PhantomJS is a headless WebKit scriptable with JavaScript API that allows testing and automating web pages without requiring a browser to be displayed. It renders pages and outputs the results, supporting many test frameworks. PhantomJS can capture screenshots, monitor network performance, and automate tasks like testing, page scraping, and generating images/charts from websites. It works across platforms and provides a fast, native implementation of web standards without emulation.
The ISTQB certification provides standardized testing qualifications across multiple levels - Foundation, Advanced, and Expert. The Foundation level ensures understanding of fundamental testing practices, Advanced focuses on more sophisticated techniques, and Expert covers leading-edge methods. Over 100,000 testers across 46 countries have been certified, demonstrating mastery of best practices. Certification benefits testers, organizations, and advances the software testing profession as a whole.
The document discusses software testing and preparation for the ISTQB Foundation Certification exam. It covers topics like quality assurance and control, different software development and testing models, types of testing, the testing life cycle, defect management, and test automation. It provides descriptions and explanations of these key testing concepts.
Mobility testing overview and instructionsAlextyur
Mobility testing involves driving a test device in a real cellular network to identify issues like dropped calls or data transfer problems during handovers between cells. Preparation includes creating test plans and routes, organizing equipment and tasks, and addressing common problems like delays, lost equipment, or needing emergency assistance. The document provides guidance on planning, conducting, and reporting on mobility tests to validate cellular network performance.
This document provides an overview and examples of how to use PhantomJS, an open-source headless WebKit with a JavaScript API. It can be used for headless website testing, screen capture, page automation, and network monitoring. Examples are given for taking screen captures of full or partial pages, evaluating JavaScript on pages, injecting scripts, and reading command line arguments. More information can be found at the PhantomJS website.
Owning Web Performance with PhantomJS 2 - Fluent 2016Wesley Hales
Running a synthetic testing server or script to measure web performance is a great entry point into the world of automated web-page testing. We have an abundance of standardized APIs to measure every part of how the page renders in the browser. PhantomJS 2, released in 2015, gives us the ability to measure navigation timing APIs in an automated fashion.
Wesley Hales introduces the basics of creating a simple PhantomJS script that only extracts the performance data we need (from the W3C Navigation Timing API) and explains how this script can be Dockerized and run across many different nodes and regions of the Web. You’ll walk away with a new view on automated web-performance testing and the tools required to setup a simulated RUM network.

The document discusses the history and current state of software testing certification. It covers:
1) The ISTQB/ISEB certification program began in the late 1990s and early 2000s to standardize software testing knowledge and professionalize the field.
2) The certifications include Foundation, Practitioner, and Specialist levels to cater to candidates with different experience levels.
3) International collaboration through the ISTQB has led to widespread adoption of a common certification syllabus across many countries.
There are many types of tools that support testing across the entire software development lifecycle. While automation can help improve testing, automating and testing require separate skills. Effective use of tools requires identifying the appropriate tests to automate through planning and effort, while maintaining control over the test automation process. Tools should support requirements testing, static analysis, test design, test data preparation, test execution, comparison, debugging, and test management.
The document discusses various aspects of test management including organizational structures for testing, configuration management, test estimation and monitoring, incident management, and standards for testing. It describes different levels of independence for testing, such as testing by developers, testing by development teams, and independent test teams. It also outlines the importance of configuration management, estimating and measuring test progress, logging incidents, and following standards for quality assurance and industry-specific testing.
The document provides two drawing challenges that instruct players to draw various shapes, objects, and scenes within time limits. The first challenge gives 1 minute to draw a red square with green windows and door, a blue dog, triangle, flagpole, and seven birds on grass. The second challenge in 1.5 minutes is nearly identical but specifies a blue triangle, red dog, and eight birds, adding a flag with text from "Jabberwocky". Contact information is provided for the curator of the game.
The document provides an overview of dynamic testing techniques used in software testing. It discusses black box and white box testing approaches and some common techniques used, including equivalence partitioning, boundary value analysis, decision tables, statement coverage, and branch/decision coverage. The techniques help testers select test cases in a more systematic and thorough manner to effectively find software faults.
