If i.e. following value is passed to getParameterList:

// has two spaces here -----------\/
citrus:concat('{"lorem": ["ipsum",  "other"]}'),

it results in following String:

//note missing comma
{"lorem": ["ipsum""other"]}

(see tests for more examples)

assertEquals(resolveFunction("citrus:concat('Hello Yes, I like Citrus!', 'Hello Yes,we like Citrus!')", context), "Hello Yes, I like Citrus!Hello Yes,we like Citrus!");
assertEquals(resolveFunction("citrus:concat('Hello Yes, I like Citrus, and this is great!', 'Hello Yes,we like Citrus, and this is great!')", context), "Hello Yes, I like Citrus, and this is great!Hello Yes,we like Citrus, and this is great!");

// assertEquals(resolveFunction("citrus:upperCase(''Yes, I like Citrus!)", context), "''YES, I LIKE CITRUS!");

I don't really understand those three test - are they really intended like that?

Because compared i.E. to CSV (if I recall correct), if quotes are present in a string, they need to be inside quotes.

so, apparently unequal amount of quotes were accepted / ignored. and these few tests here do no longer pass, because of the provided fix in the parser. is that what you mean?

* @param parameterString comma separated parameter string.
* @return list of parameters.

public static List<String> getParameterList(String parameterString) {
List<String> parameterList = new ArrayList<>();
return new ParameterParser(parameterString).parse();

The longer I think about that... wouldn't it be easier to just use a CSV-Parser for that?

Hey @bbortt
Your thoughts on that?

hm.. I think CSV uses double quotes for concatenation. that's a bit problematic in the context of Java. other than that, I do too think that it's the same parsing logic.
