Web Testing
Web testing is software testing that focuses on web applications. Complete testing of a web-based system before going live can help address issues before the system is revealed to the public. Issues may include the security of the web application, the basic functionality of the site, its accessibility to disabled and fully able users, its ability to adapt to the multitude of desktops, devices, and operating systems, as well as readiness for expected traffic and number of users and the ability to survive a massive spike in user traffic, both of which are related to load testing. Web application performance tool A web application performance tool (WAPT) is used to test web applications and web related interfaces. These tools are used for performance, load and stress testing of web applications, web sites, web API, web servers and other web interfaces. WAPT tends to simulate virtual users which will repeat either recorded URLs or specified URL and allows the users to specify numbe ...

Software Testing
Software testing is the act of checking whether software satisfies expectations. Software testing can provide objective, independent information about the Quality (business), quality of software and the risk of its failure to a User (computing), user or sponsor. Software testing can determine the Correctness (computer science), correctness of software for specific Scenario (computing), scenarios but cannot determine correctness for all scenarios. It cannot find all software bug, bugs. Based on the criteria for measuring correctness from an test oracle, oracle, software testing employs principles and mechanisms that might recognize a problem. Examples of oracles include specifications, Design by Contract, contracts, comparable products, past versions of the same product, inferences about intended or expected purpose, user or customer expectations, relevant standards, and applicable laws. Software testing is often dynamic in nature; running the software to verify actual output ...

Web Application
A web application (or web app) is application software that is created with web technologies and runs via a web browser. Web applications emerged during the late 1990s and allowed for the server to dynamically build a response to the request, in contrast to static web pages. Web applications are commonly distributed via a web server. There are several different tier systems that web applications use to communicate between the web browsers, the client interface, and server data. Each system has its own uses as they function in different ways. However, there are many security risks that developers must be aware of during development; proper measures to protect user data are vital. Web applications are often constructed with the use of a web application framework. Single-page applications (SPAs) and progressive web apps (PWAs) are two architectural approaches to creating web applications that provide a user experience similar to native apps, including features such as smoo ...

Load Testing
Load testing is the process of putting demand on a structure or system and measuring its response. Software load testing Physical load testing Many types of machinery, engines, structures, and motors are load tested. The load may be at a designated safe working load (SWL), full load, or at an aggravated level of load. The governing contract, technical specification or test method contains the details of conducting the test. The purpose of a mechanical load test is to verify that all the component parts of a structure including materials, base-fixings are fit for task and loading it is designed for. Several types of load testing are employed * Static testing is when a designated constant load is applied for a specified time. * Dynamic testing is when a variable or moving load is applied. * Cyclical testing consists of repeated loading and unloading for specified cycles, durations and conditions. The ''Supply of Machinery (Safety) Regulation 1992 UK'' state that load testi ...

Web Site
A website (also written as a web site) is any web page whose content is identified by a common domain name and is published on at least one web server. Websites are typically dedicated to a particular topic or purpose, such as news, education, commerce, entertainment, or social media. Hyperlinking between web pages guides the navigation of the site, which often starts with a home page. The List of most-visited websites, most-visited sites are Google Search, Google, YouTube, and Facebook. All publicly-accessible websites collectively constitute the World Wide Web. There are also private websites that can only be accessed on a intranet, private network, such as a company's internal website for its employees. User (computing), Users can access websites on a range of devices, including desktop computer, desktops, laptops, tablet computer, tablets, and smartphones. The application software, app used on these devices is called a web browser. Background The World Wide Web (WWW) was ...

Web API
A web API is an application programming interface (API) for either a web server or a web browser. As a web development concept, it can be related to a web application's client side (including any web frameworks being used). A server-side web API consists of one or more publicly exposed endpoints to a defined request–response message system, typically expressed in JSON or XML by means of an HTTP-based web server. A server API (SAPI) is not considered a server-side web API, unless it is publicly accessible by a remote web application. Client side A client-side web API is a programmatic interface to extend functionality within a web browser or other HTTP client. Originally these were most commonly in the form of native plug-in browser extensions however most newer ones target standardized JavaScript bindings. The Mozilla Foundation created their WebAPI specification which is designed to help replace native mobile applications with HTML5 applications. Google created thei ...

