By default Maven will not run the test with the Jupiter engine as
In order to have Maven Surefire run any tests at all, a TestEngine implementation must be added to the runtime classpath.
And this is not present by default.
So to enable it you have to configure the maven-surefire-plugin that runs the unit tests as documented in the Jupiter documentation :
UPDATE (28.10.2020):
Since version 2.22.0, you only have to specify a test dependency on the desired junit engine. Failing to do so, will also result in the behavior described in the question.
<dependencies>
<dependency>
<groupId>org.junit.jupiter</groupId>
<artifactId>junit-jupiter-engine</artifactId>
<version>5.4.0</version>
<scope>test</scope>
</dependency>
</dependencies>
Keeping the original answer as a reference, before version 2.22.0 the solution was:
<build>
<plugins>
<plugin>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.21.0</version>
<dependencies>
<dependency>
<groupId>org.junit.platform</groupId>
<artifactId>junit-platform-surefire-provider</artifactId>
<version>1.2.0</version>
</dependency>
<dependency>
<groupId>org.junit.jupiter</groupId>
<artifactId>junit-jupiter-engine</artifactId>
<version>5.2.0</version>
</dependency>
</dependencies>
</plugin>
</plugins>
</build>
Whatever the issue is not necessarily easy to spot because Maven uses a runner that is able to run the Jupiter tests but didn't manage to execute the hook methods...
As a hint : to know whether the JUnit 5 runner is launched you can execute the tests with the verbose flag such as : mvn test -X
.
If the Jupiter runner is used, you should find lines that look like :
[DEBUG] Surefire report directory: ...\target\surefire-reports
[DEBUG] Using configured provider org.junit.platform.surefire.provider.JUnitPlatformProvider

One of the most challenging things to do is ‘making the right choice.’ Arriving at a decision becomes even more complicated when there are multiple options in front of you☺. The same is the case with choosing a testing framework for .NET Core. The three major C# Unit testing frameworks are MSTest, NUnit, and xUnit.Net. You should select the most appropriate test framework that suits your project requirements. In this blog, we will see a detailed comparison between NUnit vs. XUnit vs. MSTest.
Collaboration is pivotal for any successful release. Can you imagine going through a sprint without consulting or informing any other team involved in the project about what you did? You can’t right because it is not a pretty picture. Modern SDLCs demand various teams to coordinate as they try to deliver a product as quickly as possible in the market, with assured quality.

There are many debates going on whether testers should know programming languages or not. Everyone has his own way of backing the statement. But when I went on a deep research into it, I figured out that no matter what, along with soft skills, testers must know some programming languages as well. Especially those that are popular in running automation tests.
LambdaTest also has a detailed JUnit tutorial explaining its features, importance, advanced use cases, best practices, and more to help you get started with running your automation testing scripts.
Here are the detailed JUnit testing chapters to help you get started:
