> pry --help
Usage: pry [options] [testfilter]

Options:
  --version             show program's version number and exit
  -h, --help            show this help message and exit
  -l, --list            List all tests.
  -r, --recurse         Recurse through child directories.
  -s, --stats           Print coverage summary.
  -n BENCHMARK, --benchmark=BENCHMARK
                        Run each test N times.
  -q, --quiet           Quiet.
  -v, --verbose         Increase verbosity. Can be passed multiple times.
  --debug-dump          For debugging only. Like -l, but dump the full tree
                        structure.

  Profiling:
    Generating run profiles for unit tests.

    -p, --profile       Do a profiling run. Usually used in conjunction with
                        -n to specify multiple runs.
    --profile-sort=PROFILE_SORT
                        Profile result sorting key. See Python documentation
                        for pstats module.

Test Selection

The optional test filter that can be specified to pry operates as follows:

• First, all tests in the current directory are loaded (recursively if the -r flag is specified).

• Then, the filter is applied to select a subset of tests based on a partial match strategy.

The following examples illustrate the process (commands are run in the examples subdirectory):

> pry -l
./test_autotree
     MyContainer
         test_one
         test_two
./test_basic
     MySuite
         test_one
         test_three
         test_two
./test_profile
     ProfTest
         test_one
./test_trees
     MyContainer
         test_one
         test_two
Total: 8

> pry -l test_basic
./test_basic
     MySuite
         test_one
         test_three
         test_two
Total: 3

> pry -l test_one
./test_autotree
     MyContainer
         test_one
./test_basic
     MySuite
         test_one
./test_profile
     ProfTest
         test_one
./test_trees
     MyContainer
         test_one
Total: 4

> pry -l ProfTest.test_one
./test_profile
     ProfTest
         test_one
