Electronic device, host apparatus, communication system, and recording medium

A host apparatus that communicates, via a network, with an apparatus in which is implemented an electronic device housing a diagnostic circuit, the host apparatus comprising:

• a test information storage section that stores in advance test information indicating test content to be performed by the diagnostic circuit;
• a test information transmitting section that, when the test information is requested by the electronic device, transmits the test information to the electronic device;
• and
• a test information generating section that (i) receives a test result from the diagnostic circuit via the network, (ii) generates the test information indicating the test content to be performed next by the diagnostic circuit, based on the test result, and (iii) stores the test information in the test information storage section, wherein
• the diagnostic circuit performs a test that judges whether the electronic device is operating properly in a test condition corresponding to the test information supplied thereto, and
• the test information generating section causes the diagnostic circuit to perform a margin test that measures a range of the test condition for which the electronic device operates properly by sequentially generating, as the test information to be performed next by the diagnostic circuit, test information in which the test condition changes according to the test result.
