+### Test
+We are using Pytest](https://docs.pytest.org/en/latest/index.html) for tests. The tests are located in the package 
+`tests` and use the [conventions for python test discovery](https://docs.pytest.org/en/latest/goodpractices.html#test-discovery).
+
+To run the tests just execute:
+
+```
+python3 -m pytest -v
+```
+
+The option `-v` shows which tests failed or succeeded. Have into account that you can also debug each test 
+(test_* files) with the help of an IDE like PyCharm.
+
+#### Coverage
+To check the coverage of the tests execute
+
+```bash
+ coverage run -m pytest -v
+```
+
+To get a report table 
+
+```bash
+ coverage report
+```
+
+To get a full report in html
+```bash
+ coverage html
+```
+Then check in the [htmlcov/index.html](./htmlcov/index.html) to see it
+
+If you want that previously collected coverage data is erased, you can execute:
