Distributed system test device

A system, comprising:

• a processor;
• a computer readable memory in circuit communication with the processor;
• and
• a computer readable storage medium in circuit communication with the processor;
• wherein the processor executes program instructions stored on the computer-readable storage medium via the computer readable memory and thereby:
• instigates execution of a unique hypertext transfer request protocol test case within a distributed system that comprises a plurality of different, networked servers, wherein a header of the unique test case comprises a unique name for the unique test case, and wherein the distributed system servers are each configured to, in response to processing a test case, generate a time-stamped log entry that comprises header data for the processed test case and a uniform resource locator address of the processing server, and to update logged header data with a source of each test case request;
• maps the unique test case to a subset of the distributed system servers as endpoint servers of the unique test case, in response to determining that the uniform resource locator addresses of each of the subset endpoint servers are listed within generated log entries of the endpoint servers in association with the unique test case name;
• and
• determines a sequential call chain for execution of the unique test case by the subset endpoint servers as a function of the header data comprising the unique test case name within logged entries for each of the subset endpoint servers, and by identifying a sequential series of uniform resource locator addresses of the subset endpoint servers within logged entries for subsequent receiving ones of the subset endpoint servers that comprise the unique test case name.

A computer program product for capturing test coverage in a distributed system, the computer program product comprising:

• a computer readable storage medium having computer readable program code embodied therewith, wherein the computer readable storage medium is not a transitory signal per se, the computer readable program code comprising instructions for execution by a processor that cause the processor to:
• instigate execution of a unique hypertext transfer request protocol test case within a distributed system that comprises a plurality of different, networked servers, wherein a header of the unique test case comprises a unique name for the unique test case, and wherein the distributed system servers are each configured to, in response to processing a test case, generate a time-stamped log entry that comprises header data for the processed test case and a uniform resource locator address of the processing server, and to update logged header data with a source of each test case request;
• map the unique test case to a subset of the distributed system servers as endpoint servers of the unique test case, in response to determining that the uniform resource locator addresses of each of the subset endpoint servers are listed within generated log entries of the endpoint servers in association with the unique test case name;
• and
• determine a sequential call chain for execution of the unique test case by the subset endpoint servers as a function of the header data comprising the unique test case name within logged entries for each of the subset endpoint servers, and by identifying a sequential series of uniform resource locator addresses of the subset endpoint servers within logged entries for subsequent receiving ones of the subset endpoint servers that comprise the unique test case name.
