Writing New Tests
#include "catch2/catch_test_macros.hpp"
#include "knowhere/index/index_factory.h"
TEST_CASE("Test Description", "[tag1][tag2]") {
// Setup
auto index = knowhere::IndexFactory::Instance().Create(...);
// Test
REQUIRE(index.has_value());
// Sections for sub-tests
SECTION("sub-test 1") {
// ...
}
}
If adding tests for new features, consider updating documentation. See
