Mastering Web Testing

Course:  WATEST
Duration:  3 Days
Level:  I
Course Summary

While many of the traditional concepts of software testing still hold true, Web sites and Web applications have a different risk profile to other, more mature environments. A typical Web tester now has to deal with shorter release cycles, changing technology, complex hardware and software platforms and an anticipated user base which is uncontrolled and may run into millions. Many testers and test managers are being asked to make the transition from testing traditional client/server, PC, and/or mainframe environments to testing Web sites and applications

The scope of this course covers Web technology, Web architecture and communications, the testing of functional and non-functional requirements such as usability and includes the complex testing activities of performance and security.
