IoT is a complete web of inter-connected things, which are not free from vulnerabilities and hence must be tested for quality, functionality, and security. Agile Manifesto can be really helpful with user experience (UX) work like planning, execution, and evaluation. Big data testing has gained traction recently within software testing companies, which helps manage terabytes of data which cannot be processed by traditional computing techniques.
