Effective Software Testing Strategy
The present day world is slave to the world of computers. Almost no one can manage without the widespread help provided by the use of computers. However the evils associated with it have become a cause of concern over the last couple of centuries. The will to fight back against the ongoing cyber crimes has led to the development of the wide range of security software systems available in the market. These security software applications are indispensable units of the computers that ensure all kinds of unwanted infiltrations that may prove to be harmful to the machine. The market is filled up by innumerable security software being developed by millions from different parts of the world. Therefore, there needs to be a way to test each and every one of them in order to determine the levels of their utility.
The process of software testing is used to measure the quality of the software developed by professional of different software producing companies. The term of quality of the software programs are limited to ideas like the correctness, completeness, security etc. However this method of testing software applications may also be inclusive of a number of technical requirements, as prescribed under the ISO standards. The ISO 9226 standard commonly refers to properties like efficiency, reliability, portability, compatibility, maintainability and usability that is to be followed by all software testing strategies
The most commonly used software testing strategies that are favored by most IEEE today are:
White box testing- White box testing is the process that deals with the internal logic and structure of the code. The technique of white box testing is also known as glass, open box or clear box testing. Huge number of software training companies has recommended the use of these methods. The person using this technique needs to deal with the code and therefore should possess sufficient knowledge on this area. The white box testing allows easy ways of testing the kind of input that might help in testing of the application. The software testing business is more or less dependent on the system of white box testing. Black box testing- This is a very commonly used strategy as it does not require any kind of knowledge of internal design or codes. The black box testing promises a number of software training tips which allows individuals in testing the requirements and functionality of the work product/software application. Gray box testing- This is exclusively used by client server testers who mainly use a database as a repository of information. Individuals with the knowledge of algorithm of the concerned software may also apply these techniques. The process of using data warehouse implementation is also important for verifying the correctness of data stored in the database of the software applications. The software testing business is on a constant flourish due to the efforts of the software testing companies that have emerged in recent times. The online software training companies have made notable contributions in providing software training tips to computer users of different countries. Software testing is the process used to help identify the correctness , completeness , security and quality of developed computer software. Testing is a process of executing a program or application in the intent of finding errors. Software testing is any activity aimed at evaluating an attribute or capability of a program or system and determining that it meets its required results. The difficulty in software testing stems from the complexity of software: we can not completely test a program with moderate complexity. Software testing is a critical phase of the software life-cycle which can be very effective if performed rigorously. Formal specifications offer the bases for rigorous testing practices. Software testing is traditionally seen as a difficult and time consuming activity that is hard to embed in the software development process. Software testing is a process to test the product against the specifications. It involves interaction with the product to detect the available bugs and also to check the reliability of the product. Software testing is an empirical technical investigation conducted to provide stakeholders with information about the quality of the product or service under test , with respect to the context in which it is intended to operate. This includes, but is not limited to, the process of executing a program or application with the intent of finding software bugs. Software testing is one of the important factors that determine success and failure of software. Fault can result serious impact to Company in terms of cost and efficiency. Software testing is both a discipline and a process. Though software testing is part of the software development process, it should not be considered part of software development. Software testing is a fast growing discipline. Industry increases IT hiring each year, and recent years have seen a marked increase in emphasis on quality of software engineering in general, and testing in particular. Software testing is the process of attempting to make this assessment. Software testing is essential, but it is definitely not the core activity of most organizations that require it. Outsourcing will enable a company to concentrate on it's core activities while software testing experts can handle the work efficiently, ensuring quality results. Software testing is uselss if it isn't complete. Code coverage of statements and branches cannot find all software bugs. Software Testing is not as easy as you might think of. Needless to say, It's one of the most important and difficult tasks in the entire gamut of software development life cycle process. Software testing is usually performed for one of two reasons: (1) defect detection, and (2) reliability estimation. The problem of applying software testing to defect detection is that software can only suggest the presence of flaws, not their absence (unless the testing is exhaustive). Software testing is a discipline that's become pretty good at finding requirements-based defects. As an industry, we've developed and nurtured test harnesses, tools, techniques, and talent to find many bugs before software is ever released. Automation refers to the removal of human interaction with a process and placing it under machine or program control. In our case, the process in question was software testing. Automated functional testing (in general) is not "very limited". In fact regression testing a modern software development project demands automated testing. Automating these tests is the only way to guarantee that they will be repeated exactly the same way, but like automating music, the lack of interpretation