PyUnit 中是否弃用了测试套件? [英] Is test suite deprecated in PyUnit?

问题描述

按照 PyUnit 中的示例，我想出了以下运行良好的单元测试代码.

Following the example in PyUnit, I came up with the following unittest code that works fine.

import unittest

class Board:
  def __init__(self, x, y):
    self.x = x; self.y = y;
  def __eq__(self, other):
      return self.x == other.x and self.y == other.y

class BoardTest(unittest.TestCase):
    def setUp(self):
        self.b10_10 = Board(10,10)
        self.b10_10p = Board(10,10)
        self.b10_20 = Board(10,20)
    def tearDown(self):
        pass
    def test1(self):
        self.assert_(self.b10_10 == self.b10_10p)
    def test2(self):
        self.assert_(not (self.b10_10 == self.b10_20))

class BoardTest2(unittest.TestCase):
    def setUp(self):
        self.b10_10 = Board(10,10)
        self.b10_10p = Board(10,10)
        self.b10_20 = Board(10,20)
    def tearDown(self):
        pass
    def test1(self):
        self.assert_(self.b10_10 == self.b10_10p)
    def test2(self):
        self.assert_(not (self.b10_10 == self.b10_20))

def suite():
    suite1 = unittest.makeSuite(BoardTest)
    suite2 = unittest.makeSuite(BoardTest2)
    return unittest.TestSuite((suite1, suite2))

if __name__ == "__main__":
  unittest.main()

但问题是，即使我删除了

But the thing is that even if I remove the

def suite():

，结果也是一样的.换句话说，看起来夹具/套件对 PyUnit 来说不是无用的.

, the result is the same. In other words, it looks like that the fixture/suite is not useless with PyUnit.

这是正确的吗?

推荐答案

unittest.TestSuite 如果您想在单个模块中运行所有测试，则不需要，因为 unittest.main() 将动态检查从中调用它的模块并找到所有派生自 unittest.TestCase 的类

unittest.TestSuite is not necessary if you want to run all the tests in a single module as unittest.main() will dynamically examine the module it is called from and find all classes that derive from unittest.TestCase

然而，TestSuite 类在许多情况下仍然很方便:

However, the TestSuite class is still handy in a number of scenarios:

1. 您想要构建一组逻辑测试分组.例如，一套单元测试、集成测试、特定子系统的测试等.
2. 您的测试跨越多个模块/包.在这种情况下，让您可以运行的单个脚本执行所有测试很有用.这可以通过构建一套所有测试来实现.请注意，这与诸如 discovery 之类的库无关.

1. You want to build a set of logical groupings of tests. For instance, a suite of unit tests, integration tests, tests for a specific subsystem, etc.
2. You tests span multiple modules/packages. In this scenario, it is useful to have a single script you can run execute all your tests. This can be accomplished by building up a suite of all your tests. Note that this becomes irrelevant with libraries such as discovery.
