Image Upload Testing is a process used to ensure that the image upload functionality of an application or website works correctly under various conditions. This testing involves verifying that users can successfully upload images, that the images are handled appropriately by the system, and that any potential issues related to security, performance, and user experience are addressed. Image upload testing is essential in applications where users need to upload photos, such as social media platforms, e-commerce websites, and content management systems.


Test Cases for Image Upload:


Below is a list of 150 test cases for image upload:
