What is data-driven testing in TestNG?

Data-driven testing in TestNG allows you to run the same test with multiple sets of data, improving test coverage.

How do I implement data-driven testing in my TestNG project?

You can implement it using the @DataProvider annotation to supply data to your test methods.

Can you give me an example of a data provider in TestNG?

Sure! Here's a simple example:

@DataProvider(name = "data-provider")
public Object[][] dataProviderMethod() {
    return new Object[][] {
        { "data1", 1 },
        { "data2", 2 }
    };
}

What are the benefits of using data-driven testing?

It enhances test coverage, reduces code duplication, and allows for easier maintenance of test cases.
