Read different values from Excel file every time when test case runs - selenium

Question

I have create a excel file with some codes and I am using RepeatRule class to execute my test case 100 times in one class. I need to use different 100 codes every time the test will run rather than using the same code again and again. Below is my code
#Test
#Repeat(2)
public void Test() throws Exception {
Success.setUp();
Success.allowcokkies();
//Success.Ecoomerecemain();
File source = new File("/Users/test/Downloads/Voucher-codes.xlsx");
FileInputStream input = new FileInputStream(source); // Read Excel Data
XSSFWorkbook wb = new XSSFWorkbook(input);
XSSFSheet sheet = wb.getSheetAt(0);
int noOfColumns = sheet.getRow(0).getLastCellNum();
System.out.println(noOfColumns);
String[] Headers = new String[noOfColumns];
int j=0;
Headers[j] = sheet.getRow(0).getCell(j).getStringCellValue();
Success.getDriver().findElement(By.xpath("//*[#id=\"code\"]")).sendKeys(sheet.getRow(0).getCell(j).getStringCellValue());// Enter Coupon
Thread.sleep(2000);
}
#After
public void testdown()
{
Success.getDriver().quit();
This is repeat class code:
public class RepeatRule implements TestRule {
public static class RepeatStatement extends Statement {
private final Statement statement;
private final int repeat;
public RepeatStatement(Statement statement, int repeat) {
this.statement = statement;
this.repeat = repeat;
}
#Override
public void evaluate() throws Throwable {
for (int i = 0; i < repeat; i++) {
statement.evaluate();
}
}
}
#Override
public Statement apply(Statement statement, Description description) {
Statement result = statement;
Repeat repeat = description.getAnnotation(Repeat.class);
if (repeat != null) {
int times = repeat.value();
result = new RepeatStatement(statement, times);
}
return result;
}
}
How can I read different codes every time while using Repeat rule?

Answer 1

The easy way to do this is a JUnit 5 parameterized test. Save your Excel sheet as csv and use the following test method:
#ParameterizedTest
#CsvFileSource(resources = "/Users/test/Downloads/Voucher-codes.csv", numLinesToSkip = 1)
void testVoucher(String coupon) {
...
Success.getDriver().findElement(By.xpath("//*[#id=\"code\"]")).sendKeys(coupon);// Enter Coupon
...
}
Parameterized tests are possible with JUnit 4 as well. An example is described in the JUnit Wiki. You can even use the Excel sheet as a data provider with your POI code.
Another solution would be using #BeforeEach, where you could update a coupon field couponIndex in your test class and access the right row by the value of this field.
Success.getDriver().findElement(By.xpath("//*[#id=\"code\"]")).sendKeys(sheet.getRow(couponIndex).getCell(j).getStringCellValue());// Enter Coupon
I would recommend using a parameterized test.
