Sergii Tkachenko 691a5fba87 [PSM Interop] Do not dump full Channel/Subchannel into logs (#33105 ) Before this change, `Found subchannel in state READY` and `Channel to xds:///psm-grpc-server:61404 transitioned to state ` would dump the full channel/subchannel, in some implementations that expose ChannelData.trace (f.e. go) would add 300 extra lines of log. Now we print a brief repr-like chanel/subchannel info: ``` Found subchannel in state READY: <Subchannel subchannel_id=9 target=10.110.1.44:8080 state=READY> Channel to xds:///psm-grpc-server:61404 transitioned to state READY: <Channel channel_id=2 target=xds:///psm-grpc-server:61404 state=READY> ``` Also while waiting for the channel, we log channel_id now too: ``` Waiting to report a READY channel to xds:///psm-grpc-server:61404 Server channel: <Channel channel_id=2 target=xds:///psm-grpc-server:61404 state=TRANSIENT_FAILURE> Server channel: <Channel channel_id=2 target=xds:///psm-grpc-server:61404 state=TRANSIENT_FAILURE> Server channel: <Channel channel_id=2 target=xds:///psm-grpc-server:61404 state=TRANSIENT_FAILURE> Server channel: <Channel channel_id=2 target=xds:///psm-grpc-server:61404 state=TRANSIENT_FAILURE> Server channel: <Channel channel_id=2 target=xds:///psm-grpc-server:61404 state=TRANSIENT_FAILURE> Server channel: <Channel channel_id=2 target=xds:///psm-grpc-server:61404 state=READY> ```		2 years ago

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 python -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.

Note: If you get an error such as ImportError: No module named httplib2, then you may be missing some Python modules. Install the module listed in the error and try again.

Note: some tests may be flaky. Check the "Issues" tab for known flakes and other issues.

The full suite of unit tests will take many minutes to run.

Interop tests (run_interop_tests.py)

Runs tests for cross-platform/cross-language interoperability. For more details, see Interop tests descriptions 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 python -s c++ --use_docker (run interop tests with C# client and C++ server)

Note: if you see an error like no space left on device when running the interop tests using Docker, make sure that Docker is building the image files in a location with sufficient disk space.

Performance benchmarks (run_performance_tests.py)

The run_performance_tests.py script is deprecated. See end-to-end benchmarking documentation for more info.

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)
