If new features are being added to the current version of software, then writing a test case for that operation is done differently. First plan how many new test cases are to be written for current version. If the new feature is part of any existing feature, then share the test cases of new and existing features among them.
Regression testing is typically the largest test effort in commercial software development, [50] due to checking numerous details in prior software features, and even new software can be developed while using some old test cases to test parts of the new design to ensure prior functionality is still supported.
While testing software projects, certain test cases will be treated as the most important ones, and if they fail the product cannot be released. Some other test cases may be of lesser functional importance, or even cosmetic and if they fail, we can release the product without much compromise on the functionality. These priority levels must be ...
The result of the test design is a set of test cases based on the specification. These test cases can be designed prior to the implementation starts, and should be implementation-independent. Test first way of test design is very important as efficiently supports defect prevention. Based on the application and the present test coverage further ...
Smoke tests are a subset of test cases that cover the most important functionality of a component or system, used to aid assessment of whether main functions of the software appear to work correctly. [ 1 ] [ 2 ] When used to determine if a computer program should be subjected to further, more fine-grained testing, a smoke test may be called a ...

Level Test Design (LTD): Detailing test cases and the expected results as well as test pass criteria. Level Test Case (LTC): Specifying the test data for use in running the test cases identified in the Level Test Design. Level Test Procedure (LTPr): Detailing how to run each test, including any set-up preconditions and the steps that need to be ...
Test cases underlie testing that is methodical rather than haphazard. A battery of test cases can be built to produce the desired coverage of the software being tested. Formally defined test cases allow the same tests to be run repeatedly against successive versions of the software, allowing for effective and consistent regression testing. [12]
