From b06ce542791d0d3d0ff56fdb762404e9ce5bedea Mon Sep 17 00:00:00 2001 From: Christopher Haster Date: Sun, 12 Jan 2020 22:21:09 -0600 Subject: [PATCH] Migrated the bulk of the feature-specific tests This involved some minor tweaks for the various types of tests, added predicates to the test framework (necessary for test_entries and test_alloc), and cleaned up some of the testing semantics such as reporting how many tests are filtered, showing permutation config on the result screen, and properly inheriting suite config in cases. --- .gitignore | 1 + scripts/test_.py | 126 ++++--- tests_/test_alloc.toml | 566 +++++++++++++++++++++++++++++++ tests_/test_attrs.toml | 305 +++++++++++++++++ tests_/test_dirs.toml | 122 +++++++ tests_/test_entries.toml | 611 ++++++++++++++++++++++++++++++++++ tests_/test_interspersed.toml | 262 +++++++++++++++ tests_/test_paths.toml | 294 ++++++++++++++++ tests_/test_seek.toml | 380 +++++++++++++++++++++ tests_/test_truncate.toml | 395 ++++++++++++++++++++++ 10 files changed, 3024 insertions(+), 38 deletions(-) create mode 100644 tests_/test_alloc.toml create mode 100644 tests_/test_attrs.toml create mode 100644 tests_/test_entries.toml create mode 100644 tests_/test_interspersed.toml create mode 100644 tests_/test_paths.toml create mode 100644 tests_/test_seek.toml create mode 100644 tests_/test_truncate.toml diff --git a/.gitignore b/.gitignore index 36f92cd..1e12cca 100644 --- a/.gitignore +++ b/.gitignore @@ -7,3 +7,4 @@ blocks/ lfs test.c +tests_/*.toml.* diff --git a/scripts/test_.py b/scripts/test_.py index 2f016e4..ab674c9 100755 --- a/scripts/test_.py +++ b/scripts/test_.py @@ -4,6 +4,20 @@ # .toml files stored in the tests directory. # +# TODO +# - nargs > 1?
