TestContextAotGenerator now uses AotTestMappingsCodeGenerator to
generate a AotTestMappings__Generated.java class which is loaded in
AotTestMappings via reflection in order to retrieve access to
ApplicationContextIntializers generated during AOT processing.
Furthermore, the processAheadOfTimeAndGenerateAotTestMappings() method
in TestContextAotGeneratorTests now performs a rather extensive test
including:
- emulating TestClassScanner to find test classes
- processing all test classes and generating ApplicationContextIntializers
- generating mappings for AotTestMappings
- compiling all generated code
- loading AotTestMappings
- using AotTestMappings to instantiate the generated ApplicationContextIntializer
- using the AotContextLoader API to load the AOT-optimized ApplicationContext
- asserting the behavior of the loaded ApplicationContext
