Článok je venovaný použitiu vlastných fixtures do Fitnesse testovacieho frameworku. V tomto článku otestujeme verejne dostupné, takpovediac, edukačné webové služby.
V predchádzajúcom článku som sľúbil, že budeme pokračovať vytvorením fixtures na otestovanie skutočných webovýuch služieb. Konkrétne sa pokúsime otestovať webové služby:
Druhá časť článkov o Fitnesse testovacom frameworku bude obsahovať menej „omáčkových rečí“, ktoré sa dajú vždy nájsť na webe, zato sa však pokúsim pomocou uverejnených zdrojákov ilustrovať použitie tohto nástroja v praxi.
Začíname
- Download FitNesse build-u “fitnesse-standalone.jar”
- Spustiť ako administrátor: java -jar fitnesse-standalone.jar -p 2222
- Na vygenerovanie proxy java tried z WSDL súborov môžete použite váš obľúbený spôsob. Ja som použil Maven, takže mavenovský pom.xml bude obsahovať aj nasledujúce elementy.

Štruktúra Fitnesse projektu
Do adresára wsdl_new pribudnú nami definované wsdl súbory atribútov pom.xml
… a vygenerované proxy triedy na volanie webových služieb do package „generated“
Facade services
Trieda WeatherService pošle webovému servisu požiadavku prostredníctvom ZIP kódu mesta v USA a vráti aktuálnu teplotu vo farenheitoch.
WeatherService.java
package com.rhe.fitnesse.wsFacade;
import generated.WeatherWS.WeatherReturn;
import generated.WeatherWS.WeatherSoap;
import java.util.HashMap;
import java.util.logging.Logger;
public class WeatherService {
public final static Logger LOGGER = Logger.getLogger(ConversionRateService.class.getName());
HashMap<String, Object> hm = new HashMap<String, Object>();
public HashMap<String, Object> doWeather(WeatherSoap wService, String zip) {
long start = System.currentTimeMillis();
WeatherReturn ret = wService.getCityWeatherByZIP(zip);
hm.put("city", ret.getCity());
hm.put("state", ret.getState());
hm.put("farenheit", ret.getTemperature());
System.out.println(zip+" City:"+ret.getCity()+" State:"+ret.getState()+" Temperature:"+ret.getTemperature()+" Farenheit");
long end = System.currentTimeMillis();
long dur = end-start;
LOGGER.info("Operation took " + dur + " ms");
return hm;
}
}
Trieda ConversionRateService pošle webovému servisu požiadavku prostredníctvom meny „From“ a many „To“, pričom vráti aktuálny kurz oboch mien. Napríklad EUR->CZK.
ConversionRateService.java
package com.rhe.fitnesse.wsFacade;
import generated.currencyConvertor.Currency;
import generated.currencyConvertor.CurrencyConvertorSoap;
import java.util.logging.Logger;
public class ConversionRateService {
public final static Logger LOGGER = Logger.getLogger(ConversionRateService.class.getName());
public double doCR(CurrencyConvertorSoap ccService, String from, String to) {
long start = System.currentTimeMillis();
Currency cFrom = Currency.fromValue(from);
Currency cTo = Currency.fromValue(to);
double dd = ccService.conversionRate(cFrom, cTo);
System.out.println("Conversion rate from "+from+" to "+to+" is "+dd);
long end = System.currentTimeMillis();
long dur = end-start;
LOGGER.info("Operation took " + dur + " ms");
return dd;
}
}
Fixtures
obsahujú všetky skripty použiteľné vo Fitness front end.

}
}
CheckWeather.java
