vipentium is a robust and user-friendly Python testing framework engineered to streamline your testing process. It provides a rich set of features to facilitate efficient test creation and execution.

Note

Please always check the documentation on the website for the latest updates

✨ Key Features

• 🔍 Auto Test Discovery: Automatically identifies test files (prefixed with test_), modules, and directories within a specified path, simplifying test organization and execution.
• ⚙️ Parameterized Testing (@parameters): Enables running a single test function with multiple sets of input data. You can provide tuples of arguments or dictionaries of keyword arguments, optionally naming each parameter set for clearer reporting.
• ⏳ Asynchronous Test Support (async/await): Fully supports testing asynchronous Python code written using async and await keywords, ensuring compatibility with modern Python concurrency.
• ⏰ Timeout Control (@timeout): Allows setting a maximum execution time (in seconds) for individual test methods. If a test exceeds this limit, it's automatically marked as failed, preventing indefinite hangs.
• 🔄 Test Retries (@retry): Provides a mechanism to automatically re-run failing tests a specified number of times. This is particularly useful for handling tests that might occasionally fail due to external factors or non-deterministic behavior.
• 💨 Parallel Execution (--parallel, --process): Significantly reduces test execution time by running tests concurrently. The --parallel flag uses threads, while the --process flag utilizes separate processes for better isolation (requires --parallel).
• 🔌 Plugin Architecture: Offers a flexible plugin system that allows you to extend the framework's functionality. You can create custom plugins to hook into various stages of the test lifecycle (e.g., before/after tests, suite start/end).
• 🛠️ Enhanced Fixture Management (@fixture): Introduces a powerful fixture system for managing test dependencies and setup/cleanup operations. Fixtures support dependency injection, allowing test methods to receive required resources as arguments. Fixture scopes (function, session) control their lifecycle.
• 🏷️ Test Filtering with Markers (@mark, --mark): Enables tagging test methods with descriptive labels using the @mark decorator. You can then use the --mark command-line option to selectively run tests based on these markers.
• 🗣️ Verbose Output (--verbose): Provides more detailed output during test execution, including the names of discovered tests, the status of each test (pass/fail), execution times, and any error messages, enhanced with ANSI color codes for better readability.
• 📊 Advanced Reporting (--report-json, --report-html): Supports generating comprehensive test reports in two formats:
  • JSON (--report-json <filename>): Creates a structured JSON file containing a summary of the test run and detailed results for each test.
  • HTML (--report-html <filename>): Generates a user-friendly HTML report with a summary and detailed test results presented in a web browser.

Enhance your Vipentium testing workflow by enabling Trello integration! With this feature, every test failure is automatically logged as a Trello card—making it easier than ever to track and resolve issues.

1. Create a .env File 📄

In the root directory of your project, create a file named:

.env

2. Add Your Trello Credentials 🛡️

Open the .env file and add the following lines (replace the placeholders with your actual credentials):

TRELLO_KEY=your_trello_api_key_here
TRELLO_TOKEN=your_trello_api_token_here
TRELLO_LIST_ID=your_trello_list_id_here

• TRELLO_KEY: Your unique Trello API key.
• TRELLO_TOKEN: Your Trello API token.
• TRELLO_LIST_ID: The ID of the Trello list where new cards will be created for test failures.

4. Setting Up Environment Variables in PowerShell 🚀

If you run your tests using PowerShell, manually set the Trello environment variables by following these steps:

1. Open PowerShell: Launch PowerShell via the Start Menu or your preferred method.

2. Set the Environment Variables: Run the following commands (replacing the placeholders with your actual credentials):

   $env:TRELLO_KEY = "your_trello_api_key_here"
   $env:TRELLO_TOKEN = "your_trello_api_token_here"
   $env:TRELLO_LIST_ID = "your_trello_list_id_here"

3. Verify the Variables (Optional): Check that they’re set correctly by running:

   echo $env:TRELLO_KEY
   echo $env:TRELLO_TOKEN
   echo $env:TRELLO_LIST_ID

## 🧪 Writing Test Cases

1.  **Test File Naming:** Name your test files with the prefix `test_` (e.g., `test_utils.py`).
2.  **Test Class Definition:** Create classes that inherit from the `TestCase` base class provided by vipentium.
3.  **Test Method Definition:** Define individual test methods within your test classes. These methods must start with the prefix `test_` (e.g., `test_calculate_sum`).
4.  **Assertions:** Use the `assert_equal(a, b)` method provided by the `TestCase` class to compare expected and actual results. You can also use standard Python `assert` statements.
5.  **Decorators for Enhanced Testing:**
      * `@parameters(*args, **kwargs)`: Apply this decorator to a test method to run it with multiple sets of arguments. You can provide individual tuples or a list of tuples. For named parameters, use a dictionary with keys `"args"`, `"kwargs"`, and optionally `"name"`.
      * `@timeout(seconds)`: Decorate a test method to set a maximum execution time in seconds.
      * `@retry(times)`: Decorate a test method to specify the number of times it should be automatically retried upon failure.
      * `@mark(*tags)`: Decorate a test method with one or more marker tags (strings).
      * `@fixture(scope="function"|"session")`: Decorate a function to define a test fixture. The `scope` argument determines the fixture's lifecycle.

