Writing Data-Driven Tests Using Excel in Java

A crucial concept in Selenium automation is Data-Driven Testing — a method where test data is separated from the test script logic, allowing testers to run the same test with multiple sets of data. This enhances test efficiency, coverage, and maintainability.

One of the most common approaches to implementing data-driven testing in Java is by using Excel files as the source of input data, especially in frameworks like TestNG.

1. Why Data-Driven Testing?

Data-driven testing allows automation testers to:

Run multiple test cases using different data sets

Avoid code duplication

Maintain test data separately from test scripts

Simplify test maintenance

2. How It’s Done Using Excel in Java

To read and write data from Excel files in Java, the Apache POI library is widely used. This library enables testers to connect Excel with Java-based frameworks like Selenium and TestNG.

Typical Implementation:

Create an Excel file with input data like usernames, passwords, and expected results.

Use Apache POI to read data from Excel rows and cells.

Integrate data into the test methods using @DataProvider annotation in TestNG.

Sample Snippet:

java

@DataProvider(name = "loginData")

public Object[][] getData() {

    return ExcelUtils.readExcel("data.xlsx", "Sheet1");

}

@Test(dataProvider = "loginData")

public void loginTest(String username, String password) {

    // Selenium code to perform login with provided credentials

}

At IHub Talent, you’ll receive hands-on training on how to:

Use Apache POI to handle Excel files

Design scalable frameworks using TestNG

Perform validations based on dynamic input sets

Build reusable data-driven scripts

3. Real-Time Project Exposure

The Live Internship Program at IHub Talent ensures that you apply these concepts in real-world scenarios, such as login testing, registration flows, and form validations using multiple data inputs.
