假设我们有如下类。

package demo06;

public class BusinessService {
	private String serviceName = "";
	
	public BusinessService (String serviceName) {
		this.serviceName = serviceName;
	}

	public String getServiceName() {
		return serviceName;
	} 
	
}

下面我们看看如何不调用构造函数创建对象。

package demo06;

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 {
		// 不调用构造函数
		BusinessService businessService = Whitebox.newInstance(BusinessService.class);

		// 验证
		Assert.assertNull(businessService.getServiceName());
	}

}
