What’s the reproducer doing? An extension defines some byte code transformations which apply to a test class.
The test uses a Junit 5 @TestTemplate for tests. At runtime, the version of the test that runs is the version which was transformed by the extension. However, the ContextProvider for the test template is initialised with the non-transformed version of the test class (this is the problem).
Note that QuarkusDevModeTest may not seem to be enough to show this issue, it may need a proper integration testing running in dev mode. (I had another issue which definitely did not show up in the QuarkusDevModeTest but did with mvn Quarkus:dev.)

To see the failure,
rm -rf integration-tests/src/test/resources-filtered/projects/bff/target && mvn clean install verify -DskipTests=false -DskipITs=false
To play with the failing test in more detail,
cd integration-tests/src/test/resources-filtered/projects/bff
mvn quarkus:dev
mvn verify also fails.
