Adding on to what everyone else has said so far, you very rarely need to test your max even as a pro athlete. If you're serious about strength find a linear program and familiarise yourself with the concept of RPE (rate of perceived exertion or how hard the lift feels). Optimal training for strength gains sits around the RPE 7-8 mark (around 70-80% of your body's maximum capability). Training at that level will let you operate in safe weight levels, without a spotter and then if you want, to test your maxes from time to time when you get a spotter
