3.2.1 (2017-01-10)

  • Updated changelog entries for 3.2.0. I made the release for pytest-cov on the same day and thought I updated the changelogs for both plugins. Alas, I only updated pytest-cov.
  • Added missing version constraint change. Now pytest >= 3.8 is required (due to pytest 4.1 support).
  • Fixed couple CI/test issues.
  • Fixed broken pytest_benchmark.__version__.

3.1.1 (2017-07-26)

  • Fixed loading data from old json files (missing ops field, see #81).
  • Fixed regression on broken SCM (see #82).

3.1.0 (2017-07-21)

  • Added "operations per second" (ops field in Stats) metric -- shows the call rate of code being tested. Contributed by Alexey Popravka in #78.
  • Added a time field in commit_info. Contributed by "varac" in #71.
  • Added a author_time field in commit_info. Contributed by "varac" in #75.
  • Fixed the leaking of credentials by masking the URL printed when storing data to elasticsearch.
  • Added a --benchmark-netrc option to use credentials from a netrc file when storing data to elasticsearch. Both contributed by Andre Bianchi in #73.
  • Fixed docs on hooks. Contributed by Andre Bianchi in #74.
  • Remove git and hg as system dependencies when guessing the project name.

3.1.0a2 (2017-03-27)

  • machine_info now contains more detailed information about the CPU, in particular the exact model. Contributed by Antonio Cuni in #61.
  • Added benchmark.extra_info, which you can use to save arbitrary stuff in the JSON. Contributed by Antonio Cuni in the same PR as above.
  • Fix support for latest PyGal version (histograms). Contributed by Swen Kooij in #68.

  • Added an alternate pytest-benchmark CLI bin (in addition to py.test-benchmark) to match the madness in pytest.
  • Fix some issues with --help in CLI.
  • Improved git remote parsing (for commit_info in JSON outputs).
  • Fixed default value for --benchmark-columns.
  • Fixed comparison mode (loading was done too late).
  • Remove the project name from the autosave name. This will get the old brief naming from 3.0 back.

3.1.0a1 (2016-10-29)

  • Added --benchmark-colums command line option. It selects what columns are displayed in the result table. Contributed by Antonio Cuni in #34.
  • Added support for grouping by specific test parametrization (--benchmark-group-by=param:NAME where NAME is your param name). Contributed by Antonio Cuni in #37.
  • Added support for name or fullname in --benchmark-sort. Contributed by Antonio Cuni in #37.
  • Changed signature for pytest_benchmark_generate_json hook to take 2 new arguments: machine_info and commit_info.
  • Changed --benchmark-histogram to plot groups instead of name-matching runs.
  • Changed --benchmark-histogram to plot exactly what you compared against. Now it's 1:1 with the compare feature.
  • Changed --benchmark-compare to allow globs. You can compare against all the previous runs now.
  • Changed --benchmark-group-by to allow multiple values separated by comma. Example: --benchmark-group-by=param:foo,param:bar
  • Added a command line tool to compare previous data: py.test-benchmark. It has two commands:
    • list - Lists all the available files.
    • compare - Displays result tables. Takes optional arguments:
      • --sort=COL
      • --group-by=LABEL
      • --columns=LABELS
      • --histogram=[FILENAME-PREFIX]
  • Added --benchmark-cprofile that profiles last run of benchmarked function. Contributed by Petr Šebek.
  • Changed --benchmark-storage so it now allows elasticsearch storage. It allows to store data to elasticsearch instead to json files. Contributed by Petr Šebek in #58.

3.0.0 (2015-11-08)

  • Improved --help text for --benchmark-histogram, --benchmark-save and --benchmark-autosave.
  • Benchmarks that raised exceptions during test now have special highlighting in result table (red background).
  • Benchmarks that raised exceptions are not included in the saved data anymore (you can still get the old behavior back by implementing pytest_benchmark_generate_json in your conftest.py).
  • The plugin will use pytest's warning system for warnings. There are 2 categories: WBENCHMARK-C (compare mode issues) and WBENCHMARK-U (usage issues).
  • The red warnings are only shown if --benchmark-verbose is used. They still will be always be shown in the pytest-warnings section.
  • Using the benchmark fixture more than one time is disallowed (will raise exception).
  • Not using the benchmark fixture (but requiring it) will issue a warning (WBENCHMARK-U1).

3.0.0rc1 (2015-10-25)

  • Changed --benchmark-warmup to take optional value and automatically activate on PyPy (default value is auto). MAY BE BACKWARDS INCOMPATIBLE
  • Removed the version check in compare mode (previously there was a warning if current version is lower than what's in the file).

