Using battle_tested to feel out new libraries.

battle_tested doesn't necessisarily need to be used as a fuzzer. I like to use its testing funcionality to literally "feel out" a library that is recommended to me so I know what works and what will cause issues.

Here is how I used battle_tested to "feel out" sqlitedict so when I'm using it, there aren't any surprises.

First, lets import SqliteDict and make a harness that will allow us to test what can be assigned and what will cause random explosions to happen.





In [2]:



    


from sqlitedict import SqliteDict

def harness(key, value):
    """ this tests what can be assigned in SqliteDict's keys and values """
    mydict = SqliteDict(":memory:")
    mydict[key] = value

Now, we import the tools we need from battle_tested and fuzz it.





In [3]:



    


from battle_tested import fuzz, success_map, crash_map

fuzz(harness, keep_testing=True) # keep testing allows us to collect "all" crashes



    


















    






testing: harness()
tests: 0              0/sec - 2s
