我试图计算斜坡的截距,但是我不能测试所有的测试单元。我得到的第一个测试单位工作,但最后一个我有一些麻烦。有人能帮我找到错误吗?

def test(actual, expected):

“”” Compare the actual to the expected value,

and print a suitable message.

“””

import sys

linenum = sys._getframe(1).f_lineno # get the caller’s line number.

if (expected == actual):

msg = “Test on line {0} passed.”.format(linenum)

else:

msg = (“Test on line {0} failed. Expected ‘{1}’, but got ‘{2}’.”

. format(linenum, expected, actual))

print(msg)

def slope (x1, y1, x2, y2):

x2 = (x2 – x1)

y2 = (y2 – y1)

m = (y2/x2)

return m

def intercept(x1, y1, x2, y2):

m = slope(x1,y1,x2,y2)

b = y2 – (m*x2)

return b

def test_suite():

test(intercept(1, 6, 3, 12), 3.0)

test(intercept(6, 1, 1, 6), 7.0)

test(intercept(4, 6, 12, 8), 5.0)

test_suite()
