Question

I have some tests that check strings that are displayed to the user.

I don’t wish the test to fail to due to changes in the indentations or line breaks etc. So I am

You can also use the following custom function

        public static string ExceptChars(this string str, IEnumerable toExclude)
        {
            StringBuilder sb = new StringBuilder();
            for (int i = 0; i < str.Length; i++)
            {
                char c = str[i];
                if (!toExclude.Contains(c))
                    sb.Append(c);
            }
            return sb.ToString();
        }

        public static bool SpaceInsenstiveComparision(this string stringa, string stringb)
        {
            return stringa.ExceptChars(new[] { ' ', '\t', '\n', '\r' }).Equals(stringb.ExceptChars(new[] { ' ', '\t', '\n', '\r' }));
        }

And then use it following way

"Te  st".SpaceInsenstiveComparision("Te st");
