我正在为测试每个功能的 Spring 引导应用程序编写 cucumber-java 单元测试。当我与 spring boot 集成时,@Autowired 类抛出 NullPointer 异常。
Spring Boot 应用程序类,
@SpringBootApplication
public class SpringBootCucumberTest {
public static void main(String[] args) {
SpringApplication.run(SpringBootCucumberTest.class, args);
}
}
要测试的类,
@Component
public class Library {
private final List<BookVo> store = new ArrayList<BookVo>();
public void addBook(final BookVo BookVo) {
this.store.add(BookVo);
}
}
黄瓜单元类,
@RunWith(Cucumber.class)
@CucumberOptions(format = "pretty", features = "src/test/resources")
public class BookSearchTest {
}
黄瓜定义类,
public class BookSearchSteps extends AbstractDefinition{
@Autowired
private Library library;
private List<BookVo> result = new ArrayList<BookVo>();
@Given(".+book with the title '(.+)', written by '(.+)', published in (.+)")
public void addNewBook(final String title, final String author, @Format("dd MMMMM yyyy") final Date published) {
BookVo book = new BookVo(title, author, published);
library.addBook(book);
}
}
spring 与 cucumber 类的集成,
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = SpringBootCucumberTest.class, loader = SpringApplicationContextLoader.class)
@WebAppConfiguration
@IntegrationTest
public class AbstractDefinition {
public AbstractDefinition() {
}
}
如果定义类以这种方式工作,
public class BookSearchSteps extends AbstractDefinition{
private Library library = new Library();
private List<BookVo> result = new ArrayList<BookVo>();
@Given(".+book with the title '(.+)', written by '(.+)', published in (.+)")
public void addNewBook(final String title, final String author, @Format("dd MMMMM yyyy") final Date published) {
BookVo book = new BookVo(title, author, published);
library.addBook(book);
}
}
如果以这种方式定义类,则它不起作用,抛出 NullPointer 异常,
public class BookSearchSteps extends AbstractDefinition{
@Autowired
private Library library;
private List<BookVo> result = new ArrayList<BookVo>();
@Given(".+book with the title '(.+)', written by '(.+)', published in (.+)")
public void addNewBook(final String title, final String author, @Format("dd MMMMM yyyy") final Date published) {
BookVo book = new BookVo(title, author, published);
library.addBook(book);
}
}
@Autowired 在这个地方不起作用,我在运行测试时也看不到 Spring 启动应用程序日志。是集成springboot应用程序类进行黄瓜单元测试的正确方法。请建议我对此进行修复。
