如何修复线程“main”java.lang.NullPointerException中的此错误异常 在newproject.PG1.main(PG1.java:30)中,我相信它是关于getTitle方法的,但我不知道如何更正它“线程中的异常”;“主要”;newproject.PG1.main处的java.lang.NullPointerException(PG1.java:30),java,Java,如何修复线程“main”java.lang.NullPointerException中的此错误异常 在newproject.PG1.main(PG1.java:30)中,我相信它是关于getTitle方法的,但我不知道如何更正它 My code is below package newproject; import org.openqa.selenium.firefox.FirefoxDriver; //comment the above line and uncomment below li

driver.get(baseUrl);
// get the actual value of the title

* the result as "Passed" or "Failed"
*/
if (actualTitle.contentEquals(expectedTitle)){
System.out.println("Test Passed!");
} else {
System.out.println("Test Failed");
}
//close Fire fox
driver.close();
}
}
actualTitle
为空-尝试与if语句部分相反,而不是actualTitle.contentEquals(expectedTitle)
doexpectedTitle.contentEquals(actualTitle)
,这将不会生成NPE。哪一行是第30行?如果是由driver.getTitle()生成的,你可能想查看这个链接。你能写完整的stackTrace吗?我很乐意听到其他解释。为什么投票被否决?这几乎肯定是对所问问题的正确答案。
