ExternalResourceでテストコードのリファクタリングをしてみるサンプル

BaseTest.java

import org.junit.After;
import org.junit.Before;


public abstract class BaseTest {
	@Before
	public void setUp() throws Exception {
		// setup
	}

	@After
	public void tearDown() throws Exception {
		// teardown
	}
}

BaseTestResource1.java

import org.junit.rules.ExternalResource;


public class BaseTestResource extends ExternalResource{
	@Override
	protected void before() throws Throwable {
		// setup
	}

	@Override
	protected void after() {
		// teardown
	}

}

BaseTestResource7.java

public class BaseTestResource extends ExternalResource{
	@Override
	protected void before() throws Throwable {
		// setup
	}

	@Override
	protected void after() {
		// teardown
	}

	public String getPath(){
		return "";
	}

	public HttpServletRequest request;
}

SampleTest1.java

import org.junit.Test;


public class SampleTest {

	@Test
	public void someTest() throws Exception {
		// setup

		// exercise

		// verify

		// teardown
	}

}

SampleTest2.java

import org.junit.After;
import org.junit.Before;
import org.junit.Test;


public class SampleTest {
	@Before
	public void setUp() throws Exception {
		// setup
	}

	@After
	public void tearDown() throws Exception {
		// teardown
	}

	@Test
	public void someTest() throws Exception {
		// exercise

		// verify
	}

}

SampleTest4.java

import org.junit.Test;


public class SampleTest extends BaseTest{
	@Test
	public void someTest() throws Exception {
		// exercise

		// verify
	}

}

SampleTest5.java

import org.junit.Rule;
import org.junit.Test;


public class SampleTest{
	@Rule
	public BaseTestResource resource = new BaseTestResource();

	@Test
	public void someTest() throws Exception {
		// exercise

		// verify
	}

}

SampleTest6.java

import org.junit.Test;

public class SampleTest extends BaseTest{
	@Test
	public void someTest() throws Exception {
		// exercise
		String path = super.getPath();
		HttpServletRequest request = super.request;

		// verify
	}

}

SampleTest7.java

public class SampleTest{
	@Rule
	public BaseTestResource resource = new BaseTestResource();

	@Test
	public void someTest() throws Exception {
		// exercise
		String path = resource.getPath();
		HttpServletRequest request = resource.request;

		// verify
	}
