一、stub unit test
“test stub”命令创建JUnit测试
1、假定已经创建service层代码
package org.rooina.coursemanager.service;
import java.math.BigDecimal;
import org.springframework.beans.factory.annotation.Autowired;
public class DefaultTaxCalcService implements TaxCalcService {
private BigDecimal taxRate;
@Autowired
public DefaultTaxCalcService(BigDecimal taxRate) {
this.taxRate = taxRate;
}
@Override
public BigDecimal calculateTax(BigDecimal price) {
return price.multiply(taxRate);
}
}
2、创建测试脚本
roo> test stub --class ~.service.DefaultTaxService
3、产生测试代码
package org.rooina.coursemanager.service;
import org.junit.Test;
public class DefaultTaxCalcServiceTest {
private DefaultTaxCalcService defaultTaxCalcService = ➥
new DefaultTaxCalcService();
@Test
public void calculateTax() {
org.junit.Assert.assertTrue(true);
}
}
4、更新测试代码
package org.rooina.coursemanager.service;
import java.math.BigDecimal;
import junit.framework.Assert;
import org.junit.Test;
public class DefaultTaxCalcServiceTest {
private DefaultTaxCalcService defaultTaxCalcService =
new DefaultTaxCalcService(new BigDecimal("0.02"));
@Test
public void calculateTax() {
BigDecimal price = new BigDecimal("50");
BigDecimal taxAmount = defaultTaxCalcService.calculateTax(price);
Assert.assertEquals("Tax rate invalid",
new BigDecimal("1.00"), taxAmount);
}
}
二、任意测试
测试任意类时
1、脚本代码
roo> class --class ~.web.BillingServiceSystemTest ➥ --path SRC_TEST_JAVA
2、测试代码
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:/META-INF/spring/applicationContext*.xml")
public class TaskServiceSystemTest {
@Autowired
private TaskService service;
long studentId;
@Test
@Transactional
public void testTask() {
TaskDataOnDemand taskDod = new TaskDataOnDemand();
Task task = taskDod.getRandomTask();
Long taskId = task.getId();
Task task1 = service.findTask(taskId);
Assert.assertNotNull(task1);
}
}
