vanilla111 opened a new issue #3314:
URL: https://github.com/apache/incubator-dolphinscheduler/issues/3314
# Why "Failed to load ApplicationContext" when running tests locally
The first is the test command I ran:
```
mvn test -pl dolphinscheduler-server -Dtest
=TaskPriorityQueueConsumerTest#testSHELLTask
```
It should be noted that the above test is not the only one with this problem.
## The environment in which the problem occurs
The problem was originally discovered by running tests in IDEA, but also by
testing directly with the 'mvn' command.
- Operating system: MacOS
- JAVA: 1.8.0_111
- Maven: 3.5.2
- DS version: dev branch
To verify that it was a local environment problem, I created a new virtual
machine to test, which had the same problem.
- Operating system: CentOS 7
- JAVA: 1.8.0_221
- Maven: 3.6.3
- DS version: dev branch
## Action steps
I tested it on my virtual machine using the following steps:
```
git clone ...
cd incubator-dolphinscheduler-github/
git checkout dev
mvn clean install -pl dolphinscheduler-common -am -Dmaven.test.skip=true
mvn clean install -pl dolphinscheduler-dao -am -Dmaven.test.skip=true
mvn clean install -pl dolphinscheduler-service -am -Dmaven.test.skip=true
mvn clean install -pl dolphinscheduler-alert -am -Dmaven.test.skip=true
mvn test -pl dolphinscheduler-server
-Dtest=TaskPriorityQueueConsumerTest#testSHELLTask
```

## Problem analysis
According to my own knowledge, I tried to solve the above problems. Because
the reason is that `Autowired` errors, so I according to the prompt in the test
code
`dolphinscheduler-server/src/test/java/org/apache/dolphinscheduler/server/master/consumer/TaskPriorityQueueConsumerTest.java`,
To annotate `@ContextConfiguration` added a class
`CuratorZookeeperClient.class`, problem is solved.
Just like this:
```java
@ContextConfiguration(classes={DependencyConfig.class,
SpringApplicationContext.class, SpringZKServer.class,
NettyExecutorManager.class, ExecutorDispatcher.class,
ZookeeperRegistryCenter.class, TaskPriorityQueueConsumer.class,
ZookeeperNodeManager.class, ZookeeperCachedOperator.class,
ZookeeperConfig.class, MasterConfig.class,
CuratorZookeeperClient.class})
```
I mentioned this problem with more than one test code, but I'll summarize it
now:
> if the test code needs to Autowired class A objects, class A needs to
Autowired class B objects. Then `A.class` appears in the context configuration,
while `B.class` is not, an 'Failed to load ApplicationContext' exception will
appear and the test will fail.
## Question
Every time the project merges new code, it will be tested automatically. Why
is this test enough to pass without these problems?
