TestNG Parameters are the arguments that we pass to the test methods. There are two ways through which we will pass the parameters to the test methods:

TestNG Parameters
TestNG DataProviders

In this blog , we’ll study the TestNG Parameters. we’ll study the parameterization within the xml file.

Suppose we would like to line the worldwide variables such url settings, username, password or API Keys, there are some values which are constant altogether the test cases, in such case we use the TestNG Parameters.

TestNG Parameters are present within the xml file. they will be applied either inside the tag or tag. If we would like to use the parameters to all or any the test cases, then the parameters are applied inside the tag. If the parameter is restricted to a specific folder, then the parameter is applied within a tag.

Let’s understand through an example.

First case: When Parameters are applied below the tag.

Step 1: Open the Eclipse.

Step 2: We create three class files, i.e., Sum.java, Subtract.java, and Multiply.java.

Sum.java

package com.tecklearn;
import org.testng.annotations.Test;
import org.testng.annotations.Parameters;
public class Sum
{
@Test
@Parameters({"a","b"})
public void add(int c, int d)
{
int sum=c+d;
System.out.println("Sum of two numbers : "+sum);
}
}

Substract.java

package com.tecklearn;
import org.testng.annotations.Parameters;
import org.testng.annotations.Test;
public class Subtract
{
@Test
@Parameters({"a","b"})
public void add(int c, int d)
{
int subtract=c-d;
System.out.println("Subtraction of two numbers : "+subtract);
}
}

Multiply.java

package com.tecklearn;
import org.testng.annotations.Parameters;
import org.testng.annotations.Test;
public class Multiply
{
@Test
@Parameters({"a","b"})
public void add(int c, int d)
{
int mul=c*d;
System.out.println("Multiplication of two numbers : "+mul);
}
}

Step 3: Now, we create the testng.xml file.

testng.xml

<?xml version="1.0" encoding="UTF-8"?> 
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd"> 
<!-- Test -->
<!-- Suite -->

In the above testng.xml file, we pass the parameters which are valid to all or any the classes.

Step 4: Run the testng.xml file.

Output

1 64

Second case: When parameters are specific.

Step 1: Open the Eclipse.

Step 2: We create two class files. i.e., Fruits.java and Vegetable.java.

Fruits.java

package com.tecklearn;
import org.testng.annotations.Test;
import org.testng.annotations.Parameters;
public class Fruits
{
@Test
@Parameters("mango")
public void mango(String m)
{
System.out.println("Fruits names are: ");
System.out.println(m);
}
@Test

@Parameters("orange")
public void orange(String o)
{
System.out.println(o);
}
}

Vegetable.java

package com.tecklearn;
import org.testng.annotations.Test;
import org.testng.annotations.Parameters;
public class Vegetable
{
@Test
@Parameters("Cauliflower")
public void c(String m)
{
System.out.println("Vegetable names are :");
System.out.println(m);
}
@Test
@Parameters("Ladyfinger")
public void orange(String l)
{
System.out.println(l);
}
}

Step 3: Now, we create the testng.xml file.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<!-- Suite -->

In the above testng.xml, we specify the parameters during a particular folder means the parameters are applied to those classes which are specific thereto folder.

Step 4: Run the testng.xml file.

Output

2 63

Concept of TestNG Parameters

TestNG Parameters are the arguments that we pass to the test methods. There are two ways through which we will pass the parameters to the test methods:

TestNG Parameters
TestNG DataProviders

In this blog , we’ll study the TestNG Parameters. we’ll study the parameterization within the xml file.

{

public void add(int c, int d)
{
int sum=c+d;
System.out.println("Sum of two numbers : "+sum);
}
}

Subtract.java

package com.tecklearn;
import org.testng.annotations.Parameters;
import org.testng.annotations.Test;
public class Subtract
{
@Test