3.0.0b3 (2015-10-22)

  • Changed how comparison is displayed in the result table. Now previous runs are shown as normal runs and names get a special suffix indicating the origin. Eg: "test_foobar (NOW)" or "test_foobar (0123)".
  • Fixed sorting in the result table. Now rows are sorted by the sort column, and then by name.
  • Show the plugin version in the header section.
  • Moved the display of default options in the header section.

3.0.0b2 (2015-10-17)

  • Add a --benchmark-disable option. It's automatically activated when xdist is on
  • When xdist is on or statistics can't be imported then --benchmark-disable is automatically activated (instead of --benchmark-skip). BACKWARDS INCOMPATIBLE
  • Replace the deprecated __multicall__ with the new hookwrapper system.
  • Improved description for --benchmark-max-time.

3.0.0b1 (2015-10-13)

  • Tests are sorted alphabetically in the results table.
  • Failing to import statistics doesn't create hard failures anymore. Benchmarks are automatically skipped if import failure occurs. This would happen on Python 3.2 (or earlier Python 3).

3.0.0a4 (2015-10-08)

  • Changed how failures to get commit info are handled: now they are soft failures. Previously it made the whole test suite fail, just because you didn't have git/hg installed.

3.0.0a3 (2015-10-02)

  • Added progress indication when computing stats.

3.0.0a2 (2015-09-30)

  • Fixed accidental output capturing caused by capturemanager misuse.

3.0.0a1 (2015-09-13)

  • Added JSON report saving (the --benchmark-json command line arguments). Based on initial work from Dave Collins in #8.
  • Added benchmark data storage(the --benchmark-save and --benchmark-autosave command line arguments).
  • Added comparison to previous runs (the --benchmark-compare command line argument).
  • Added performance regression checks (the --benchmark-compare-fail command line argument).
  • Added possibility to group by various parts of test name (the --benchmark-compare-group-by command line argument).
  • Added historical plotting (the --benchmark-histogram command line argument).
  • Added option to fine tune the calibration (the --benchmark-calibration-precision command line argument and calibration_precision marker option).
  • Changed benchmark_weave to no longer be a context manager. Cleanup is performed automatically. BACKWARDS INCOMPATIBLE
  • Added benchmark.weave method (alternative to benchmark_weave fixture).
  • Added new hooks to allow customization:
    • pytest_benchmark_generate_machine_info(config)
    • pytest_benchmark_update_machine_info(config, info)
    • pytest_benchmark_generate_commit_info(config)
    • pytest_benchmark_update_commit_info(config, info)
    • pytest_benchmark_group_stats(config, benchmarks, group_by)
    • pytest_benchmark_generate_json(config, benchmarks, include_data)
    • pytest_benchmark_update_json(config, benchmarks, output_json)
    • pytest_benchmark_compare_machine_info(config, benchmarksession, machine_info, compared_benchmark)
  • Changed the timing code to:
    • Tracers are automatically disabled when running the test function (like coverage tracers).
    • Fixed an issue with calibration code getting stuck.
  • Added pedantic mode via benchmark.pedantic(). This mode disables calibration and allows a setup function.

2.5.0 (2015-06-20)

  • Improved test suite a bit (not using cram anymore).
  • Improved help text on the --benchmark-warmup option.
  • Made warmup_iterations available as a marker argument (eg: @pytest.mark.benchmark(warmup_iterations=1234)).
  • Fixed --benchmark-verbose's printouts to work properly with output capturing.
  • Changed how warmup iterations are computed (now number of total iterations is used, instead of just the rounds).
  • Fixed a bug where calibration would run forever.
  • Disabled red/green coloring (it was kinda random) when there's a single test in the results table.

2.4.1 (2015-03-16)

  • Fix regression, plugin was raising ValueError: no option named 'dist' when xdist wasn't installed.

2.4.0 (2015-03-12)

  • Add a benchmark_weave experimental fixture.
  • Fix internal failures when xdist plugin is active.
  • Automatically disable benchmarks if xdist is active.

2.3.0 (2014-12-27)

  • Moved the warmup in the calibration phase. Solves issues with benchmarking on PyPy.

    Added a --benchmark-warmup-iterations option to fine-tune that.

2.2.0 (2014-12-26)

  • Make the default rounds smaller (so that variance is more accurate).
  • Show the defaults in the --help section.

2.1.0 (2014-12-20)

  • Simplify the calibration code so that the round is smaller.
  • Add diagnostic output for calibration code (--benchmark-verbose).

2.0.0 (2014-12-19)

  • Replace the context-manager based API with a simple callback interface. BACKWARDS INCOMPATIBLE
  • Implement timer calibration for precise measurements.

1.0.0 (2014-12-15)

  • Use a precise default timer for PyPy.

? (?)

  • README and styling fixes. Contributed by Marc Abramowitz in #4.
  • Lots of wild changes.
