This is a common scenario when you want to use those constants in your setup and teardown methods, especially when organizing tests in a more complex structure. In this guide, we will walk you through a clear and practical solution to accomplish this. The Problem Assume you have multiple test files, and each contains a constant that you want to use within your conftest.py file. For instance, here are two example test files: Example Test Files test_01.py [[See Video to Reveal this Text or Code Snippet]] test_02.py [[See Video to Reveal this Text or Code Snippet]] You want to use TEST_NAME in your conftest.py when performing setup and teardown operations. Let's discuss how to achieve that. The Solution To access the TEST_NAME constant from your test files in conftest.py, you can make use of Python's dynamic import capabilities. Here’s a step-by-step breakdown of how to implement this. Step 1: Modify Your conftest.py In your conftest.py, you will define a fixture that can access the test name from each file dynamically. Here’s the Code: [[See Video to Reveal this Text or Code Snippet]] Step 2: Explanation of Each Part import importlib: This imports the importlib module, which provides a way to import modules programmatically. request.node.module: This retrieves the module name of the currently executed test. str(request.node.module).split("'")[1]: This extracts the module name as a string. importlib.import_module(module_name): Dynamically imports the module based on the module name from which the current test is being executed. test_name = test_module.TEST_NAME: This line accesses the TEST_NAME constant from the imported test module. Step 3: Utilizing the Fixture in Your Tests You can use the class_setup_teardown fixture in your tests to ensure the setup and teardown operations include the relevant test name. [[See Video to Reveal this Text or Code Snippet]] Conclusion Accessing constants like TEST_NAME from your test files in conftest.py can significantly enhance the organization and clarity of your testing framework. By dynamically importing your test modules, you can easily utilize constants for setup and teardown, making your test suite more robust and maintainable.
