Managing pytest's output
=========================

.. _how-to-modifying-python-tb-printing:

Modifying Python traceback printing
--------------------------------------------------

Examples for modifying traceback printing:

.. code-block:: bash

    pytest --showlocals     # show local variables in tracebacks
    pytest -l               # show local variables (shortcut)
    pytest --no-showlocals  # hide local variables (if addopts enables them)

    pytest --capture=fd  # default, capture at the file descriptor level
    pytest --capture=sys # capture at the sys level
    pytest --capture=no  # don't capture
    pytest -s            # don't capture (shortcut)
    pytest --capture=tee-sys # capture to logs but also output to sys level streams

    pytest --tb=auto    # (default) 'long' tracebacks for the first and last
                         # entry, but 'short' style for the other entries
    pytest --tb=long    # exhaustive, informative traceback formatting
    pytest --tb=short   # shorter traceback format
    pytest --tb=line    # only one line per failure
    pytest --tb=native  # Python standard library formatting
    pytest --tb=no      # no traceback at all

The :option:`--full-trace` causes very long traces to be printed on error (longer
than :option:`--tb=long`). It also ensures that a stack trace is printed on
**KeyboardInterrupt** (Ctrl+C).
This is very useful if the tests are taking too long and you interrupt them
with Ctrl+C to find out where the tests are *hanging*. By default no output
will be shown (because KeyboardInterrupt is caught by pytest). By using this
option you make sure a trace is shown.


Verbosity
--------------------------------------------------

Examples for modifying printing verbosity:

.. code-block:: bash

    pytest --quiet          # quiet - less verbose - mode
    pytest -q               # quiet - less verbose - mode (shortcut)
    pytest -v               # increase verbosity, display individual test names
    pytest -vv              # more verbose, display more details from the test output
    pytest -vvv             # not a standard , but may be used for even more detail in certain setups

The :option:`-v` flag controls the verbosity of pytest output in various aspects: test session progress, assertion
details when tests fail, fixtures details with :option:`--fixtures`, etc.

.. regendoc:wipe

Consider this simple file:

.. code-block:: python

    # content of test_verbosity_example.py
    def test_ok():
        pass


    def test_words_fail():
        fruits1 = ["banana", "apple", "grapes", "melon", "kiwi"]
        fruits2 = ["banana", "apple", "orange", "melon", "kiwi"]
        assert fruits1 == fruits2


    def test_numbers_fail():
        number_to_text1 = {str(x): x for x in range(5)}
        number_to_text2 = {str(x * 10): x * 10 for x in range(5)}
        assert number_to_text1 == number_to_text2


    def test_long_text_fail():
        long_text = "Lorem ipsum dolor sit amet " * 10
        assert "hello world" in long_text

Executing pytest normally gives us this output (we are skipping the header to focus on the rest):

Notice that:

  because it is longer than an internal threshold (240 characters currently).

Now we can increase pytest's verbosity:

Now if we increase verbosity even more:

    ======================= 3 failed, 1 passed in 0.12s ========================

Notice now that:

* Each test inside the file gets its own line in the output.
* ``test_words_fail`` gives the same output as before in this case.
* ``test_numbers_fail`` now shows a full text diff of the two dictionaries.
* ``test_long_text_fail`` also doesn't truncate on the right hand side as before, but now pytest won't truncate any
  text at all, regardless of its size.

Those were examples of how verbosity affects normal test session output, but verbosity also is used in other
situations, for example you are shown even fixtures that start with ``_`` if you use ``pytest --fixtures -v``.

Using higher verbosity levels (``-vvv``, ``-vvvv``, ...) is supported, but has no effect in pytest itself at the moment,
however some plugins might make use of higher verbosity.

.. _`pytest.fine_grained_verbosity`:

