How to create test Conditions and Cases

Test Conditions (What to Test) : Test Condition is the specification that a tester must follow for testing an Application. An item or event of a component or system that could be verified by one or more test cases, e.g a function, transaction, feature, quality attribute or structural element. For ex. When User Name and Password are valid then application will move forward.

Test Cases (How to Test) : A Test case is a set of conditions or variables under which a tester will determine whether a system under test satisfies requirements or works correctly. 
The process of developing test cases can also help find problems in the requirements or design of an application.

Test Basis : Test Basis is defined as the source of information or the document that is needed to write test cases and also for test analysis. It is also an activity during the phase of Test Analysis and design in the testing process.

Test Case Specification : A test specification is a document determining what functions and features of the software are to be tested during the test procedure, in what way, how often they must be verified, etc.

Examples for writing good Test Case.

• Test Cases need to be simple and transparent. 
• Create Test Case with End User in Mind
• Avoid test case repetition
• Do not Assume
• Ensure 100% Coverage
• Test Cases must be identifiable
• Implement Testing Techniques
• Self-Cleaning
• Peer Review
