unit testing - mocking generic method using Mockito and Scala -

i'm trying write test following function in finatra httpclient.

def executejson[t: manifest](     request: request,     expectedstatus: status = status.ok): future[t] = {...} 

according question answered on stackoverflow. mocking generic scala method in mockito. shorthand for:

def executejson[t](     request: request,      expectedstatus: status = status.ok)     (implicit t: manifest[t]): futuren[t] = {...} 

so tried,

verify(httpclientmock, times(1)).executejson[jiraproject]     (argthat(new requestmatcher(req)))(matchers.any()) 

unfortunately, didn't solve problem. still got following error.

invalid use of argument matchers! 0 matchers expected, 1 recorded: -> @ org.specs.mock.mockitostubs$class.argthat(mockito.scala:331)  exception may occur if matchers combined raw values: //incorrect: somemethod(anyobject(), "raw string"); when using matchers, arguments have provided matchers. example: //correct: somemethod(anyobject(), eq("string matcher")); 

i tried matchers.eq(manifest[jiraproject]), complains value manifest of type scala.reflect.manifestfactory.type not take type parameters.

i'm new scala , mockito, there did wrong or misunderstood?

thanks in advance help!

found out problem! executejson takes 3 params- request, expectedstatus, , manifest. however, because expectedstatus optional, didn't explicit pass it, that's why complained. so, final code should verify(httpclientmock, times(1)).executejson[jiraproject](argthat(new requestmatcher(req)), matchers.any[status])(matchers.any())

your problem you're using equality in first parameter , matcher second one. try using matchers arguments.

but bigger problem feel here you're trying mock 3rd party library - this should avoid. solve problem. here's read - enter link description here
