端到端测试部分

和端到端测试相关的make target

E2e测试的 target 定义在 dapr_tests.mk：

https://github.com/dapr/dapr/blob/master/tests/dapr_tests.mk

但因为内容比较独立，单独拿出来细看

变量定义

E2E_TEST_APPS 定义了要 e2e 测试要用到的app：

# E2E test app list
# e.g. E2E_TEST_APPS=hellodapr state service_invocation
E2E_TEST_APPS=actorjava \
actordotnet \
actorpython \
actorphp \
hellodapr \
stateapp \
secretapp \
service_invocation \
service_invocation_grpc \
service_invocation_grpc_proxy_client \
service_invocation_grpc_proxy_server \
binding_input \
binding_input_grpc \
binding_output \
pubsub-publisher \
pubsub-subscriber \
pubsub-subscriber_grpc \
pubsub-subscriber-routing \
pubsub-subscriber-routing_grpc \
actorapp \
actorclientapp \
actorfeatures \
actorinvocationapp \
actorreentrancy \
runtime \
runtime_init \
middleware \
job-publisher \

E2E_TESTAPP_DIR 是 e2e 测试应用所在的目录：

# E2E test app root directory
E2E_TESTAPP_DIR=./tests/apps
