tresto 0.1.0

Python unit testing integrated with Trello, providing visualization of project status, ideal for test-driven development

Tresto

Tresto is a Python library that integrates with Trello to provide advanced functionality for unit testing. With Tresto, you can create Trello cards for each test automatically, and these cards will be moved to the appropriate list based on the test results. This makes Tresto an ideal tool for test-driven development, as it provides a convenient and visual way to monitor the progress of your tests.

Installation

You can install Tresto using pip:

pip3 install tresto

Usage

Using Tresto is easy. Simply create a TrestoTestCase and write your tests as you normally would. However, you will need to set up your Trello API key and token as environment variables TRELLO_API_KEY and TRELLO_API_TOKEN.

from tresto import TrestoTestCase

def test_hello_world():
    assert hello_world() == "Hello World"

class TestHelloWorld(TrestoTestCase):
    auto_create_board = True
    auto_create_lists = True

    def test_hello_world(self):
        self.add_card(self.passed_list, 'Hello World Test Passed')

        result = hello_world()
        self.assertEqual(result, "Hello World")

        self.move_card(self.failed_list, self.passed_list)

You can then run your tests using the standard Python unittest framework. See the tests/ subdirectory for test_hello_world.py and test_tresto.py - Yes, that's Tresto testing itself:

import os
import unittest
from tresto import TrestoTestCase
from trello.exceptions import ResourceUnavailable


class TestTresto(TrestoTestCase):

    def setUp(self):
        self.card_failed = None
        self.card_passed = None

    def test_1_board_setup(self):
        self.assertIsNotNone(self.board)
        self.assertEqual(self.board.name, self.board_name)

    def test_2_list_setup(self):
        self.assertIsNotNone(self.passed_list)
        self.assertIsNotNone(self.failed_list)
        self.assertEqual(self.passed_list.name, self.test_passed_list)
        self.assertEqual(self.failed_list.name, self.test_failed_list)

    def test_3_add_and_delete_cards(self):
        # Test add_card and delete_card for FAILED List
        card_name_failed = "Test Card for FAILED List"
        self.card_failed = self.add_card(self.failed_list, card_name_failed)
        self.assertEqual(self.card_failed.name, card_name_failed)
        self.card_failed.delete()
        try:
            deleted_card_failed = self.board.get_card(self.card_failed.id)
            self.fail("Card was not deleted")
        except ResourceUnavailable:
            pass

        # Test add_card and delete_card for PASSED List
        card_name_passed = "Test Card for PASSED List"
        self.card_passed = self.add_card(self.passed_list, card_name_passed)
        self.assertEqual(self.card_passed.name, card_name_passed)
        self.card_passed.delete()
        try:
            deleted_card_passed = self.board.get_card(self.card_passed.id)
            self.fail("Card was not deleted")
        except ResourceUnavailable:
            pass

    def test_4_add_and_move_card_between_lists(self):
        card_name = "Test Card for Moving Between Lists"
        card = self.add_card(self.passed_list, card_name)
        self.move_card(card, self.failed_list)

        # Refresh card data
        card.fetch()

        self.assertEqual(card.list_id, self.failed_list.id)
        card.delete()

if __name__ == '__main__':
    unittest.main()
