defect:  description, step by step how to reproduce it and defect id, envi, seve, module, project, status

test case: document  that with a given data and initial conditions, the step by step execution of user actions and expected result.

many test case strategies:

BVA: check for boundaries , corner case  for a text fireld designed to enter 1-10
  boundaries : 0,1,10,11
ECP: devide in to partitions of valid and invalid data:
valid: 1,5,10   invalid:  -1,12
state transition:   result of different sets of data like cc, home  cf, login invalid  ee error msg,

decision table: combination of data in a chart like login functionality
login               c as correct   f as false data
                       c f,    c blank,  f c,  f blank,  blank blank, f f, c c, blank,c   blank,f
password    
 9 combinations..

error guessing


Use case testing: test with system and actor with d/f operations..
Static testing: Code review , inspections ,walkthroughs , technical review are some static testing methods.
