#Overview
This directory contains scripts that facilitate building and running tests. We are using python scripts as entrypoint for our
tests because that gives us the opportunity to run tests using the same commandline regardless of the platform you are using.
#Unit tests (run_tests.py)
Builds gRPC in given language and runs unit tests. Use `tools/run_tests/run_tests.py --help` for more help.
######Example
`tools/run_tests/run_tests.py -l csharp -c dbg`
######Useful options (among many others)
- `--use_docker` Builds a docker container containing all the prerequisites for given language and runs the tests under that container.
- `--build_only` Only build, do not run the tests.
#Interop tests (run_interop_tests.py)
Runs tests for cross-platform/cross-language interoperability. For more details, see [Interop tests descriptions](/doc/interop-test-descriptions.md)
The script is also capable of running interop tests for grpc-java and grpc-go, using sources checked out alongside the ones of the grpc repository.
######Example
`tools/run_tests/run_interop_tests.py -l csharp -s c++ --use_docker` (run interop tests with C# client and C++ server)
#Performance benchmarks (run_performance_tests.py)
Runs predefined benchmark scenarios for given languages. Besides the simple configuration of running all the scenarios locally,
the script also supports orchestrating test runs with client and server running on different machines and uploading the results
to BigQuery.
######Example
`tools/run_tests/run_peformance_tests.py -l c++ node`
######Useful options
- `--regex` use regex to select particular scenarios to run.
#Stress tests (run_stress_tests.py)
Runs modified interop tests clients and servers under heavy load for an extended period of time to discover potential stability issues.
The tests are internally using Kubernetes to run the client and server on GKE and upload statistics to BigQuery.
`tools/run_tests/stress_test/run_on_gke.py --gcp_project_id=<google-cloud-platform-project-id> --config_file=<path-to-config-file>`
The directory `tools/run_tests/stress_test/configs/` contains the config files for several scenarios
#Artifacts & Packages (task_runner.py)
A generalized framework for running predefined tasks based on their labels. We use this to building binary artifacts & distrib packages and testing them)
######Example
`tools/run_tests/task_runner.py -f python artifact linux x64` (build tasks with labels `python`, `artifact`, `linux`, and `x64`)
