Output example

Configuration

spec_header_format

spec_header_format

You can configure the format of the test headers by specifying a format string in your ini-file:

    ; since pytest 4.6.x
    [pytest]
    spec_header_format = {module_path}:

    ; legacy pytest
    [tool:pytest]
    spec_header_format = {module_path}:

or in your pyproject.toml file:

    [tool.pytest.ini_options]
    spec_header_format = "{module_path}:"

In addition to the {path} and {class_name} replacement fields, there is also {test_case} that holds a more human readable name.

spec_test_format

spec_test_format

You can configure the format of the test results by specifying a format string in your ini-file:

3 variables are available:

• result - place for indicator
• name - name of test
• docstring_summary - first line from test docstring if available

    ; since pytest 4.6.x
    [pytest]
    spec_test_format = {result} {name}

    ; legacy pytest
    [tool:pytest]
    spec_test_format = {result} {name}

or

    ; since pytest 4.6.x
    [pytest]
    spec_test_format = {result} {docstring_summary}

    ; legacy pytest
    [tool:pytest]
    spec_test_format = {result} {docstring_summary}

In second example where docstring is not available the name will be added to spec output.

Similar configuration could be done in your pyproject.toml file:

    [tool.pytest.ini_options]
    spec_test_format = "{result} {name}"

or

    [tool.pytest.ini_options]
    spec_test_format = "{result} {docstring_summary}"

spec_success_indicator

spec_success_indicator

You can configure the indicator displayed when test passed.

ini-file

    ; since pytest 4.6.x
    [pytest]
    spec_success_indicator = ✓

    ; legacy pytest
    [tool:pytest]
    spec_success_indicator = ✓

or pyproject.toml

    [tool.pytest.ini_options]
    spec_success_indicator = "✓"

spec_failure_indicator

spec_failure_indicator

You can configure the indicator displated when test failed.

ini-file

    ; since pytest 4.6.x
    [pytest]
    spec_failure_indicator = ✗

    ; legacy pytest
    [tool:pytest]
    spec_failure_indicator = ✗

or pyproject.toml

    [tool.pytest.ini_options]
    spec_failure_indicator = "✗"

spec_skipped_indicator

spec_skipped_indicator

You can configure the indicator displated when test is skipped.

ini-file

    ; since pytest 4.6.x
    [pytest]
    spec_skipped_indicator = »

    ; legacy pytest
    [tool:pytest]
    spec_skipped_indicator = »

or pyproject.toml

    [tool.pytest.ini_options]
    spec_skipped_indicator = "»"

spec_ignore

spec_ignore

Comma-separated settings to ignore/hide some tests or output from from plugins like FLAKE8 or ISORT. Any test which contain provided string will be ignored in output spec.

ini-file

    ; since pytest 4.6.x
    [pytest]
    spec_ignore = FLAKE8

    ; legacy pytest
    [tool:pytest]
    spec_ignore = FLAKE8

or pyproject.toml

    [tool.pytest.ini_options]
    spec_ignore = "FLAKE8"

spec_indent

spec_indent

ini-file

    ; since pytest 4.6.x
    [pytest]
    spec_indent = "   "

    ; legacy pytest
    [tool:pytest]
    spec_indent = "   "

or pyproject.toml

    [tool.pytest.ini_options]
    spec_indent = "   "
