assertAlmostEqual() and assertNotAlmostEqual() test whether first and second are approximately equal. This method can either round their difference to an optionally-specified number of places (the default is 7) and compare it to zero, or require the difference to be smaller than a supplied del...

assertEqual(widget.size(), (50, 50)) 可以看到,为了进行测试,我们使用了基类 TestCase 提供的其中一个 assert*() 方法。若测试不通过,将会引发一个带有说明信息的异常,并且 unittest 会将这个测试用例标记为测试不通过。任何其它类型的异常将会被当做错误处理。 可能同时存在多个前置操作相同的测试,我们可以把...
assertEqual(captured, "hello") test.support.disable_faulthandler() A context manager that replaces sys.stderr with sys.__stderr__. test.support.gc_collect() Force as many objects as possible to be collected. This is needed because timely deallocation is not guaranteed by the garbage ...

self.assertEqual(formatted_name, 'Janis Joplin') unittest.main() 断言方法用来核实得到的结果是否与期望的结果一致。 运行结果中,第一行的.表示有一个测试通过了,接下来指出Python运行一个测试消耗的时间,最后的OK表明该测试用例中所有单元测试都通过了。
1def square_fn(x): 2 return x * x 3 4square_ld = lambda x : x * x 5 6for i in range(10): 7 assert square_fn(i) == square_ld(i) lambda 函数可以快速声明,所以拿来当回调 (Callbacks) 函数是非常理想的:就是作为参数 (Arguments) 传递给其他函数用的,那种函数。 和map、filter 和 ...
