Question

我已编写参数化测试用例。当我通过蚂蚁运行它时，我没有得到理想的结果。如果没有Parameterized，测试用例将按需运行。请告诉我我错在哪里以及我需要做出哪些改变。

代码：

import java.util.Arrays;
import java.util.Collection;
import junit.framework.TestCase;
import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.junit.runners.Parameterized;
import org.junit.runners.Parameterized.Parameters;

@RunWith(value = Parameterized.class)
public class HelloWorldTest extends TestCase {

    int num1;
    int num2;
    int num3;

    public HelloWorldTest(int num1, int num2, int num3) {
        super();
        this.num1 = num1;
        this.num2 = num2;
        this.num3 = num3;
    }

    @Parameters
    public static Collection<Object[]> data() {
        Object[][] data = new Object[][] { { 1, 1, 2 }, { 2, 2, 5 } };
        return Arrays.asList(data);
    }

    @Test
    public void testSummationPositive() {
        Assert.assertEquals(num1 + num2, num3);
    }

}

Ant脚本：

            </manifest>
        </jar>
    </target>

    <target name="run" depends="jar,junit">

            </batchtest>

    <target name="main" depends="clean,run" />

由于您使用的是JUnit 4，因此不需要extends TestCase声明。尝试删除它，看看你的测试是否正常运行。

如何为参数化的jUnit测试用例编写ant脚本？
