Data testing method and device

The invention provides a data testing method and device, and the method comprises the steps: determining a first statistical value of total target type data in a target data set under a preset type according to the target testing data set obtained in a target data processing flow; extracting a preset number of target type data from the target test data set; determining a second statistical value of the extracted target type data under the preset type; and determining whether a data processing result of the target data processing flow is correct or not according to the first statistical value and the second statistical value. Compared with the prior art, the test result can be more accurate, the method and device doe not depend on professional knowledge of business personnel, the method anddevice can be applied to testing of various data, and the universality is high. 本申请提供了一种数据测试方法及装置，针对目标数据处理流程得到的目标测试数据集，确定目标数据集中全量目标类型数据在预设类型下的第一统计值；从所述目标测试数据集中，抽取预设数量的目标类型数据；确定所述抽取的目标类型数据在所述预设类型下的第二统计值；根据所述第一统计值和所述第二统计值，确定所述
