Class ExcelDataLoader

java.lang.Object

org.easetech.easytest.loader.ExcelDataLoader

All Implemented Interfaces:

Loader

public class ExcelDataLoader
extends Object
implements Loader

An implementation of Loader for the EXCEL(xls) based files. This Loader is responsible for reading a list of xls based files and converting them into a data structure which is understandable by the EasyTest framework. It expects the format of the Excel file to be like this :
testGetItems LibraryId itemType searchText
<EMPTY CELL> 4 journal batman
<EMPTY CELL> 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 EXCEL file represents a single set of test data.
Note the leading <EMPTY CELL> in the test data row. It denotes that this cell does not contain any value.It tells the framework that testGetItems is just a method name and does not have any value.
An Excel 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 data for multiple test methods in a single Excel 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
