Problem Statement

Using a well-known testing-specific library/module/suite for your language, write some tests for your language's entry in Palindrome. If your language does not have a testing specific library well known to the language's community then state this or omit the language.

Let's start with the solution:

Step by Step solution about How to resolve the algorithm Test a function step by step in the C# programming language

The provided C# code is a set of unit tests for a program that detects if a string is a palindrome.

  • The first set of tests uses Microsoft's VisualStudio.TestTools.UnitTesting framework while the second set uses the NUnit framework.

  • Both sets of tests have two test methods:

    • PalindromeDetectorCanUnderstandPalindrome tests that the program correctly identifies palindromes (a string that reads the same forwards and backwards).
    • PalindromeDetectorUnderstandsNonPalindrome tests that the program correctly identifies non-palindromes.

  • In the PalindromeDetectorCanUnderstandPalindrome method, it defines as expected a boolean value true and then compares it with the actual result of the IsPalindrome and IsPalindromeNonRecursive functions.

  • In the PalindromeDetectorUnderstandNonPalindrome method, it defines as expected a boolean value true and then compares it with the actual result of the IsPalindrome and IsPalindromeNonRecursive functions.
