EMI_Test_Report_ARC-Clients_EMI1_RC1.pdf


Component Description

The ARC-Clients components consist of a set of commands necessary for job management, proxy manipulation and data handling. Also, the underlying libraries are included. The compute cli support different job description languages (XRSL, JSDL, JDL), different CE flavours (Classic ARC, A-REX, gLite Cream CE). The data cli handles different storage elements. The arcproxy serves as a general purpose proxy manipulation utility.

The most detailed documentation about ngtest (or arctest) is the man page itself. Even the outdated manuals or the usage (--help) output of the commands contain just a subset of the description of features. Since the role of a functional test is to prove that the software is able to provide the documented features and do it under any circumstances, the base of this test will be the man page and the documented capabilities.

To localize the possible weaknesses it worth to distinguish the features and test them separated from each other. So the following test cases will follow this approach by testing them separately.

ngtest

Documentation errors: [#2303]

  • Referenced man entry doesn't exist: "No entry for arc.conf in section 5 of the manual"
  • -O, -resources stands in the place of -O, -configuration
  • "print this help" stay in the man page which is not THAT help that is referenced

Other errors:

  • When option parsing fails "Invalid options given to arctest" will be printed while executing ngtest (not arctest). [#2304]
Binary usage

Using ngtest [options]: Passed

Using arccli test [options]: Failed Output was: "arccli: command not found" [#2303]

certificates
