Fitnesse – 2. časť – testovanie webových služieb

172

 F_1

Článok je venovaný použitiu vlastných fixtures do Fitnesse testovacieho frameworku. V tomto článku otestujeme verejne dostupné, takpovediac, edukačné webové služby.

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

  1. Download FitNesse build-u “fitnesse-standalone.jar”
  2. Spustiť ako administrátor: java -jar fitnesse-standalone.jar -p 2222F_2
  3. 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.

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;
	}
}

		try {
			wsdlURL = new URL(url);
		} catch (MalformedURLException e) {
			e.printStackTrace();

		QName SERVICE_NAME = new QName(nameSpace, serviceName);
		CurrencyConvertor ss = new CurrencyConvertor(wsdlURL, SERVICE_NAME);
		CurrencyConvertorSoap port = ss.getCurrencyConvertorSoap();
