Menu Software Testing Software testing is an analysis carried out to give stakeholders with information regarding the quality of the service or product under test. In other words, software testing means analyzing a characteristic or ability of a software program or system.
The importance of any Thesis on software testing factor varies from application to application. In the typical business system usability and maintainability are the key factors, while for a one-time scientific program neither may be significant.
Our testing, to be fully effective, must be geared to measuring each relevant factor and thus forcing quality to become tangible and visible. The drawbacks are that it can only validate that the software works for the specified test cases. A finite number of tests can not validate that the software works for all situations.
On the contrary, only one failed test is sufficient enough to show that the software does not work. Dirty tests, or negative tests, refers to the tests aiming at breaking the software, or showing that it does not work.
A piece of software must have sufficient exception handling capabilities to survive a significant level of dirty tests.
A testable design is a design that can be easily validated, falsified and maintained. Because testing is a rigorous effort and requires significant time and cost, design for testability is also an important design rule for software development.
For reliability estimation [Kaner93] [Lyu95] Software reliability has important relations with many aspects of software, including the structure, and the amount of testing it has been subjected to.
Based on an operational profile an estimate of the relative frequency of use of various inputs to the program [Lyu95]testing can serve as a statistical sampling method to gain failure data for reliability estimation.
Software testing is not mature. It still remains an art, because we still cannot make it a science. We are still using the same testing techniques invented years ago, some of which are crafted methods or heuristics rather than good engineering methods.
Software testing can be costly, but not testing software is even more expensive, especially in places that human lives are at stake. Solving the software-testing problem is no easier than solving the Turing halting problem.
We can never be sure that a piece of software is correct. We can never be sure that the specifications are correct. No verification system can verify every correct program. We can never be certain that a verification system is correct either. Key Concepts Taxonomy There is a plethora of testing methods and testing techniques, serving multiple purposes in different life cycle phases.
Classified by purpose, software testing can be divided into: Classified by life-cycle phase, software testing can be classified into the following categories: By scope, software testing can be categorized as follows: Correctness testing Correctness is the minimum requirement of software, the essential purpose of testing.
Correctness testing will need some type of oracle, to tell the right behavior from the wrong one. The tester may or may not know the inside details of the software module under test, e. Therefore, either a white-box point of view or black-box point of view can be taken in testing software.
We must note that the black-box and white-box ideas are not limited in correctness testing only. Black-box testing The black-box approach is a testing method in which test data are derived from the specified functional requirements without regard to the final program structure.
Because only the functionality of the software module is of concern, black-box testing also mainly refers to functional testing -- a testing method emphasized on executing the functions and examination of their input and output data. In testing, various inputs are exercised and the outputs are compared against specification to validate the correctness.Have you considered testing from the perspective of software security.
