All Implemented Interfaces:

Loader

public class CSVDataLoader
extends Object
implements Loader

An implementation of Loader for the CSV based files. This Loader is responsible for reading and writing to a list of CSV based files and converting them into a data structure which is understandable by the EasyTest framework. It expects the format of the CSV file to be like this :
testGetItems,LibraryId,itemType,searchText
,4,journal,batman ,2,ebook,spiderman
where testGetItems represents the name of the test method for which the test data is being defined,
LibraryId,itemType,searchText represents the test data fields for the test method, and
,4,journal,batman (and ,2,ebook,spiderman) represents the actual test data to be passed to the test method. Each row in the CSV file represents a single set of test data.
Note the leading "," in the test data row. it is mandatory to use and tells the framework that testGetItems is just a method name and does not have any value.
A CSV cannot have a blank line in between test data whether it is for a single test or for multiple tests. The framework is capable of handling multiple test datas for multiple test methods in a single CSV file. Although a user can choose to define the test data in multiple files as well.
If you want to pass a Collection to the test method, just separate each instance with a ":". For eg. to pass a list of Itemids , pass them as a colon separated list like this -> 12:34:5777:9090
This Loader can also write the data back to the file, either for the given method names or for all the methods in the file. This is handy when we want to write the output data back to the file.
