Abstract: According to some embodiments, systems and methods are provided including an automatic testing (AT) framework including an automatic testing (AT) tool and an AT engine; a processing unit coupled to the automatic testing framework to: generate a JSON file, wherein the JSON file is a test case; upload the generated test case to a database of the AT framework; and execute the test case in response to uploading, wherein execution further comprises: reading the test case from the database; validating the JSON file matches a JSON schema; mocking the test case to generate an executable test, including one or more nullable values based on the generated JSON file; executing the executable test to generate an output; and verifying the generated output by comparing the generated output to an expected output in the test case. Numerous other aspects are provided.

Abstract: A portable electric car washer is mainly formed by a soft water bag (1), a change valve (2), a belt wheel outer box, an electronic water pump, a water gun, and a water discharging pipe (5). The soft water bag (1), the water discharging pipe (5) and water feeding and discharging openings of the water pump are all connected to the change valve (2). The switching of the change valve (2) can make water pass through the water discharging pipe (5), is filled into the water bag (1) or ejected out of the water bag (1). After all water is discharged from the soft water bag (1), the soft water bag (1) can be placed in the belt wheel outer box. The belt wheel outer box is provided with a castor to movably support the soft water bag (1). The belt wheel outer box is mainly formed by a box body (3) and a cover plate (4). The castor is mounted below the cover plate (4), and the cover plate (4) can be taken off and is cushioned and fixed on a bottom of the box body (3) to movably support the box body (3).
