Advice for comparing strings | selenium-training

Not a question, but a quick friendly advice. When comparing two strings for equality ( as in homework Test Case 2 for title,subtitle and author) do not use == to check for equality, but use built-in String method .equals instead like: stringA.equals(stringB) Hope everyone is doing ok on the homework ;)

That is great advice, Oleg!

It is even better to use equalsIgnoreCase instead of equals in case the 2 String variables have different casing (one has lowercase, the other has uppercase letters):

String textA = "Home Page";
String textB = "home page";

//this will return false because the 2 text values have different casing
boolean areEqual = textA.equals(textB);

You can fix it by converting both strings to lower case before comparing them:

String textA = "Home Page";
String textB = "home page";

//this will return true
textA = textA.toLowerCase();
textB = textB.toLowerCase();
boolean areEqual = textA.equals(textB);

But it is simpler to just use

String textA = "Home Page";
String textB = "home page";

//this will return true
boolean areEqual = textA.equalsIgnoreCase(textB);
