What is Correlation: It is a Process to handle dynamic values in our Script. Here the dynamic value is replaced by a variable which we assign or capture from the server response.
Ways to do correlation: There are two ways to do this Correlation.
They are as follows:
- Auto-Correlation: The Correlation Engine in LR Package captures the value and replaces it with another value
- Manual Correlation: Understanding of the Script and its response is highly needed to do this. It is bit complex to do Manual Correlation sometimes but this is always the preferred method to handle Dynamic Values in our Script
Usually the Manual Correlation is done by capturing the dynamic value which is present in between the Static left and right Boundaries.
Objective: The intention of this article is that to give a method which will be useful when we wanted to capture and handle Dynamic Values when even the Left and right Boundaries are also dynamic.
The Solution can be much simple, Instead of determining the boundaries to the String we can actually use Text flags.
Before Getting into the Topic we should know about the Text Flags:
Text flags are the Flag used just after the text with Forward Slash.
Some of the commonly known and used Text flags are:
- /IC to ignore the case
- /BIN to specify binary data
- /DIG to interpret the pound sign (#) as a wildcard for a single digit
- /ALNUM<case> to interpret the caret sign (^) as a wildcard for a single US–ASCII alphanumeric character
