我尝试在测试中执行多个断言,JUnit在第一个失败的断言处停止。
为了能够进行所有断言并在最后列出失败的断言,我使用了类ErrorCollector
和JUnit的@Rule
批注。
这是一个测试类的例子:
public class MovieResponseTest {
/**
* Enable a test not to stop on an error by doing all assertions and listing the failed ones at the end.
* the <code>@Rule</code> annotation offers a generic way to add extended features on a test method
*/
@Rule
public ErrorCollector collector = new ErrorCollector();
/**
* A test case for <code>setCelebrity</code> Method
* @see MovieResponse#setCelebrities(List)
*/
@Test
public void testSetCelebrities() {
// Some code
this.collector.checkThat("The size of cast list should be 1.", this.movieResponse.getCast(), hasSize(1));
this.collector.checkThat("The size of directors list should be 1.", this.movieResponse.getDirectors(), hasSize(1));
this.collector.checkThat("The size of writers list should be 1.", this.movieResponse.getWriters(), hasSize(1));
}
}
现在,我有一个带有多个断言的方法的类。有什么方法可以使
@Rule
通用,所以我不必在每个测试类中都写public ErrorCollector collector = new ErrorCollector();
。 最佳答案
创建一个抽象类,将ErrorCollector放入其中,并使所有测试类扩展该抽象类。
public abstract class UnitTestErrorController {
// Abstract class which has the rule.
@Rule
public ErrorCollector collector = new ErrorCollector();
}
public class CelebrityTest extends UnitTestErrorController {
// Whenever a failed test takes places, ErrorCollector handle it.
}
public class NormalPeopleTest extends UnitTestErrorController {
// Whenever a failed test takes places, ErrorCollector handle it.
}
