不在类路径中的依赖项的测试资源?
我有一个使用Maven设置的多模块Spring项目:
I have a multi module Spring project that I set up using Maven:
my-root (pom)
- my-logic
- my-webapp (depending on my-logic)
- my-consoleapp (depending on my-logic)
我的测试类继承自 AbstractTransactionalJUnit4SpringContextTests
并使用 @ContextCofiguration
用于设置 ApplicationContext
。
My Test classes inherit from AbstractTransactionalJUnit4SpringContextTests
and use @ContextCofiguration
for setting up the ApplicationContext
.
例如Spring Controller的测试类:
E.g. the test class for a Spring Controller:
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {
"classpath:applicationContext-logic-test.xml",
"classpath:applicationContext-web-test.xml"})
public class ControllerTest extends AbstractTransactionalJUnit4SpringContextTests {
@Autowired
private ApplicationContext applicationContext;
...
}
如你所见,有一个配置XML每个模块。我有单独的配置进行测试,驻留在每个模块的测试/资源中(另外还有后缀-test)。这一切都有效(类编译,运行和JUnit测试成功)如果我在Eclipse中运行JUnit测试。
As you can see there is a config XML per module. I have seperate configs for tesing, residing in test/resources of each module (and additionaly having the suffix "-test"). This all works (the class compiles, runs and the JUnit tests are successful) if I run the JUnit test in Eclipse.
现在我的问题:使用Maven运行测试不起作用!(例如在 my-root
上使用运行方式>Maven安装(我使用) m2eclipse的))。具体来说,它将引发以下异常:
Now to my problem: Running the test using Maven will NOT work! (e.g. with "Run As">"Maven install" on my-root
(I use m2eclipse)). Specifically, it will throw the following exception:
java.io.FileNotFoundException:类路径资源[applicationContext-logic-test.xml]不能因为它不存在而被打开`
java.io.FileNotFoundException: class path resource [applicationContext-logic-test.xml] cannot be opened because it does not exist`
似乎Maven没有添加来自 my-logic的文件/ src / test / resources
到运行 my-webapp
的单元测试时设置的类路径。
It seems that Maven does not add the files from my-logic/src/test/resources
to the classpath that is set up when running the unit tests of my-webapp
.
我该如何解决这个问题?
How can I fix that?
似乎Maven不会将
my-logic / src / test / resources
中的文件添加到运行my-webapp的单元测试时设置的类路径中。
It seems that Maven does not add the files from
my-logic/src/test/resources
to the classpath that is set up when running the unit tests of my-webapp.
不,确实没有。首先,Maven使用始终通过本地存储库解析的二进制依赖项。第二,二进制依赖项不包括测试内容。
No, indeed, it doesn't. First, Maven uses binary dependencies that are always resolved through the local repository. And second, binary dependencies don't include test stuff.
但你可以做的是:
- 配置
my-logic
模块,使用jar:test-jar
- 配置
my-webapp
模块以依赖此测试JAR(使用test
范围)。
- configure the
my-logic
module to create a test JAR usingjar:test-jar
- configure the
my-webapp
module to depend on this test JAR (using atest
scope).
对于#1,你必须在 my-logic的pom.xml中配置Maven Jar插件
:
<project>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.2</version>
<executions>
<execution>
<goals>
<goal>test-jar</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
</project>
Maven将创建一个内容为 target / test-classes的JAR
在包期间
并安装/部署它。
And Maven will create a JAR with the content of target/test-classes
during package
and install / deploy it.
对于#2,声明一个依赖项在 my-webapp
的pom.xml中的测试JAR上:
For #2, declare a dependency on the test JAR in the pom.xml of my-webapp
:
<project>
...
<dependencies>
<dependency>
<groupId>com.myco.app</groupId>
<artifactId>foo</artifactId>
<version>1.0-SNAPSHOT</version>
<type>test-jar</type>
<scope>test</scope>
</dependency>
</dependencies>
...
</project>
应该这样做。
