代码:
public class Cadencie {
static WebDriver driver;
public void LoginCad(){
//System.setProperty("webdriver.firefox.bin", "C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe");
System.setProperty("webdriver.gecko.driver", "C:\\Program Files (x86)\\Mozilla Firefox\\geckodriver.exe");
driver = new FirefoxDriver();
driver.get("http://172.16.1.133:8090/CADENCIE/servlet/app");
try {
Thread.sleep(1000);
} catch(InterruptedException e){
e.printStackTrace();
}
Utilities.switchToWindow("Cadencie - User Logon [LOGON]", driver);
try{
Thread.sleep(2000);
} catch(InterruptedException e){
e.printStackTrace();
}
driver.findElement(By.id("idBANK")).clear();
driver.findElement(By.id("idBANK")).sendKeys("48");
driver.findElement(By.id("idEMPLOYEE")).clear();
driver.findElement(By.id("idEMPLOYEE")).sendKeys("200003");
driver.findElement(By.id("idPASSWORD")).clear();
driver.findElement(By.id("idPASSWORD")).sendKeys("Cadencie1");
driver.findElement(By.id("maintLOGON")).click();
driver.findElement(By.id("idPASSWORD")).clear();
driver.findElement(By.id("idPASSWORD")).sendKeys("Cadencie1");
driver.findElement(By.id("maint")).click();
}
我认为这可能是一个不一致的版本问题。因为我有另一个使用maven,selenium 2.52.0的自动化项目..但不确定这是否会导致问题。我这次不是在使用maven。只是尝试创建一个JAVA GUI程序(工具包)。
I think it might be an inconsistent version issue. Because I have another automation project which is using maven, selenium 2.52.0.. But not sure if this caused the problem. I'm not using maven this time. Just try to create a JAVA GUI program (tool kit).
推荐答案
异常是因为<$ c $中缺少jar文件c> classpath 。
如果您不使用Maven,请检查在MVN存储库页面编译依赖关系并手动将jar添加到类路径。
If you don't use Maven, check the Compile Dependencies at MVN Repository page and manually add the jars to your class path.
如果您使用的是Maven,请参阅: java.lang.classnotfoundexception:org.openqa。 selenium.io.Circular OutputStream
If you're using Maven, see: java.lang.classnotfoundexception: org.openqa.selenium.io.Circular OutputStream
