+/**
+ * Defines a test for the family of CFFT transforms.
+ *
+ * The family of CFFT transforms includes:
+ *
+ * - arm_cfft_radix4_xxx
+ * - arm_cfft_radix2_xxx
+ * - arm_cfft_mag_xxx
+ *
+ * Where xxx can be f32, q31, or q15.
+ *
+ * @param fn_specifier Allowed values: radix4, radix2, mag.
+ * @param type_suffix Allowed values: f32, q31, q15.
+ *
+ * @param config_suffix Used to differentiate test names based configuration
+ * (in this case whether the ifft_flag is set or not.)
+
+ * @param comparison_interface Macro name used to compare reference and fut
+ * outputs.
+ *
+ * @param output_tpe The type of variable contained in the output
+ * (e.g. float32_t, uint32_t, etc).
+ *
+ * @param ifft_flag Determines whether the arm_cfft_instance_xxx is configured
+ * for an inverse FFT.
