+Feature: Text Mood Parsing
+	In order to make sure the dictionary bag-of-words with weightings is parsed without mistakes
+	I am going to pass in a known legal file and request it be parsed and report back a score
+
+	Scenario: Initializing with a symbol
+		Given I start an instance initialized with ':afinn'
+		When I ask the score of 'assfucking'
+		Then the score returned should be '-4'
+
+	Scenario: Initializing with a legit filepath string
+		Given I start an instance initialized with 'dict/AFINN-111.txt'
+		When I ask the score of 'assfucking'
+		Then the score returned should be '-4'
+
+	Scenario: Initialize with a nonexistent filepath string
+		Given I start an instance initialized with 'dict/thisnameshouldneverexist.diggisthebest.justkidding'
+		Then an exception should be thrown
+
+	Scenario: Initializing with a legit filepath string
+		Given I start an instance initialized with 'dict/AFINN-111.txt'
+		When I ask the score of 'darthvaderinaspeedo'
