add tests

[nidhaloff]

I'm using mocha and chai to write tests for the package. This issue is great for new comers who want to join the project. You can write more tests to test the functionality. Feel free to work on this or discuss it with me

Hello,
I would like to write tests for Batch Translations and File Translation using Mocha and Chai.
I'd love to contribute to this project. Would you guys still be up for approving/testing with me? Is this issue still relevant?
@nidhaloff @pasagedev
Thanks!
