Writing tests would improve our codebase as whole and we will lead to lesser bugs.

Sure, start with model unit testing.

Probably open up a few more issues something more specific like 'Write test for X Model' or 'Improve Integrate Test for Hardware Loan'?

Check out shoulda-matchers it will considerably help you with writing the simple test cases quick.

Once you've written test cases you can integrate it into your CI very smoothly and refactor your code far more confidently.

Since you asked for a few examples take a look at this gist. I do suggest setting up capybara for integration testing as well (and my gist has a few links to good tutorials)
