Adding Testing integration in swift using xctest

Introduction

Welcome to an introduction to how to integrate testing in ios projects. The framework I chose for my project is XCtest which is an automation tool provided by Apple. Use the XCTest framework to write unit tests for your Xcode projects that integrate seamlessly with Xcode's testing. documentation

Setup

Please follow the instruction to set up the XCTest for your Xcode project.

To run the tests in swift

$ swift test

Shortcuts

These shortcuts are essential when writing unit tests in Xcode.

1. Command + U to run all tests.
2. Command + Option + Control + G to run latest test.

Errors encountered

Fixed errors

    if(input.isEmpty){
        print("Error. Please enter input folder or add suffix to file name")
        return
      }

Outcome

Learning from testing is to cover all arguments or other ways possibilities of having errors. While testing helps to come up with all scenarios that can cover all errors. Commits: commits
