4590363806 Added Pytests for Decission Tree mean_squared_error method (#1374)
* Added Pytests for Decission Tree

Modified the mean_squared_error to be a static method

Created the Test_Decision_Tree class
Consists of two methods
1. helper_mean_squared_error_test: This method calculates the mean squared error manually without using
numpy. Instead a for loop is used for the same.
2. test_one_mean_squared_error: This method considers a simple test case and compares the results by the
helper function and the original mean_squared_error method of Decision_Tree class. This is done using asert
keyword.

Execution:
PyTest installation
pip3 install pytest OR pip install pytest

Test function execution
pytest decision_tree.py

* Modified the pytests to be compatible with the doctest
Added 2 doctest in the mean_squared_error method
For its verification a static method helper_mean_squared_error(labels, prediction) is used
It uses a for loop to calculate the error instead of the numpy inbuilt methods
Execution
```
pytest .\decision_tree.py --doctest-modules
```
