automated tests - Regarding Automation Approach -

-


supposed automate application developed in powerbuilder. in order test application using rational robot functional testing tool. expect @ least 40 -50% of change control in application each release. release trends scheduled @ least 3 times in year.

the product has different setup each client. accordingly scenario has been derived. although if there change occurs, in functional feature , in interface. pointing that, need proceed automation. identified few areas stabilized (i.e., no major changes occurs) automate. feasible proceeding automation?

could please suggest me how go on this?

i've seen answer last question involve consultant spending 2 days interviewing development team, 3 days developing report. and, in cases, i'd report preliminary, introductory, , rushed. however, let me throw out few ideas may manage expectations on team.

testing automation great checking regressions in functionality allegedly isn't being touched. things framework changes or database changes can cause untouched code crash. risk-averse environments (e.g. banking, pharmaceutical prescriptions), investment in automation worth effort.

however, i've seen often underestimation of effort. test functionality in unit (let's window, example), need review specifications, design tests test each functional point, plan data (what data going window, how make sure data expected when start test each time, data when you've finished tests, how ensure data, including non-visible data, correct), script , debug tests. i'm not sure professional testers (i'm developer trade, have taken course in automated testing tool), if aren't planning same amount of effort expended on developing automation tests you're spending on application development same functionality, think you'll become frustrated. add changing functionality means changing testing scripts, , automated testing can become significant cost. (so, tell manager automated testing doesn't mean push button , things tested. < grin > )

that's not can't expend less effort on testing , some results, pay for. having script opens , closes windows in app provides some value, won't tell new behaviour implemented in framework being overridden on window x, or database change has screwed sequencing of items in drop down datawindow, or report completion time goes 5 seconds 5 hours. however, again, don't underestimate effort. new tool new language , idiosyncrasies need figured out , mastered.

automated testing can great investment. if cost of failure significant, badly prescribed drug causing death, investment worth it. however, cases there high turn on of functionality (like think you're describing) , consequences of failure less critical, might want consider comparing cost/benefit of testing automation additional manual testing resources.

good luck,

terry

i trying send mail linux command line using mailx command. can send local domain no problem want set mail send gmail account receive mail sent gmail account. after configuring mail.rc so: account gmail { set smtp=smtps://smtp.gmail.com:587 set smtp-auth=login set smtp-auth-user=username@gmail.com set smtp-auth-password=password set ssl-verify=ignore } i error: resolving host smtp.gmail.com . . . done. connecting 74.125.25.109 . . . connected. missing "nss-config-dir" variable.

c# - Is it possible to remove an existing registration from Autofac container builder? -

-
something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
