# nac-test

A CLI tool to render and execute [Robot Framework](https://robotframework.org/) tests using [Jinja](https://jinja.palletsprojects.com/) templating. Combining Robot's language agnostic syntax with the flexibility of Jinja templating allows dynamically rendering a set of test suites from the desired infrastructure state expressed in YAML syntax.

```shell
$ nac-test -h

 Usage: nac-test [OPTIONS]

```

All data from the YAML files (`--data` option) will first be combined into a single data structure which is then provided as input to the templating process. Each template in the `--templates` path will then be rendered and written to the `--output` path. If the `--templates` path has subfolders, the folder structure will be retained when rendering the templates.

After all templates have been rendered [Pabot](https://pabot.org/) will execute all test suites in parallel and create a test report in the `--output` path. The `--skiponfailure non-critical` argument will be used by default, meaning all failed tests with a `non-critical` tag will show up as "skipped" instead of "failed" in the final test report.

## Installation

Python 3.10+ is required to install `nac-test`. Don't have Python 3.10 or later? See [Python 3 Installation & Setup Guide](https://realpython.com/installing-python/).

`nac-test` can be installed in a virtual environment using `pip`:

```shell
pip install nac-test
```

The following Robot libraries are installed with `nac-test`:

- [RESTinstance](https://github.com/asyrjasalo/RESTinstance)
- [Requests](https://github.com/MarketSquare/robotframework-requests)
- [JSONLibrary](https://github.com/robotframework-thailand/robotframework-jsonlibrary)

Any other libraries can of course be added via `pip`.

## Ansible Vault Support

Values in YAML files can be encrypted using [Ansible Vault](https://docs.ansible.com/ansible/latest/user_guide/vault.html). This requires Ansible (`ansible-vault` command) to be installed and the following two environment variables to be defined:

```
export ANSIBLE_VAULT_ID=dev
export ANSIBLE_VAULT_PASSWORD=Password123
```

`ANSIBLE_VAULT_ID` is optional, and if not defined will be omitted.

## Additional Tags

### Reading Environment Variables

The `!env` YAML tag can be used to read values from environment variables.

```yaml
root:
  name: !env VAR_NAME
```

## Example

`data.yaml` located in `./data` folder:

```yaml
---
root:
  children:
    - name: ABC
      param: value
    - name: DEF
      param: value
```

`test1.robot` located in `./templates` folder:

```
*** Settings ***
Documentation   Test1

*** Test Cases ***
{% for child in root.children | default([]) %}

Test {{ child.name }}
    Should Be Equal   {{ child.param }}   value
{% endfor %}
```

After running `nac-test` with the following parameters:

```shell
nac-test --data ./data --templates ./templates --output ./tests
```

The following rendered Robot test suite can be found in the `./tests` folder:

```
*** Settings ***
Documentation   Test1

*** Test Cases ***

Test ABC
    Should Be Equal   value   value

Test DEF
    Should Be Equal   value   value
```

As well as the test results and reports:

```shell
$ tree -L 1 tests
tests
├── log.html
├── output.xml
├── pabot_results
├── report.html
├── test1.robot
└── xunit.xml
```

## Custom Jinja Filters

Custom Jinja filters can be used by providing a set of Python classes where each filter is implemented as a separate `Filter` class in a `.py` file located in the `--filters` path. The class must have a single attribute named `name`, the filter name, and a `classmethod()` named `filter` which has one or more arguments. A sample filter can be found below.

```python
class Filter:
    name = "filter1"

    @classmethod
    def filter(cls, data):
        return str(data) + "_filtered"
```

## Custom Jinja Tests

Custom Jinja tests can be used by providing a set of Python classes where each test is implemented as a separate `Test` class in a `.py` file located in the `--tests` path. The class must have a single attribute named `name`, the test name, and a `classmethod()` named `test` which has one or more arguments. A sample test can be found below.

```python
class Test:
    name = "test1"

    @classmethod
    def test(cls, data1, data2):
        return data1 == data2
```

## Rendering Directives

Special rendering directives exist to render a single test suite per (YAML) list item. The directive can be added to the Robot template as a Jinja comment following this syntax:

```
{# iterate_list <YAML_PATH_TO_LIST> <LIST_ITEM_ID> <JINJA_VARIABLE_NAME> #}
```

After running `nac-test` with the data from the previous [example](#example) and the following template:

```
{# iterate_list root.children name child_name #}
*** Settings ***
Documentation   Test1

*** Test Cases ***
{% for child in root.children | default([]) %}
{% if child.name == child_name %}

Test {{ child.name }}
    Should Be Equal   {{ child.param }}   value
{% endif %}
{% endfor %}
```

The following test suites will be rendered:

```shell
$ tree -L 2 tests
tests
├── ABC
│   └── test1.robot
└── DEF
    └── test1.robot
```

A similar directive exists to put the test suites in a common folder though with a unique filename.

```
{# iterate_list_folder <YAML_PATH_TO_LIST> <LIST_ITEM_ID> <JINJA_VARIABLE_NAME> #}
```

The following test suites will be rendered:

```shell
$ tree -L 2 tests
tests
└── test1
    ├── ABC.robot
    └── DEF.robot
```

## Select Test Cases By Tag

It is possible to include and exclude test cases by tag names with the `--include` and `--exclude` CLI options. These options are directly passed to the Pabot/Robot executor and are documented [here](https://robotframework.org/robotframework/latest/RobotFrameworkUserGuide.html#by-tag-names).