in execution can limit the results. A computer can only find the problems we predict and program it to find. Automating repetitive tasks gives your team time to spend on more challenging and rewarding projects. Team members improve their skill sets and confidence and, in turn, pass those gains on to their organization. Manual testing therefore cannot be ignored. It must be embraced! Manual software testing is the process of manually testing software (having the possible forms for example, user interfaces navigation, information submission, or attempt to hack the software or database etc.), carried out by an individual or individuals. Manual software testing is labor-intensive and slow. Developers and testers must ensure that newly developed products or product enhancements meet functional and performance requirements and that those products are reliable and able to operate consistently under peak loads. The risks of releasing a product that is not yet ready are greater now than ever before because of the change in expectations and demands of the end users. Development tools are becoming smarter, generating more code. Code reuse is exploding. Bugs get incorporated due to many factors. Starting form miscommunication, defecting software coding, use of software development tools, timely delivery pressures, and the ever changing requirements, all can contribute for flawed software. Exploratory testing should usually identify many such bugs embedded in new software.Simply put the job of a software tester is in finding and reporting differences between actual behavior of a software product and its expected behavior. The more technical knowledge the person has the more jobs that person could qualify for. Simpler tools require less training and less effort to work with, and are often less expensive to purchase and install. Second, adopt tools that provide value. Simply put, software testing is hard to do well. Exploratory Testing
Exploratory testing is becoming more and more important in e-commerce applications. Because requirements are often slim to none. Exploratory testing is complementary to procedural testing as it adds a random effect, simulating the various ways an end user will use the product. It catches bugs that are caused by the interaction between the various states within the software. Exploratory testing is the discipline of designing and executing tests simultaneously. Does this mean that there is no plan to it? Exploratory testing is one such technique where significant investment has been made to improve its utility in most large software development companies like Microsoft. Exploratory testing is sometimes confused with "ad hoc" testing. Ad hoc testing normally refers to a process of improvised, impromptu bug searching. Exploratory testing is often said to be the opposite of scripted testing. Automated testing is often said to be the opposite of manual testing. Exploratory testing is a very advanced technique that needs to be performed by experienced testing specialists. The outcome of each test will decide the likely route for the next test. Exploratory testing is a particular family of test practices defined as "simultaneous learning, test design, and test execution.".It can be thought of as a mental martial art. The term was coined (in the software field, anyway) by Cem Kaner in the late eighties, but he didn't write very much about it, and few people used the term. Exploratory testing is not weak, random or ineffective. However, the power of exploratory testing rests with the individual tester. Exploratory testing is especially useful in complex testing situations, when little is known about the product, or as part of preparing a set of scripted tests. The basic rule is this: exploratory testing is called for any time the next test you should perform is not obvious, or when you want to go beyond the obvious. Exploratory testing is an approach to testing that emphasizes the freedom and responsibility of the tester to continually optimize the value of his work. It is the process of three mutually supportive activities done in parallel: learning, test design, and test execution. Exploratory testing is traditionally difficult to track because so much testing is decided and executed all at once without documenting each test that is run. For this reason, test cases are the primary traditional testing approach. Exploratory testing is a less formal testing approach where test design, execution, and logging are performed concurrently, based on a test charter. In this instance the software had already been through previous iterations with more formal testing. Exploratory testing is conducted early in the formation of an initiative to develop message platforms and creative content. Creative concepts addressing specific message platforms are tested against among small focus groups comprised of the Campaign?s target audience. Exploratory testing is very common, but in most writing and training about testing it is barely mentioned and generally misunderstood. Some writers consider it a primary and essential practice. Exploratory testing is the most efficient and effective approach to testing software. It produces useful results from the first hours of testing, and finds the biggest bugs faster than any other approach. Exploratory testing doesn't have to be paired with a scripted testing program. You can put an extremely high-quality application into production using nothing but exploratory testing, and you wouldn't be the first project manager to do it. Exploratory testers add permanent value to projects by constructing practical notes, which provide short valuable logs that record what was discovered during each testing session. Exploratory testing as approach has a legacy. Until recently, I was under the impression that adhoc testing is quick and monkey type of testing (often connected with sloppy testing) where you just play with application in order to find some bugs that are out of specification. Exploratory testing is widely done in software testing. However, it is performed in many different ways. Exploratory testing, in the old meaning of the word, should be incorporated into what we normally refer to as Scripted testing. Perhaps on a very rudimentary level, at least in comparison with what Scripted tests normally do, but still in the same context as Scripted tests in terms of repeatability, formal reference and thoroughness. Exploratory testing addresses both application functionality and stability. This method is not a comprehensive test method, and it is not a substitute for a more formal method if application experts are available. Exploratory testing is simultaneous test design, execution and learning. This doesn't tell you how to do it well, just how to recognize it. Associates