Web Servers
A web server is computer software and underlying hardware that accepts requests via HTTP (the network protocol created to distribute web content) or its secure variant HTTPS. A user agent, commonly a web browser or web crawler, initiates communication by making a request for a web page or other resource using HTTP, and the server responds with the content of that resource or an error message. A web server can also accept and store resources sent from the user agent if configured to do so. The hardware used to run a web server can vary according to the volume of requests that it needs to handle. At the low end of the range are embedded systems, such as a router that runs a small web server as its configuration interface. A high-traffic Internet website might handle requests with hundreds of servers that run on racks of high-speed computers. A resource sent from a web server can be a pre-existing file ( static content) available to the web server, or it can be generated ...

GraphQL
GraphQL is a data query and manipulation language that allows specifying what data is to be retrieved (" declarative data fetching") or modified. A GraphQL server can process a client query using data from separate sources and present the results in a unified graph. The language is not tied to any specific database or storage engine. There are several open-source runtime engines for GraphQL. History Facebook started GraphQL development in 2012 and released a draft specification and reference implementation as open source in 2015. In 2018, GraphQL was moved to the newly established GraphQL Foundation, hosted by the non-profit Linux Foundation. On February 9, 2018, the GraphQL Schema Definition Language became part of the specification. Many popular public APIs adopted GraphQL as the default way to access them. These include public APIs of Facebook, GitHub, Yelp, Shopify, Google Directions API and many others. Design GraphQL supports reading, writing (mutating), ...

Software Performance Testing
In software quality assurance, performance testing is in general a testing practice performed to determine how a system performs in terms of responsiveness and stability under a particular workload. It can also serve to investigate, measure, validate or verify other quality attributes of the system, such as scalability, reliability and resource usage. Performance testing, a subset of performance engineering, is a computer science practice which strives to build performance standards into the implementation, design and architecture of a system. Testing types Load testing Software load testing, Load testing is the simplest form of performance testing. A load test is usually conducted to understand the behavior of the system under a specific expected load. This load can be the expected concurrent number of users on the application software, application performing a specific number of Transaction processing, transactions within the set duration. This test will give out the respo ...

Web Server Benchmarking
Web server benchmarking is the process of estimating a web server performance in order to find if the server can serve sufficiently high workload. Key parameters The performance is usually measured in terms of: *Number of requests that can be served per second (depending on the type of request, etc.); *Latency response time in milliseconds for each new connection or request; *Throughput in bytes per second (depending on file size, cached or not cached content, available network bandwidth, etc.). The measurements must be performed under a varying load of clients and requests per client. Tools for benchmarking Load testing (stress/performance testing) a web server can be performed using automation/analysis tools such as: * Apache JMeter, an open-source Java load testing tool * ApacheBench (or ab), a command line program bundled with Apache HTTP Server *Siege, an open-source web-server load testing and benchmarking tool * Wrk, an open-source C load testing tool *Locust, an open-so ...

Lydia Ash
Lydia (; ) was an Iron Age kingdom situated in western Anatolia, in modern-day Turkey. Later, it became an important province of the Achaemenid Empire and then the Roman Empire. Its capital was Sardis. At some point before 800 BC, the Lydian people achieved some sort of political cohesion, and existed as an independent kingdom by the 600s BC. At its greatest extent, during the 7th century BC, it covered all of western Anatolia. In 546 BC, it became a satrapy of the Achaemenid Empire, known as ''Sparda'' in Old Persian. In 133 BC, it became part of the Roman province of Asia. Lydian coins, made of electrum, are among the oldest in existence, dated to around the 7th century BC. Geography Lydia is generally located east of ancient Ionia in the modern western Turkish provinces of Uşak, Manisa and inland İzmir.Rhodes, P.J.
