How to test a method within a class

Question

I am fairly new to both unit testing and apex. I am trying to test a method within a class, but i keep getting an error which tells me method does not exist. I have a feeling that perhaps my syntax is incorrect, but in my previous test that i have created where I am doing something very similar. The syntax does in fact work properly which is where I am confused.

In my model ApplicationContactMappingSettingModel I have a the public method:

public List<FieldMap> getFieldMap(String category){
//code to throw exception in here
}

In my test class

static testMethod void test_get_field_map(){
   Application_Contact_Mapping_Settings__c acmSetting = ApplicationMappingTestDataUtils.createOneApplicationContactMappingSetting('string in here', true, 'another string');
ApplicationContactMappingSettingsModel scmSettingsModel = new ApplicationContactMappingSettingsModel();
}

When I try to get the public List from my class by writing this:

//in my model the class of FieldMap has these operators
scmSettingsModel.FieldMap('string','another string', 'another string')

List<FieldMap> category = scmSettingsModel.getFieldMap();

I get the error message telling me the method does not exist Does anyone know the proper way of calling this method? Please let me know if there is more information i can add to make this more helpful, Thanks.

Answer 1

You declare the method like this:

public List<FieldMap> getFieldMap(String category)

But you use it like this:

List<FieldMap> category = scmSettingsModel.getFieldMap();

Note that the method signatures do not match: the method accepts a string but you did not pass one in.
