The execution flow is mainly the same in %% both cases, but with a remote target the test cases are (obviously) %% executed on the target machine. Host and target communicates over %% socket connections because the host should not be introduced as an %% additional node in the distributed erlang system in which the test %% cases are run. %% %% %% Local Target: %% ============= %% %% ----- %% | | test_server_ctrl ({global,test_server}) %% ----- (test_server_ctrl.erl) %% | %% | %% ----- %% | | JobProc %% ----- (test_server_ctrl.erl and test_server.erl) %% | %% | %% ----- %% | | CaseProc %% ----- (test_server.erl) %% %% %% %% test_server_ctrl is the main process in the system. It is a registered %% process, and it will always be alive when testing is ongoing. %% test_server_ctrl initiates testing and monitors JobProc(s). %% %% When target is local, and Test Server is *not* being used by a framework %% application (where it might cause duplicate name problems in a distributed %% test environment), the process is globally registered as 'test_server' %% to be able to simulate the {global,test_server} process on a remote target. %% %% JobProc is spawned for each 'job' added to the test_server_ctrl. %% A job can mean one test case, one test suite or one spec. %% JobProc creates and writes logs and presents results from testing. %% JobProc is the group leader for CaseProc. %% %% CaseProc is spawned for each test case. It runs the test case and %% sends results and any other information to its group leader - JobProc. %% %% %% %% Remote Target: %% ============== %% %% HOST TARGET %% %% ----- MainSock ----- %% test_server_ctrl | |- - - - - - -| | {global,test_server} %% (test_server_ctrl.erl) ----- ----- (test_server.erl) %% | | %% | | %% ----- JobSock ----- %% JobProcH | |- - - - - - -| | JobProcT %% (test_server_ctrl.erl) ----- ----- (test_server.erl) %% | %% | %% ----- %% | | CaseProc %% ----- (test_server.erl) %% %% %% %% %% A separate test_server process only exists when target is remote. It %% is then the main process on target. It is started when test_server_ctrl %% is started, and a socket connection is established between %% test_server_ctrl and test_server. The following information can be sent %% over MainSock: %% %% HOST TARGET %% -> {target_info, TargetInfo} (during initiation) %% <- {job_proc_killed,Name,Reason} (if a JobProcT dies unexpectedly) %% -> {job,Port,Name} (to start a new JobProcT) %% %% %% When target is remote, JobProc is split into to processes: JobProcH %% executing on Host and JobProcT executing on Target. (The two processes %% execute the same code as JobProc does when target is local.) JobProcH %% and JobProcT communicates over a socket connection.

It could also be a nested conf case that gets skipped %% because of a failed or skipped top level conf. %% %% {auto_skip_case,{Case,Comment},Mode} This is a normal test case which %% gets automatically skipped because of a failing init conf case or %% because of a failing previous test case in a sequence. %% %% ------------------------------------------------------------------- %% Description of IO handling during execution of parallel test cases: %% ------------------------------------------------------------------- %% %% A conf group can have an associated list of properties. If the %% parallel property is specified for a group, it means the test cases %% should be spawned and run in parallel rather than called sequentially %% (which is always the default mode). Test cases that execute in parallel %% also write to their respective minor log files in parallel. Printouts %% to common log files, such as the summary html file and the major log %% file on text format, still have to be processed sequentially. For this %% reason, the Mode argument specifies if a parallel group is currently %% being executed. %% %% A parallel test case process will always set the dictionary value %% 'test_server_common_io_handler' to the pid of the main (starting) %% process. With this value set, the print/3 function will send print %% messages to the main process instead of writing the data to file %% (only true for printouts to common log files). %% %% If a conf group nested under a parallel group in the test %% specification should be started, the 'test_server_common_io_handler' %% value gets set also on the main process. This causes all printouts %% to common files - both from parallel test cases and from cases %% executed by the main process - to all end up as messages in the %% inbox of the main process. %% %% During execution of a parallel group (or of a group nested under a %% parallel group), *any* new test case being started gets registered %% in a list saved in the dictionary with 'test_server_queued_io' as key. %% When the top level parallel group is finished (only then can we be %% sure all parallel test cases have finished and "reported in"), the %% list of test cases is traversed in order and printout messages from %% each process - including the main process - are handled in turn. See %% handle_test_case_io_and_status/0 for details. %% %% To be able to handle nested conf groups with different properties, %% the Mode argument specifies a list of {Ref,Properties} tuples. %% The head of the Mode list at any given time identifies the group %% currently being processed. The tail of the list identifies groups %% on higher level. %% %% ------------------------------------------------------------------- %% Notes on parallel execution of test cases %% ------------------------------------------------------------------- %% %% A group nested under a parallel group will start executing in %% parallel with previous (parallel) test cases (no matter what %% properties the nested group has). Test cases are however never %% executed in parallel with the start or end conf case of the same %% group! Because of this, the test_server_ctrl loop waits at %% the end conf of a group for all parallel cases to finish %% before the end conf case actually executes.
