Regular expression are used when object changes dynamically.For example: We have a input button name "Hello" on website then it changes to "Hello11" and after some time changes to "Hello123" so to handle such type of situation we will use regular expression * there as "Hello*". There are many more special characters which generally used as a regular expression.

as per nitin answer i agree but we can use regular expression in test cases also how it is like shown below:
if we have lengthy statements in test cases we can use this
for ex:in testdata alphanumerics in lowercase is valid for login module we can write;
username is:test_data23
[a-z0-9_]+
like this we can write
