前段时间研究PyTest框架时，因为PyTest是可以支持Unittest 和 Nose, 也去研究了Unittest和Nose这两个框架。整理记录以便后续查看。
因为给同事做培训都是用的英文资料，所有文章中大部分会引用英文。
General introduction of unittest
1. Python’s default unittest framework
First unit test framework to be included in Python standard library;
Easy to use by people familiar with the xUnit frameworks;
Strong support for test organization and reuse via test suites.
备注： 默认情况下， Unittest是按照字母顺序执行Test case， 当然可以在TestSuite加载Test Case是组织好顺序
2. Keywords
TestCase: The individual unit of testing.
TestSuite: A collection of test cases, test suites, or both. It is used to aggregate tests that should be executed together.
TestLoader: Load the test cases to the test suite.
TestRunner: A component which orchestrates the execution of tests and provides the outcome to the user.
TestFixture: Represents the preparation needed to perform one or more tests, and any associate cleanup actions. setUp(), tearDown(), setUpClass(), tearDownClass()
Decorator: skip, skipIf, skipUnless, expectedFailure
3. Unittest framework
4. Assert methods
5. Command line
python -m unittest xxx
python -m unittest -h
python -m unittest discover # discovery the test cases(test*.py) and execute automatically
6. Demo
# unittest_tryout/test_unittest_demo1.py

'''
执行unittest：
python test_unittest_demo1.py
结果类似如下：
备注：
1. Discover test cases from folder（python -m unittest discover -s unittest_tryout -v）
2. HTMLTestRunner execute the test cases （python unittest_tryout/test_unittest_demo1.py）
