Mastering Web Testing (MWT)
Course Description
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.
The course is instructor-led with lecture presentations being supported by hands-on practical work using a number of fictitious Web sites, which allow reinforcement of learning and enhances the understanding process. In addition, various testing tools will be demonstrated.
Target Student
The course is designed for software testers, members of QA teams and test managers.
Prerequisites
A basic knowledge of the Internet and software testing. Attendance on the Structured Approach to Software Testing course would be an ideal prerequisite.
Performance-Based Objectives
Upon successful completion of this course, students will be able to:
Understand the different technologies used in Web environments.
Communicate adequately with appropriate technical personnel to ensure that the correct test environments are set up.
Perform a simple risk analysis to identify and prioritise tests.
Create appropriate tests, test cases and test scripts.
Execute tests in a controlled manner using the correct setup conditions and inputs.
Understand the nature, availability and limitations of Web testing tools.
Examine performance requirements and ensure that the requirements are realistic and achievable.
Understand how to test a site™s reliability and scalability prior to release.
Examine a security policy and specify the types of tests necessary to ensure that the requirements contained in the policy are being met.
