1. A computer-implemented method for executing a system application test case of a runtime system in an integrated server environment, the computer-implemented method comprising: establishing, by an integrated server environment, a transmission control protocol connection between a client development environment and the integrated server environment, based on a request, in the client development environment, to initiate execution of the system application test case, the establishing of the transmission control protocol performed in parallel between the client development environment and the integrated server environment; issuing, by the integrated server environment, a data transfer protocol transmission request to the integrated server environment for a description script of the system application test case, the data transfer protocol transmission request being Hypertext Transfer Protocol; transmitting, by the integrated server environment, an extensible markup language of the requested description script to the client development environment, via a server component of the integrated server environment; issuing, by the integrated server environment, a data transfer protocol transmission request to execute the test of system application test case in the integrated server environment, based on the transmitted description script; executing, by the integrated server environment, the system application test case in the integrated server environment, wherein the server component compiles test results of the executed system application test case in an extensible markup language document; and transmitting, by the integrated server environment, the extensible markup language document of the compiled test results to the client development environment for display, the extensible markup language document comprising a plurality of logs identifying a system application test case condition.
