+ * @brief Unit tests for N_LogView::LogViewTetraTelegramsParser.
+ *
+ * The parser reads the C++ telegram specification header and exposes the
+ * structs, enums and POD types it found. It is pure logic with no GUI
+ * dependency, so each test feeds it a small specification written to a
+ * temporary file and inspects the resulting model.

+ * @brief Shared entry point for the TetraIF unit test executables.
+ *
+ * GTest::gtest_main provides a main() that neither creates a QCoreApplication
+ * nor bootstraps the NGL root logger. The classes under test do both: they take
+ * a logger reference in their constructor, and NGL::NGLLoggerBootstrap throws
+ * NotCreatedError when the root logger has not been created yet.
+ *
+ * This mirrors tests/gtest_qt_main.cpp, minus the QApplication - none of the
+ * TetraIF unit tests touch widgets.
