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}`

* doc: Fixed markup. [GitHub#127](https://github.com/test-unit/test-unit/issues/127)[Patch by Tomohiro Hashidate]

* Fixed a bug that `--location=LINE` may not detect a test when
fixtures are defined before any tests:

    1 class MyTestCase < Test::Unit::TestCase
    2   setup do
    3   end
    4
    5   test "xxx" do
    6   end
    7 end

`--location=5` couldn't find the `xxx` test.

3.1.8 - 2016-03-19 `#version-3-1-8`

or an error is raised in one test.

3.1.7 - 2016-01-17 `#version-3-1-7`

Added a missing require.

3.1.6 - 2016-01-17 `#version-3-1-6`

Improvements

* Filtered backtrace of power\_assert.
[GitHub#114](https://github.com/test-unit/test-unit/issues/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.

It's command line option improvements fix release.

Improvements

[Suggested by kimura wataru]
* Before:
  * If test defined path ends with the specified path, the test is
    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.
