We can use an Excel sheet as a source of input. We can access data from excel sheet using DataProvider annotation and pass arguments through @Test methods. Mainly this approach is used in Data Driven Framework.
Data Driven Framework: A data-driven framework is used to run the same script for a huge amount of test data from any source like properties files, excel files etc. On the other hand, a Key Driven framework is based on keywords which are used to control the execution of the script without modifying the actual code. A tester has to just set the keywords which he/she wants to execute during a review cycle. Nowadays, the hybrid framework is used which is the combination of Keyword Driven and Data Driven Framework.
Please refer Simple example of Key Driven Framework using the excel sheet.
DataProvider
A data provider is defined with @DataProvider annotation. This annotation contains only one attribute its name. If the name is not supplied, the data provider’s name automatically defaults to the method’s name. A data provider returns an array of objects as mentioned below:
The return type of methods using “@DataProvider(name=”testdata”)” should be Object[Row][Col].
Row – defines the number of rows in excel files
– It also defines the total number of times test get repeat and it treats it as individual test case in TestNg
Col – defines number of columns in excel file
– defines total number of parameters in the test data
@DataProvider(name=“excelData”)
public Object[ ][ ] readExcel()
{
Object[ ][ ] obj=new Object[2][2];
return obj;
}
@Test(dataProvider=“excelData”)
Public void testMethod(String arg1, String arg2)
{
System.out.println(arg1);
System.out.println(arg2);
}
