nixes / trip-calc-challange Goto Github PK

The project is structured as follows:

• src/main/java/org/nixes/ contains the source code
• src/test/java/ contains the tests

• expected-trips-full.csv - The hand executed expected results when following all rules and assumptions
• taps.csv - The input file provided in the task description
• trips.csv - The output file generated by this program

Depends on:

• a java 21 JDK.
• Apache Maven

mvn clean install

Run 'TripProcessCommand' with an input taps.csv in the working directory.

java -cp target\lp-trip-calc-1.0-SNAPSHOT.jar org.nixes.TripProcessCommand

mvn test

• The input file is in the correct format
• The input file is in the working directory
• The input file is named taps.csv
• The case of fields in the input file is consistent with the example provided in the task description
• The fare rule is as per the example provided in the task description
• Fare rules do not change during the course of processing a file.
• Cancelled/incomplete trips use the same from and to StopId
• Cancelled/incomplete trips use the first DateTimeUTC as both the Started and Finished values
• Assumed the names of the various trip statuses are "COMPLETED", "INCOMPLETE", "CANCELLED". Only COMPLETED was provided.

• The DurationSecs in the example output seems incorrect. The difference in mins between the Started and Finished times is 5 mins which is 300 seconds. The originally provided output says 900 seconds.
• The started and finished times in the example output do not match the relevant tap ids in the input taps.csv file
• There are some cases of tap offs without tap ons in the example data. I have assumed that these should be considered as incomplete trips. But this would need to be confirmed with the business.
• What is the cause of these isolated tapOffs, is there a data quality/consistency issue?
