The document discusses best practices for writing maintainable test automation code, emphasizing that automation code should be human-readable and follow clean coding principles. It suggests avoiding common pitfalls like code repetition and encourages meaningful naming conventions to enhance clarity. The balance between maintaining clean code and managing the cost of refactoring is highlighted as essential for effective test automation.
Writing Maintainable Test Automation
- 1. WRITING MAINTAINABLE TEST AUTOMATION AVOIDING COMMON AUTOMATION PITFALLS
- 2. IS TEST AUTOMATION CODE REAL CODE? SHOULD AUTOMATION CODE BE WRITTEN FOLLOWING THE SAME CONVENTIONS AS PRODUCTION DEVELOPERS WRITING PRODUCTION CODE?
- 4. DOES THAT MEAN WE SHOULD IGNORE ALL CLEAN CODING PRACTICES? OF COURSE NOT
- 5. WHY SHOULD WE BOTHER?
- 6. BUT REFACTORING HAS A COST, TOO
- 7. THE HAPPY MEDIUM • NO NEED TO GET INTO DEEP, TECHNICAL, PROGRAMMING CONCEPTS • ALSO WE DO NOT WANT TO END UP WITH A PROJECT THAT COSTS MORE TO MAINTAIN THAN IT IS WORTH TO EXECUTE • TESTERS CAN START WITH SOME SMALL PRACTICES THAT WORK TOWARD CLEAN, MAINTAINABLE, CODE
- 8. MAKE CODE HUMAN READABLE • CODE IS READ BY HUMANS, NOT COMPUTERS • CODE SHOULD CONVEY INTENT • NAMES SHOULD BE MEANINGFUL • NAMES SHOULD NOT BE ABBREVIATED
- 10. HOW COULD WE MODIFY THIS?
- 11. MAYBE LIKE THIS?
- 12. DRY: DON’T REPEAT YOURSELF • IF YOU FIND THAT YOU DO IT MORE THAN ONCE, PULL IT OUT INTO A SEPARATE METHOD • IF YOU FIND THAT YOU ARE COPYING AND PASTING CODE, CONSIDER WHETHER YOU ARE REPEATING YOURSELF
- 13. WHAT HAPPENS THE NEXT TIME WE WANT TO OPEN THAT EXCEL SPREADSHEET?
- 15. WHAT ABOUT WHEN ANOTHER USER NEEDS TO PUT THEIR OWN PATH IN?
- 17. WHAT ABOUT WHEN WE NEED TO INSERT A SHEET AS SHEET 1 IN THESE EXCEL FILES?
- 19. EVEN BETTER …
- 20. LET’S START THERE • NAME ALL VALUES WITH MEANINGFUL, RELEVANT, HUMAN-READABLE NAMES • DON’T REPEAT YOURSELF
