is possible have hangfire instantiate objects configure jobactivator when they're scheduled run recurringjob? the signature of method seems force static usages: public static void addorupdate<t>( string recurringjobid, expression<action<t>> methodcall, i have several ideas on how "abuse" statics channel things around, feel might missing something. there design decision hangfire supports statics in chron jobs? quick answer no, default job activator works on parameter-less constructors or static methods. did (in vb.net) quick , dirty see if working , have shown below. by using "addorupdate", telling hangfire create instance of t , access method of t, signature works on instance members, not statics. if use 1 of other "addorupdate" method signatures without generic parameter, require static. now fun part: if type t doesn't have parameter-less default constructor fail using default jobactivator said. t

i worked on java/java ee project , have deliver unit test plan , i've worked on many integration tests plans, describes integration tests scenarios, i've never heard of unit test plan. this unit test plan have describe unit tests i've done, , related rule in specifications. is there such thing in java project life cycle ? if yes, can have example , or how make one . unit tests should self explanatory. they used programmers sure code correct , doesn't affect existing code. any programmer should free add new tests if necessary, maintain document define plan of unit tests strange approach. from point of view, test plan should used define acceptance tests or integration tests, not unit tests. note unit tests useful during programming phase , during programming phase not possible know tests written. possible imagine unit test plan written @ end of work when plan not needed.

i'm restructuring python libraries our company developing various groups. avoid polluting top level module namespace i'd group under top level 'companyname' package, we'll have 'coname.utils', 'coname.qa', 'coname.api', , on. several of these expected distributed our product, or publicly installable. 'qa' purely internal. google similar. e.g., protobuf library available "google.protobuf" in module path. however, it's not particularly clean: .pth file installed protobuf package looks this: import sys, types, os;p = os.path.join(sys._getframe(1).f_locals['sitedir'], *('google',));ie = os.path.exists(os.path.join(p,'__init__.py'));m = not ie , sys.modules.setdefault('google', types.moduletype('google'));mp = (m or []) , m.__dict__.setdefault('__path__',[]);(p not in mp) , mp.append(p) i think fool import engine because there's no __init__.py in "google"
