Question 1

How do I use Weld Testing Extensions with JUnit 5?

Accepted Answer

Use the @ExtendWith annotation with the WeldJunit5Extension, as detailed in the JUnit 5 README. This starts a CDI container and allows injection into test classes for seamless testing.

Question 2

Weld Testing Extensions vs Arquillian: which is better for CDI testing?

Accepted Answer

Weld Testing Extensions are lighter and ideal for unit/component testing with minimal setup, while Arquillian is better for integration tests with full deployments. Choose based on whether you need speed or broader environment simulation.

Question 3

How to add mock beans using Weld Testing Extensions and Mockito?

Accepted Answer

Define mock beans in your test class and use annotations like @EnableAutoWeld or custom configurations to include them. The README provides examples for combining with Mockito to replace real beans in the container.

Question 4

Does Weld Testing Extensions support the Jakarta namespace?

Accepted Answer

Yes, version 5.x and later support Weld 6.0 with the Jakarta namespace for CDI 4.1, as noted in the README warning. Ensure you use compatible versions for modern Java EE or Jakarta EE projects.

Question 5

Can I use Weld Testing Extensions with Kotlin?

Accepted Answer

It should work with Kotlin since it's a Java library, but you may need to handle CDI annotations carefully in Kotlin classes. Check the documentation for any compatibility issues or examples.

Question 6

What is the performance impact of using Weld Testing Extensions?

Accepted Answer

The main impact is from starting and stopping the CDI container per test run, which can slow down test suites. Optimizations are limited, so it's best for scenarios where accuracy outweighs speed.
