Google recently change their dashboard, in such a way it confuses webmasters to test their robots.txt. The sad thing about this update is that: You can never check robots.txt unless you have verified it under your account.
This appears to be true. But there is a way:
If you have a existing verified account of any website. You can use it to test for robots.txt in another website. Let say you have this following given:
VERIFIED in your account: http://www.thiswebsiteverified.com
NOT VERIFIED in your account: http://www.notverifiedingwt.com
Step 1: Change the domain name of the URLS not verified to verified, you can easily do a find and replace function in MS Word. For example, you have this following URLs that you would like to test:
http://www.notverifiedingwt.com/url1.php
http://www.notverifiedingwt.com/url2?x=1.php
http://www.notverifiedingwt.com/url3?x=4.php
If you do a find a replace using MS Word, find “notverifiedingwt.com”, then replace all with “thiswebsiteverified.com”, after performing that operation it will become:
http://www.thiswebsiteverified.com/url1.php
http://www.thiswebsiteverified.com/url2?x=1.php
http://www.thiswebsiteverified.com/url3?x=4.php
Step 2.Now go to GWT (under site configuration–> crawler access) account of http://www.thiswebsiteverified.com, go to robots.txt analysis tool. Copy and paste the robots.txt that would like to test for http://www.notverifiedingwt.com, but in the URLS to be tested, copy and paste these URLs( so that you can use the tool):
http://www.thiswebsiteverified.com/url1.php
http://www.thiswebsiteverified.com/url2?x=1.php
http://www.thiswebsiteverified.com/url3?x=4.php
Now you can test your formulated robots.txt in whatever domains even without verification. Just “find and replace” the unverified URLs with verified domain.

Finally sorted out my robots file. Thanks for the help!
