我正在編寫我的第一個junit測試類。我的calculator.java類在我的src目錄下,我的測試類(CalculatorTest.java)在test/src目錄下。我的問題是CalculatorTest類不能識別計算器類。有什麼想法嗎?這是在src目錄我calculator.java類:JUnit TestClass無法識別類
package edu.umb.cs.cs680.unittest;
public class Calculator {
public float multiply(float x, float y){
return x*y;
}
public float divide(float x, float y){
if(y==0){
throw new IllegalArgumentException("division by zero");
}
return x/y;
}
}
而且這是在測試/ src目錄我CalculatorTest類:
package edu.umb.cs.cs680.unittest;
import static org.junit.Assert.*;
import static org.hamcrest.CoreMatchers.*;
import org.junit.Test;
import edu.umb.cs.cs680.unittest.Calculator;
public class CalculatorTest{
@Test
public void multiply3By4(){
Calculator cut = new Calculator();
float expected = 12;
float actual = cut.multiply(3,4);
assertThat(actual, is(expected));
}
@Test
public void divide3By2(){
Calculator cut = new Calculator();
float expected = 1.5f;
float actual = cut.divide(3,2);
assertThat(actual, is(expected));
}
@Test(expected=IllegalArgumentException.class)
public void divide5By0(){
Calculator cut = new Calculator();
cut.divide(5,0);
}
}
這是我的build.xml:

這是錯誤:
cannot find symbol Calculator cut = new Calculator();
感謝
也許你的classpath存在缺陷。 –
你們兩個班是不同的包? –
