What is Test Case? How to write a good test case?

Test Cases are the implementation of a test case design which will help the software tester to detect defects in the application or the system being tested. This should be the primary goal of any test case or set of test cases. When I write a test case, I think of both types of test cases, positive test cases and negative test cases. Positive test cases are those which execute the happy path in the application and make sure that the happy path is working fine. Negative test cases as the name suggests are destructive test cases which are documented with some out-of-box thinking to break the system.
A Test Case should be documented in a manner that is useful for the current test cycle and any future test cycles. At a bare minimum each test case should contain: Sr No, Summary or Title, Description, Steps to reproduce, Expected Results, Actual Results and Status of the test case or remarks.

well this statment is very comprehensive but i thnk that a good tester or a QA engr.. should always sit and intend to crash the software for the first time. This can really help in learning and better quality of the software.

A test case is a document that describes an input, action, or event and an expected response, to determine if a feature of an application is working correctly. A test case should contain particulars such as test case identifier, test case name, objective, test conditions/setup, input data requirements, steps, and expected results.

Techniques for writing Good Test cases

1.First do some home work what do you want to test for a requirement

2.claisfy the type of requirement(GUI,Functional,Database..)

3.Gather maximum information related and affected areas with this requirement

4.In Deails section write this information(if you are using TD) which will be more useful for other testers

5.Use very simple English and general words in writing the description.(please don't show ur english talent here).All test steps should be low level.

6.Provide test data(if possible).

7.Write in details SQL Queries(it will save time while executing. Some people will not share their SQL knowledge in the scripts.)

8.Write clear Expected Result.

If you follow all the steps it will helpful to other testers and developes while execution and debugging(for developers

“A test case has components that describe an input, action or event and an expected response, to determine if a feature of an application is working correctly.”