<!-- end list -->


## 🚀 Usage Guidelines

### 🗂 Test File Naming

- **Naming Convention:**  
  Name your test files with the prefix `test_` (e.g., `test_utils.py`). This allows vipentium to automatically discover them.

### 🏗 Test Class Definition

- **Inheritance:**  
  Create test classes by subclassing the `TestCase` base class provided by vipentium. For example:

```python
from vipentium import TestCase

class TestMyFunction(TestCase):
    ...

📝 Test Method Definition

• Method Naming:
  Define individual test methods with names starting with test_ (e.g., test_calculate_sum).

• Assertions:
  Use the built-in assertion method assert_equal(a, b) to compare expected and actual results.
  You can also use standard Python assert statements if needed.

🎯 Decorators for Enhanced Testing

• @parameters(*args, **kwargs)
  Run a test method with multiple sets of arguments. You can supply individual tuples or a list of tuples. For named parameters, use a dictionary with keys "args", "kwargs", and optionally "name".

• @timeout(seconds)
  Set a maximum execution time for a test method.

• @retry(times)
  Automatically retry a test method upon failure a specified number of times.

• @mark(*tags)
  Decorate a test method (or class) with marker tags (strings) to help organize and filter tests.

• @fixture(scope="function"|"session")
  Define reusable test setup functions:

  • function: A new instance is provided for each test.
  • session: The fixture is shared across all tests in a test session.

Example Usage

from vipentium import TestCase, parameters, mark, fixture

@fixture(scope="function")
def simple_list():
    """A simple list fixture."""
    return [1, 2, 3]

@fixture(scope="session")
def shared_resource():
    """A shared resource fixture available for the entire session."""
    print("\nSetting up shared resource...")
    data = {"message": "Hello from shared resource"}
    return data

@mark("basic")
class TestBasicOperations(TestCase):
    def test_addition(self):
        self.assert_equal(2 + 2, 4)

    def test_string_concat(self):
        self.assert_equal("hello" + "world", "helloworld")

    def test_list_length(self, simple_list):
        self.assert_equal(len(simple_list), 3)

    def test_shared_message(self, shared_resource):
        self.assert_equal(shared_resource["message"], "Hello from shared resource")

@mark("math")
class TestMathFunctions(TestCase):
    @parameters((5, 2, 7), (10, -3, 7), (0, 0, 0))
    def test_add_parameterized(self, a, b, expected):
        self.assert_equal(a + b, expected)

    def test_division(self):
        self.assert_equal(10 / 2, 5)

    def test_float_equality(self):
        self.assert_equal(3.14, 3.14)

@mark("list_operations")
class TestListManipulation(TestCase):
    def test_append(self, simple_list):
        simple_list.append(4)
        self.assert_equal(simple_list, [1, 2, 3, 4])

    def test_pop(self, simple_list):
        popped_item = simple_list.pop()
        self.assert_equal(popped_item, 3)
        self.assert_equal(simple_list, [1, 2])

    def test_contains(self, simple_list):
        self.assert_equal(2 in simple_list, True)
        self.assert_equal(5 in simple_list, False)

🔌 Extending with Plugins

vipentium's plugin system allows you to customize and extend its behavior. To create a plugin:

1. Create a class that inherits from the Plugin base class provided by vipentium.
2. Override the available hook methods (before_test, after_test, on_start_suite, on_end_suite) to implement your desired actions.
3. Register your plugin using the register_plugin() function.

from vipentium import Plugin, register_plugin

class CustomReportPlugin(Plugin):
    def after_test(self, test_name, test_class, method_name, parameters, success, message, duration):
        if success:
            print(f"[CUSTOM REPORT] Test '{test_name}' passed in {duration:.2f}s")
        else:
            print(f"[CUSTOM REPORT] Test '{test_name}' failed: {message}")

def load_my_plugins():
    register_plugin(CustomReportPlugin())

# Make sure to call load_my_plugins() before running your tests.

📊 Reporting

vipentium can generate detailed reports of your test execution:

• JSON Report: A structured .json file containing a summary of the test run (total, passed, failed, duration) and a list of individual test results with their names, status, duration, and any failure messages.
• HTML Report: A human-readable .html file presenting the test summary and detailed results in a well-formatted web page.

Use the --report-json <filename> and --report-html <filename> command-line options to specify the names of the generated report files.
