Exploratory Testing
Exploratory testing is an approach to software testing that is concisely described as simultaneous learning, test design and test execution. Cem Kaner, who coined the term in 1984, defines exploratory testing as "a style of software testing that emphasizes the personal freedom and responsibility of the individual tester to continually optimize the quality of his/her work by treating test-related learning, test design, test execution, and test result interpretation as mutually supportive activities that run in parallel throughout the project." While the software is being tested, the tester learns things that together with experience and creativity generates new good tests to run. Exploratory testing is often thought of as a black box testing technique. Instead, those who have studied it consider it a test ''approach'' that can be applied to any test technique, at any stage in the development process. The key is not the test technique nor the item being tested or reviewed; the key is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software Testing
Software testing is the act of examining the artifacts and the behavior of the software under test by validation and verification. Software testing can also provide an objective, independent view of the software to allow the business to appreciate and understand the risks of software implementation. Test techniques include, but not necessarily limited to: * analyzing the product requirements for completeness and correctness in various contexts like industry perspective, business perspective, feasibility and viability of implementation, usability, performance, security, infrastructure considerations, etc. * reviewing the product architecture and the overall design of the product * working with product developers on improvement in coding techniques, design patterns, tests that can be written as part of code based on various techniques like boundary conditions, etc. * executing a program or application with the intent of examining behavior * reviewing the deployment infrastructure a ...

Test Script
A test script in software testing is a set of instructions that will be performed on the system under test to test that the system functions as expected. Types of test scripts There are various means for executing test scripts. These last two types are also done in manual testing. * Manual testing. These are more commonly called test cases. * Automated testing. ** Short program written in a programming language used to test part of the functionality of a software system. Test scripts written as a short program can either be written using a special automated functional GUI test tool (such as HP QuickTest Professional, Borland SilkTest, IBM TPNS and Rational Robot) or in a well-known programming language (such as C++, C#, Tcl, Expect, Java, PHP, Perl, Powershell, Python, or Ruby). As documented in IEEE, ISO and IEC. ** Extensively parameterized short programs a.k.a. Data-driven testing ** Reusable steps created in a table a.k.a. keyword-driven or table-driven testing. Usag ...

Ad Hoc Testing
Ad hoc testing is a commonly used term for planned software testing that is performed without initial test case documentation; however, ad hoc testing can also be applied to other scientific research and quality control efforts. Ad hoc tests are useful for adding additional confidence to a resulting product or process, as well as quickly spotting important defects or inefficiencies, but they have some disadvantages, such as having inherent uncertainties in their performance and not being as useful without proper documentation post-execution and -completion. Occasionally, ad hoc testing is compared to exploratory testing as being less rigorous, though others argue that ad hoc testing still has value as "improvised testing that deals well with verifying a specific subject." Ad hoc testing of software When testing software, that testing may be methodical or more improvisational. Methodical testing will include written test cases, which detail their own set of specified inputs, executio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Program Specification
In computer science, formal specifications are mathematically based techniques whose purpose are to help with the implementation of systems and software. They are used to describe a system, to analyze its behavior, and to aid in its design by verifying key properties of interest through rigorous and effective reasoning tools. These specifications are ''formal'' in the sense that they have a syntax, their semantics fall within one domain, and they are able to be used to infer useful information. Motivation In each passing decade, computer systems have become increasingly more powerful and, as a result, they have become more impactful to society. Because of this, better techniques are needed to assist in the design and implementation of reliable software. Established engineering disciplines use mathematical analysis as the foundation of creating and validating product design. Formal specifications are one such way to achieve this in software engineering reliability as once predicted. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software Requirement
In product development and process optimization, a requirement is a singular documented physical or functional need that a particular design, product or process aims to satisfy. It is commonly used in a formal sense in engineering design, including for example in systems engineering, software engineering, or enterprise engineering. It is a broad concept that could speak to any necessary (or sometimes desired) function, attribute, capability, characteristic, or quality of a system for it to have value and utility to a customer, organization, internal user, or other stakeholder. Requirements can come with different levels of specificity; for example, a requirement specification or requirement "spec" (often imprecisely referred to as "the" spec/specs, but there are actually different sorts of specifications) refers to an explicit, highly objective/clear (and often quantitative) requirement (or sometimes, ''set'' of requirements) to be satisfied by a material, design, product, or se ...

