## 3.2.9 - 2018-12-01 {#version-3-2-9}

### Improvements

  * Added support for data generation by method. `data_#{test_name}`
    is called to generate data for `test_name` test.

  * Added support for data matrix generation.

    Example:

    ```ruby
    data(:a, [0, 1, 2])
    data(:b, [:x, :y])
    def test_data(data)
    end
    ```

    This example generates the following data matrix:

      * label: `"a: 0, b: :x"`, data: `{a: 0, b: :x}`
      * label: `"a: 0, b: :y"`, data: `{a: 0, b: :y}`
      * label: `"a: 1, b: :x"`, data: `{a: 1, b: :x}`
      * label: `"a: 1, b: :y"`, data: `{a: 1, b: :y}`
      * label: `"a: 2, b: :x"`, data: `{a: 2, b: :x}`
      * label: `"a: 2, b: :y"`, data: `{a: 2, b: :y}`

  * Added `Test::Unit::TestCase#data` that returns the current data.

  * Added support for using test method that doesn't have no
    parameters as data driven test.

    Example:

    ```ruby
    data("label", :value)
    def test_data # Available since this release
      p data # :value
    end
    ```

  * Added support for `:keep` option to `Test::Unit::TestCase.data`.

  * Added support for `:group` option to
    `Test::Unit::TestCase.data`. It's useful to generate multiple data
    matrix groups.

    ```ruby
    # Group1
    data(:a, [0, 1, 2], group: :g1)
    data(:b, [:x, :y], group: :g1)
    # Group2
    data(:a, [:x, :y], group: :g2)
    data(:c, [-1, -2], group: :g2)
    def test_data(data)
    end
    ```

    This example generates the following data matrix:

      * label: `"group: :g1, a: 0, b: :x"`, data: `{a: 0, b: :x}`
      * label: `"group: :g1, a: 0, b: :y"`, data: `{a: 0, b: :y}`
      * label: `"group: :g1, a: 1, b: :x"`, data: `{a: 1, b: :x}`
      * label: `"group: :g1, a: 1, b: :y"`, data: `{a: 1, b: :y}`
      * label: `"group: :g1, a: 2, b: :x"`, data: `{a: 2, b: :x}`
      * label: `"group: :g1, a: 2, b: :y"`, data: `{a: 2, b: :y}`
      * label: `"group: :g2, a: :x, b: -1"`, data: `{a: :x, b: -1}`
      * label: `"group: :g2, a: :x, b: -2"`, data: `{a: :x, b: -2}`
      * label: `"group: :g2, a: :y, b: -1"`, data: `{a: :y, b: -1}`
      * label: `"group: :g2, a: :y, b: -2"`, data: `{a: :y, b: -2}`

## 3.1.8 - 2016-03-19 {#version-3-1-8}

  * Added `--stop-on-failure` command line option. With this option,
    running test suite is stopped immediately when one test is failed
    or an error is raised in one test.

## 3.1.7 - 2016-01-17 {#version-3-1-7}

### Fixes

 * Added a missing require.

## 3.1.6 - 2016-01-17 {#version-3-1-6}

It's a Ruby on Rails integration improvement release.

### Improvements

  * Filtered backtrace of power\_assert.
    [GitHub#114]
  * Improved performance to retrieve test defined location.
  * Improved performance to run fixtures in a test.
  * Supported running a test by `yield` in `setup`:

    Before:

        def setup
          @file = File.open("x")
        end

        def teardown
          @file.close
        end

    After:

        def setup
          File.open("x") do |file|
            @file = file
            yield
          end
        end

  * Added `--default-test-path` option that specifies the default path
    that has tests.
  * Made auto runner registration more lazily. Auto runner isn't
    registered automatically until user defines a test. In the
    previous releases, auto runner is registered automatically when
    user defines a test case.
  * Supported specifying a test by location in command line. For
    example, the following command line runs a test that is defined in
    /tmp/test_a.rb at line 10:

        % ruby -r test-unit -e run_test /tmp/test_a.rb:10

### Fixes

  * Fixed a bug that test isn't ran. The test has the same name as
    data driven test that is defined in parent test case.

    * Before:

        matched.
    * After:
      * If base name of test defined path equals to the specified
        path, the test is matched.
      * If relative path of test defined path equals to the specified
        path, the test is matched.
      * If the specified path is absolute path and test defined path
        equals to the specified path, the test is matched.
  * `--pattern`: If the option is specified, the default patterns
    aren't used. In the earlier versions, both the default patterns
    and the specified patterns are used.

It's Power Assert supported release!

### Improvements

  * Improved Rubinius support. [Ryo Onodera]
  * Updated RR repository link. [GitHub#56][Patch by Kenichi Kamiya]

    using these assertions. They are just for migrating from minitest.
    [GitHub#57][Patch by Karol Bucek]
    * {Test::Unit::Assertions#refute}
    * {Test::Unit::Assertions#refute_predicate}
    * {Test::Unit::Assertions#refute_empty}

    [GitHub#65][Patch by Byron Appelt]
  * Supported Power Assert. You can use Power Assert with
    {Test::Unit::Assertions#assert} with block. See method document
    for details. We recommend using Power Assert for predicate method
    checks. For example, we recommend Power Assert rather than
    {Test::Unit::Assertions#assert_true},
    {Test::Unit::Assertions#assert_predicate} and so on. We don't
    recommend using Power Assert for equality check assertion.
    {Test::Unit::Assertions#assert_equal} should be used for the case.

### Fixes

  * Fixed a bug that test case defined by block has wrong location.
