Documentation xunit2rst
=======================

This script can convert a JUnit/xUnit (.xml) file to a reStructuredText (.rst) file with traceable items.

.. contents:: `Contents`
    :depth: 2
    :local:

----
Goal
----

This script allows you to connect your test reports to your test cases via the `mlx.traceability`_ Sphinx extension.

------------
Installation
------------

.. code-block:: console

    pip3 install mlx.xunit2rst

-----
Usage
-----

.. code-block:: console

    mlx.xunit2rst -i itest_report.xml -o my_lib_report.rst --prefix ITEST_MY_LIB-

    usage: xunit2rst [-h] -i INPUT_FILE -o RST_OUTPUT_FILE [--only EXPRESSION] [-s]
                     [-p PREFIX] [--suffix SUFFIX] [--trim-suffix]
                     [--unit-or-integration UNIT_OR_INTEGRATION] [-t TYPE] [-f] [-l LOG]
                     [--links] [-v]

    options:
      -h, --help            show this help message and exit
      -i INPUT_FILE, --input INPUT_FILE
                            The input XML file
      -o RST_OUTPUT_FILE, --output RST_OUTPUT_FILE
                            The output RST file
      --only EXPRESSION     Expression of tags for Sphinx' `only` directive that surrounds all
                            RST content. By default, no `only` directive is generated.
      -s, --itemize-suites  Flag to itemize testsuite elements instead of testcase elements.
      -p PREFIX, --prefix PREFIX
                            Optional prefix to add to item IDs
      --suffix SUFFIX       Optional suffix to add to the prefix for the item IDs, except for
                            the test cases
      --trim-suffix         If the suffix of the --prefix argument ends with '_-' it gets
                            trimmed to '-'
      --unit-or-integration UNIT_OR_INTEGRATION
                            Deprecated alternative to --type; to be removed in version 2.0.0.
      -t TYPE, --type TYPE  Optional: give value starting with 'u', 'i' or 'q' to explicitly
                            define the type of test: unit/integration/qualification test
      -f, --failure-message
                            Include the error message in case of test failure in the item's
                            body.
      -l LOG, --log LOG     Optional: path to the HTML log file, relative to where Sphinx will
                            put the --output, to create a link to.
      --links               Optional: inserts a link to the RobotFramework HTML log file for
                            each test case as ext_robotframeworklog link id.
      -v, --version         show program's version number and exit

If you use the ``--only`` input argument, you should also add |sphinx_selective_exclude.eager_only|_ to the
``extensions`` list to prevent `mlx.traceability`_ from parsing the content and ignoring the effect of the
``only`` directive.

.. _`mlx.traceability`: https://pypi.org/project/mlx.traceability/
.. |sphinx_selective_exclude.eager_only| replace:: ``'sphinx_selective_exclude.eager_only'``
.. _sphinx_selective_exclude.eager_only: https://pypi.org/project/sphinx-selective-exclude/

--------
Behavior
--------

Itemization
===========

By default, all *testcase* elements from the input file are used to created treaceability items. This may not always be
desired. The ``-s, --itemize-suites`` flag lets the script itemize *testsuite* elements instead. In this case, the
*testcase* elements will still be parsed to determine whether the testsuite passed or failed or skipped.

Test Result of Itemized Suites
------------------------------

Pass (passes)
  No test cases have failed. Some might be skipped.

Fail (fails)
  At least one test case has failed.

Skip (skipped)
  All test cases have been skipped.

Item IDs
========

The *name* attribute of the element to be itemized is used to build the item ID. Lower case letters get converted to
upper case, whitespaces get converted to underscores, and *&* characters get converted to *AND*. A valid prefix must
end with a hyphen to be recognized by the script. If there is an additional string prepended to this name by means of a
dot, this string won't be taken into account. Example below:

``MY_LIB.ITEST_MY_LIB-my function & keyword`` XML element name results in item ID
``ITEST_MY_LIB-MY_FUNCTION_AND_KEYWORD``

Prefix
======

Traceability item IDs have a prefix that is unique for the group they belong to, e.g. *ITEST_MY_LIB-*. The ``--prefix``
input argument lets you configure this prefix. It will be prepended to the item names found in the input file to build
the item ID. By default, the script adds *ITEST-* or *UTEST-* for integration or unit test reports, unless the prefixes
already exist in the input file.

By default, the test case report items get the same prefix as the test case items. You can extend the prefix of the
test case report items by means of the ``--suffix`` input argument, which simply appends its value to the prefix
(in front of the ``-`` character).

