Pantherlog test fails with CSV input


When trying to run a test with pantherlog on sample CSV input, the test fails even though the input is correct. 


  1. Check if your input CSV statement has multiple lines
  2. If so, remove the extra line and change your input to just be one single line with your CSV sample event.
  3. Remove the hasHeader: true statement from your schema if it has one.


This issue can occur when you use multiple lines for your CSV input. For example if you have something like:

Panther will treat these 2 lines as 2 separate events, but a test case can only have 1 event. In this case, the first line will be used as the event, and if your first line is just the CSV header line, this will either fail to classify, and/or simply not match your expected result for this test case.
