Seleniumをchromeで実行しようとするとInvocationTargetExceptionが発生する

[事象]

SeleniumIDE経由でChromeを用いてテストを行おうとすると、以下のスタックトレースの様なエラーが発生してテストができない。

[原因]

Seleniumのドライバを誤ってIEのドライバ名にしてしまっていた。。

 

[対応方法]

webdriver.ie.driverではなく、webdriver.chrome.driverに変更し実行すればすぐ動いた。

 変更前:java -jar selenium-server-standalone-2.48.2.jar -Dwebd
river.ie.driver=./IEDriverServer.exe

 変更後:java -jar selenium-server-standalone-2.48.2.jar -Dwebdriver.chrome.driver=./ChromeDriver.exe
