Thought Process

• First thing I decided to do is get my code working. So whatever Idea I thought of I jump started with that.

• Then I realised for some valid cases circular dependency error was raised.

• So I decided to validate the Input first and then just order them.

• Self dependency validation was straight forward.

• circular dependency error was a little bit tricky. So I decided to put a check for each job, where a loop runs until dependency cycle for a job ends. e.g. a => b => c => d => nil. So at d dependency cycle ends and if any of the jobs gets repeated I will raise an circular dependency error.

• I have added test cases also for all the given scenarios.

• I have added a main.rb file which contains the steps to run the project.

How to run the project

• Input accepted is an comma separated string, e.g. - "a =>, b => c, c => d"
• go to main.rb and update the input string to desired input string.
• Once correct input is given just run ruby main.rb
• The above command will raise an error if there is self or circular dependency
• Exceptions raised are Exceptions::SelfDependencyError, Exceptions::CircularDependencyError

How to run test cases

• To run test cases first make sure minitest is installed in your system. To install run gem install minitest
• once minitest is installed run ruby tests/job_processor_test.rb to run the test cases
