运行来自命令行的 junit class 文件

Question

我从命令行尝试运行一个 junit class 文件，我收到以下错误：

 D:\saurabh>java -cp D:\testing\selenium_scripts\junit-4.4.jar org.junit.runner.JUnitCore D:\saurabh\NewMercury.class
JUnit version 4.4
Could not find class: D:\saurabh\NewMercury.class

Time: 0

OK (0 tests)


D:\saurabh>dir /p
 Volume in drive D has no label.
 Volume Serial Number is 4C6B-63F6

 Directory of D:\saurabh

06/24/2015  06:09 PM    <DIR>          .
06/24/2015  06:09 PM    <DIR>          ..

03/11/2015  07:32 PM           148,696 PortQryV2.exe

class 文件存在，但仍然显示错误 "Could not find class: D:\saurabh\NewMercury.class"

Answer 1

D:\saurabh\NewMercury.class 无效方式.

从 D:\saurabh 目录执行的正确命令是：

D:\saurabh>java -cp .;D:\testing\selenium_scripts\junit-4.4.jar org.junit.runner.JUnitCore NewMercury

现在如果你是运行命令：

C:\Users2720\workspace\Test\bin\com\tests>java -cp .;D:\testing\selenium_scri pts\junit-4.4.jar org.junit.runner.JUnitCore NewMercury

运行如下： C:\Users2720\workspace\Test\bin>java -cp .;D:\testing\selenium_scripts\junit-4.4.jar org.junit.runner.JUnitCore com.tests.NewMercury

//运行ning junit test(命令行)格式：

java -cp .;path_to_junit_jar\junit-4.4.jar org.junit.runner.JUnitCore you_class_with_package
path_to_junit_jar - D:\testing\selenium_scri分
you_class_with_package - com.tests.NewMercury 即考虑到 NewMercury.java 有一个声明 "package com.tests"

Answer 2

我前进了一点，但仍然面临这个问题：这是原始的 class 文件，它在 eclipse

中运行良好

C:\Users2720\workspace\Test\bin\com\tests>java -cp .;D:\testing\selenium_scri
pts\junit-4.4.jar org.junit.runner.JUnitCore NewMercury

Answer 3

这是 NewMercury.java 的代码：

package com.tests;

import java.util.concurrent.TimeUnit;
import org.junit.*;
import static org.junit.Assert.*;
import org.openqa.selenium.*;
import org.openqa.selenium.firefox.FirefoxDriver;

public class NewMercury {
  private WebDriver driver;
  private String baseUrl;
  private boolean acceptNextAlert = true;
  private StringBuffer verificationErrors = new StringBuffer();

  @Before
  public void setUp() throws Exception {
    driver = new FirefoxDriver();
    baseUrl = "http://www.google.co.in";
    driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
  }

  @Test
  public void testNewMercury() throws Exception {
    driver.get(baseUrl + "/");
    driver.findElement(By.id("lst-ib")).clear();
    driver.findElement(By.id("lst-ib")).sendKeys("mercury travels");
    driver.findElement(By.linkText("Mercury Travels: Flight, Cheap Air Tickets , Hotels, Holiday ...")).click();
  }

  @After
  public void tearDown() throws Exception {
    driver.quit();
    String verificationErrorString = verificationErrors.toString();
    if (!"".equals(verificationErrorString)) {
      fail(verificationErrorString);
    }
  }

  private boolean isElementPresent(By by) {
    try {
      driver.findElement(by);
      return true;
    } catch (NoSuchElementException e) {
      return false;
    }
  }

  private boolean isAlertPresent() {
    try {
      driver.switchTo().alert();
      return true;
    } catch (NoAlertPresentException e) {
      return false;
    }
  }

  private String closeAlertAndGetItsText() {
    try {
      Alert alert = driver.switchTo().alert();
      String alertText = alert.getText();
      if (acceptNextAlert) {
        alert.accept();
      } else {
        alert.dismiss();
      }
      return alertText;
    } finally {
      acceptNextAlert = true;
    }
  }
}
