so current situation such. have build app , running tests on controller. tests hit actual 3rd party api , jackson binding on result map in pojo objects.
i kind of unsure how mock whole thing without me ending population pojo manually . looking take mock json response , bind pojo , can verify matches data on mock json.
here sample of third part calling api
/** * makes api call , stores result in pojo * should gracefully handle errors * @return */ public 3rdpartysearchresult searchapicall(){ if(productquery==null||productquery.isempty() || productquery.trim().isempty()){ throw new nullpointerexception("query string cannot empty"); } resttemplate resttemplate = new resttemplate(); walmartsearchresult wsr = resttemplate.getforobject(3rdpartyapidetails.searchurl, 3rdpartypojo.class,3rdpartyapidetails.apikey,productquery); return wsr; } ii somehow need mock resttemplate.getforobject point mock json file.
the following example test shows 1 way it, using jmockit mocking library:
@test public void exampletestforsearchapicall(@mocked resttemplate rest) { searchapi searchapi = new searchapi(...productquery...); 3rdpartysearchresult result = searchapi.searchapicall(); assertnotnull(result); // verify expected call resttemplate: new verifications() {{ rest.getforobject(...argument values and/or matchers...); }}; }
