Training and local execution
mabl uses the Chrome app installed on your local machine for training and local test execution. Visit chrome://settings/help to check which version of Chrome you are using.
To ensure more consistent results between Trainer, local, and cloud runs, we recommend keeping your local Chrome app up to date.
While Chrome is the only supported browser for training and local execution, it is possible to update the browser path to a different chromium browser, such as Microsoft Edge.