Distinction Between Unit and Integration Test Reports
=====================================================

Test reports that have a *testsuites* element as root in XML are treated as unit test reports. Otherwise the script
treats the input file as an integration test report. This discerning behavior gets overridden when prefixes are found in
the input file or the ``--prefix`` input argument is used. The script looks for a *U* or *I* as the first letter of the
prefix. Lastly, you can explicitly define the type by using the ``--type`` input argument.
Its value should start with *u* or *i* and gets parsed case-insensitively.

Include Message of Failure(s)
=============================

When the ``-f, --failure-message`` flag is set, the tool includes the messages of all failures and reasons for skipping
of the item's test cases in its body.

.. _content:

Add Content to Test Reports
===========================

Extra reStructuredText content for the generated test reports can be defined in a YAML_ file that contains a
mapping, aka `dictionary`_, of case insensitive test case names or (parent) test suite names as
keys and reStructuredText strings as values. `Multiline strings`_ are supported. This feature is used in the `example
documentation`_.

When using the ``-s, --itemize-suites`` flag, the YAML keys should match the converted test suite names instead of
individual test case names. The suite name conversion follows the same rules as test case names: the name is converted
to uppercase, special characters are replaced with underscores, and any prefix before a dot is removed.

The path to the YAML file, an absolute path or relative to the input XML file, must be added as a metadata element to
the XML content, with the string ``xunit2rst content file`` as name and the path as value.

Examples of valid metadata in XML:

.. code:: xml

    <properties>
      <property name="xunit2rst content file" value="../extra_content.yml"/>
    </properties>

    <traits>
      <trait name="xUnit2rst Content File" value="/home/user/git/test_project/extra_content.yml"/>
    </traits>

When using Robot Framework v5 or greater, this path can be provided as `Free test suite metadata`_.

Using Mako Templates for Dynamic Content
-----------------------------------------

For even greater flexibility, you can use Mako_ templates to generate YAML content dynamically. If the content filename
ends with ``.yml.mako`` or ``.yaml.mako``, it will be treated as a Mako template and rendered before parsing as YAML.
This allows you to generate content based on test parameters that are stored in another file, for example.

Inside your Mako template, you have access to the following variables, in addition to your environment variables:

input_file:
    The path to the input XML file.


Suite Header Content Example
-----------------------------

(Parent) suite content appears as header documentation above the table of contents:

XML file with test suites:

.. code:: xml

    <testsuites>
        <testsuite name="MY_LIB.UTEST_MY_LIB-CORE_FUNCTIONS" tests="3">
            <testcase name="test_function_a"/>
            <testcase name="test_function_b"/>
            <testcase name="test_function_c"/>
            <properties>
                <property name="xunit2rst content file" value="header_content.yml"/>
            </properties>
        </testsuite>
    </testsuites>

Content file (``header_content.yml``):

.. code:: yaml

    UTEST_MY_LIB-CORE_FUNCTIONS: |
      .. note::
          **Test Suite Overview**

          This suite tests the core functionality of MY_LIB.
          All functions are critical for system operation.

Generated RST output structure:

.. code:: rst

    Unit Test Report for my_project
    ===============================

    .. note::
        **Test Suite Overview**

        This suite tests the core functionality of MY_LIB.
        All functions are critical for system operation.

    .. contents:: `Contents`
        :depth: 2
        :local:

    Test Reports
    ============

    .. item:: REPORT_UTEST_MY_LIB-TEST_FUNCTION_A ...
        (individual test case items follow)

This approach allows you to provide overview documentation for test suites without creating separate traceability items.

Links to Log File
=================

Use input parameter ``-l, --log PATH_TO_FILE`` to add a link to the HTML log file. This path should be relative to the
location where Sphinx outputs the HTML version of the RST file generated by this tool. Be sure to put this log file
in Sphinx' source directory and add it to html_extra_path_ in your *conf.py*. This way, the log file will end up in
the root of Sphinx' output location.

The ``--links`` flag adds a link to each generated traceability item in the form of an `external relationship`_.
This requires you to configure the relationship `ext_robotframeworklog` in your *conf.py* like this:

.. code-block:: python

    traceability_relationships = {
        'ext_robotframeworklog': '',
    }
    traceability_relationship_to_string = {
        'ext_robotframeworklog': 'Details in log file',
    }
    traceability_external_relationship_to_url = {
        'ext_robotframeworklog': 'field1#field2'
    }

Color Test Results
==================

You can highlight each test result (pass, fail and skip) in a different color so that they stand out
more from the rest of the report.
The element with the test result text contains two classes: `xunit2rst` and the test result itself.
For HTML documentation, you can use the CSS stylesheet_, provided with the Python package,
by passing it to Sphinx with `add_css_file`_, or by adding its contents manually to your own stylesheet.

This feature is demonstrated in the `test reports`_ of the example documentation.
