Enfin, à vos premières exécutions et dans la mesure du possible, vérifiez visuellement ce qui se passe, quitte à mettre des points d'arrêt (breakpoint). Cela peut paraître bête, mais toutes les exceptions soulevées par les drivers ne sont pas toujours très explicites (voire inexistantes mais c'est parfois justifié !). Attention néanmoins au breakpoint, vous pouvez casser la synchronisation des événements, idem si vous prenez le focus sur la fenêtre du navigateur si vous êtes en local !
À travers nightwatch et de nombreux autres framework il est possible de jouer les tests via des solutions externes (EX : BrowserStack, SauceLabs). Cela offre de nombreuses combinaisons navigateurs/OS et permet de jouer les tests sur mobile sans effort supplémentaire. De plus, cela retire l’entretien des OS, navigateurs, VMs sur lesquels sont joués les tests.
Cette étape implique, en la présence effective des différents acteurs du projet, maîtrise d’œuvre et maîtrise d'ouvrage, le déroulement rigoureux de procédures de tests préalablement décrits, et l'identification de tout écart fonctionnel ou technique. C’est le client qui valide cette étape. On peut considérer une fonctionnalité vraiment terminée qu’une fois qu’elle a passé avec succès les tests d’acceptation.
The Defense Advanced Research Projects Agency (DARPA) started the research and development of automated visual surveillance and monitoring (VSAM) program, between 1997 and 1999, and airborne video surveillance (AVS) programs, from 1998 to 2002. Currently, there is a major effort underway in the vision community to develop a fully automated tracking surveillance system. Automated video surveillance monitors people and vehicles in real time within a busy environment. Existing automated surveillance systems are based on the environment they are primarily designed to observe, i.e., indoor, outdoor or airborne, the amount of sensors that the automated system can handle and the mobility of sensor, i.e., stationary camera vs. mobile camera. The purpose of a surveillance system is to record properties and trajectories of objects in a given area, generate warnings or notify designated authority in case of occurrence of particular events.[70]
In a typical hard wired motor start and stop circuit (called a control circuit) a motor is started by pushing a "Start" or "Run" button that activates a pair of electrical relays. The "lock-in" relay locks in contacts that keep the control circuit energized when the push button is released. (The start button is a normally open contact and the stop button is normally closed contact.) Another relay energizes a switch that powers the device that throws the motor starter switch (three sets of contacts for three phase industrial power) in the main power circuit. Large motors use high voltage and experience high in-rush current, making speed important in making and breaking contact. This can be dangerous for personnel and property with manual switches. The "lock in" contacts in the start circuit and the main power contacts for the motor are held engaged by their respective electromagnets until a "stop" or "off" button is pressed, which de-energizes the lock in relay.[10]
Starting in 1958, various systems based on solid-state[27][28] digital logic modules for hard-wired programmed logic controllers (the predecessors of programmable logic controllers (PLC)) emerged to replace electro-mechanical relay logic in industrial control systems for process control and automation, including early Telefunken/AEG Logistat, Siemens Simatic (de), Philips/Mullard/Valvo (de) Norbit, BBC Sigmatronic, ACEC Logacec, Akkord (de) Estacord, Krone Mibakron, Bistat, Datapac, Norlog, SSR, or Procontic systems.[27][29][30][31][32][33]
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.
