🛠️ Refactor suggestion
Enhance test robustness and clarity.
The test has several areas for improvement:
-
Redundant/confusing parameters: The test passes both a shell command
["sleep", "5"]and a data_dict with{"fn": sleep, "args": (5,)}, which seems redundant and potentially confusing. -
No verification of subprocess startup: The test immediately terminates without verifying the subprocess actually started.
-
Potential race condition: Immediate termination might not test the intended behavior if the subprocess hasn't fully started.
Consider this improved version:
def test_execute_in_subprocess(self):
+ import time
process = execute_in_subprocess(
- command=["sleep", "5"],
+ command=["python", "-c", "import time; time.sleep(5)"],
file_name="test.h5",
- data_dict={"fn": sleep, "args": (5,)},
+ data_dict={"fn": sleep, "args": (5,)},
)
+ # Give the subprocess a moment to start
+ time.sleep(0.1)
+ # Verify process is running before termination
+ self.assertIsNotNone(process)
self.assertIsNone(terminate_subprocess(task=process))
+ # Clean up any created files
+ import os
+ test_file = "test.h5"
+ if os.path.exists(test_file):
+ os.remove(test_file)Alternatively, if you want to test the data_dict functionality specifically, consider removing the command parameter and letting the function execute the sleep function directly.

In tests/test_cache_fileexecutor_serial.py around lines 218 to 224, the
test_execute_in_subprocess function redundantly passes both a shell command and
a data_dict, which is confusing. To fix this, remove the command parameter if
you want to test the data_dict execution path specifically. Also, add
verification that the subprocess has started before terminating it to avoid race
conditions; for example, wait briefly or check process status before calling
terminate_subprocess. This will make the test more robust and clear.
