Data Provider with Hashtable

We have seen how to use the data-provider with the help of an excel file. Now let us discuss how to use the Data-provider with the help of Hashtable.

We can create a TestNG test class where we can keep the implementation of the Data-provider with the help of HashTable:

package SeleniumTest.SeleniumTest;

import java.util.Hashtable;

import org.testng.annotations.DataProvider;

import org.testng.annotations.Test;

public class DataProviderHashTable {

@DataProvider(name="data")

public static Object[][] credentials() throws Exception //throws Exception

{

int cols=2;

int rows=2;

Object[][] data=new Object[rows][1];

Hashtable<String,String> table=null;

for(int i=1; i<=rows;i++)

{

table = new Hashtable<String,String>();

for(int j=0 ; j<cols; j++)

{

try {

table.put(ExcelReading.getCellData(0, j), ExcelReading.getCellData(i, j));

} catch (Exception e) {

e.printStackTrace();

}

data[i-1][0] = table;

}

return data;

}

@Test(dataProvider="data")

public void testCase(Hashtable<String,String> data)

{

// Implement the method as per requirement

}

We can now implement the test method as per our requirement and use the data from the data-provider.
