Practice - 5 Tasks

1fill in blank

easy

Complete the code to declare a DataProvider method in TestNG.

Selenium Java

import org.testng.annotations.DataProvider;

@DataProvider(name = "testData")
public Object[][] [1]() {
    return new Object[][] {
        {"user1", "pass1"},
        {"user2", "pass2"}
    };
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using invalid method names or keywords as method names.

Forgetting to annotate the method with @DataProvider.

The method name for a DataProvider can be any valid method name. Here, getData is used as the method name.

2fill in blank

medium

Complete the test method annotation to use the DataProvider named "testData".

Selenium Java

import org.testng.annotations.Test;

@Test(dataProvider = [1])
public void loginTest(String username, String password) {
    // test code here
}

Drag options to blanks, or click blank then click option'

A"dataProvider"

B"userPass"

C"testData"

D"loginData"

💡 Hint

Common Mistakes

Using the method name instead of the DataProvider name.

Forgetting to put the name in quotes.

The dataProvider attribute in the @Test annotation must match the name of the DataProvider method, which is "testData" here.

3fill in blank

hard

Fix the error in the DataProvider method signature to make it valid.

Selenium Java

@DataProvider(name = "loginData")
public [1] loginData() {
    return new Object[][] {
        {"admin", "1234"},
        {"guest", "guest"}
    };
}

Drag options to blanks, or click blank then click option'

Bvoid

CString[][]

Dint[][]

💡 Hint

Common Mistakes

Using void as return type.

Using primitive arrays like int[][] instead of Object[][].

A DataProvider method must return an Object[][] array containing test data sets.

4fill in blank

hard

Fill both blanks to correctly link the DataProvider to the test method and accept parameters.

Selenium Java

@Test(dataProvider = [1])
public void [2](String user, String pass) {
    System.out.println("User: " + user + ", Pass: " + pass);
}

Drag options to blanks, or click blank then click option'

A"loginData"

BloginTest

C"testData"

DdataTest

💡 Hint

Common Mistakes

Mismatching DataProvider names.

Incorrect method names that do not follow Java naming rules.

The test method must specify the correct DataProvider name and have a matching method name.

5fill in blank

hard

Fill all three blanks to create a DataProvider method and a test method that uses it with parameters.

Selenium Java

import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;

@DataProvider(name = [1])
public Object[][] [2]() {
    return new Object[][] {
        {"admin", "admin123"},
        {"user", "user123"}
    };
}

@Test(dataProvider = [3])
public void verifyLogin(String username, String password) {
    System.out.println(username + " logs in with " + password);
}

Drag options to blanks, or click blank then click option'

A"userData"

BuserData

DuserDataProvider

💡 Hint

Common Mistakes

Using different names in @DataProvider and @Test annotations.

Putting quotes around method names.

The DataProvider name in the annotation and the dataProvider attribute in @Test must match exactly as strings. The method name must be a valid Java method name.
