Iyi pratik ornegi olarak Yaml dosyalarinda cift tirnak kullanimi

Yaml dosyalarda yes, on, true gibi degerlerin hepsi boolean true degerine eslestiriliyor. Bu da gozden kactiginda tespiti zor buglara neden oluyor.

Bu tarz sorunlardan bastan kacinmak icin string alanlari cift tirnak ile cevrelemek iyi bir pratik.

It can use text mask to bounds of text certain begin and end indices. Enjoy your data driven test via spock framework :)
public class TextMasker {
public static String mask(String text, int begin, int end) {
if (Objects.isNull(text)) {
return null;
}
if (areIndexesInBoundOfText(text, begin, end)) {
String firstDisplayablePart = text.substring(0, begin);
String secondDisplayablePart = text.substring(end);
