grpc1.45.2/test/core/event_engine/test_suite/README.md

A reusable test suite for EventEngine implementations.

To exercise a custom EventEngine, create a new bazel test target that links against the //test/core/event_engine/test_suite:complete library, and provide a testing main function that sets a custom EventEngine factory.

Your custom test target will look something like:

grpc_cc_test(
    name = "my_custom_event_engine_test",
    srcs = ["my_custom_event_engine_test.cc"],
    uses_polling = False,
    deps = ["//test/core/event_engine/test_suite:complete"],
)

And the main function will be similar to:

#include "path/to/my_custom_event_engine.h"
#include "src/core/event_engine/test_suite/event_engine_test.h"

int main(int argc, char** argv) {
  testing::InitGoogleTest(&argc, argv);
  SetEventEngineFactory(
      []() { return absl::make_unique<MyCustomEventEngine>(); });
  auto result = RUN_ALL_TESTS();
  return result;
}

Alternatively, if you only want to exercise a subset of the conformance tests, you could depend on any subset of the following:

• //test/core/event_engine/test_suite:timer
• //test/core/event_engine/test_suite:dns
• //test/core/event_engine/test_suite:client
• //test/core/event_engine/test_suite:server
