Restructure tests #14
Description
Having test projects that are specific to a particular logging system and test all DI framework adapters (e.g., loginject-test-log4j) is a problematic approach for a number of reasons. For example, Dagger and Dagger 2 use the same package name, so it is not possible to have both DI frameworks on the classpath at the same time. Also, in the DI-specific tests that are part of each DI adapter, there is a considerable amount of code duplication for setting up the test scenarios.
Ideas:
- Have a common project as a test dependency that contains all test scenarios (without bindings)
- Each DI adapter provides bindings for the test scenario
- Maybe introduce an abstraction to the various instantiation APIs, so that shared tests can be run for each DI adapter, provided that there is a binding and an instantiation adapter implementation
- The shared test scenario project could depend on all tested logging frameworks
- Utilize JUnit parameterized testing to support Cartesian product of (all DI adapters) x (all logging frameworks)
