### Install Python Requirements for Conan

Source: https://github.com/conan-io/conan/blob/develop2/README.md

Installs the necessary Python packages for running Conan tests. Ensure you are in the root directory of the Conan project.

```bash
python -m pip install -r conans/requirements.txt
```

```bash
python -m pip install -r conans/requirements_server.txt
```

```bash
python -m pip install -r conans/requirements_dev.txt
```

--------------------------------

### Run Conan Help Command

Source: https://github.com/conan-io/conan/blob/develop2/README.md

Verify Conan installation by running the 'conan --help' command. This displays available consumer commands.

```bash
conan --help
```

--------------------------------

### Install Conan in Editable Mode

Source: https://github.com/conan-io/conan/blob/develop2/README.md

Install Conan from source in editable mode using pip. On Windows, 'sudo' is not required. For some Linux distributions, creating a virtual environment 'venv' first is mandatory.

```bash
cd conan-io && sudo pip install -e .
```

--------------------------------

### Run Specific Conan Test

Source: https://github.com/conan-io/conan/blob/develop2/README.md

Executes a specific Conan test case. Replace the example path and test name with the desired test.

```bash
python -m pytest test/functional/command/export_test.py::TestRevisionModeSCM::test_revision_mode_scm -s
```

--------------------------------

### Test File Naming Convention

Source: https://github.com/conan-io/conan/blob/develop2/test/README.md

Test files should be named starting with 'test_' to be discovered by Pytest.

```tree
test
├── README.md
├── conftest.py
├── unittests
│   ├── __init__.py
│   ├── test_mytest.py
│   ...
...
```

--------------------------------

### Configure Artifactory Connection for Tests

Source: https://github.com/conan-io/conan/blob/develop2/README.md

Sets environment variables to connect to a local Artifactory instance for testing. Adjust URL, user, and password as needed.

```bash
export CONAN_TEST_WITH_ARTIFACTORY=1
```

```bash
export ARTIFACTORY_DEFAULT_URL=http://localhost:8081/artifactory
```

```bash
export ARTIFACTORY_DEFAULT_USER=admin
```

```bash
export ARTIFACTORY_DEFAULT_PASSWORD=password
```

--------------------------------

### Run Conan Tests with Artifactory

Source: https://github.com/conan-io/conan/blob/develop2/README.md

Executes Conan tests that require an Artifactory instance. Ensure the necessary environment variables for Artifactory connection are set.

```bash
python -m pytest . -m artifactory_ready
```

--------------------------------

### Clone Conan Repository

Source: https://github.com/conan-io/conan/blob/develop2/README.md

Clone the Conan repository to your local machine. Ensure the directory name is 'conan-io' as other names might cause issues with tests.

```bash
git clone https://github.com/conan-io/conan.git conan-io
```

--------------------------------

### Run All Conan Tests

Source: https://github.com/conan-io/conan/blob/develop2/README.md

Executes the entire Conan test suite using pytest. This command should be run from the root directory of the Conan project.

```bash
python -m pytest .
```

--------------------------------

### Parametrizing Tests with Pytest

Source: https://github.com/conan-io/conan/blob/develop2/test/README.md

Utilize the 'pytest.mark.parametrize' decorator to run the same test logic with different input values.

```python
@pytest.mark.parametrize("use_components", [False, True])
def test_build_modules_alias_target(self, use_components):
    ...

```

--------------------------------

### Test Method Naming Convention

Source: https://github.com/conan-io/conan/blob/develop2/test/README.md

Test functions or methods within test files should be prefixed with 'test_'.

```python
class TestSomeFunctionality:

    def test_plus_name(self):
        client = TestClient()
        conanfile = textwrap.dedent("""
        ...
```
```

--------------------------------

### Marking Tests with Pytest and Tool Markers

Source: https://github.com/conan-io/conan/blob/develop2/test/README.md

Use Pytest markers for built-in functionality and custom tool markers like 'cmake', 'gcc', etc., for tests requiring specific external tools. These should be placed in the 'test/functional' folder.

```python
@pytest.mark.skipif(platform.system() != "Windows", reason="Needs windows for vcvars")
@pytest.mark.tool("visual_studio")
def test_vcvars_priority(self):
    client = TestClient()
    ...
```

--------------------------------

### Set PYTHONPATH Environment Variable

Source: https://github.com/conan-io/conan/blob/develop2/README.md

Configures the PYTHONPATH environment variable to include the current directory. This is essential for the test suite to find Conan modules.

```bash
export PYTHONPATH=$PYTHONPATH:$(pwd)
```

```bash
set PYTHONPATH=.
```
