+ * @brief 	Template test file
+ * @details
+ * In each test case, the code outside the sections is executed
+ * for EACH section.
+ * The most common macros to perform tests are:
+ *  - CHECK(...): assert expression and continues even if it fails
+ *  - REQUIRE(...): test case fails if assertion fails
+ *
+ *  Tests are generally sturctured in test cases and sections, see example
+ *  below.
+ *
