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. +%% +%% The low-level mechanism for buffering IO for the common log files +%% is handled by the test_server_io module. Buffering is turned on by +%% test_server_io:start_transaction/0 and off by calling +%% test_server_io:end_transaction/0. The buffered data for the transaction +%% can printed by calling test_server_io:print_buffered/1. +%% +%% This module is responsible for turning on IO buffering and to later +%% test_server_io:print_buffered/1 to print the data. To help with this, +%% two variables in the process dictionary are used: +%% 'test_server_common_io_handler' and 'test_server_queued_io'. The values +%% are set to as follwing: +%% +%% Value Meaning +%% ----- ------- +%% undefined No parallel test cases running +%% {tc,Pid} Running test cases in a top-level parallel group +%% {Ref,Pid} Running sequential test case inside a parallel group +%% +%% FIXME: The Pid is no longer used. +%% +%% 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. +%% +%% 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 test_server_io:print_buffered/1 +%% can be called for each test case. 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. This has the effect +%% that it's only after a nested group has finished that any +%% remaining parallel cases in the previous group get spawned (*). +%% Example (all parallel cases): +%% +%% group1_init |----> +%% group1_case1 | ---------> +%% group1_case2 | ---------------------------------> +%% group2_init | ----> +%% group2_case1 | ------> +%% group2_case2 | ----------> +%% group2_end | ---> +%% group1_case3 (*)| ----> +%% group1_case4 (*)| --> +%% group1_end | ---> +%% + +run_test_cases_loop([{SkipTag,CaseData={Type,_Ref,_Case,_Comment}}|Cases], + Config, TimetrapData, Mode, Status) when + ((SkipTag==auto_skip_case) or (SkipTag==skip_case)) and + ((Type==conf) or (Type==make)) -> + run_test_cases_loop([{SkipTag,CaseData,Mode}|Cases], + Config, TimetrapData, Mode, Status); + +run_test_cases_loop([{SkipTag,{Type,Ref,Case,Comment},SkipMode}|Cases], + Config, TimetrapData, Mode, Status) when + ((SkipTag==auto_skip_case) or (SkipTag==skip_case)) and + ((Type==conf) or (Type==make)) -> + file:set_cwd(filename:dirname(get(test_server_dir))), + CurrIOHandler = get(test_server_common_io_handler), + ParentMode = tl(Mode), + + {AutoOrUser,ReportTag} = + if SkipTag == auto_skip_case -> {auto,tc_auto_skip}; + SkipTag == skip_case -> {user,tc_user_skip} + end, + + %% check and update the mode for test case execution and io msg handling + case {curr_ref(Mode),check_props(parallel, Mode)} of + {Ref,Ref} -> + case check_props(parallel, ParentMode) of + false -> + %% this is a skipped end conf for a top level parallel + %% group, buffered io can be flushed + handle_test_case_io_and_status(), + set_io_buffering(undefined), + {Mod,Func} = skip_case(AutoOrUser, Ref, 0, Case, Comment, + false, SkipMode), + ConfData = {Mod,{Func,get_name(SkipMode)},Comment}, + test_server_sup:framework_call(report, + [ReportTag,ConfData]), + run_test_cases_loop(Cases, Config, TimetrapData, ParentMode, + delete_status(Ref, Status)); + _ -> + %% this is a skipped end conf for a parallel group nested + %% under a parallel group (io buffering is active) + wait_for_cases(Ref), + {Mod,Func} = skip_case(AutoOrUser, Ref, 0, Case, Comment, + true, SkipMode), + ConfData = {Mod,{Func,get_name(SkipMode)},Comment}, + test_server_sup:framework_call(report, [ReportTag,ConfData]), + case CurrIOHandler of + {Ref,_} -> + %% current_io_handler was set by start conf of this + %% group, so we can unset it now (no more io from main + %% process needs to be buffered) + set_io_buffering(undefined); + _ -> + ok + end, + run_test_cases_loop(Cases, Config, + TimetrapData, ParentMode, + delete_status(Ref, Status)) + end; + {Ref,false} -> + %% this is a skipped end conf for a non-parallel group that's not + %% nested under a parallel group + {Mod,Func} = skip_case(AutoOrUser, Ref, 0, Case, Comment, + false, SkipMode), + ConfData = {Mod,{Func,get_name(SkipMode)},Comment}, + test_server_sup:framework_call(report, [ReportTag,ConfData]), + + %% Check if this group is auto skipped because of error in the + %% init conf.
