IntelliJ 2020.3 problem with JUnit5

Hello, 

Please clarify the versions of the dependencies used and also please provide the little test sample the case is reproduced for you with. Thank you 

Sure - Running SpringBoot 2.4.0
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.4.0</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>

Other dependency versions:

<properties>
<java.version>15</java.version>
<model.mapper.version>2.3.8</model.mapper.version>
<maria.db.client.version>2.6.2</maria.db.client.version>
<junit.jupiter.version>5.6.2</junit.jupiter.version>
<testcontainers.version>1.15.0</testcontainers.version>
</properties>

All the unit/integration tests fail with the same error.
None of the test cases want to run.


To answer on a sample.

Unfortunately the issue is not reproduced on my side with the following dependencies and a simple test sample (provided below).

If possible can you please check if the problem is reproduced for you with my sample as well?

Please share your project sample here: https://uploads.services.jetbrains.com/

in case the issue occurs only with your data. Thank you

Have a look at the RestTemplateHandlerImplTest, AWSQueueMessageListenerITTest and ContactCreateMessageHandlerTest test classes.

The test runs fine with at cmd maven test:
Thank you for taking the time to help and sort this out.
Please enable the OAuth2 dependencies to compile.

Hello, 

Please clarify if the tests start running fine for you with IntelliJ IDEA 2020.3 if you comment out the exclusion part in dependencies?

Thank you 

Nope - unfortunately still the same problem.

Reloaded the project after compiling with cmd maven from a terminal session. Tried different build options.
Still failing with the same error.

PS - This happening to a couple of my other projects as well.
Works fine in 2020.2 but fails in 2020.3
