De cet effort, j’ai pu appliqué les mêmes mécanismes et fonctionnalités sur un autre produit similaire, en réutilisant une majeure partie du code en moins de 5 JP. La librairie de fonction étant extensible et réutilisable, la maintenance est simplifiée. L’intégration avec les différents outils de suivis d’anomalie est flexible car chacun dispose d’une librairie de fonction.
Likewise, a Feedback Control System is a system which tends to maintain a prescribed relationship of one system variable to another by comparing functions of these variables and using the difference as a means of control. The advanced type of automation that revolutionized manufacturing, aircraft, communications and other industries, is feedback control, which is usually continuous and involves taking measurements using a sensor and making calculated adjustments to keep the measured variable within a set range. The theoretical basis of closed loop automation is control theory.
Relay logic was introduced with factory electrification, which underwent rapid adaption from 1900 though the 1920s. Central electric power stations were also undergoing rapid growth and operation of new high pressure boilers, steam turbines and electrical substations created a large demand for instruments and controls. Central control rooms became common in the 1920s, but as late as the early 1930s, most process control was on-off. Operators typically monitored charts drawn by recorders that plotted data from instruments. To make corrections, operators manually opened or closed valves or turned switches on or off. Control rooms also used color coded lights to send signals to workers in the plant to manually make certain changes.
Zalenium est une extension de Selenium Grid permettant la mise en place locale et dynamique de plateformes de tests en utilisant des conteneurs Docker. Elle utilise Docker Sélénium pour exécuter des tests automatiques sur Firefox et Chrome localement, et redirige vers un fournisseur de tests cloud (Sauce Labs, BrowserStack, TestingBot) lorsqu’un script doit être exécuté sur un navigateur différent
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.
