Jenkins + Webdriver Fehler + Chrom +

Question

Ich benutze Grunt mit Winkelmesser + Selen. Die Tests laufen auf MY-Rechner (Mac) perfekt auf Chrome und Firefox. Aber auf dem CENTOS 6.5 läuft es nicht für Chrome. Firefox funktioniert auf der CENTOS-Maschine. Wenn ich den Chromedriver aus der PATH-Variable entferne, bekomme ich den gleichen Fehler. Also weiß ich, dass es nicht der Chromedriver ist, der das Problem verursacht, weil ich es auch in der Winkelmesserkonfigurationsdatei angegeben habe. Woher weiß ich, ob es sich um ein Selen-Problem oder ein Chrom-Driver-Problem handelt? Ich mache eine "npm install" und habe den "chromedriver": "^ 2.21.2", "winkelmesser": "^ 3.3.0", "selen-server-standalone-jar": "^ 2.53.0", " webdriver-manager ":"^10.0.2 "in der package.json angegeben. Was ist das Problem beim Ausführen des Befehls grunt?

Der Fehler, den ich bekommen ist

grunt --ENV=qa --clientName=clientname --device=desktop e2e-test

Answer 1

Da der Server nicht über einen Display hat, müssen Sie Ihre Tests mit xvfb als virtuelles Display ausgeführt werden, so dass die Browser-Fenster wiedergegeben werden können.