Fine-grained verbosity
~~~~~~~~~~~~~~~~~~~~~~

In addition to specifying the application wide verbosity level, it is possible to control specific aspects independently.
This is done by setting a verbosity level in the configuration file for the specific aspect of the output.

:confval:`verbosity_assertions`: Controls how verbose the assertion output should be when pytest is executed. Running
``pytest --no-header`` with a value of ``2`` would have the same output as the previous example, but each test inside
the file is shown by a single character in the output.

:confval:`assertion_text_diff_style`: Controls how pytest renders ``str == str`` failures.

  * ``ndiff`` (the default) outputs the differences using inline diff markers.
  * ``block`` prints string comparisons as separate ``Left:`` and ``Right:`` blocks, which can be easier to read when whitespace or indentation differences dominate.

  Note that it is possible to set this option (as any other configuration option) directly in the command line using ``-o assertion_text_diff_style=block``.

:confval:`verbosity_test_cases`: Controls how verbose the test execution output should be when pytest is executed.
Running ``pytest --no-header`` with a value of ``2`` would have the same output as the first verbosity example, but each
test inside the file gets its own line in the output.

.. _`pytest.detailed_failed_tests_usage`:

Producing a detailed summary report
--------------------------------------------------

The :option:`-r` flag can be used to display a "short test summary info" at the end of the test session,
making it easy in large test suites to get a clear picture of all failures, skips, xfails, etc.

It defaults to ``fE`` to list failures and errors.

    == 1 failed, 1 passed, 1 skipped, 1 xfailed, 1 xpassed, 1 error in 0.12s ===

The :option:`-r` options accepts a number of characters after it, with ``a`` used
above meaning "all except passes".

Here is the full list of available characters that can be used:

 - ``f`` - failed
 - ``E`` - error
 - ``s`` - skipped
 - ``x`` - xfailed
 - ``X`` - xpassed
 - ``p`` - passed
 - ``P`` - passed with output

Special characters for (de)selection of groups:

 - ``a`` - all except ``pP``
 - ``A`` - all
 - ``N`` - none, this can be used to display nothing (since ``fE`` is the default)

More than one character can be used, so for example to only see failed and skipped tests, you can execute:

.. note::

    By default, parametrized variants of skipped tests are grouped together if
    they share the same skip reason. You can use :option:`--no-fold-skipped` to print each skipped test separately.


.. _truncation-params:

Modifying truncation limits
--------------------------------------------------

.. versionadded: 8.4

Default truncation limits are 8 lines or 640 characters, whichever comes first.
To set custom truncation limits you can use the following configuration file options:

.. tab:: toml

    .. code-block:: toml

        [pytest]
        truncation_limit_lines = 10
        truncation_limit_chars = 90

.. tab:: ini

    .. code-block:: ini

        [pytest]
        truncation_limit_lines = 10
        truncation_limit_chars = 90

That will cause pytest to truncate the assertions to 10 lines or 90 characters, whichever comes first.

Setting both :confval:`truncation_limit_lines` and :confval:`truncation_limit_chars` to ``0`` will disable the truncation.
However, setting only one of those values will disable one truncation mode, but will leave the other one intact.


Creating JUnitXML format files
----------------------------------------------------

To create result files which can be read by Jenkins_ or other Continuous
integration servers, use this invocation:

.. code-block:: bash

    pytest --junit-xml=path

to create an XML file at ``path``.



To set the name of the root test suite xml item, you can configure the ``junit_suite_name`` option in your config file:

.. tab:: toml

    .. code-block:: toml

        [pytest]
        junit_suite_name = "my_suite"

.. tab:: ini

    .. code-block:: ini

        [pytest]
        junit_suite_name = my_suite

.. versionadded:: 4.0

JUnit XML specification seems to indicate that ``"time"`` attribute
should report total test execution times, including setup and teardown
(`1 <http://windyroad.com.au/dl/Open%20Source/JUnit.xsd>`_, `2
<https://www.ibm.com/support/knowledgecenter/en/SSQ2R2_14.1.0/com.ibm.rsar.analysis.codereview.cobol.doc/topics/cac_useresults_junit.html>`_).
It is the default pytest behavior. To report just call durations
instead, configure the ``junit_duration_report`` option like this:

.. tab:: toml

    .. code-block:: toml

        [pytest]
        junit_duration_report = "call"

.. tab:: ini

    .. code-block:: ini

        [pytest]
        junit_duration_report = call

.. _record_property example:

record_property
~~~~~~~~~~~~~~~~~

If you want to log additional information for a test, you can use the
``record_property`` fixture:

.. code-block:: python

    def test_function(record_property):
        record_property("example_key", 1)
        assert True

This will add an extra property ``example_key="1"`` to the generated
``testcase`` tag:

.. code-block:: xml

    <testcase classname="test_function" file="test_function.py" line="0" name="test_function" time="0.0009">
      <properties>
        <property name="example_key" value="1" />
      </properties>
    </testcase>

Alternatively, you can integrate this functionality with custom markers:

.. code-block:: python

    # content of conftest.py


    def pytest_collection_modifyitems(session, config, items):
        for item in items:
            for marker in item.iter_markers(name="test_id"):
                test_id = marker.args[0]
                item.user_properties.append(("test_id", test_id))

And in your tests:

.. code-block:: python

    # content of test_function.py
    import pytest


    @pytest.mark.test_id(1501)
    def test_function():
        assert True

Will result in:

.. code-block:: xml

    <testcase classname="test_function" file="test_function.py" line="0" name="test_function" time="0.0009">
      <properties>
        <property name="test_id" value="1501" />
      </properties>
    </testcase>

