DID YOU KNOW ?
A/B testing - sometimes called split testing, is comparing two versions of a web page to see which one performs better. You compare two web pages by showing the two variants (let's call them A and B) to similar visitors at the same time. The one that gives a better conversion rate, wins!
Introduction Open source doesn't just mean access to the source code. The distribution terms of open-source software must comply with the following criteria:
Commercial Off-the-Shelf software became a major part of any organization on building the maintenance and working flow capabilities. COTS software are even integrated into the testing processes without much of increase in the testers activities and effort. More and more companies are breaking their heads to understand what is better for them, COTS against In-House developed frameworks.
advantages ? Domain-specific languages allow solutions to be expressed in the idiom and at the level of abstraction of the problem domain. Consequently, domain experts themselves can understand, validate, modify, and often even develop domain-specific language programs. ? Self-documenting code.
Unix shell scripts give a good example of a domain-specific language for data organization. They can manipulate data in files or user input in many different ways. Domain abstractions and notations include streams (such as stdin and stdout) and operations on streams (such as redirection and pipe). These abstractions combine to make a robust language to talk about the flow and organization of data.
There are several usage patterns for domain-specific languages: ? processing with standalone tools, invoked via direct user operation, often on the command line or from a Makefile (e.g., the GraphViz tool set) ? domain-specific languages which are implemented using programming language macro systems, and which are converted or expanded into a host general purpose language at compile-time or read-time ? embedded (or internal) domain-specific languages, implemented as libraries which exploit the syntax of their host general purpose language or a subset thereof, while adding domain-specific language elements (data types, routines, methods, macros etc.).
A domain-specific language is created specifically to solve problems in a particular domain and is not intended to be able to solve problems outside it (although that may be technically possible). In contrast, general-purpose languages are created to solve problems in many domains. The domain can also be a business area.
The concept isn't new—special-purpose programming languages and all kinds of modeling/specification languages have always existed, but the term has become more popular due to the rise of domain-specific modeling. Examples of domain-specific languages include Logo for children, Verilog and VHSIC hardware description languages, R and S languages for statistics, Mata for matrix programming,
Software testing types are important and a must know, even when talking about Automated testing. The Best Automated testing is a kind of testing that runs on the needed strategy and method the same way it was done manually. Today, we still see companies that manage two testing systems, one for manual testing and the other for automatic testing. But, as I said before, this will change, and is already changing. Thanks to smart Testing Management tools and ALM’s.
Commercial Tools/Commercial software or in other words Payware, is a software product that stands for sale or serves commercial purposes.
Commercial software is most often proprietary software, which means that it is licensed under exclusive legal right of the copyright holder, but even free software package may also be commercial software.
Some enterprise architects believe that SOA can help businesses respond more quickly and cost-effectively to changing market-conditions. This style of architecture promotes reuse at the macro (service) level rather than micro (classes) level. It can also simplify interconnection to – and usage of – existing IT (legacy) assets.
OA Manifesto Service orientation is a paradigm that frames what you do. Service-oriented architecture (SOA) is a type of architecture that results from applying service orientation. We have been applying service orientation to help organizations consistently deliver sustainable business value, with increased agility and cost effectiveness, in line with changing business needs.
SOA and Web service protocols Implementers commonly build SOAs using web services standards (for example, SOAP) that have gained broad industry acceptance. These standards (also referred to as Web Service specifications) also provide greater interoperability and some protection from lock-in to proprietary vendor software.
Web services can implement a service-oriented architecture. Web services make functional building-blocks accessible over standard Internet protocols independent of platforms and programming languages. These services can represent either new applications or just wrappers around existing legacy systems to make them network-enabled. Each SOA building block can play one or both of two roles
In order to efficiently use a SOA, the architecture must meet the following requirements: • Interoperability among different systems and programming languages that provides the basis for integration between applications on different platforms through a communication protocol.
Commentators have provided multiple definitions of SOA. The OASIS group and the Open Group have both created formal definitions. OASIS defines SOA as the following:A paradigm for organizing and utilizing distributed capabilities that may be under the control of different ownership domains. It provides a uniform means to offer, discover, interact with and use capabilities to produce desired effects consistent with measurable preconditions and expectations.
Service Oriented Architecture (SOA) is a network design that uses Uniform Resource Locators (URL) to define and locate services provided businesses. As it appears, many proclaim it is the simplest of network service access methods. The concept simply use the current web structure with some sophistication in "browser accessing" the requested URL.
The primary purpose to calibrate a set automation tools is to perform data driven automated testing applications on Android.
XUnit - Code Driven Testing What are xUnit tools? But, before answering this question lets define and understand the ‘code driven testing’ term
Code Driven Testing Code driven test automation is a key feature of Agile software development, where it is known as Test-driven development (TDD). Unit tests are written to define the functionality before the code is written. Only when all tests pass is the code considered complete. Proponents argue that it produces software that is both more reliable and less costly than code that is tested by manual exploration. It is considered more reliable because the code coverage is better, and because it is run constantly during development rather than once at the end of a waterfall development cycle. The developer discovers defects immediately upon making a change, when it is least expensive to fix. Finally, code refactoring is safer; transforming the code into a simpler form with less code duplication, but equivalent behavior, is much less likely to introduce new defects.
You can start with the simple RIO formula, but then you have to take in consideration all the other criteria according to your product, service and targets. You will have to accumulate your product values and targets into numbers, for example: How much it is worth for you to be first in quality level ? How much it is worth to you to be first and fast into market ? How complicated is your product, can you keep the high quality with profession less resources.
To test a GUI, you need a reliable method of finding components of interest, clicking buttons, selecting cells in a table, dragging things about. In fact you need a ‘Bot’ that will activate all The User Interfaces, Buttons, Windows, etc. like human user does. The GUI test need a full description of the expected behavior of the User Interface controls, and its process is similar to any developing process. Gui test also had to make sure that the GUI stands on the customer requirements as well.