Deductive Reasoning
Deductive reasoning is the mental process of drawing deductive inferences. An inference is deductively valid if its conclusion follows logically from its premises, i.e. if it is impossible for the premises to be true and the conclusion to be false. For example, the inference from the premises "all men are mortal" and "Socrates is a man" to the conclusion "Socrates is mortal" is deductively valid. An argument is ''sound'' if it is ''valid'' and all its premises are true. Some theorists define deduction in terms of the intentions of the author: they have to intend for the premises to offer deductive support to the conclusion. With the help of this modification, it is possible to distinguish valid from invalid deductive reasoning: it is invalid if the author's belief about the deductive support is false, but even invalid deductive reasoning is a form of deductive reasoning. Psychology is interested in deductive reasoning as a psychological process, i.e. how people ''actually'' draw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Session-based Testing
Session-based testing is a software test method that aims to combine accountability and exploratory testing to provide rapid defect discovery, creative on-the-fly test design, management control and metrics reporting. The method can also be used in conjunction with scenario testing. Session-based testing was developed in 2000 by Jonathan and James Marcus Bach. Session-based testing can be used to introduce measurement and control to an immature test process and can form a foundation for significant improvements in productivity and error detection. Session-based testing can offer benefits when formal requirements are not present, incomplete, or changing rapidly. Elements of session-based testing Mission The mission in Session Based Test Management identifies the purpose of the session, helping to focus the session while still allowing for exploration of the system under test. According to Jon Bach, one of the co-founders of the methodology, the mission explains "what we are testin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pair Testing
Pair testing is a software development technique in which two team members work together at one keyboard to test the software application. One does the testing and the other analyzes or reviews the testing. This can be done between one tester and developer or business analyst or between two testers with both participants taking turns at driving the keyboard. Description This can be more related to pair programming and exploratory testing of agile software development where two team members are sitting together to test the software application. This will help both the members to learn more about the application. This will narrow down the root cause of the problem while continuous testing. Developer can find out which portion of the source code is affected by the bug. This track can help to make the solid test cases and narrowing the problem for the next time. Benefits and drawbacks * The developer can learn more about the software application by exploring with the tes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mindset
Mindset is an "established set of attitudes, esp. regarded as typical of a particular group's social or cultural values; the outlook, philosophy, or values of a person; (now also more generally) frame of mind, attitude, ecte: anddisposition." A mindset may also arise from a person's world view or philosophy of life. A firmly established mindset could create a powerful incentive to adopt or accept prior behaviors, choices, or tools, sometimes referred to as ''cognitive inertia'', or "groupthink." Within these phenomena, it is often difficult to counteract its effects upon analysis and decision making processes. In cognitive psychology, a mindset represents the cognitive processes activated in response to a given task (French, 2016). According to French and Chang (2016), scholarly conceptualizations of mindset shift "to the varied definitions and conceptualizations" which "demarcates this literature via a novel categorization using the construct of mindset."

Test Method
A test method is a method for a test in science or engineering, such as a physical test, chemical test, or statistical test. It is a definitive procedure that produces a test result. In order to ensure accurate and relevant test results, a test method should be "explicit, unambiguous, and experimentally feasible.", as well as effective and reproducible. A test can be considered an observation or experiment that determines one or more characteristics of a given sample, product, process, or service. The purpose of testing involves a prior determination of expected observation and a comparison of that expectation to what one actually observes. The results of testing can be qualitative (yes/no), quantitative (a measured value), or categorical and can be derived from personal observation or the output of a precision measuring instrument. Usually the test result is the dependent variable, the measured response based on the particular conditions of the test or the level of the independ ...
