python-unittest module in all kinds of assertions

• Reprinted feeling too lazy to write their own people to write it enough, reproduced easily query their own use
• unittest asserts there are three main types:

• • The basic Boolean assertion that: either right or wrong verification
  • Compare assertion, such as the value comparing two variables (Boolean with the above assertion is not very different, mainly worth a Boolean value by comparing two variables)
  • Complex asserted (generally relatively small, as asserted two lists, tuples etc.)
  • The basic assertion Boolean
  • This parameter is the assertion of right and wrong, of course, there are some relatively assertion. We have one thing in common: there is a msg parameter, if the value of the msg parameter is specified, then the information is returned as an error message failed. Mainly in the following:

 

 

 

 

 

• 　　Compare assertion

 

    　assertAlmostEqual (first, second, places = 7, msg = None, delta = None)

　　Approximately equal to first verify second. palces: Specifies the number of decimal places, the default is 7

 

　　assertNotAlmostEqual (first, second, places, msg, delta)

　　First verification is not approximately equal to second. palces: Specifies the number of decimal places, the default is 7

　　NOTE: In the above-described two functions, if the delta value is specified, then the difference between the first and the second must ≤delta

 

　　assertGreater (first, second, msg = None)

　　Verify first> second, otherwise fail

 

　　assertGreaterEqual (first, second, msg = None)

　　Verify first ≥ second, otherwise fail

 

　　assertLess (first, second, msg = None)

　　Verify first <second, otherwise fail

 

　　assertLessEqual (first, second, msg = None)

　　Verify first ≤ second, otherwise fail

 

　　assertRegexpMatches (text, regexp, msg = None)

　　Verify regular expression regexp search for matching text text. regexp: usually re.search ()

 

　　assertNotRegexpMatches (text, regexp, msg = None)

　　Verify regular expression regexp does not match the search text text. regexp: usually re.search ()

• 　　Complex assertions
