## Instructions for adding new language/runtimes
- Create new `Dockerfile.template`, `build_interop.sh.template` for the language/runtime under `template/tools/dockerfile/`.
- Run `tools/buildgen/generate_projects.sh` to create corresponding files under `tools/dockerfile/`.
- Add language/runtimes to `client_matrix.py` following existing language/runtimes examples.
- Run `tools/interop_matrix/create_matrix_images.py` which will build and upload images to GCR. Unless you are also building images for a gRPC release, make sure not to set `--release` (the default release 'master' is used for testing).
*: Please delete your docker images at https://pantheon.corp.google.com/gcr/images/grpc-testing?project=grpc-testing afterwards. Permissions to access GrpcTesting project is required for this step.
- Run `tools/interop_matrix/create_matrix_images.py` which will build (and upload) images to GCR.
## Instructions for creating new test cases
- Create test cases by running `LANG=<lang> [RELEASE=<release>] ./create_testcases.sh`. For example,

- `--release` specifies a git release tag. Defaults to `--release=all`. Make sure the GCR images with the tag have been created using `create_matrix_images.py` above.
- `--language` specifies a language. Defaults to `--language=all`.
For example, To test all languages for all gRPC releases across all runtimes, do `tools/interop_matrix/run_interop_matrix_test.py --release=all`.
- The output for all the test cases is recorded in a junit style xml file (default to 'report.xml').
- The output for all the test cases is recorded in a junit style xml file (defaults to 'report.xml').
## Instructions for running test cases against a GCR image manually
- Download docker image from GCR. For example: `gcloud docker -- pull gcr.io/grpc-testing/grpc_interop_go1.7:master`.
- Download docker image from GCR. For example: `gcloud docker -- pull gcr.io/grpc-testing/grpc_interop_go1.8:v1.16.0`.
- Run test cases by specifying `docker_image` variable inline with the test case script created above.
For example:
- `docker_image=gcr.io/grpc-testing/grpc_interop_go1.7:master ./testcases/go__master` will run go__master test cases against `go1.7` with gRPC release `master` docker image in GCR.
- `docker_image=gcr.io/grpc-testing/grpc_interop_go1.8:v1.16.0 ./testcases/go__master` will run go__master test cases against `go1.8` with gRPC release `v1.16.0` docker image in GCR.
Note:
- File path starting with `tools/` or `template/` are relative to the grpc repo root dir. File path starting with `./` are relative to current directory (`tools/interop_matrix`).
