is set to True, the validation wouldn’t work correctly when the values passed as to_match are indeed found inside object_array, and no assertion is raised.
