Weather.feature:
Feature:Checkif the weatherservice worksproperly
In orderto check the weatherservice
As beginner
I'll get some valuesandcheckif theyare okand if the temperature giveniscorrect
Scenario:Checkif a cityand a countrygivenare correct
GivenI accessthe url withhttp://api.openweathermap.org/data/2.5/weather
Andthe cityis Londonandthe countryGB
WhenI ask for the cityand country name
ThenI check if the city andcountry are correct
AndI checkif the status code is200
Scenario:Checkif a latitude andlongitudegivenare correct
GivenI accessthe url withhttp://api.openweathermap.org/data/2.5/weather
Andthe latitude is35 and the longitude 139
WhenI ask for the latitude andlongitude
ThenI check if the latitude andlongitude are correct
AndI checkif the status code is200
Scenario:Checkif the temperature iscorrectgivenacity anda country
GivenI accessthe url withhttp://api.openweathermap.org/data/2.5/weather
Andthe cityis Madridand the country ES
WhenI ask for the cityand country name
ThenI get the temperature lookbycityandcountry
Scenario:Checkif the temperature iscorrectgiventhe latitude andlongitude
GivenI accessthe url withhttp://api.openweathermap.org/data/2.5/weather
Andthe latitude is35 and the longitude 139
WhenI ask for weatherinformationbylatitudeandlongitude
ThenI get the temperature lookbylatitude andlongitude
