How to run tests from a specific directory (only system tests or features specs)?

To run only tests from a specific directory with knapsack_pro gem you need to set environment variable KNAPSACK_PRO_TEST_FILE_PATTERN.

Please ensure your pattern matches individual test files (there is ending like _spec.rb or _test.rb in the pattern name). For instance to run tests from system directory use:


KNAPSACK_PRO_TEST_FILE_PATTERN="spec/system/**/*_spec.rb"

Otherwise, you will match the whole directory (invalid pattern example: KNAPSACK_PRO_TEST_FILE_PATTERN="spec/system/*" - bad because of low granularity). We want to split test files across parallel CI nodes with high granularity by individual test files instead of splitting by directories.
