---------------------------------------

             Summary: @NamedParam arguments don't get their default value when only named parameters are used in the method call
                 Key: GROOVY-9158
                 URL: https://issues.apache.org/jira/browse/GROOVY-9158
             Project: Groovy
          Issue Type: Bug
    Affects Versions: 2.5.7
            Reporter: Mathieu Grelier


See the code below.

@NamedParam only method signatures with default values for not required ones should be possible, with corresponding named parameters only method calls.
{code:groovy}
import groovy.transform.NamedParam
import groovy.transform.NamedVariant
import static groovy.test.GroovyAssert.shouldFail
    
class NamedParamTestClass {

    Map getArgs(def arg1, def arg2) {
        Map passedArgs = [:]
        passedArgs << ["arg1":arg1, "arg2":arg2]
        passedArgs
    }
     
    @NamedVariant
    Map onlyNamedArgs(@NamedParam(required = true) String arg1, @NamedParam(required = false) String arg2 = "expected default value") {
        getArgs(arg1, arg2)
    }
    
    @NamedVariant
    Map primitiveTypeNotRequired(@NamedParam(required = false) String arg1, @NamedParam(required = false) int arg2 = 1) {
        getArgs(arg1, arg2)
    }
}

def test = new NamedParamTestClass()
Map result

result = test.onlyNamedArgs("a positional value for @NamedParam arg1")
assert result.getAt("arg2") == "expected default value"

result = test.onlyNamedArgs(arg1:"a named parameter value for @NamedParam arg1")
shouldFail(AssertionError) {
    assert result.getAt("arg2") == "expected default value" :  "arg2 was not given its default value"
}
assert result.getAt("arg2") == null

shouldFail(MissingMethodException) {
    result = test.primitiveTypeNotRequired(arg1:'1') // called with named arg
}
{code}
Last test shows also that MissingMethodException occurs when a primitive type is used with @NamedParam.