The document provides an overview of the agenda and content for Day 1 of an ISTQB Foundation Level training course. It begins with an introduction to ISTQB, including what it is, its purpose, and certification levels. It then outlines the agenda for Day 1, which includes introductions to ISTQB, principles of testing, testing throughout the software development lifecycle, static testing techniques, and tool support for testing. The document provides details on each of these topics, such as definitions of testing, principles of testing, software development models, testing levels, types of testing, and examples of static testing techniques.
O documento descreve o PhantomJS, um "browser" sem interface gráfica que roda no console e permite executar testes funcionais de JavaScript e acessar e manipular páginas web. Ele suporta padrões web como DOM, CSS e JSON e pode ser usado com frameworks de teste como Jasmine ou para integrar testes com Capybara no Ruby.

6. Problem
Verilen değerler göz önüne alınarak, ulaşım maliyetinin en az olması
koşuluyla çelik rulo fabrikalarından otomobil fabrikalarına çelik rulo taşıma
planı nasıl olmalıdır?
7. Çözüm
Ulaşım maliyetinin en az olması istenildiği için, problemi minimum amaç
fonksiyonu olacak şekilde çözmeliyiz.
𝑚𝑖𝑛 𝑋𝑖𝑗𝐶𝑖𝑗𝑛
𝑗=1
𝑚
𝑖=1
13. Çözüm
Elimizde her çelik rulo üreticisi ve otomobil fabrikası için toplamda 10 tane
kısıt oldu. Eğer kısıtlara her bir değişken için negatif olmama koşulunu da
eklersek, elimizde ulaştırma problemi için lineer bir problem olmuş olur.
14. AMPL Çözüm Modeli
Ulaştırma problemimiz için bir çözüm modeli bulmamız gerekiyor.
Bunun için şu yolu izleyebiliriz. Elimizde iki tane ana nesne var. Birisi
kaynak yani çelik rulo üreten fabrikalar, diğeri ise ulaştırılması gereken
yerler yani çelik ruloları kullanacak otomobil üreticileri. Bunları iki ayrı
dizi olarak düşünebiliriz. Rulo üretici fabrikalara TEDARIK, bu ürünleri
kullanacak fabrikalara da TALEP dizisi olarak düşünebiliriz.
15. AMPL ile Çözüm Modeli
Bu durumda iki ana parametremizi şu şekilde gösterebiliriz;
param supply {TEDARIK} >= 0;
param demand {TALEP} >= 0;
Tedarik ve talep durumları için şöyle bir denklem yazabiliriz;
check: sum {i in TEDARIK} supply[i] = sum {j in TALEP} demand[j];
16. AMPL ile Çözüm Modeli
Bu denklemde belirtilen tedariklerin toplamı taleplerin toplamına eşit
olmak zorundadır. Bu koşul sağlanmadığı sürece olası bir çözüm mümkün
değildir.
Her talep ve arz kombinasyonu için bir ulaşım maliyeti ve ulaşım miktarını
sembolize eden bir değişkene ihtiyacımız var. Bu koşulu da şu şekilde
gösterebiliriz.
param maliyet {TEDARIK, TALEP} >= 0;
var Trans {TEDARIK, TALEP} >= 0;
Her belirli TEDARIK i ve TALEP j için toplam maliyeti şu şekilde
gösterebiliriz.
Maliyet[i,j] * Trans[i,j]
17. AMPL ile Çözüm Modeli
Tüm bu denklem kümelerini bir şekilde gösterirsek amaç fonksiyonumuzu
şu şekilde gösterebiliriz:
minimize Toplam_Maliyet:
sum {i in TEDARIK, j in TALEP} maliyet[i,j] * Trans [i,j];
Aynı şekilde kısıtlarımızı gösterecek olursak;
Subject to Supply {i in TEDARIK } :
sum {j in TALEP} Trans[i,j] = supply[i];
Subject to Demand {j in TALEP}:
sum {i in TEDARIK} Trans[i,j] = demand[j];
18. AMPL Çözüm
Hazırladığımız bu modeli ampl ile çözdüğümüzde sonuç aşağıdaki gibidir.
Min: Z(x*) = 218800 dolar olarak bulduk.
