Test.Tasty.Ingredients.Rerun

Description

This ingredient for tasty testing framework allows to filter a test tree depending on an outcome of the previous run. This may be useful in many scenarios, especially when a test suite grows large.

The behaviour is controlled by command-line options:

--rerun
Rerun only tests, which failed during the last run. If the last run was successful, execute a full test suite afresh. A shortcut for --rerun-update --rerun-filter failures,exceptions --rerun-all-on-success.
--rerun-update
Update the log file to reflect latest test outcomes.
--rerun-filter CATEGORIES
Read the log file and rerun only tests from a given comma-separated list of categories: failures, exceptions, new, successful. If this option is omitted or the log file is missing, rerun everything.
--rerun-all-on-success
If according to the log file and --rerun-filter there is nothing left to rerun, run all tests. This comes especially handy in stack test --file-watch or ghcid scenarios.
--rerun-log-file FILE
Location of the log file (default: .tasty-rerun-log).

To add it to your test suite just replace defaultMain with defaultMainWithRerun or wrap arguments of defaultMainWithIngredients into rerunningTests.
