Colcon test not running gtests

edit

I am busy doing an assignment for school however I am running into an issue. I have a very basic proof of concept to which I have created a test using the google test framework.

When I run colcon test and colcon test-result it says "Summary: 4 tests, 0 errors, 0 failures, 0 skipped". These 4 tests however, aren't my created tests for the package. One of my own created tests is a deliberate fail to check if colcon test-result also shows that it failed, which it did not.

I think there might be an issue with my CMakeLists.txt, but I am not certain and do not have a lot of experience with cmake.

See my code here:

driverobot.hpp

#ifndef DRIVEROBOT_HPP
#define DRIVEROBOT_HPP
#include <memory>
#include "rclcpp/rclcpp.hpp"
#include "std_msgs/msg/float32.hpp"
#include "geometry_msgs/msg/twist.hpp"

using std::placeholders::_1;

class DriveRobot : public rclcpp::Node
{
public:
  DriveRobot();
  float ParseMsg(float msg);

private:
  void topic_callback(const std_msgs::msg::Float32::SharedPtr msg);
  rclcpp::Subscription<std_msgs::msg::Float32>::SharedPtr subscription_;
  rclcpp::Publisher<geometry_msgs::msg::Twist>::SharedPtr publisher_;

};

#endif //DRIVEROBOT_HPP

driverobot_test.cpp

#include "driverobot.hpp"
#include "gtest/gtest.h"

TEST(DriveRobot_test, parse_msg_test)
{
    DriveRobot robot;
    EXPECT_FLOAT_EQ(0.22, robot.ParseMsg(12));
    EXPECT_FLOAT_EQ(-0.22, robot.ParseMsg(-1));
    EXPECT_FLOAT_EQ(0.14, robot.ParseMsg(0.14));
    EXPECT_EQ(0, robot.ParseMsg(0));
}
TEST(Driverobot_test, deliberate_fail)
{
    DriveRobot robot;
    EXPECT_EQ(0, robot.ParseMsg(1));
}

int main(int argc, char **argv)
{
    rclcpp::init(argc, argv);
    ::testing::InitGoogleTest(&argc, argv);
    return RUN_ALL_TESTS();
}
