Functional Test Refactoring

Automated test scripts are often poorly designed, inefficient, and hard to understand and maintain, i.e., the same issues we found in code. Functional Test Refactoring is a process of enhancing the quality of automated functional test scripts.

Optimize Selenium WebDriver Automated Test Scripts

Working automated test scripts is only the first test step to successful test automation. As automated tests are executed often and the application changes frequently too, it is important that test scripts need to be fast, easy to maintain and read.

• Optimize Selenium WebDriver Automated Test Scripts: Speed
• Optimize Selenium WebDriver Automated Test Scripts: Maintainability
• Optimize Selenium WebDriver Automated Test Scripts: Readability

Why Do Most UI Test Automation Fail?

FACT: not many software engineers (in Test) received proper education or training in test automation, which is unfortunate. Considering this: 30–40% of staff in a software team are usually testers. Programmers and business analysts spend a lot of time performing functional testing as well. However, there are few dedicated Functional Testing courses offered at universities to my knowledge. Therefore, it is not surprising that many wrong decisions on test automation are made due to a lack of knowledge.

(Technical)

1. Wrong choice of automation framework
2. Wrong choice of test syntax framework
3. Wrong test scripting language
4. Wrong choice of test automation tool
5. Don’t know how to design easy-to-maintain test scripts
6. Lack of Efficiency
7. Lack of experience in executing a medium-size regression suite of automated UI tests

(Human)

1. Management under-estimate the effort, especially on test maintenance
2. Tech leads over-estimate their capability in test automation
3. Tech leads are fixated with a particular wrong technologies
4. No access to a real Test Automation Coach

Benefits of Continuous Testing

Continuous Testing (enables software teams to push software updates to production daily, not fake CI/CD talks. Check out “Continuous Integration at Facebook” and AgileWay Continuous Testing Grading) is the heart of the software development process. It benefits all stakeholders of a software project.

Software Design Pattern by Example

Design Patterns are good practices of Object-Oriented (OO) Software Design. Applying appropriate design patterns will help to design your software better. However, design patterns are not easy to master, it was the case for me, and my daughter as well when she started an IT degree at Uni. I wrote a series of articles to help her learn Design Patterns quickly. My approach is to use easy-to-understand exercises, which I believe is an easier way to master design patterns.

• Software Design Pattern By Example: Singleton
• Software Design Pattern By Example: Strategy
• Software Design Pattern By Example: Template Method
