本文详细探讨了Pyunit测试套件(testsuite)执行过程中的时间计算，以及runner和result模块如何展示测试结果。通过分析源码，理解测试执行后的关键信息输出。

接上文，test case/suit执行完毕，

回到runner.py

计算运行时间， timeTaken = stopTime - startTime

            try:
                test(result)
            finally:
                stopTestRun = getattr(result, 'stopTestRun', None)
                if stopTestRun is not None:
                    stopTestRun()
            stopTime = time.time()
        timeTaken = stopTime - startTime
        result.printErrors()
        ................

打印错误信息：result.printErrors()

    def printErrors(self):
        if self.dots or self.showAll:
            self.stream.writeln()
        self.printErrorList('ERROR', self.errors)
        self.printErrorList('FAIL', self.failures)

    def printErrorList(self, flavour, errors):
        for test, err in errors:
            self.stream.writeln(self.separator1)
            self.stream.writeln("%s: %s" % (flavour,self.getDescription(test)))
            self.stream.writeln(self.separator2)
            self.stream.writeln("%s" % err)

第一篇里面的：

======================================================================  
FAIL: testsum (__main__.MyTest)  
----------------------------------------------------------------------

对应下面的

            self.stream.writeln(self.separator1)
            self.stream.writeln("%s: %s" % (flavour,self.getDescription(test)))
            self.stream.writeln(self.separator2)

还有：

Traceback (most recent call last):  
  File "D:\hy\ws\Prj_jd\pkg_jd\utamy.py", line 13, in testsum  
    self.assertEqual(self.myclassa.addMy(a, b), a * b)  
AssertionError: 9 != 20

对应下面的

            self.stream.writeln("%s" % err)

还有：

----------------------------------------------------------------------
Ran 2 tests in 0.016s

对应下面的：

        if hasattr(result, 'separator2'):
            self.stream.writeln(result.separator2)
        run = result.testsRun
        self.stream.writeln("Ran %d test%s in %.3fs" %
                            (run, run != 1 and "s" or "", timeTaken))
        self.stream.writeln()

还有：

FAILED (failures=1)

对应下面的

        infos = []
        if not result.wasSuccessful():
            self.stream.write("FAILED")
            failed, errored = len(result.failures), len(result.errors)
            if failed:
                infos.append("failures=%d" % failed)
            if errored:
                infos.append("errors=%d" % errored)
        else:
            self.stream.write("OK")
        if skipped:
            infos.append("skipped=%d" % skipped)
        if expectedFails:
            infos.append("expected failures=%d" % expectedFails)
        if unexpectedSuccesses:
            infos.append("unexpected successes=%d" % unexpectedSuccesses)
        if infos:
            self.stream.writeln(" (%s)" % (", ".join(infos),))
        else:
            self.stream.write("\n")
