How do I use sendKeys to input multiple random value in different rows?

Question

I have a text field to input voucher code, and I already tried this;

driver.findElement(By.id("voucher_code")).sendKeys("AL982", "OK992", "PO982", "SX982", "LQ925");

In the text field it become like this:

AL982OK992PO982SX982LQ925

What I want is to be like this:

AL982
OK992
PO982
SX982
LQ925

Because the system read, 1 row = 1 voucher code.

1. How do I use sendKeys to input multiple value in different rows?

2. And is it possible to shorten my code for multiple random value like above?, (in real case we have 1000 voucher code)

Answer 1

\n is your friend here. sendKeys actually recognizes them as linebreaks, at least in chrome, ff an edge. Can't say anything about other webdriver implementations as I don't use them.

void addVouchers(String[] codes, WebElement input) {
    for(String code: codes) {
         input.sendKeys(code+"\n");
   } 
}

should do what you want.

Answer 2

When you are passing comma seperated value, it will append all of it and pass it to field.

you can try this to pass multiple values in different fields.

String[] voucherCodes = {"AL982", "OK992", "PO982", "SX982", "LQ925"};
WebElement field = driver.findElement(By.id("yourIdforEveryField"));
for (String voucher : voucherCodes) {
    field.sendKeys(voucher);
};
