java - how to unit test code that should cause compile error -

-



i have class take arraylist parameter:

public class foo {     private arraylist<bar> bars;      public foo(arraylist barlist) {         bars = barlist;     } }

there bug can pass arraylist constructor:

// should compile error line foo foo = new foo(new arraylist<string>());

the problem if add case test suite, when bug fixed, can not compile it. there anyway test case?

i don't know of language/unit test framework let "test" code should not compile. if can't compile it, there nothing test. can turn on compiler warnings when building. i'm pretty sure passing unparameterized collection big warning in jvm after jdk5.

python - Read npy file directly from S3 StreamingBody -

i have many .npy (numpy) , .json files saved in s3, need download , load these files. for json files downloading files , loading dictionary using following code: obj = s3.object(bucket, key) response = obj.get() body = response['body'].read().decode('utf-8') data = json.loads(body) that way avoid writing .json file disk , reading it. now want same .npy files, equivalent? currently downloading file, saving temp file on disk , loading np.load avoid if possible. following https://stackoverflow.com/a/28196540/3509999 : obj = s3.object(bucket, key) io.bytesio(obj.get()["body"].read()) f: # rewind file f.seek(0) arr = np.load(f) wiki

i start using kotlin , defined interface this: interface aadapter<vh : recyclerview.viewholder> { fun oncreateaviewholder(parent: viewgroup): vh fun onbindaviewholder(v: vh, position: int) } and when try use on code: class klasa ( private val adapter: aadapter<*> ) { fun dosth(){ //... val vh = this.adapter.oncreateaviewholder(parent) //on below line error adapter.onbindaviewholder(v, position) //... } } i error out-projected type 'aadapter<*>' prohibits use of 'public abstract fun onbindaviewholder(v: t, position: int): unit i tied add "in" or "out" definition i'm confused. how allow it. replace aadapter<*> aadapter<recyclerview.viewholder> . class klasa ( private val adapter: aadapter<recyclerview.viewholder> ) { // ... because have declared aadapter has type parameter vh type subclass of recyclerview.
