2 Days  

This course is designed for testers and software developers who want to learn how to test mainframe software at the unit and system levels.

The course covers both functional and structural testing, with numerous examples and templates. The processes and techniques taught in the course are reinforced with examples and exercises based on mainframe software development processes, tools and languages.

You will learn the terminology, process, and challenges of testing in the real world.

As a result of attending this seminar, you should have a good working knowledge of unit testing and what it takes to design and conduct an effective unit test of mainframe software.
