如何在Python鼻子测试中控制函数执行的顺序

Question

In a scenario of Nose tests in python

class test_class(testcase):
   def test_a(self):
      print 'test1'
   def test_b(self):
      print 'test2'
   def test_c(self):
      print 'test3'

when i execute the nosetest, the sequence of execution keep changing. Could some one please advise on how to provide/define a sequence for this execution.

Thanks so much in advance..

Answer 1

That is by design. Nose will run the tests in random order each time and makes no guarantees of the order they will run in. You can provide a setup method that will run before all tests in that class, and a teardown method that will run after all tests in that class.

The idea is to test each thing in a system in isolation, and not have results from previous tests affect other tests. If you need the tests to be ordered, then it's a sign that you need to refactor your tests.
