Automation is the technology by which a process or procedure is performed with minimum human assistance. Automation  or automatic control is the use of various control systems for operating equipment such as machinery, processes in factories, boilers and heat treating ovens, switching on telephone networks, steering and stabilization of ships, aircraft and other applications and vehicles with minimal or reduced human intervention. Some processes have been completely automated.
Afin de profiter au mieux de l’automatisation des tests, voici huit recommandations issues de notre expérience, acquise au cours de plus de 50 projets internationaux d’automatisation des tests en entreprise. Ces conseils sont destinés à aider l’amélioration du retour sur investissement en automatisation de tests et à améliorer la qualité logicielle.
The Obama White House has pointed out that every 3 months "about 6 percent of jobs in the economy are destroyed by shrinking or closing businesses, while a slightly larger percentage of jobs are added". A recent MIT economics study of automation in the United States from 1990 to 2007 found that there may be a negative impact on employment and wages when robots are introduced to an industry. When one robot is added per one thousand workers, the employment to population ratio decreases between 0.18–0.34 percentages and wages are reduced by 0.25–0.5 percentage points. During the time period studied, the US did not have many robots in the economy which restricts the impact of automation. However, automation is expected to triple (conservative estimate) or quadruple (generous estimate) leading these numbers to become substantially higher.
Sectional electric drives were developed using control theory. Sectional electric drives are used on different sections of a machine where a precise differential must be maintained between the sections. In steel rolling, the metal elongates as it passes through pairs of rollers, which must run at successively faster speeds. In paper making the paper sheet shrinks as it passes around steam heated drying arranged in groups, which must run at successively slower speeds. The first application of a sectional electric drive was on a paper machine in 1919. One of the most important developments in the steel industry during the 20th century was continuous wide strip rolling, developed by Armco in 1928.
Des méthodes peuvent s'appliquer à ces sélecteurs, notamment send_keys (pour écrire du texte sur la balise sélectionnée, bien évidemment si ce n'est pas une balise type input ou contenteditable, cela n'écrira rien), ou encore click (pour cliquer sur la balise). Pour naviguer sur une page, la méthode .get(URL) suffira. Toutes ces méthodes et ces sélecteurs s'appliqueront au driver (donc à notre navigateur PhantomJS qui tourne en tâche de fond)
An early development of sequential control was relay logic, by which electrical relays engage electrical contacts which either start or interrupt power to a device. Relays were first used in telegraph networks before being developed for controlling other devices, such as when starting and stopping industrial-sized electric motors or opening and closing solenoid valves. Using relays for control purposes allowed event-driven control, where actions could be triggered out of sequence, in response to external events. These were more flexible in their response than the rigid single-sequence cam timers. More complicated examples involved maintaining safe sequences for devices such as swing bridge controls, where a lock bolt needed to be disengaged before the bridge could be moved, and the lock bolt could not be released until the safety gates had already been closed.
Eléments essentiels de votre politique de qualité, les automates de tests permettent la robotisation de vos cas de tests. Ils sont notamment très utiles pour les tests de non régression qui doivent être répétés à chaque nouvelle version d’un logiciel. Quels sont les principaux automates disponibles sur le marché ? Quels sont leurs points forts ? Tour d’horizon.
I’ve used other automation tools besides VBA. Ubot and iMacros are both excellent, and powerful programs (their own programming languages, really). In some respects they’re easier, and for 99% of web automation tasksg, you really can’t go wrong with either. But I got to where I only used VBA because my programming was getting into Windows API’s and command line calls (Visual Basic is tightly integrated with Windows), plus I often found myself using Excel alongside these programs anyway. I discovered there’s almost nothing VBA can’t do with automating Windows and Internet Explorer (even making IE appear as a different browser), and it seemed to me investing time learning Microsoft’s Visual Basic programming language just made more sense.
