(FOR PYTHON) Write functions testQ1(), testQ2(), and testQ3() that test your Q1, Q2, and Q3 functions on a variety of input values. For example, for some imagined function foo(n1, n2), a test function and its output might be:

Note: most good test functions should contain more than three tests!

Solution

def Q1(a,b):
   return a+b

def testQ1():
print(\"Q1(2,3) returns {}\".format(Q1(2,3)))
print(\"Q1(5, -1) returns {}\".format(Q1(5, -1)))
print(\"Q1(100, -23) returns {}\".format(Q1(100, -23)))
print(\"Q1(200, 0) returns {}\".format(Q1(200, 0)))

def Q2(a,b):
   return a-b

def testQ2():
print(\"Q2(2,3) returns {}\".format(Q2(2,3)))
print(\"Q2(5, -1) returns {}\".format(Q2(5, -1)))
print(\"Q2(100, -23) returns {}\".format(Q2(100, -23)))
print(\"Q1(200, 0) returns {}\".format(Q2(200, 0)))

def Q3(a,b):
   return a*b

def testQ3():
print(\"Q3(2,3) returns {}\".format(Q3(2,3)))
print(\"Q3(5, -1) returns {}\".format(Q3(5, -1)))
print(\"Q3(100, -23) returns {}\".format(Q3(100, -23)))
print(\"Q1(200, 0) returns {}\".format(Q3(200, 0)))

testQ1()
