Junit testing Struts2 action with Spring -

-

i want test struts action facing following problem:

severe:   [09:16.218] error building bean

it seems spring not dependency injection. indeed, if create default constructor npe because service not instantiated. unit test extend strutsspringtestcase, why action not instanciate correctly ?

here action :

public controllerauthentification(ldapuserservice service) {     this.ldapuserservice = service; }  public string connection() {     if (userldap != null) {         ldapuserservice.save(userldap);         addactionmessage(gettext("success.connect"));         return success;     }     return input; }

unit test :

public class controllerauthentificationtest extends strutsspringtestcase {      public void testconnection() throws exception {          request.setparameter("userldap.login", "login");         request.setparameter("userldap.password", "password");         proxy = getactionproxy("/connection");         controllerauthentification action = (controllerauthentification) proxy.getaction();         string result = proxy.execute();         asserttrue("it true", result.equals(action.success));     } }

applicationcontext

<bean id="ldapuserservice" class="sword.plateformetest.service.impl.ldapuserserviceimpl" /> <bean id="ldapuserauthaction" scope="prototype"     class="sword.plateformetest.action.controllerauthentification">     <constructor-arg ref="ldapuserservice" /> </bean>

and web.xml

<listener>     <listener-class>org.springframework.web.context.contextloaderlistener</listener-class> </listener>  <filter>     <filter-name>struts2</filter-name>     <filter-class>org.apache.struts2.dispatcher.ng.filter.strutsprepareandexecutefilter</filter-class> </filter>  <filter-mapping>     <filter-name>struts2</filter-name>     <url-pattern>/*</url-pattern> </filter-mapping>

stack trace : 

severe:   [56:08.596] error building bean 2013-08-26 13:56:08,600 error sword.plateformetest.action.controllerauthentificationtest.testconnection:37 - error unable intantiate action!     @ com.opensymphony.xwork2.defaultactioninvocation.createaction(defaultactioninvocation.java:299)     @ com.opensymphony.xwork2.defaultactioninvocation.init(defaultactioninvocation.java:397)     @ com.opensymphony.xwork2.defaultactionproxy.prepare(defaultactionproxy.java:194)     @ org.apache.struts2.impl.strutsactionproxy.prepare(strutsactionproxy.java:63)     @ org.apache.struts2.impl.strutsactionproxyfactory.createactionproxy(strutsactionproxyfactory.java:39)     @ com.opensymphony.xwork2.defaultactionproxyfactory.createactionproxy(defaultactionproxyfactory.java:58)     @ org.apache.struts2.strutstestcase.getactionproxy(strutstestcase.java:137)     @ sword.plateformetest.action.controllerauthentificationtest.testconnection(controllerauthentificationtest.java:34)

you should extended strutsspringjunit4testcase instead. here's answer it:

how test struts2 action in junit 4 way?

you might have add struts2-junit-plugin dependency.

as @kevin rave, might have add ".do" end of uri. having exact same issue , appending resolved it.

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
