我是Java的初学者。我写了一个简单的程序,下面一个。但是我遇到编译错误。
Java类:
public class Return{
public static int fibonacci(int n){
if (n == 1 || n == 2){
return 1;
}
return fibonacci(n - 1) + fibonacci(n - 2);
}
public static void main(String[] args) {
System.out.println(fibonacci(6));
}
}
测试文件:
import junit.framework.TestCase;
public class ReturnTest extends TestCase{
public static void testFibonacci(){
assertEquals(1, Return.fibonacci(1));
assertEquals(1, Return.fibonacci(2));
assertEquals(1, Return.fibonacci(3));
}
public static void main(String[] args){
testFibonacci();
}
}
错误:
`ReturnTest.java:1: error: package junit.framework does not exist
import junit.framework.TestCase;
^
ReturnTest.java:3: error: cannot find symbol
public class ReturnTest extends TestCase{
^

5 errors`
我用Google搜索解决方案,但仍然停留在该错误上。所以请帮帮我。我现在该怎么办?
答案 0 :(得分:0)
您需要添加junit jar。找不到。
您可以从https://mvnrepository.com/artifact/junit/junit/4.11下载junit jar并下载jar
或者如果您正在使用maven,则将依赖项添加到pom中。
