Organizations have traditionally been concerned about elevated maintenance costs post-software delivery without realizing that these expenses often stem from the low quality of the delivered software. Even minor bugs can lead to significant losses, affecting consistency, efficiency, productivity, and customer satisfaction.
To address this issue, it's crucial to incorporate effective Quality Assurance (QA) processes throughout the entire software development lifecycle, encompassing analysis, planning, development, testing, and deployment. By adopting this approach, products can transition from poor to high quality, resulting in reduced expenditure on human and other resources. This proactive strategy not only minimizes post-delivery challenges but also contributes to overall organizational success.
We employ the following methods to ensure the delivery of our products to end-users is of the highest quality:
1. Test Application Both Manually And Automated:
While there is considerable emphasis on automated testing and its extensive scope, the importance of manual testing persists, driven by the unique capabilities of the human mind and intuition. Although automated testing is acknowledged for its efficiency, strategic integration of both manual and automated testing methodologies is key to achieving optimal QA testing results. Manual testing excels in addressing diverse scenarios and settings, yet for repetitive tests, leveraging test automation tools becomes imperative. It's essential to discern when automation is appropriate, aligning with the specific requirements of the systems in question.
2. Use of CI/CD Pipelines For Testing:
Continuous integration lets developers and QA update small code sections and test them parallelly. We then run test scripts every time the developers update the code. With continuous delivery and integration testing, we can periodically test new updates of our product and its version. This helps minimize the risk of errors by automating critical functionalities such as building, testing, and deployment.
3. Implementing Mass Testing:
Leveraging mass testing is instrumental in enhancing the scalability and performance of our system. By engaging a substantial pool of QA testers concurrently, operating across various devices and conducting thorough cross-browser testing on diverse operating systems, we can achieve efficient and rapid results. Our approach involves a synergistic blend of in-house testing, mass testing, and automated testing to ensure optimal outcomes.
4. Implementing Shift-left Approach:
When the QA team initiates the development of a testing program right from the initial phase of application development, it aligns with the concept of test-driven programming. The shift-left testing approach, rooted in this principle, advocates conducting testing activities at the outset of the development process rather than relegating them to the final stages, as is conventionally practised. To effectively implement the shift-left approach and commence testing early and iteratively, it is imperative to establish a robust testing strategy at the outset, conduct thorough requirements reviews, perform multiple testing cycles, and adhere to the principle that prevention is better than cure.
5. Achieving Quality With Speed:
We should regularly review our QA process efficiency over different stages of the software development lifecycle. We should not let software quality and speed become dependent on each other. We aim to achieve high-quality output by increasing efficiency and reducing costs, human resources and time. One way to achieve quality with speed is to test the code as it’s developed at the beginning and use continuous integration and continuous delivery (CI/CD) after each code update.
6. Prioritizing Risk Management:
We should always be aware of upcoming risks in our QA testing processes. By outlining and assessing the risks, we can control them from the start improve the execution process and mitigate the risks. This can improve our QA activities and deliver a high-quality final product. If we know the risks earlier, we can mitigate them accordingly, reducing the fixating cost later.
7. Regression Testing Of The Product:
The introduction of new code elements can introduce potential errors in features that had previously passed QA testing. To address this challenge, it is essential to conduct thorough testing not only on the newly developed features but also across all the areas that these features can impact. This comprehensive testing approach is commonly known as regression testing, serving as a periodic health check-up for the software. Given its repetitive nature and the need to cover all scenarios, regression testing is typically carried out using automated testing methodologies.
8. Implementation Of Exploratory And Ad hoc Testing:
If there comes a scenario where you don't have any requirements, test plan or test cases. How are you going to test the product as a QA? Here, you must use your QA experience and perform exploratory testing. Ad hoc testing is considered the least formal method based on error-guessing testing. It’s often associated with monkey testing when random tests are executed with some random data to break the system.
9. Using User Personas As A Reference:
In the product development process, user personas play a crucial role in identifying an ideal customer or the typical target user for the product. A user persona is essentially a character embodying the behaviour patterns and goals of our product's intended audience. Within QA teams, the utilization of user personas serves as a strategic approach to pinpointing potential bugs and guiding the testing efforts towards areas that align closely with the expectations and usage patterns of the identified target users.
10. Effective Methodologies:
Effective software QA testing processes and methodologies are instrumental in mitigating costs related to product development, ensuring strict compliance with specified requirements and guidelines.
11. Continuous Monitoring:
It is imperative to consistently monitor and ensure adherence to pertinent standards and procedures throughout the development process by maintaining continuous oversight of QA test practices.
12. Use Of Analytics:
The utilization of predictive analysis proves invaluable in anticipating potential areas of bugs and drawing insights from historical test data. This approach aids in crafting new tests and strategically selecting relevant QA metrics for tracking purposes. Diverse sets of data, encompassing defect data, testing-related data, development data, application data, operational data, and customer usage data, can be instrumental in this predictive analysis process.
13. Covering Maximum Scenarios:
We should use our QA testing methodologies to cover the widest possible range of conditions and scenarios. This might include different devices, operating systems, and user profiles.
