代码应该返回触发器对象 - 触发器映射的长度应该显示实际存在的触发器的实际数量...如果至少有一个或多个触发器但它们全部返回则应该返回True错误的ZERO触发器......任何人都可以帮忙吗？代码如下，测试人员的错误消息将打印在下面。
def makeTrigger(triggerMap, triggerType, params, name):

triggerfile = open(filename, "r")
all = [ line.rstrip() for line in triggerfile.readlines() ]

continue
lines.append(line)

trigger = makeTrigger(triggerMap, linesplit[1],
linesplit[2:], linesplit[0])

现在这里是来自测试人员的错误消息 - 如果可能的话请帮忙......我的想法都搞糊涂了!!! Total中有一些SEVEN测试可以提供这些错误信息，而且我仍然无法理解如何修复！如果可以的话，请帮帮忙......

答案 0 :(得分：0)
看起来你并没有在makeTrigger函数中执行任何代码;你只是定义了另一个函数readTriggerConfig。
您是否尝试将makeTrigger函数与其余代码隔离开来，并使用一小组已知输入运行它以更好地了解其行为？使用调试器逐步执行它可能有助于您了解正在发生的事情。
