Description

A cloud printer automated testing method

technical field

The present invention relates to the technical field of cloud printing, in particular to an automated testing method for cloud printers.

Background technique

The rise of the Internet of Things and cloud printing technology has brought more and more people's attention to cloud printers. Due to its advantages of not relying on external storage devices and convenient management of printing records, cloud printers have been widely used in campus printing and takeaway printing in recent years. realistic scene. Different from traditional printers, cloud printers are connected to the Internet in a broader sense, which can realize real-time communication with more and larger communication devices, and their communication methods are also different from traditional printers. After the cloud printer is connected to the network, it usually communicates with the upstream server based on MQTT, and executes the instructions issued by the server. At the same time, cloud printers generally have a supporting APP for network configuration and printing parameter settings.

For the testing of cloud printers, the industry currently mostly adopts fully manual or semi-automatic testing methods, that is, through manual/automated scripts to click on the APP or issue MQTT commands, and observe the response results of the cloud printer with the naked eye for testing.

The testing method of cloud printers has not yet formed a mature system. Existing testing methods can be realized through manual/automated scripts in part of the instruction issuing link. However, most of the final identification/judgment links in the end-to-end testing link still rely on manual participation. Therefore, even if the interface test function partially realizes the automated test, the interface test and the end-to-end test cannot be integrated due to the limitation of the judgment of the result. Generally speaking, the test of the cloud printer is still in a fully manual or semi-automatic test stage. When the version is iterated quickly and the test items are complicated, the efficiency of manual test results is low, and it is prone to missed tests and false tests, which will cause hidden dangers to the final test results. On the other hand, the existence of end-to-end manual testing makes it impossible for testers to conduct systematic batch testing in a short period of time, and the statistical analysis of test results is also very dependent on later manpower input.
