Cannot run test methods related with Neo4j in Spring Boot

[sngermiyanoglu]

Hi, I have a problem about running all tests regarding Neo4j in my Spring Boot App.

When I try to run any method of AppApplicationTests, I only see an infinite loop on the console and the method cannot work.

How can I fix it?

Here is the link : Test Class

I will just make a few notes that may help. Looking at one of my Junit 5 tests that uses a test container, I have the following: 

1. I have the Neo4JContainer variable annotated with '@Container'
2. I have the class using it annotated with '@Testcontainers'
3. I then create a Neo4j driver using the test container's Url

Is your test container getting spun up?  Also, you are auto wiring a driver into your test class. You need to use one pointing your test container. 

You don't get an exceptions? What behavior are you getting?

Here is my issue when I try to run any test method in AppApplicationTests

[glilienfield]

Can you post the entire trace stack.  Have you tried disabling all your test in this class and create one simple not that allow you go break to see if your test harness is coming up correctly? 

[sngermiyanoglu]

It is too long to share it here.

[glilienfield]

Then, can you include the enclosing exception above what you included, or as much as you are comfortable pasting?

The issue maybe related with this line defined in docker-compose .yml.

NEO4JLABS_PLUGINS: '["apoc"]'

I cannot detect it. I get this error shown below.

org.neo4j.driver.exceptions.ClientException: There is no procedure with the name `apoc.algo.dijkstra` registered for this database instance. Please ensure you've spelled the procedure name correctly and that the procedure is properly deployed.

Here is my error information shown below.

Please be aware that this is just a _debug_ message coming from the Docker java library. It has no impact on the testing.

For me setting also the password correct will run all tests (there is one failing but this is discussed in another thread)

@DynamicPropertySource
static void properties(DynamicPropertyRegistry registry) {
    registry.add("spring.neo4j.authentication.username", () -> "neo4j");
    registry.add("spring.neo4j.authentication.password", () -> container.getAdminPassword());
    registry.add("spring.neo4j.uri", () -> container.getBoltUrl());
}

The changes can be found in my fork https://github.com/meistermeier/SpringBootNeo4jShortestPath

I'll ask it in another thread but could you tell me where is the issue in a test class. I also added some test methods there.

Did you try upgrading to Neo4j 4.4.x as suggested by @koji in your other post?
