Configuration

This plugin provides a clean minimal set of command line options that are added to pytest. You can also specify most options in pytest.ini file. The complete list of command line options is:

Command line options

--memray

Activate memray tracking.

--most-allocations=MOST_ALLOCATIONS

Show the N tests that allocate most memory (N=0 for all).

--hide-memray-summary

Hide the memray summary at the end of the execution.

--memray-bin-path

Path where to write the memray binary dumps (by default a temporary folder).

--memray-bin-prefix

Prefix to use for the binary dump (by default a random UUID4 hex)

--stacks=STACKS

Show the N most recent stack entries when showing tracebacks of memory allocations

--native

Include native frames when showing tracebacks of memory allocations (will be slower)

--trace-python-allocators

Record allocations made by the Pymalloc allocator (will be slower)

--fail-on-increase

Fail a test with the limit_memory marker if it uses more memory than its last successful run
