在JUnit中使用TestSuite时@Rule注释不起作用

Question

我有3个测试类如下:

package com.junittest.testcases;

Test3类:

import junit.framework.TestCase;

import org.junit.Ignore;
import org.junit.Rule;
import org.junit.Test;
import org.junit.rules.TestRule;
import annotations.DataSetRule;
import annotations.DataSets;
import com.junittest.test.MyClass;

public class Test3 extends TestCase{
    MyClass m = new MyClass();
    String group = "user";

    @Rule
    public TestRule dataSetRule = new DataSetRule();

    @Test
    public void test5() {
        System.out.println("In Test 5");
        //assertEquals(5, m.add(2,3));
    }

    @Test
    public void test6() throws Exception {
        org.junit.Assume.assumeTrue(group.equals("user"));
        System.out.println("In Test 6");
        //assertEquals(-2, m.sub(2,3));
    }

    @DataSets({"dataset","dataset1"})
    @Test
    public void test7() {
        System.out.println("In Test 7");
    }

    @Ignore
    @Test
    public void test8() {
        System.out.println("in test8");
    }
}

Test2类:

package com.junittest.testcases;

import org.junit.Test;

import singletons.SingletonClass;

import com.junittest.test.MyClass;

import junit.framework.TestCase;

public class Test2 extends TestCase{
MyClass m = new MyClass();
    public void setUp() {
        SingletonClass sc = SingletonClass.getInstance();
        System.out.println(SingletonClass.callCount);
    }

    @Test
    public void test3() {
        assertEquals(5, m.add(2,3));
    }

    @Test
    public void test4() {
        assertEquals(-2, m.sub(2,3));
    }
}

Test1类:

package com.junittest.testcases;

import org.junit.Test;

import singletons.SingletonClass;

import com.junittest.test.MyClass;

import junit.framework.TestCase;

public class Test1 extends TestCase{
    MyClass m = new MyClass();

    public void setUp() {
        SingletonClass sc = SingletonClass.getInstance();
        System.out.println(SingletonClass.callCount);
    }

    @Test
    public void test1() {
        assertEquals(4, m.add(2,3));
    }

    @Test
    public void test2() {
        assertEquals(-1, m.sub(2,3));
    }


}

还有一个TestSuite类:

package com.junittest.testcases;
import rules.SomeTest;
import singletons.SingletonClass;
import junit.framework.Test;
import junit.framework.TestSuite;

public class TestSuite1 {
    public static Test suite() {
        SingletonClass sc = SingletonClass.getInstance();
        System.out.println(SingletonClass.callCount);

        TestSuite suite = new TestSuite(TestSuite.class.getName());
        suite.addTestSuite(Test1.class);
        suite.addTestSuite(Test2.class);
        suite.addTestSuite(Test3.class);
        return suite;
    }
}

问题是它在从Eclipse中从JUnit运行TestSuite1类时忽略了Test3类中的@Rule标记,因此输出不是预期的.为什么忽略@Rule标记.有没有办法执行所有三种情况？

Answer 1

您正在混合使用JUnit 3(junit.framework.*)和JUnit 4(org.junit.*)代码.如果您仅使用JUnit 4,问题应该消失.

1. 删除extends TestCase(它们很简单,不需要,因为你的测试是用注释的@Test.
2. 将@Before注释添加到setUp()方法中.
3. 使用JUnit4的套件:https://github.com/junit-team/junit/wiki/Aggregating-tests-in-suites
