playframework - Play scala integration spec - Injecting dependencies through Guice -

-

i use scala, play 2.4, , slick 3 in project. have following dao code , works fine end end.

@singleton() class companiesdao @inject() (protected val dbconfigprovider: databaseconfigprovider) extends companiescomponent   hasdatabaseconfigprovider[jdbcprofile] {   import driver.api._ }

however, can't working expected in integration test because of dbconfig stuff. integration test below:

class companiesdaointegrationspec extends funspec oneserverpersuite {     def companiesdao(implicit app: application) = {       val app2companiesdao = application.instancecache[companiesdao]       app2companiesdao(app)     }      describe("create") {         it("should create ") {             companiesdao.create...         }     } }

if don't put db properties in application.conf got following error:

[info]   java.lang.runtimeexception: com.google.inject.provisionexception: unable provision, see following errors: [info] [info] 1) no implementation play.api.db.slick.databaseconfigprovider bound. [info]   while locating play.api.db.slick.databaseconfigprovider [info]     parameter 0 @

it seems given above code, play application reads db properties configuration file located @ /conf/application.conf.

my project setup bit different this, have multiple environments have file structuers like:

/conf/local/application.conf /conf/testing/application.conf /conf/staging/application.conf /conf/production/application.conf

when run play application using command like: activator run -dconfig.resource=/conf/local/application.conf , work fine. want same integration spec like: activator test -dconfig.resource=/conf/local/application.conf. play read specified config run integration tests.

what's best way achieve that?

you have make trait , mix in test, , work.

trait withdatabaseconfig {     lazy val (driver, db) = {         val dbconfig = databaseconfigprovider.get[jdbcprofile](play.current)         (dbconfig.driver, dbconfig.db)     } }

i have no idea why, i'm scala beginner. has not/running app or guice. found in samples folder @ https://github.com/playframework/play-slick/blob/1.1.x/samples/json/test/dbspec.scala

-
suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
