What is the most efficient way to test a strategy?

Heyo, I have been trading for a little under a year and wanted to get more serious about the actual testing of my strategy, I have placed hundreds of backtests on tradingview but I am curious if there is a more efficient way to test different variants of the strategy or new rules and such.

Since AI came I have been playing around with letting Claude backtest my strategy on past pricedata but I am unsure of it’s actual results and reliability. What do you guys use to do masstesting to see which variant of a strategy has the best results. (Not price results necessarily but drawdown and such). Is it just by sitting in front of the charts and on say tradingview or is there some website I don’t know about or so?

Happy for any input you guys have or any ideas to make it more efficient. I find the analysis being quite tedious but still happy to do it. Entry chart, exit chart, potentially some type of trade management during the trade, some note about the larger trend and grading of the setup can take very long which is why I am asking.. thank you in advance!:)
