Protocol conformance
Verification
Scope
Replies to execute, complete, is_complete, and kernel_info requests, and the stdout, stderr, execute-result, display-data, and error output of each sample. Every message validated against the Jupyter messaging protocol v5 schema.
References
- Reference
- jupyter_kernel_test 0.7.0, Jupyter messaging protocol 5.x
- Versions
- PHP 8.5.10, Python 3.14.7, ipykernel 7.4.0, jupyter_client 8.10.0, jupyter_kernel_test 0.7.0
Data
- Inputs
- PHP samples declared on JuphyterKernelTests, tests/Protocol/test_kernel.py
Method
jupyter_kernel_test's KernelTests drive a kernel registered from the tested commit through jupyter_client, with the PHP samples declared in tests/Protocol/test_kernel.py.
- Check
- Comparison with a reference implementation
