c# - Could some one check for me if my unit test for the FillUpWater is correct -


could tell me correct unit test fillupcontainer()?

namespace coffeemaker {     [testclass()]     public class watercontainer     {         //private watercontainer waterc;          watercontainer waterc = new watercontainer(0);         int level = waterc.level;          [testmethod()]         public void fillupwatertest()          {                                                   if (waterc.level == 0)             {                 bool result;                result = waterc.fillupwater();                             }             level.equals(5);         }     } }

no, it's not. level.equals(5) not assertion, it's expression, result of throw away not assigning anything.

a better test might this:

[testclass()] public class watercontainer {             [testmethod()]     public void whenwatercontainerisempty_fillingitup_causescorrectwaterlevel()      {                                               // arrange         watercontainer water = new watercontainer(0);         // act         water.fillupwater();         // assert         assert.areequal(5, water.level);     } }

notice method name describes what's being tested, , test self-contained (all local variables).

the assert statement cause test fail if water level not correct.

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
