as_projector()

pp::Projector ppforest2::test::as_projector ( std::vector< types::Feature > v )

inline

Build a Projector from a std::vector<Feature> initializer.

Tests reach for projector vectors a lot — the Eigen::Map → Projector dance reads as line noise at the call site. This helper hides it so tests can write as_projector({1.0F, 0.0F}) and stay focused on the data their assertions depend on.

classification_spec()

TrainingSpec::Ptr ppforest2::test::classification_spec ( )

inline

Default-valued classification spec.

regression_spec()

TrainingSpec::Ptr ppforest2::test::regression_spec ( )

inline

Minimal well-formed regression spec.

Picks regression-compatible strategies (ByCutpoint, MeanResponse, MinSize) since the classification defaults (e.g., PureNode) reject regression mode at validation time.

throws_with()

inline ::testing::AssertionResult ppforest2::test::throws_with	(	std::function< void()> const &	fn,
		std::string const &	needle )

gtest assertion: fn throws a std::runtime_error whose what() contains needle.

Used by JSON-validation tests where the exception message carries the dotted path of the offending field (e.g. "config.pp.lambda: missing required key"). Centralised here so JsonReader, ExportValidation, and per-strategy from_json tests share one helper.

EXPECT_TRUE(throws_with([&] { reader.require<int>("k"); }, "k: missing"));
