probatio

Test tools for floraison and flor. Somewhere between Minitest and Rspec, but not as excellent.

Goals

• versatile bundle exec proba, run this or these tests, at the line
• bundle exec proba first for first failing tests
• bundle exec proba last for last failing tests
• bundle exec proba . for the test currently edited .test-point
• bundle exec proba f for the test file currently edited .test-point
• bundle exec proba list.txt to run a list of tests
• bundle exec proba list.rb to run a list of tests (Ruby array)

Usage

Usage: bundle exec proba [OPTIONS] [DIRS] [FILES] [OTHERS] [ENVS]

  A test runner for Ruby.

  Options:
    -h, --help             Show this help message and quit
    --version              Show proba's version and exit
    -c, --color            Enable colour output anyway
    -C, --no-color         Disable colour output
    -y, --dry              Don't run the tests, just flag them as successes
    -n, --name PATTERN     include tests matching /regexp/ or string in run
    -e, --exclude PATTERN  Exclude /regexp/ or string from run
    -p, --print            Dumps the test tree
    -m, --map              Dumps the test file map
    -s, --seed             Sets random seed
    -d, --debug smr        's' for start opts, 'm' for messages, 'r' for $DEBUG
    -x, --example          Outputs an example test file
    -X, --plugin-example   Outputs an example plugin file
    --mangle               Turns the given _spec.rb files into proba _test.rb

  Dirs:
    Defaults to test/ if no files nor dir are given.
    Probatio will look at all the *_helper[s].rb, *_test[s].rb files
    under the given dirs and also at the setup.rb, *_setup.rb files

  Files:
    List of test files to scan for tests.
    A file may end with `:123` to indicate that the test at line 123 should
    be run. Multiple "colon-lnumber" suffixes may be specified, as in
    `test/fun/that_test.rb:123:456`

  Others:
    Short codes like
    * `bundle exec proba -1`
    * `bundle exec proba last` run the last failing test of the last run
    * `bundle exec proba first`
    * `bundle exec proba 1st`
    * `bundle exec proba 0` run the first failing test of the last run
  Lists:
    * `bundle exec proba list.txt` will run all the tests in list.txt
    * `bundle exec proba a_list.rb` will eval and lists the arrayed tests


  Envs:
    Short FULLCAPS environment variable setters driven by a
    `.probatio-environments.rb` file in the current work directory.

    ```
    # .probatio-environments.rb
    {
      D: { 'FLOR_DEBUG' => 'dbg,stdout' },
      DD: { 'FLOR_DEBUG' => 'dbg,sto,stdout' },
    }
    ```

  Examples:
    # Run all tests in a dir
    bundle exec proba test/

    # Run all the tests in a file
    bundle exec proba test/this_test.rb

Test files

By default probatio looks into test/ for test files ending in _test.rb or _tests.rb but first look at helpers ending in _helper.rb or _helpers.rb.

A typical test hierarchy:

test/
|-- helpers/
|   |-- some_helpers.rb
|   `-- some_other_helpers.rb
|-- this_test.rb
|-- that_test.rb
`-- more_tests.rb

group 'core' do

  setup do
    # occurs once before tests and sub-groups in group 'core'
  end
  teadowm do
    # occurs once after tests and sub-groups in group 'core'
  end

  group 'alpha' do

    before do
      # is run in the separate test context before _each_ test
    end
    after do
      # is run in the separate test context after _each_ test
    end

end

.test-point

By running bx proba ., one tells probatio to run the test pointed at in the file .test-point.

Here is an example of .test-point content:

test/wma/dwm/onboarding_benchmark_non_star_test.rb:189

For Vim users, here is a snippet that saves the current path and line number to .test-point every 700ms:

au BufEnter test/*_test.rb,test/**/*_test.rb :set updatetime=700

au BufEnter,CursorHold,BufWrite test/*_test.rb,test/**/*_test.rb :call writefile([ expand('%') . ':' . line('.') ], '.test-point', 'b')

.probatio-output.rb

By default, probatio summarizes a run in a .probatio-output.rb file.

Here is an example of such a file:

# .probatio-output.rb
{
argv: [ "test/alpha_test.rb:23" ],
failures:
  [
  { n: "test_fail", p: "test/alpha_test.rb", l: 24, t: "0s000_077" },
  { n: "test_fail", p: "test/alpha_test.rb", l: 29, t: "0s000_033" },
  ],
duration: "0s001_297",
probatio: { v: "1.0.0" },
ruby:
  {
  p: "/usr/local/bin/ruby33",
  d: "ruby 3.3.5 (2024-09-03 revision ef084cc8f4) [x86_64-openbsd]",
  l: 100,
  },
some_env:
  {
  USER: "jmettraux",
  HOME: "/home/jmettraux",
  PATH: "/home/jmettraux/.gem/ruby/3.3/bin:/home/jmettraux/.pkg_rubies/ruby33:/usr/local/jdk-21/bin:/home/jmettraux/bin:/bin:/usr/bin:/sbin:/usr/sbin:/usr/X11R6/bin:/usr/local/bin:/usr/local/sbin",
  SHELL: "/usr/local/bin/fish",
  GEM_HOME: "/home/jmettraux/.gem/ruby/3.3",
  PWD: "/home/jmettraux/w/probatio/test",
  },
}

Probatio uses it when servicing bundle exec proba 0 or bundle exe proba -1.

It can also be useful to other tools around probatio.
