如何在 Behave 框架（Python）断言失败时继续执行 "for" 循环？

Question

@then("----------------------------------")
def step_impl(context, vnf):
        some_list=[] //  list of values
        is_log_exists = False 
        for log in context:
                for key, val in log.items(): 
                        is_log_exists = all(elem in val for elem in some_list) // checking if all the element in  some_list is present in val which is also a list.
        assert is_log_exists, f"Failed"

参考上面一段代码。一旦断言失败而不是停止执行，有没有其他方法可以继续for循环中的下一次迭代？每当发生断言失败时，都应该在控制台中看到它，并且应该开始下一次迭代。

我认为您应该单独跟踪失败，然后创建自定义断言消息以向用户显示错误：

@then("----------------------------------")
def step_impl(context, vnf):
    some_list=[] #  list of values
    failures = list()
    for log in context:
        for key, val in log.items(): 
            for elem in some_list():
                if val not in elem:
                    failures.append((val, elem))

    # Create an assertion message detailing why the assertion failed
    assert_msg = "The following values were not found in the corresponding element:\n"
    for val, elem in failures:
        assert_msg += "Value: {}, Element: {}\n".format(val, elem)

    # This form of the assertion allows you to pass in a custom message that will be
    # displayed only if the assertion is False
    assert len(failures) == 0, assert_msg
