separate test module

[goswami-rahul]

Since we now have tests in most of the algorithms, I think it is a good idea to have a separate test_module.py file in each module. We can move all the tests from one module to it, and any further algorithms must have their tests in this file. It will make the repo easy to manage.
@keon what do you think? I can start working on this.

The problem is that we have not in all projects unit tests. Many projects (that I have see) have simple tests with the print function that prints something on the console. The idea with the central test-file sounds good.

[goswami-rahul]

yeah those print statements need to be changed to tests too.
But there is one disadvantage in moving tests to separate file, that the tests at the same place can also help viewers understand the algorithms better.

@goswami-rahul I will jump in.

@goswami-rahul @keon
I will test the module maths. I add a file test_module.py with all tests.

@christianbender I would wait for starting work on this until @keon approves on this issue.

[christianbender]

@goswami-rahul OK, I will wait. Thanks for the notice

[christianbender]

@danghai At the moment I pause on my work on this task. Because we don't have an approval.

@christianbender

sorry for the late reply :(
As the repo gets larger, separating test code may be more scalable.
Let's give it a shot and see if it works better!
