The application of regular expression in Rational Function Tester

Overview

A regular expression is a literal pattern consisting of ordinary characters and special characters that describe one or more strings to be matched when looking for a text body. While regular expressions are a very complex system, in an automated script you can use a few simple syntax to make the control more effective when it is recognized. Using regular expressions during automated testing can reduce the cost of development and help maintain automation scripts. This article first summarizes the regular expressions commonly used rules and examples; then it analyzes the difference between two regular expression classes Regularrexpression and Regex in RFT, and finally lists the common application examples of regular expressions in RFT. To help beginners of Rational Function test better understand regular expressions so that they can be used quickly in their own test projects, making automated scripts more flexible and maintainable, and saving development costs.
