java - Testing controllers using Spring, JUNIT, MockMvc and Hamcrest -

i trying test controller of mine returns me list of objects on method populate dropdown on page.

i trying write junit test using mockmvc , hamcrest test same.

i want compare list of objects , test if fails or not.

i have created static list of objects in test.java , getting list of objects model.attribute method.

to test: if both list of objects equal , don't contain other objects.

my object called option has 3 properties. key, value , selected. have check if keys exists in list or not.

i unable create matcher same. trying create matcher compare list.

so far have done following:

@before public void setup() throws exception {     // build mockmvc following controller     this.mockmvc = mockmvcbuilders.standalonesetup(openaccountcontroller)             .build(); }  @test public void testopenaccount() {     try {         setalllegislations();         this.mockmvc                 .perform(get("/open_account.htm"))                 // method used print out actual httprequest                 // , httpresponse on console.                 .anddo(print())                 // checking if status 200                 .andexpect(status().isok())                 .andexpect(                         model().attributeexists("appformaccountplans",                                 "appformliralegislations",                                 "appformlrsplegislations",                                 "appformrlsplegislations"))                 .andexpect(                         model().attribute("appformaccountplans", hassize(5)))                 .andexpect(                         model().attribute("appformliralegislations",                                 hassize(8)))                 .andexpect(                         model().attribute("appformlrsplegislations",                                 hassize(2)))                 .andexpect(                         model().attribute("appformrlsplegislations",                                 hassize(1)))                 .andexpect(                         model().attribute(                                 "appformliralegislations",                                 haskeyfeaturematcher(getliralegislations(alllegislations))));   private matcher<list<option>> haskeyfeaturematcher(         final list<option> expectedoptions) {     return new featurematcher<list<option>, list<option>>(             equalto(expectedoptions), "options are", "was") {          @override         protected list<option> featurevalueof(list<option> actualoptions) {             boolean flag = false;             if (actualoptions.size() == expectedoptions.size()) {                 (option expectedoption : expectedoptions) {                     (option actualoption : actualoptions) {                         if (expectedoption.getkey().equals(                                 actualoption.getkey())) {                             flag = true;                         } else {                             flag = false;                             break;                         }                     }                 }             }             if (flag)                 return actualoptions;             else                 return null;         }     }; }  private list<option> getliralegislations(list<option> legislation) {      list<option> liralegislations = new arraylist<option>();     iterator<option> iterator = legislation.iterator();     while (iterator.hasnext()) {         option option = iterator.next();         if (lira_legislations.contains(option.getkey())) {             liralegislations.add(option);         }     }     return liralegislations; }  private list<option> alllegislations;  public list<option> getalllegislations() {     return alllegislations; }  public void setalllegislations() {     alllegislations = new arraylist<option>();     (string key : all_legislations) {         option option = new option();         option.setkey(key);         alllegislations.add(option);     } }  private static final set<string> all_legislations = new hashset<string>(         arrays.aslist(accountlegislationenum.ab.tostring(),                 accountlegislationenum.mb.tostring(),                 accountlegislationenum.nb.tostring(),                 accountlegislationenum.nl.tostring(),                 accountlegislationenum.ns.tostring(),                 accountlegislationenum.on.tostring(),                 accountlegislationenum.qc.tostring(),                 accountlegislationenum.sk.tostring(),                 accountlegislationenum.bc.tostring(),                 accountlegislationenum.fe.tostring(),                 accountlegislationenum.nt.tostring(),                 accountlegislationenum.pe.tostring(),                 accountlegislationenum.yt.tostring(),                 accountlegislationenum.nu.tostring(),                 accountlegislationenum.unknown.tostring())); 

this how getting model attribute as:

 attribute = appformliralegislations            value = [com.abc.arch.core.gui.eform.gui.option@199d1739, com.abc.arch.core.gui.eform.gui.option@185fac52, com.abc.arch.core.gui.eform.gui.option@312a47fe, com.abc.arch.core.gui.eform.gui.option@4edc8de9, com.abc.arch.core.gui.eform.gui.option@71e8e471, com.abc.arch.core.gui.eform.gui.option@70edf123, com.abc.arch.core.gui.eform.gui.option@15726ac1, com.abc.arch.core.gui.eform.gui.option@abeafe7] 

thanks in advance.

you can make life easier when correctly implement option object hashcode() , equals() methods using key attribute; can write:

model().attribute("appformliralegislations",getliralegislations(alllegislations))) 

and rely on list1.equals(list2) method work you.

option hashcode , equals implementation:

public class option {      private string key;     private string label;      ...      @override     public int hashcode() {         final int prime = 31;         int result = 1;         result = prime * result + ((key == null) ? 0 : key.hashcode());         return result;     }      @override     public boolean equals(object obj) {         if (this == obj)             return true;         if (obj == null)             return false;         if (getclass() != obj.getclass())             return false;         option other = (option) obj;         if (key == null) {             if (other.key != null)                 return false;         } else if (!key.equals(other.key))             return false;         return true;     } 

}

methods above generated ide. don't know structure of option class, add label property example in addition key property.
