Using a Duplicate Text Line Remover in Cross-browser Testing
A repeated text line remover can be useful if you're doing cross-browser testing. For example, if you're writing browser tests for a multi-line text form and you have a requirement that the form can't have the same line appear twice, then with this program, you can quickly create tests cases for this scenario. You can write two sets of tests – the first test set makes sure the input with no duplicate lines is valid, and the second test set makes sure that if there are duplicate lines in the input, then this case is correctly handled and this input is not allowed in the application. Another use case is given a list of names, places, or phone numbers, filter and print only the unique ones. And another use case is comparing two data lists for duplicate entries.
