Testing saves time, money, and reputation by preventing post-release failures. It also evaluates, improves, and controls software quality through regression testing and test reports that guide release decisions.
Explore the differences between error, defect, bug, fault, and failure using IceCube theory and human-language explanations, with a discount calculation example to illustrate impact.
Explore the pesticide paradox, noting that repeating the same tests may miss new defects and that risk analysis with various test techniques helps uncover them.
Explore the waterfall model, a sequential development approach with phases (requirements, design, coding, testing, deployment, maintenance), its late testing, potential backtracking, and its documentation advantage.
Explore the difference between Scrum and Kanban in agile development; Scrum uses sprints, velocity, and story points, and a product backlog, while Kanban emphasizes flow with work in progress limits.
Learn to install and launch Wireshark, navigate its interface, capture and filter traffic, apply coloring rules, use expert analysis, view statistics, and export packets for QA testing.
Explore how web cache stores data temporarily in browser memory to speed up page loads, using examples like the Google icon and cached images.
Understand internet cookies, small data files stored on a user’s device that capture language settings and login details. See how cookies drive client-server exchanges and persist preferences across pages.
Explore Chrome DevTools to inspect and edit HTML and CSS, test different screen resolutions and devices, inspect network requests, and debug JavaScript in real time.
Explore BrowserStack's cloud testing platform to run web app tests on real devices and emulators, log bugs to Jira or Trello, and manage test cases and runs.
We compare Bard, Bing AI, and Chat Sonic as top AI alternatives to ChatGPT for software testing, covering user story creation, test cases, code correction, and test data generation.
Explore Xcode fundamentals for testers: install Xcode, navigate its main interface, view device logs, run iOS simulators, test apps, and use instruments for performance analysis.
Hi everyone. This course is about preparing for an interview for a Software Tester, also known as a QA. In most interviews there are two parts, testing your soft skills and technical knowledge, this course is about the second part, the technical part.
The course will be useful for testers:
1. Beginners in software testing, to deepen knowledge of software testing theory
2. Experienced software testers who want to recall the basic knowledge of software testing theory
The main task of the course is to deepen your knowledge of software theory. To help you answer questions clearly and confidently at the interview, we did three things, each answer to the question includes
1. Answer from official literature (standards, certifications, other documents)
2. Answer based on analyzed articles on the Internet (we call it "Human Language")
3. A real-life example to help you understand complex theoretical concepts
The course answers the following questions, which are divided into sections:
Testing theory
What is Testing?
What are software testing objectives?
Why is Testing necessary and important?
What is a bug?
What is the Difference between Error, Bug, and Failure?
What are the 7 Testing principles?
Principle 1. Testing shows the presence of defects, not their absence
Principle 2. Exhaustive testing is impossible
Principle 3. Early testing saves time and money
Principle 4. Defects cluster together
Principle 5. Beware of the pesticide paradox
Principle 6. Testing is context-dependent
Principle 7. Absence-of-errors is a fallacy
