 Collection<PostDiscoveryFilter> postDiscoveryFilters)

Method Details

discover

public LauncherDiscoveryResult discover(LauncherDiscoveryRequest request,
 String phase)

Discovers tests for the supplied request in the supplied phase using the configured test engines.

Applies engine filters and post-discovery filters and prunes the resulting test tree.

discoverEngineRoot

private TestDescriptor discoverEngineRoot(TestEngine testEngine,
 LauncherDiscoveryRequest discoveryRequest)

applyPostDiscoveryFilters

private void applyPostDiscoveryFilters(Map<TestEngine,TestDescriptor> testEngineDescriptors,
 List<PostDiscoveryFilter> filters)

populateExclusionReasonInMap

private void populateExclusionReasonInMap(Optional<String> reason,
 TestDescriptor testDescriptor,
 Map<String,List<TestDescriptor>> excludedTestDescriptorsByReason)

logTestDescriptorExclusionReasons

private void logTestDescriptorExclusionReasons(Map<String,List<TestDescriptor>> excludedTestDescriptorsByReason)

prune

private void prune(Map<TestEngine,TestDescriptor> testEngineDescriptors)

Prune all branches in the tree of TestDescriptors that do not have executable tests.

If a TestEngine ends up with no TestDescriptors after pruning, it will not be removed.

isExcluded

private boolean isExcluded(TestDescriptor descriptor,
 FilterResult filterResult)

acceptInAllTestEngines

private void acceptInAllTestEngines(Map<TestEngine,TestDescriptor> testEngineDescriptors,
 TestDescriptor.Visitor visitor)
