Test your Regix exprestion in easy way

During our work you have to write regex expression and test it

and it's confusing and consuming a lot of times

I found this useful website that help in

Example

if you want to make sure the input is :

• ^[a-zA-Z ]+$ String and space
• ^[a-zA-Z]+$ string only

I will select String and space 
kindly follow the steps below :

1. go to website http://regexr.com/
2. write the ^[a-zA-Z ]+$ in  expectation 
3. write the free testing text in TEXT
4. check matching (en the end of expression ) 

once the letter is blue --> its matching (image1)
if there is no shadow -->it's not matching  (image2)

image 1 - the text match the expression

image 2- text not matching the regex
