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. A decision table is a good way to deal with different combination inputs with their associated outputs and also called causeeffect table.
This is opposed to software development that allows software to be added that is not proven to meet. What are the disadvantages of test coverage in software testing. We can find the easily gaps in requirements, test cases and defects at an early level and code level. Software testing ppt software testing unit testing.

So friends enjoy my ppt on software testing process and if you have any query than free to ask just enter the comment below and if you like my work than please share this ppt with your friends. A test case is a set of actions executed to verify a particular feature or functionality of your software application. One of the most challenging aspects of software testing is designing good test cases. Requirements based testing process overview bender rbt, inc. It is important that your tests are designed well, or you could fail to identify bugs and defects in your software during testing. For example, if youre testing the login page, include login page in the title of the test case. Ciss divide all possible inputs into classes partitions such that there is a finite number of input equivalence classes you may reasonably assume that the program behaves analogously for inputs in the same class a test with a representative value from a class is sufficient if representative detects fault then other class members will detect the same fault.
