Background:
I'm currently writing behat tests (Mink/Selenium) for a Symfony2 webpage. I have a good deal of examples to go by, and actually writing them should be no problem. The step definitions are already written.
However, in the examples, they some times define a Scenario: and some times a Scenario Outline:
What is the difference between these two ways of defining a test?

Copying and pasting scenarios to use different values can quickly become tedious and repetitive:
Scenario: Eat 5 out of 12
Given there are 12 cucumbers
When I eat 5 cucumbers
Then I should have 7 cucumbers
Scenario: Eat 5 out of 20
Given there are 20 cucumbers
When I eat 5 cucumbers
Then I should have 15 cucumbers
Scenario Outlines allow us to more concisely express these examples through the use of a template with placeholders
Scenario Outline: Eating
Given there are &start& cucumbers
When I eat &eat& cucumbers
Then I should have &left& cucumbers
| start | eat | left |
The Scenario Outline steps provide a template which is never directly run. A Scenario Outline is run once for each row in the Examples section beneath it (except for the first header row).

Scenario is what it is.
Scenario outline uses placeholders for faster testing.

I have the following feature:
Feature: Check if the weather service works properly
In order to check the weather service
As beginner
I'll get some values and check if they are ok and if the temperature given is correct
Scenario: Check if a city and and country given are correct
Given I access the url with http://api.openweathermap.org/data/2.5/weather
And the city is &city& and the country &country&
When I ask for the city and country name
Then I check if the city and country are correct
And I check if the status code is 200
| country |
| Barcelona | ES
And I have the following step:
@step("the city is (.*) and the country (.*)")
def city_and_country(self, expectedCity, expectedCountry):
world.expectedCity = expectedCity
world.expectedCountry = expectedCountry
but when I execute this step I have the followin information:
I check the lettuce documentation and the scenario outline looks pretty well, but I still don?t understand what I'm doing wrong. Any ideas?
Thanks in advance!
I just found the answer to my own question:
Scenario Outline: Check if a city and and country given are correct
Given I access the url with http://api.openweathermap.org/data/2.5/weather
And the city is &city& and the country &country&
When I ask for the city and country name
Then I check if the city and country are correct
And I check if the status code is 200
| country |
| Barcelona | ES
And the step definition is:
@step('the city is ([^"]+) and the country ([^"]+)')
def city_and_country(self, expectedCity, expectedCountry):
world.expectedCity = expectedCity
world.expectedCountry = expectedCountry
Hope it helps in a future!

I just starting to work with SpecFlow and really like the tool.
However I am running across some issues in relation to example data inputs into the Scenario Outlines.
Just wondering if what I am facing is normal or whether there is a trick to it.
I am using C# Visual Studio 2013 and writing an MVC App using the underscore style of step definition.
I have also tried the regular expression style but still get similar issues.
So the issue is I am providing username, password etc as parameters and including sample data in my Examples.
It appears that the following occurs: -
I have to put "" around the parameters when 1st generating the scenario, otherwise it does not get picked up as a parameter at all.
However when passing data in from the examples I get a "/" at the end of the data passed in.
When I go back to the scenario I then remove the "" around the parameter.
This is a little frustrating but if that is the best way to handle it I can live with that.
Just wondering if anyone has any advice on this point.
The next issue is related to the data itself.
It appears if I have any characters such as @ or & etc in my data, then it splits that data at that point and feeds it to the next parameter so I get incorrect data being fed through.
I have included my code below - if anyone has any suggestions or resources to look at that would be appreciated.

SpecFlow does handle string parameters by default, the problem is that you left control up to SpecFlow in determining at runtime what your values are.
When you ran "Generate Step Definitions," you selected "Method name - underscores" in the Style dropdown. This left interpreting the input parameters up to SpecFlow, which will create what are called 'greedy' regular expressions to identify the parameter values. This means that it would include the comma as part of the value.
Had you selected "Regular expressions in attributes," (or refactored your code a touch and decorated your attributes by hand) your step could look like this:
[Given(@"I have completed the form with (.*), (.*), (.*), and (.*)")]
public void Given_I_have_completed_the_form_with(string email, string org, string pwd, string conf)
//do stuff here
This creates a more 'parsimonious' expression that tells SpecFlow to accept strings of any length, up to but not including any trailing commas. Single quotes around the regular expressions would make it even more explicit:
[Given(@"I have completed the form with '(.*)', '(.*)', '(.*)', and '(.*)'")]
Managing the regular expressions yourself can create headaches, but it really exposes the full power of SpecFlow if you do so.
RESOLVED - It was not an issue with the use of characters such as @ or &.
It was actually using commas in my Given Statement.
I found if I used 'and' it works.
So to get it working the statement had to be written as below: -
Write statement as
Given I have completed the form with &email& and &organisation& and &password& and &passwordConfirmation&
Modify statement to put single quotes around paramaters that need to be strings
Given I have completed the form with '&email&' and '&organisation&' and '&password&' and '&passwordConfirmation&'
Generation Step Definitions and then change statement back to exclude single quotes
Given I have completed the form with &email& and &organisation& and &password& and &passwordConfirmation&
A bit of mucking around but it gets the correct results.
Hopefully in the future SpecFlow will be updated to handle paramaters as strings as default.

J it only takes a minute:
In the project I am currently working we are using cucumber for integration testing and to keep the regular daily builds from getting too big we use profiles using tags to have a smaller daily test and a larger weekly build test suite.
Now I have a scenario outline with example inputs that I want to split up so that one example is in the daily build and others in the weekly.
Something in the spirit of
Scenario Outline: Doing some tests
Given a step
When I do some &input&
Then I should get some &output&
|daily 2 o |
|week 999 o|
Is this possible in any way? Should it be? Or is it a dumb idea to do it this way?
After some research I found out that this is already supported from out of the box. You just have to add two Example headers to the test. Using my own example from the question to illustrate
Scenario Outline: Doing some tests
Given a step
When I do some &input&
Then I should get some &output&
|daily 2 o |
|week 999 o|
Have you tried using a Before hook for an Example? It doesn't work for me, it may be a bug or feature.
Scenario Outline: Doing some tests
Given a step
When I do some &input&
Then I should get some &output&
|daily 2 o |
Before('@daily') do
p "before daily"
Nothing happens. It seems that cucumber doesn't know about Before examples. Using Ruby Cucumber 1.3.10
I'm sitting in a debugger, in an 'after scenario' hook, with 'scenario' showing as a Cucumber:Ast:OutlineTable::ExampleRow and 'scenario.source_tag_names' returns the feature tags and the scenario outline tags.
Rooting around in the object directly, although I can easily find the table and cells references, I can't even locate the example table's tags by force.
We're successfully using tags on the example tables to filter them in and out (per the accepted answer), so Cucumber obviously sees them for that purpose, but that's all those tags appear to be available for - not for hooks, and not for observing from hooks.
Seems a bit inconsistent to me.

Given I like print "lol"
Scenario Outline: Words printing

And implementation:
from lettuce import step
@step('I like print "([^"]+)"')
def step_impl(step, word):
print word
When PyCharm lettuce test runner execute feature its run first scenario without problems but second is never executed (however it knows that there is other scenario) - so it looks like:
