Does TestNG has runner like SpringJUnit4ClassRunner
提问by Micha? Mech
When I write tests in JUnit (in Spring context) I usualy do it like this:
当我在 JUnit 中（在 Spring 上下文中）编写测试时，我通常这样做：
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:testContext.xml")
public class SimpleTest {
@Test
public void testMethod() {
// execute test logic...
}
}
How can I do the same with TestNG?
我怎样才能用 TestNG 做同样的事情？
I'll add more details. With AbstractTestNGSpringContextTests it works, but not in a way I want to. I have some test ...
我会添加更多细节。使用 AbstractTestNGSpringContextTests 它可以工作，但不是我想要的方式。我有一些测试...
@ContextConfiguration(locations = { "classpath:applicationContextForTests.xml" })
public class ExampleTest extends AbstractTestNGSpringContextTests {
private Boolean someField;
@Autowired
private Boolean someBoolean;
@Test
public void testMethod() {
System.out.println(someField);
Assert.assertTrue(someField);
}
@Test
public void testMethodWithInjected() {
System.out.println(someBoolean);
Assert.assertTrue(someBoolean);
}
// setters&getters
}
and descriptor ...
和描述符...

That's why I asked about runner.
这就是我询问runner的原因。

TestNG does not use Spring to instantiate your test. That's why someField=null
TestNG 不使用 Spring 来实例化您的测试。这就是为什么 someField=null
回答by Klaus Groenbaek
Correct, TestNG always instantiates the Test class (put breakpoint in constructor to verify). Later (@BeforeClass) the beans from the context is injected into the Test class.
正确，TestNG 总是实例化 Test 类（在构造函数中放置断点以进行验证）。稍后（@BeforeClass）来自上下文的 bean 被注入到 Test 类中。
I'm however curious as to why you would every define the test as a bean in the first place. In the 10 years I have used Spring I have never needed to do that, or seen anyone do it...
但是，我很好奇为什么您首先将测试定义为 bean。在我使用 Spring 的 10 年中，我从未需要这样做，也从未见过任何人这样做......
