Refactor: Use parameterised testing using jest.it.each

[shivammathur]

jest.it.each reduces the boilerplate test code and improves the readability and maintainability.
Currently config, tools and coverage tests use jest.it.each. The same can be done for utils, extensions and install tests.

Can you please assign this to me? I'll try to put something up for this

[shivammathur]

Awesome, assigned.

@shivammathur I have a draft PR up where I've done for extensions.test.ts. If you can take a look whenever you get time for some early feedback while I work on others and incorporate feedback there as well

[shivammathur]

Great work. I have reviewed it, also please create a different PR for each test file you work on. That will be easier for me to review.

Have raised #516 for install.test.ts

[shivammathur]

Hi @aneeshrelan, will you be working on utils.test.ts as well.

[aneeshrelan]

Yup. I can. But I won't have time this weekend. Next week I can spend some time
