Testing also helps identify and fix issues early in the development cycle, reducing the risk of costly errors and negative reviews post-launch.

• Testing can be done only after the app is launched to gather user feedback

• Mobile App Testing is optional and not necessary for app development

What are the advantages of Cross-Platform Development for mobile apps?

• Inconsistent user experience, longer development time, difficult debugging
