有没有关于“pytap” TAP发射器的有效示例？

Question

如果我们看看例子3：

#TEST SOME STUFF
from TAP.Simple import *

plan(3)

def in_between(value, bottom, top, msg):
    ret = ok(((bottom = value) and (value = top)), msg)
    if (not ret):
        diag("value %s is not between %s and %s" % (value, bottom, top))
    return ret

in_between(5, 3, 10, "5 is OK.")

in_between(5.5, 5, 6, "5[2] is OK.")

# This will fail.
in_between(1, 20, 30, "1 is in range.")

我想看看如何用真实的Python代码来实现这个

注意：ret = ok 这句代码里有 <= 和 =>，而不是单纯的 =，因为代码没有显示出来，所以我把它们去掉了，我也不太确定怎么处理这些符号

这里有一个可以作为参考的例子。

Answer 1

好的，我自己搞定了，主要是参考了perl的TAP示例，然后把它改成适合Python的方式。

#!/usr/bin/env python
import TAP

ok = TAP.Builder.create(3).ok
def hello_world():
    return "Hello, World!"
ok(hello_world() ==  "Hello, World!", "First Test")
ok(hello_world() is  "Hello, World!", "Second Test")
ok(isinstance(hello_world(),str), "Third Test")

解释：

1. 首先，你需要在你的电脑上安装TAP，然后用import TAP来引入它。
2. 接下来，ok = TAP.Builder.create(3).ok这行代码中的3表示你打算进行3个测试，后面的内容就会自动跟着这个数量来。
3. 第一个测试需要用“代码”，然后是条件（==），最后是你期望的结果。

对于is或者isinstance()也是一样的道理。
