java - How to create non-transactional JUnit integration tests in Spring? -

-

an integration test class annotated with:

@runwith(springjunit4classrunner.class) @contextconfiguration(classes = integrationtestconfig.class)

it's not supposed run in transaction isn't marked @transactional i'm getting errors when trying perform persist, merge etc. operations on entitymanager, injected using @persistencecontext:

no transactional entitymanager available

how can resolved?

edit: requested in comments, spring version 4.1.0.release , integrationtestconfig below:

@enableaspectjautoproxy @enableasync @enablescheduling @enabletransactionmanagement @configuration public class integrationtestconfig {     /**      * override existing jpa data source bean test data source.      * @return test data source      */     @bean     public datasource datasource() {         final simpledriverdatasource datasource = new simpledriverdatasource();         datasource.setdriverclass(org.h2.driver.class);         datasource.seturl("jdbc:h2:mem:test;mode=mysql;db_close_delay=-1;db_close_on_exit=false;init=create schema if not exists mydb");         datasource.setusername("sa");         datasource.setpassword("");         return datasource;     } }

if sure never going call entitymanager.flush(), obtain persistencecontext follows:

@persistencecontext(type = persistencecontexttype.extended) private entitymanager entitymanager;

why needed? spring data jpa hands out called shared entitymanager when @persistencecontext annotation used (without attributes). full details available in javadocs org.springframework.orm.jpa.sharedentitymanagercreator. class maintains lookup table entitymanager methods flush, merge, persist, refresh , remove required run inside transaction. so, time encounters method call not inside transaction, bails out.

the annotation @persistencecontext has type attribute can set 1 of persistencecontexttype.extended or persistencecontexttype.transaction, later being default. therefore, default @persistencecontext causes sharedentitymanagercreator transaction , bail out if none found.

using persistencecontexttype.extended bypasses need check transaction when obtaining entitymanager , therefore code should work.

flush still cannot called without transaction because jpa providers require called within transactional context.

c# - Where does the .ToList() go in LINQ query result -

when getting data populate data grid, have pulled data, made list , mapped model, this: public list<person> getpeople() { var data = _db.person.tolist(); list<person> people = new list<person>(); foreach (var item in data) { person person = new person() { personid = item.personid, firstname = item.firstname, lastname = item.lastname }; people.add(person); } return people; } this works fine, in interest of writing less code discovered .select method , (what think is) anonymous type. have: public list<person> getpeople() { return _db.person.select(d => new person { personid = item.personid, firstname = item.firstname, lastname = item.lastname }).tolist(); } though not easy read, works fine too. there preference either way? ...

Listeners to visualise results of load test in JMeter -

i want run load test in non-gui mode , save results in .csv file. (i have not modified .properties files, standard information saved) i plan load file , visualise results jmeter’s listeners. which listeners suited purpose? should avoid @ cost, might cause me misinterpret information? (e.g. in view results tree response data empty have - - not saved this. however, there has in fact been response. if saw listener might think there hasn’t been one. since want avoid this, listeners have gain information needed .csv file.) i’d know both jmeter listeners plugins. if running test in non-ui mode ideally should disable listeners in script. use '-l' option store test results .jtl extension. can later open jtl file jmeter. aggregate report or summary report should summarize test results , response time , throughput. if want plot graphs see trends on test duration can use http://jmeter-plugins.org/#/ standard , lib set. i suggest following listeners: response ...

i using new android support design view collapsingtoolbarlayout. have need position expandedtitle programmatically. actually way set position expandedtitle in .xml file (example here: https://goo.gl/l5h5fc ) there no public api set text position programmatically , fields private . do know if it's possible without reflection or 'hacky' tricks? i have solved problem exposing properties via reflection ( https://gist.github.com/fpezzato/8e7d45112883dbbc5ffb ), works don't use trick in production code. @google: please no more private or final stuff! :)
