Explanation: We write the acceptance test, then the unit test, then write the code to pass the unit tests, and then
pass the acceptance tests.
18. (3 pts) The single best predictor that a software project is likely to come in excessively over budget or late schedule
is:

19. (3 pts) Given the success rate of small software projects versus large software projects presented in class, what
technique that we have covered would give us our best chance at building a large project from many small projects?
def foo(x,y)
if x
if y
z()
end
else
if y
w()
end
end
end
# version 2:
def foo(x,y)
if x
check_y_z(y)
else
check_y_w(y)
end
end
def check_y_z(val)
z() if val
end
def check_y_w(val)
w() if val
end
20. (3 pts) The two pieces of code at right have the same logical
functionality but different structure. Which statement is TRUE
about comparing them?
# version 1:
def foo(x,y)
if x
if y
z()
end
else
if y
w()
end
end
end
# version 2:
def foo(x,y)
if x
check_y_z(y)
else
check_y_w(y)
end
end
def check_y_z(val)
z() if val
end
def check_y_w(val)
w() if val
end
