我正在尝试使用命令提示符和以下命令编译我的 java 文件check4PrimeTest.java":
I'm trying to compile my java file 'check4PrimeTest.java' using the command prompt with the following command:
javac -classpath .:junit.jar check4PrimeTest.java
javac -classpath .:junit.jar check4PrimeTest.java
我收到以下错误:
错误:包 junit.framework 不存在 import junit.framework.*;
error: package junit.framework does not exist import junit.framework.*;
我不知道为什么会出现这个错误,因为我的程序中有 import junit.framework.*.
I'm not sure why i get this error as i have import junit.framework.* in my program.
下面是我的代码:
package check4prime; // check4PrimeTest.java //Imports import junit.framework.*; public class check4PrimeTest extends TestCase { //Initialize a class to work with. private check4Prime check4prime = new check4Prime(); //constructor public check4PrimeTest (String name) { super(name); } //Main entry point public static void main(String[] args) { System.out.println("Starting test..."); junit.textui.TestRunner.run(suite()); System.out.println("Test finished..."); } // end main() //Test case 1 public void testCheckPrime_true() { assertTrue(check4prime.primeCheck(3)); } //Test cases 2,3 public void testCheckPrime_false() { assertFalse(check4prime.primeCheck(0)); assertFalse(check4prime.primeCheck(1000)); } //Test case 7 public void testCheck4Prime_checkArgs_char_input() { try { String [] args= new String[1]; args[0]="r"; check4prime.checkArgs(args); fail("Should raise an Exception."); } catch (Exception success) { //successful test } } //end testCheck4Prime_checkArgs_char_input() //Test case 5 public void testCheck4Prime_checkArgs_above_upper_bound() { try { String [] args= new String[1]; args[0]="10001"; check4prime.checkArgs(args); fail("Should raise an Exception."); } catch (Exception success) { //successful test } } // end testCheck4Prime_checkArgs_upper_bound() //Test case 4 public void testCheck4Prime_checkArgs_neg_input() { try { String [] args= new String[1]; args[0]="-1"; check4prime.checkArgs(args); fail("Should raise an Exception."); } catch (Exception success) { //successful test } } // end testCheck4Prime_checkArgs_neg_input() //Test case 6 public void testCheck4Prime_checkArgs_2_inputs() { try { String [] args= new String[2]; args[0]="5"; args[1]="99"; check4prime.checkArgs(args); fail("Should raise an Exception."); } catch (Exception success) { //successful test } } // end testCheck4Prime_checkArgs_2_inputs //Test case 8 public void testCheck4Prime_checkArgs_0_inputs() { try { String [] args= new String[0]; check4prime.checkArgs(args); fail("Should raise an Exception."); } catch (Exception success) { //successful test } } // end testCheck4Prime_checkArgs_0_inputs //JUnit required method. public static Test suite() { TestSuite suite = new TestSuite(check4PrimeTest.class); return suite; } //end suite() } //end check4PrimeTest 推荐答案您收到此错误是因为您在尝试导入包时未告知系统包所在的位置.以下是告诉您的系统包所在位置的说明:
You are getting this error because you're trying to import a package without telling your system where the package is located. Here are instructions on telling your system where the package is located:
您的 javac 目标除了源和目标目录 - 它不添加任何类路径条目;你需要为相应的 JUnit jar 文件添加一个条目.查看 javac 任务文档了解更多详情.您可能想要指定路径JUnit 作为类路径属性、嵌套元素或对在别处声明的路径.
Your javac target doesn't specify anything apart from the source and target directory - it doesn't add any classpath entries; you'll need to add an entry for the appropriate JUnit jar file. See the javac task documentation for more details. You may want to specify the path to JUnit as a classpath attribute, a nested element, or a reference to a path declared elsewhere.
