Python is typically associated with web and internet development but is an invaluable tool for any test engineer. This course gives the test engineer the ability to use Python comfortably and interact with an embedded platform to show the ease with which Python can make the complicated, trivial. Delegates will gain an understanding of essential programming techniques.
This course introduces the Python 3 language for use by test engineers working with embedded systems and external hardware. The focus is on using Python to automate the testing process, analysis test results, and interact with hardware and external test software. Emphasis is placed on best practices for developing and maintaining Python scripts as well as efficient use of Python data types and OO techniques.
- To provide a solid understanding of the essentials of the Python programming language.
- To give you practical experience of writing Python scripts to automate testing.
- To help you work with test result data and undertake basic numeric data analysis.
Delegates will learn:
- Python 3 syntax, object model and program structure
- Data types including tuples, lists, dictionaries and Numpy arrays
- Reading and writing text and binary files
- Automating the testing process
- Simple numeric data analysis
- Running external programs
- Interfacing to existing C/C++ library code
- Interacting with hardware via serial lines or network sockets
The course is designed for test engineers with experience in at least one
programming or scripting language sufficient to work with if statements and for
Who should attend?
This course should be attended by engineers required to use Python in a testing
role, or those seeking an introduction to Python programming. This course is
suitable for those with limited experience of programming and as a refresher to
bring Python skills up to date.
- Delegate handbook
- Lab solutions
- Bootable USB data-key
Up to 50% of the course is hands-on exercises. Students will develop Python 3
scripts using either Eclipse/pydev or PyCharm and work with exercises based on
real world test scenarios.
