What is data driven testing?
Data is used to drive test cases and suites from an external data feed.
Data can be feed from xls, xlsx, csv, xml and databases

Why data driven testing is required?
Allows testing of the application with multiple sets of data values
Separates the test case data from the executable test script
Allows reusing of Actions and Functions in different tests
Data driven test cases are flexible and easy to maintain
The same test cases are executed several times which helps to reduce efforts and code
Any changes in the test script do not effect the test data

DataRow and DynamicData Attribute
DataRow
Attribute to define in-line data for a test method.
Example :
[DataRow("NARENDRA","MODI","01/01/2019")]
DynamicData
Attribute to define dynamic data for a test method.
Example :
[DynamicData(nameof(GetData), DynamicDataSourceType.Method)]

Code :
[TestClass]
public class UnitTest1
{
[TestMethod]
[DataRow("Narendra","Modi","01/01/2019")]
[DataRow("donald", "trump", "07/01/2020")]
[DataRow("BORIS", "JOHNSON", "12/31/2021")]
public void DataDrivenTestingUsingDataRow(string fName, string lName, string eDate)
{
IWebDriver driver = new ChromeDriver();
driver.Manage().Window.Maximize();
driver.Url = "http://uitestpractice.com/Students/Create";

driver.FindElement(By.Id("FirstName")).SendKeys(fName);
driver.FindElement(By.Id("LastName")).SendKeys(lName);
driver.FindElement(By.Id("EnrollmentDate")).SendKeys(eDate);
driver.FindElement(By.XPath("//input[@type='submit']")).Click();

driver.Quit();
}

[DynamicData(nameof(GetData), DynamicDataSourceType.Method)]
[TestMethod]
