Automatic testing device and method for cloud printer

Abstract

The invention discloses an automatic testing device for a cloud printer. The automatic testing device comprises the cloud printer, a winding drum connected with the cloud printer through printing paper, a motor connected with the winding drum and a relay used for controlling the motor. An AI camera with a pickup microphone is arranged over the printing paper, the cloud printer and the relay are connected with an upper computer (computer) through serial port lines, and the upper computer is connected with a mobile device terminal (provided with an APP matched with the cloud printer) through a serial port line. The cloud printer end is controlled by an MQTT instruction sent by the upper computer end and an instruction sent by the mobile device end APP, and is used for printing and broadcasting related content and transmitting a real-time local log back to the upper computer through a serial port line. According to the device and the method, automatic testing from instruction issuing to response result judgment and automatic generation of the test report can be completed in batches under the unmanned condition, and objective requirements of batch deployment of cloud printer testing ina short time can be met.

Description

technical field [0001] The invention relates to the technical field of cloud printing, in particular to a cloud printer automatic testing device and a method thereof. Background technique [0002] 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...

Problems solved by technology

[0004] The testing method of cloud printers has not yet formed a mature system. The 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 automated testing, the interface test and end-to-end test cannot be integrated due to the limitation of the result judgment link. Generally speaking, the cloud printer test is still in a fully manual or semi-automatic testing 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 human input
