出现错误unhandled inspector error: {"code":-32000,"message":"Cannot navigate to invalid URL"}

unhandled inspector error: {"code":-32000,"message":"Cannot navigate to invalid URL"}这个错误的意思是：“未经处理的检查员错误：{“代码”：32000，“消息”：“无法定位到URL无效”}”

全部代码如下：

package cn.gloryroad;

import org.testng.annotations.Test;
import org.testng.annotations.BeforeMethod;
import org.openqa.selenium.By;
import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.testng.annotations.AfterMethod;

public class TestDemo2 {
    WebDriver driver;
    String baseUrl;
    JavascriptExecutor js;
  @Test
  public void testDataPicker() throws Exception {
      driver.get("baseUrl");
      WebElement textInputBox = driver.findElement(By.id("text"));
      setAttribute(driver,textInputBox,"value","文本框的文字和长度已经被修改了！");
      setAttribute(driver,textInputBox,"size","10");
      removeAttribute(driver,textInputBox,"size");
      
  }
  public void setAttribute(WebDriver driver,WebElement element,String attributeName,String value) {
      JavascriptExecutor js = (JavascriptExecutor) driver;
      js.executeScript("arguments[0].setAttribute(arguments[1],arguments[2]", element,attributeName,value);
  }
 
  public void removeAttribute(WebDriver driver,WebElement element,String attributeName) {
      JavascriptExecutor js = (JavascriptExecutor) driver;
      js.executeScript("arguments[0].removeAttribute(arguments[1],arguments[2]", element,attributeName);
  }
 
 
 
  @BeforeMethod
  public void beforeMethod() {
      baseUrl="http://localhost:8080/web/TestDataPicker.html";
      System.setProperty("webdriver.chrome.driver", "driver/chromedriver.exe");
      driver = new ChromeDriver();
  }

  @AfterMethod
  public void afterMethod() {
      driver.quit();
  }

}

把driver.get("baseUrl");放到beforemethod方法中就解决了
