This ingredient adds the ability to run tests by first filtering the test tree based on the result of a previous test run. For example, you can use this to run only those tests that failed in the last run, or to run only tests that have been added since tests were last ran.
This ingredient is specifically an ingredient *transformer* - given a list of
rerunningTests adds the ability for all of these
ingredients to run against a filtered test tree. This transformer can be
applied as follows:
import Test.Tasty import Test.Tasty.Runners main :: IO () main = defaultMainWithIngredients [ rerunningTests [ listingTests, consoleTestReporter ] ] tests tests :: TestTree tests = undefined
This ingredient adds three command line parameters:
- If specified the results of this test run will be saved to
the log file at
--rerun-log-file. If the ingredient does not execute tests (for example,
--list-testsis used) then the log file will not be updated. This option is not enabled by default. This option does not require a value.
- The path to the log file to read previous test
information from, and where to write new information to (if
--rerun-updateis specified). This option defaults to
- Which filters to apply to the
Tasty.TestTreebased on previous test runs. The value of this option is a comma separated list of the following options:
failures: Only run tests that failed on the previous run.
exceptions: Only run tests that threw an exception on the previous run.
new: Only run tests that are new since the previous test run.
successful: Only run tests that were successful in the previous run.
Multiple options can be combined and will be taken under disjunction - so
--rerun-filter=failures,exceptions will run only tests that failed *or*
threw an exception on the last run.
Defaults to all filters, which means all tests will be ran.
Allow base < 4.11.
Allow base 4.9 for building with GHC 8.0
Supports tasty < 0.12.
Supports base <= 4.9, tagged <= 0.9

Update to work with tasty >= 0.8
TestTreeis filtered using a custom traversal now, rather than a
TreeFold. This gives better guarantees that the
TestTreeis only reduced and that nodes (such as
WithResources) continue to work. The resulting filtered
TestTreenow has the same shape as the original tree, but filtered tests are transformed into
TestGroups with no tests. This is a fairly major change to how the filtering is performed, so this is a new major release, and previous versions are now considered deprecated.
Now supports filtering
TestTrees that use resources.
