Tests of the underlying spawn/async functionality of Domain and Thread (not using STM.ml or Lin.ml which rely on them):

• domain/domain_joingraph.ml is a test of Domain's spawn/join based on a random dependency graph

• domain/domain_spawntree.ml is a test of Domain's spawn/join based on a random spawn tree

• thread/thread_joingraph.ml is a test of Thread's create/join based on a random dependency graph

• thread/thread_createtree.ml is a test of Thread's create/join based on a random create tree

Development tests

During development we use examples with known problems to help ensure that concurrency issues are indeed found as expected (aka. sanity check).

For Lin.Internal and Lin

• neg_tests/lin_internal_tests_common.ml and
• neg_tests/lin_tests_common.ml

contain "sanity check tests" for an unprotected global ref and a buggy concurrent list over unboxed int and boxed int64 types.

For STM

• neg_tests/stm_tests_spec_ref.ml and
• neg_tests/stm_tests_conclist.ml

contain similar tests.
