This is because the pre-installed fonts differ between the environment where you recorded the scenario (your PC) and the test execution environment.
Even if a specific font is specified in the display settings (CSS) of the web application, if that font does not exist in the test execution environment, another font installed in the environment will be automatically applied.
Notes
You cannot add custom fonts or specify a particular font for Autify's test execution environment.
Please note that you can verify the configured font information by using a JS Step to inspect the style of the target text element.
If needed, please use the Confirm an element has style snippet.
