Decision coverage - It checks whether every edge of the
program is covered or not i.e. each edge of every control
structure(i.e. IF and CASE statements)are covered or not.

Condition coverage - It checks whether every conditional
statements are covered or not. It evaluates for only true
and false condition for each conditional statement not every
edge of those conditional statement.

Decision Coverage
-----------------
1.Generally it says The test inputs to cover all
decisions(for ex:IF) will be in such a way that,those test
inputs can be able to make that decision block both true and
false.
for ex:
if(a>b)
print a;
endif
if (b>c)
print c;
else
print b;
endif
so here we should make test inputs in such a way that it
should able to make first if true and false although there
is no else condition.same for the second if block.
condition coverage
------------------
Here condition refers to the all possible conditions
existing in the program that we can traverse.
for ex:
if((a>b) && (b>c))

here inside the decision block there are conditions which we
should traverse.

Answer / priyanka agrawal

100% decision coverage is 100% statement coverage.but 100%
statement coverage is not 100% decision coverage.This is
because decision contains both true and false part.So 100%
statement coverage can not cover both true as well as
false.and if decision is covered that means automatically
the statement will be covered.
