Passing arrays of variable in specflow - arrays

Question

Is there a way to pass an array of parameters instead of passing each parameter individually?
For example I have the following scenarios:
When i login to a site
then <firstname>, <lastname>, <middleName>, <Desingation>, <Street>, <Apartmentno> are valid
The list can go on above. Instead can I pass all the above variables in an array?

Answer 1

You can pass a comma separated string and then transform it into a list:
When i login to a site
then 'Joe,Bloggs,Peter,Mr,Some street,15' are valid
[Then("'(.*)' are valid")]
public void ValuesAreValid(List<String> values)
{
}
[StepArgumentTransformation]
public List<String> TransformToListOfString(string commaSeparatedList)
{
return commaSeparatedList.Split(",").ToList();
}
if you want the values to come from examples then you could do this instead:
When I login to a site
then '<values>' are valid
Examples
| values |
| Joe,Bloggs,Peter,Mr,Some street,15|
| Joe,Bloggs,Peter,Mr,Some street,16,SomethingElse,Blah|
If you want to use a table then you could do this instead:
When I login to a site
then the following values are valid
| FirstName | LastName | MiddleName | Greeting| Etc | Etc |
| Joe | Bloggs | Peter | Mr | you get| The Idea|
(you could omit the headers if you want and just use the row values I think)
you can also use examples with this:
When I login to a site
then the following values are valid
| FirstName | LastName | MiddleName | Greeting | Etc | Etc |
| <name> | <lastName>| <middleName>| <greeting>| <etc> | <etc> |

This might be of help:
https://github.com/techtalk/SpecFlow/wiki/Step-Argument-Conversions
Add the following code snippet to your Common Step Definition File:
[StepArgumentTransformation]
public string[] TransformToArrayOfStrings(string commaSeparatedStepArgumentValues)
{
string sourceString = commaSeparatedStepArgumentValues;
string[] stringSeparators = new string[] { "," };
return sourceString.Split(stringSeparators, StringSplitOptions.None);
}
SpecFlow will then automatically convert all comma-separated values in the SpecFlow Steps data table into an array of strings.
Then in your individual step binding function, change the type of the input parameter as string[] as in snippet below:
[Then(#"the expected value is '(.*)'")]
public void ThenTheExpectedValueIs(string[] p0)
{
//ScenarioContext.Current.Pending();
Assert.AreEqual(25, Convert.ToInt32(p0[0]));
Assert.AreEqual(36, Convert.ToInt32(p0[1]));
Assert.AreEqual(79, Convert.ToInt32(p0[2]));
}
Then, based on your expected value for a test step, you may want to apply the appropriate type conversion.

Just transfer the data as a string Example:
Then LEDS 0, 1, 7 are on
[Then(#"LEDS (.*) are on(.*)]
public void ThenLEDAreOn(string p0)
{
int count = p0.Split(',').Length - 1;
string[] Leds_on = p0.Split(',');
foreach (string s in LEDs_on)
{
int.TryParse(s, out LEDS[index]);
index++;
}
}
Then you have your values as integers in an array
