The pytest-pyspec plugin provides semantics to the pytest output. It transforms the pytest's output into a result similar to the RSpec.

The default pytest output is like the following:

test/test_pytest.py::TestFunction::test_use_test_name PASSED
test/test_pytest.py::TestFunction::test_use_the_prefix_test PASSED
test/test_pytest.py::TestFunction::test_use_the_prefix_it PASSED
test/test_pytest.py::TestFunction::WithDocstring::test_use_docstring PASSED

The pytest-pyspec transforms the output into the following:

A function
  ✓ use test name
  ✓ use the prefix test
  ✓ use the prefix it

A function
  with docstring
    ✓ use docstring

You just need to prefix your test case classes with:

• describe / test to represent objects
• with / without to represent context

And prefix your tests with:

• it / test to represent objects

The following is a sample test that generates the previous tests` output.

class TestFunction:
    def test_use_test_name(self):
        assert 1 == 1
    
    def test_use_the_prefix_test(self):
        assert 1 == 1
    
    def test_use_the_prefix_it(self):
        assert 1 == 1

    class WithDocstring:
        def test_use_docstring(self):
            assert 1 == 1

Moreover, you can use a docstring to overwrite the test description. The following tests have the same output as the previous tests:

class TestA:
    """ Function """
    def test_1(self):
        """ use test name """
        assert 1 == 1
    
    def test_2(self):
        """ use the prefix test """
        assert 1 == 1
    
    def test_3(self):
        """ use the prefix it """
        assert 1 == 1

    class TestB:
        """ with docstring """
        def test_4(self):
            """ use docstring """
            assert 1 == 1

The following test sample:

import pytest

class DescribeHouse:
    def it_has_door(self):
        assert 1 == 1
        
    class WithTwoFloors:
        def it_has_stairs(self):
            assert 1 == 1

        def it_has_second_floor(self):
            assert 1 == 1

        def it_has_third_floor(self):
            assert 1 == 2

Generates the following output:

test/test_sample.py 

A house
  ✓ has door

A house
  with two floors
    ✓ has stairs
    ✓ has second floor
    ✗ has third floor
