29. Data-Driven Testing & External Test Data Providers

Java POJO for Test Data

public class UserCredentials {
    private String email;
    private String password;
    private String expectedRole;
// Getters and Setters
    public String getEmail() { return email; }
    public String getPassword() { return password; }
    public String getExpectedRole() { return expectedRole; }
}
// Data provider streaming multiple scenarios:
List<UserCredentials> testUsers = Arrays.asList(
    new UserCredentials("admin@targetqa.com", "adminPass", "ADMIN"),
    new UserCredentials("user@targetqa.com", "userPass", "STANDARD")
);
