假设我们有如下类。

package demo03;
public class BusinessService {
	private int max(int a, int b) {
		return a > b ? a : b;
	}
}

下面我们看看如何测试私有方法。

package demo03;
import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;
import org.powermock.reflect.Whitebox;
@RunWith(PowerMockRunner.class)
@PrepareForTest({ BusinessService.class })
public class BusinessServiceTest {
	@Test
	public void test() throws Exception {
		BusinessService businessService = new BusinessService();
		// 调用私有方法
		int max = Whitebox.invokeMethod(businessService, "max", 1, 2);
		// 验证
		Assert.assertTrue(2 == max);
	}
}
