Assuming regular PCRE-style regex flavors   If you want to check for it as a single  full word  it s  bTest b  with appropriate flags for case insensitivity if desired and delimiters for your programming language   b represents a  word boundary   that is  a point between characters where a word can be considered to start or end  For example  since spaces are used to separate words  there will be a word boundary on either side of a space   If you want to check for it as part of the word  it s just Test  again with appropriate flags for case insensitivity  Note that usually  dedicated  substring  methods tend to be faster in this case  because it removes the overhead of parsing the regex
