Greetings. I have to do a bunch of tests, where the initial set up is quite costly (launching ROS system and a bunch of nodes). Therefore, I don't want to set it up each time before a test (like with the standard setUp function). How can I make it so that the setUp function is called only once overall before ALL tests? (And aditionally, so that the tearDown function is called only once after all tests have run?)
Thank you all in advance, best,
