Functional testing is carried out to verify that each feature of the software functions as intended, as per customer requirements. It tests overall usability, accessibility, and responsiveness in different environments.
Example: For a banking application, system testing will ensure that the system can handle and process transactions, secure customer data, and generate accurate reports.
Example: In an e-commerce application, one module may handle user registration, and another module might handle the purchasing process. Integration testing will ensure that the user registered through the first module can successfully make a purchase through the second module.
Example: In the same e-commerce application example, E2E testing would involve a user navigating the entire purchasing process, from logging in, adding items to the cart, checking out, confirming payment details, to completing the purchase order.
Type | Focus Point | Example |
---|---|---|
System Testing | Compliance with specific requirements | Testing of handling and processing transactions, securing customer data, and generating accurate reports of a banking application |
Integration Testing | Coherent functionality of system units | Ensuring a registered user can make a successful purchase in an e-commerce application |
End-to-End Testing | Correct application flow from start to end | Monitoring the entire purchase process of a user in an e-commerce application |
While logical unit testing or component testing forms the crux of the agile development process, undeniably, there’s more to the string. By adopting a more holistic approach towards testing that encompasses system testing, integration testing, and end-to-end testing, we can ensure the overall functionality, efficiency, and reliability of a system.
By understanding and implementing these functional testing approaches, you are not only adhering to the core values of the Agile Manifesto, which emphasise value and customer collaboration, but also set a stronger preparation ground for yourself towards the Certified Scrum Professional for Developers (CSP-D) exam. In the final analysis, it rounds off to redefining your comprehension of agile practices and caring about the entire system, rather than its segregate components. Ultimately, the goal is to de-risk any software project through early and continuous feedback, aligning with the very agile principle of our study.
Answer: False
Explanation: Integration testing in agile development is performed continuously, not at the end of the development cycle. It focuses on checking if units of software work well together.
Answer: d) All of the above
Explanation: All these testing practices are commonly used in Agile development. They contribute to realizing user requirements, inter-component interactions, and the product’s actual use.
Answer: False
Explanation: System testing does focus on testing the system as a whole, but it’s not limited to functions and features. It also checks system behavior and aligns it with the system design.
Answer: c) To determine the maximum amounts of users the software can handle
Explanation: This is the aim of performance or load testing, not responsiveness testing. Responsiveness testing primarily aims to ensure that the software responds quickly to changes.
Answer: True
Explanation: Acceptance testing validates that the solution works for the user and verifies whether the system meets the business needs.
Answer: a) Regression testing
Explanation: Regression testing is performed after editing the code to ensure that changes have not produced new faults. Debugging is an element of regression testing.
Answer: False
Explanation: Both exploratory and automated testing play vital roles in Agile development. While exploratory testing allows for additional learning and discovery, automated tests offer efficiency and reliability.
Answer: c) Throughout the entire development process
Explanation: Non-functional testing, which includes security, usability, performance, etc., is vital throughout the Agile development process to ensure that the product meets the necessary standards.
Answer: True
Explanation: Pair testing in agile development enables two individuals to combine their expertise and perspectives to find defects more efficiently.
Answer: c) Load testing
Explanation: Load testing is a type of non-functional testing. It is aimed at understanding the behaviour of the system under a specific load or at the point of saturation. It is not focused on functional behaviour but the performance aspect of the system.

Informative blog, thank you!
Security testing is often overlooked in agile. We use OWASP ZAP for this. What do you use?
Security should be a priority, even in agile. Automating security tests helps catch vulnerabilities early.
OWASP ZAP is fantastic. We also use Burp Suite for more detailed security assessments.
Appreciate the blog post!
Test automation can’t replace manual testing completely. Anyone agrees?
Yes, manual testing is still important for exploratory and usability testing.
Automation saves time but manual testing provides human insights that tools can’t.
Pair programming is another practice that indirectly helps in testing as two minds catch more potential issues.
We find pair programming very effective in catching bugs early in the development phase.
Agreed. Pair programming also improves code quality and knowledge sharing.
Test-Driven Development (TDD) – anyone thinks it’s overhyped?
Once you get used to TDD, you’ll realize how much it can improve code quality.
TDD is not overhyped but requires discipline to be effective.
Thanks for the informative post!
Negative: The blog is too basic. More advanced topics would be appreciated.
Thanks for this post!
Great post. Very helpful.
Can someone suggest a good testing practice for agile development beyond unit tests?
Integration testing is great for detecting issues between components that unit tests might miss.
Have you considered using integration tests? They help ensure that different modules and services work well together.
I find load and performance testing essential for agile development, especially for client-server applications.
Load testing is fundamental for apps facing high traffic. It guarantees the app performs well under stress.
Absolutely agree! We use JMeter for load testing our web applications.
How about Contract Testing? It ensures that services interact correctly. Pact is a great tool for this.
We use contract testing to avoid integration issues. It’s more beneficial in agile environments.
Pact and other contract testing tools are crucial for microservices architecture.
I think Behavior Driven Development (BDD) with Cucumber can align the team’s understanding of the requirements.
Using Gherkin syntax in Cucumber makes scenarios very understandable for everyone involved.
BDD is great for bridging gaps between technical and non-technical team members.
Appreciate the helpful information!
End-to-end testing can be very effective in agile environments. Anyone else using this?
We have been using Selenium for end-to-end testing. It has improved our release quality significantly.
End-to-end tests are a part of our CI/CD pipeline. They catch many issues that are overlooked by other tests.
Exploratory testing can uncover issues unit tests won’t catch. What tools do you use for this?
We combine both manual exploratory tests and automated tools like Testim for better coverage.
Session-based testing works well for us in exploratory testing.
