I have performed both Manual and Automated testing and found some basic thing in Test Case. Test Case is nothing but it shows your defined activities and steps which you will perform in your testing. In Manual testing test case is written manually but in automation testing it is generated by testing tools and is known as Test Script. Test Case and Test Script both are same because both of them perform same activities but has only one difference that test case is written in simple sentences and test script is generated in form script. Script is light weight programming language.
