Writing Avocado Tests
We are going to write an Avocado test in Python and we are going to inherit from avocado.Test. This makes this test a so-called instrumented test.
我们打算写一个用python写一个avocado测试，而且这个测试类继承自avocado.Test,这让这个测试成为一个所谓的工具测试。

import time

from avocado import Test

class SleepTest(Test):

    def test(self):
        sleep_length = self.params.get('sleep_length', default=1)
        self.log.debug("Sleeping for %.2f seconds", sleep_length)
        time.sleep(sleep_length)

What is an Avocado Test
As can be seen in the example above, an Avocado test is a method that starts with test in a class that inherits from avocado.Test.

however,UTS test don’t inherits from avocado, it inherits from unittest,but there always are similar.

Since an Avocado test inherits from unittest.TestCase, you can use all the assertion methods that its parent.
assertEqual()
assertNotEqual()
assertTrue()
