Run Python Tests Skill

Run end-to-end Python tests after making changes to verify correctness.

Arguments

• No arguments: Run all Python tests
• <filename>: Run all Python tests in the specified file
• <filename>:<test_name>: Run a specific Python test in the specified file

Arguments provided: $ARGUMENTS

Instructions

Test Timeout

Some tests take longer to run than others. The TEST_TIMEOUT parameter controls how long each test is allowed to run before being terminated.

• Quick verification (preferred): Pass TEST_TIMEOUT=20 to get fast feedback. Tests that exceed this timeout will be terminated.
• Full test run: Omit TEST_TIMEOUT to let tests run with the default timeout (300 seconds).

Always start with a quick verification, using TEST_TIMEOUT=20. Faster feedback loops lead to faster iteration.

If there are timeouts during a quick verification run, check if the timed-out tests are relevant to the current task:

• If you can determine relevance autonomously (e.g., the test name clearly relates to the code you changed), re-run those specific tests without a timeout.
• If you cannot determine relevance, ask the user whether the timed-out tests should be re-run without a timeout.

All Tests

./build.sh RUN_PYTEST ENABLE_ASSERT=1 TEST_TIMEOUT=20

All Tests From A Specific File

./build.sh RUN_PYTEST ENABLE_ASSERT=1 TEST_TIMEOUT=20 TEST="<filename without extension>"

For example:

./build.sh RUN_PYTEST ENABLE_ASSERT=1 TEST_TIMEOUT=20 TEST="test_crash"

for running tests from tests/pytests/test_crash.py.

All Tests From Multiple Files

./build.sh RUN_PYTEST ENABLE_ASSERT=1 TEST_TIMEOUT=20 TEST="<filename 1> <filename 2>"

For example:

./build.sh RUN_PYTEST ENABLE_ASSERT=1 TEST_TIMEOUT=20 TEST="test_crash test_gc"

for running tests from tests/pytests/test_crash.py and tests/pytests/test_gc.py.

Specific Test From A Specific File

./build.sh RUN_PYTEST ENABLE_ASSERT=1 TEST_TIMEOUT=20 TEST="<filename without extension>:<test_name>"

For example:

./build.sh RUN_PYTEST ENABLE_ASSERT=1 TEST_TIMEOUT=20 TEST="test_crash:test_query_thread_crash"

for running the test_query_thread_crash test from tests/pytests/test_crash.py.

Interpreting The Test Output

For each failed test, you'll see an error message with details about the failure, as seen from the Python test runner. Each failed test will also have an associated log file, located under tests/pytests/logs. The name of the log file changes with every test run, but it's included in the output of the test runner.

Report

After running the tests, put together a report:

• Number of tests passed
• Number of tests failed
• Number of tests skipped
• For each failing test:
  • The error message reported in the test output, on the Python side
  • The stack trace from the server logs for the Redis server:
    • If the panic is in Rust code, include the Rust panic message and the Rust backtrace (from the # search_rust_backtrace section)
    • If the crash is in C code, include just the C backtrace.
  • Path to the log file, relative to the root of the repository
