This show mistake
MainPage --> WebDriverWait wait = new WebDriverWait(driver,
WAIT_TIME);
最佳答案
您需要初始化驱动程序
public class BaseTest {
protected WebDriver driver = new ChromeDriver();
driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
}
关于java - 如何通过 <init> 中的调用解决 webdriver 设置中的 NullPointerException？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/41207400/
