 In addition to translating individual commands between Vensim/XMILE and Python, PySD reworks component identifiers to be Python-safe by replacing spaces with underscores. The translator allows source identifiers to make use of alphanumeric characters, spaces, or special characteres. In order to make that possible a namespace is created, which links the original name of the variable with the Python-safe name. The namespace is also available in the PySD model class to allow users working with both original names and Python-safe names.

+Test suite
+==========
+
+Preparing the test suite
+------------------------
+
+In order to run the test:
+
+1. Clone the repo with the --recursive flag (if not done yet).
+2. Potentially create or enter a virtual environment.
+3. Install test dependencies using *pip install -r tests/requirements.txt* or *conda install --file tests/requirements.txt*.
+
+Running the test suite
+----------------------
 
 To run tests:
-```
+
+```shell
 make tests
 ```
 
 To have coverage information:
-```
+
+```shell
 make cover
 ```
 
 To have information of visit lines in HTML files in `htmlcov` folder:
-```
+
+```shell
 make coverhtml
 ```
 
 To run in multiple CPUs (e.g: for 4 CPUs):
-```
+
+```shell
 make command NUM_PROC=4
 ```
+
 where `command` is any of above.
 
+You can also run the test using `pytest`:
+
+```shell
+python -m pytest test/
+```
+
+for running individual test, filtering warnings or some other configurations check [pytest documentation](https://docs.pytest.org).
