+Feature: Command-line interface (CLI)
+
+  bio-table has a powerful comman line interface. Here we regression test features.
+
+  Scenario: Test the numerical filter by column values
+    Given I have input file(s) named "test/data/input/table1.csv"
+    When I execute "./bin/bio-table --num-filter 'values[3] <= 0.05'"
+    Then I expect the named output to match "table1-0_05"