.. warning::

    Please note that using this feature will break schema verifications for the latest JUnitXML schema.
    This might be a problem when used with some CI servers.


record_xml_attribute
~~~~~~~~~~~~~~~~~~~~~~~

To add an additional xml attribute to a testcase element, you can use
``record_xml_attribute`` fixture. This can also be used to override existing values:

.. code-block:: python

    def test_function(record_xml_attribute):
        record_xml_attribute("assertions", "REQ-1234")
        record_xml_attribute("classname", "custom_classname")
        print("hello world")
        assert True

Unlike ``record_property``, this will not add a new child element.
Instead, this will add an attribute ``assertions="REQ-1234"`` inside the generated
``testcase`` tag and override the default ``classname`` with ``"classname=custom_classname"``:

.. code-block:: xml

    <testcase classname="custom_classname" file="test_function.py" line="0" name="test_function" time="0.003" assertions="REQ-1234">
        <system-out>
            hello world
        </system-out>
    </testcase>

.. warning::

    ``record_xml_attribute`` is an experimental feature, and its interface might be replaced
    by something more powerful and general in future versions. The
    functionality per-se will be kept, however.

    Using this over ``record_xml_property`` can help when using ci tools to parse the xml report.
    However, some parsers are quite strict about the elements and attributes that are allowed.
    Many tools use an xsd schema (like the example below) to validate incoming xml.
    Make sure you are using attribute names that are allowed by your parser.

    Below is the Scheme used by Jenkins to validate the XML report:

    .. code-block:: xml

        <xs:element name="testcase">
            <xs:complexType>
                <xs:sequence>
                    <xs:element ref="skipped" minOccurs="0" maxOccurs="1"/>
                    <xs:element ref="error" minOccurs="0" maxOccurs="unbounded"/>
                    <xs:element ref="failure" minOccurs="0" maxOccurs="unbounded"/>
                    <xs:element ref="system-out" minOccurs="0" maxOccurs="unbounded"/>
                    <xs:element ref="system-err" minOccurs="0" maxOccurs="unbounded"/>
                </xs:sequence>
                <xs:attribute name="name" type="xs:string" use="required"/>
                <xs:attribute name="assertions" type="xs:string" use="optional"/>
                <xs:attribute name="time" type="xs:string" use="optional"/>
                <xs:attribute name="classname" type="xs:string" use="optional"/>
                <xs:attribute name="status" type="xs:string" use="optional"/>
            </xs:complexType>
        </xs:element>

.. warning::

    Please note that using this feature will break schema verifications for the latest JUnitXML schema.
    This might be a problem when used with some CI servers.

.. _record_testsuite_property example:

record_testsuite_property
^^^^^^^^^^^^^^^^^^^^^^^^^

.. versionadded:: 4.5

If you want to add a properties node at the test-suite level, which may contain properties
that are relevant to all tests, you can use the ``record_testsuite_property`` session-scoped fixture:

The ``record_testsuite_property`` session-scoped fixture can be used to add properties relevant
to all tests.

.. code-block:: python

    import pytest


    @pytest.fixture(scope="session", autouse=True)
    def log_global_env_facts(record_testsuite_property):
        record_testsuite_property("ARCH", "PPC")
        record_testsuite_property("STORAGE_TYPE", "CEPH")


    class TestMe:
        def test_foo(self):
            assert True

The fixture is a callable which receives ``name`` and ``value`` of a ``<property>`` tag
added at the test-suite level of the generated xml:

.. code-block:: xml

    <testsuite errors="0" failures="0" name="pytest" skipped="0" tests="1" time="0.006">
      <properties>
        <property name="ARCH" value="PPC"/>
        <property name="STORAGE_TYPE" value="CEPH"/>
      </properties>
      <testcase classname="test_me.TestMe" file="test_me.py" line="16" name="test_foo" time="0.000243663787842"/>
    </testsuite>

``name`` must be a string, ``value`` will be converted to a string and properly xml-escaped.

The generated XML is compatible with the latest ``xunit`` standard, contrary to `record_property`_
and `record_xml_attribute`_.


Sending test report to an online pastebin service
--------------------------------------------------

**Creating a URL for each test failure**:

.. code-block:: bash

    pytest --pastebin=failed

This will submit test run information to a remote Paste service and
provide a URL for each failure.  You may select tests as usual or add
for example :option:`-x` if you only want to send one particular failure.

**Creating a URL for a whole test session log**:

.. code-block:: bash

    pytest --pastebin=all

Currently only pasting to the https://bpaste.net/ service is implemented.

.. versionchanged:: 5.2

If creating the URL fails for any reason, a warning is generated instead of failing the
entire test suite.
