How to use Regular Expression Evaluator in QTP 11

In QTP 11,  Regular Expression Evaluator is a new tool added by HP. This helps us test the regular expressions on sample input strings. This is very useful tool.

To open Regular Expression Evaluator, you have to click on tools menu. There you will find option for Regular Expression Evaluator. Click on it.

1. Once Regular Expression Evaluator is open, you can enter the Regular Expression inside the first edit box circled in red
2. In large text box, you can enter sample text string that you want to test.
3. Then you can click on the highlight button.

If the match is found, that is colored in yellow. It also shows you total number of matches found at the bottom of the Regular Expression Evaluator window.

Once you are sure that Regular Expression you have designed is working correct, you can use that in Object repository or in descriptive programming.
