Web Software and Performance Testing

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

Many testers make huge efforts to test the functionality of Web sites working to tight deadlines with only limited test staff and equipment. The site is released to production and the features work. However, response times are slow in live operation and the site cannot handle peak loads. In addition, the site isn?t robust and cannot routinely recover from errors.

If you?ve already been there, or don?t want to go there, this course goes beyond the basics of functionality testing to ensure that your site works in its "live" production environment before users discover problems.
