It is nothing new if you hear people say Quality is very important when it comes to software development. Everyone knows about it but does everyone cautiously care about developing bug-free software or following best practices for software testing? The answer to this is partial. Because the definition of Software Quality of any application is different for each company or user. Every business, stakeholder, or any entity involved in the process of determining quality will have a different perspective.
As time passes, many technocrats have realized the importance of software quality and have to take essential measures while app development. The roots behind the failure of any applications are very uncertain. This turned out to be one of the most obvious reasons for adapting software testing for your business applications. In this blog post, we will be focusing on all the stringent aspects that contribute to building a software application adhering to all measures of quality assurance.

1. The Concept of Software Quality Assurance
Often, there is this thought of how software quality assurance came into existence and is now a priority for developers. So, this has occurred when the products were failing and there were faulty products sourced in the market. Hence, in the process of SDLC, Software testing was introduced and made a vital part of the Software development process. There are various ways of QA testing such as Unit testing, regression testing, integration testing, smoke testing, functional testing, performance testing, and other types of the quality assurance process. All these testing tasks lead to maintaining product quality in software products in a timely manner.
In order to stand out from the herd, it is important to ensure that the developed application is bug-free and simple to use. As a part of software testing services there are two ways you can do testing- One is manual testing, and the second one is automated testing. The primary reason here is to assure that the developed product goes through all the stages of software testing and delivers a high-performing, scalable and secure application.
If you want to save time and improve efficiency, you can use automated testing as a part of the quality assurance process. There are few types of manual testing that can be integrated with frequent automated tests. When you do Automation testing, it is the most appropriate solution that provides faster results and improves performance.
2. Quality Assurance Best Practices for Software Testing
2.1 Develop QA Goals and Objectives
The process of QA is an integral process. It involves various test cases, test scenarios, and other software testing procedures. When talking about stakeholders, this involves QA and development teams, business analysts, product managers, and other QA team members. Here each member from the QA team is accountable for the testing they performed. You need to build strong accountability within the team so that each one knows the goals that they need to achieve. To establish responsibility, you have to create explicit and well-stated objectives and goals.
Here are some of the types of bugs, QA teams encounter when they start with a strict quality assurance process. Each member of the team will perform different types of testing from unit and integration tests to exploratory testing or functional testing. Here are some types of QA goals that can be set for each QA specialist.
- Check open defects- You must take steps against the open defects which have exceeded and quality assurance steps should be taken
- Code requirement- It needs to ensure that we meet all the code requirements with higher efficiency
- Prerequisite check-This aims to address all types of software requirements that we define at the initialization of project development. Each and every detail must be covered.
- Critical Bugs- This type of bug includes high-risk bugs which can interrupt the software functions and hence, these bugs require more attention than others.
2.2 Define Software Testing Process and Plan
The next step in the process of software testing is the introduction to the test plan. Here you can start with planning your test procedures. develop a roadmap on how to implement sprints. Do the sprint planning and define the short-term goals. This will allow the team to be constantly involved at every scale within the project’s phases and improve quality assurance for your business.
You must plan every minute detail of your project if you truly want it to succeed, and software testing is one of those details. This is why one of the most important QA testing best practices is comprehensive preparation and quality assurance.
Prepare a test plan that contains details of testing, by whom, what resources will be required, when the deadline will be met, what the acceptance criteria will be, and what the current status and test results will be. You can also do test automation with the help of your quality assurance tester.
Another great QA technique worth considering is incorporating testing into a succession of short development cycles.
Agile techniques make sense when building mobile applications because these products generally have rapid development cycles and mobile consumers have massive expectations for functionality, quality, and frequency of updates.
This collaborative method needs communication and collaboration between designers, developers, the QA team, and occasionally even users. To encourage cooperation, you may save the app’s code in a single repository.
Your teams will complete a brief design or development cycle, followed by focused quality assurance and testing phase for the newly introduced feature. Additional regression, security, and stress testing can be performed as necessary. What occurs throughout the subsequent design or development cycle is determined by the conclusion of this phase.
Once you’ve adopted this strategy, leveraging automation will help keep things moving. Test automation accelerates focused testing phases and enables you to move on to the next development cycle within hours or days. Manual tests will need to be scheduled following certain design or development cycles in order to integrate input on the user experience and other critical features of the app.
2.3 Imply Multi-Directional Testing Strategy
One of the most apparent but sometimes overlooked Quality Assurance techniques is to employ a variety of QA types. Don’t limit your testing process to just one or two categories. Perform several methods of testing in order to quickly find various sorts of issues.
You need to motivate your development team to build automatic unit tests so that they can evaluate the quality of their code and correct any issues before sending it to QAs to perform testing. Once you have sent the request, the QA team will start off with smoke testing. In this testing process, they may either confirm that the code is ready to test or return it to the developers for retesting.
When we apply multi-directional testing in software development, this means the QA teams will test all the test cases thoroughly using multiple testing strategies. In the software quality assurance program, the team members will initially check manually if there are any bugs or not. Then they perform all types of testing like regression testing, non-functional testing, user acceptance testing to get the right results from this testing process. After making enormous changes and matching release criteria, regression testing ensures that all functionalities are up to date and work seamlessly.
The last phase here is to do user acceptance testing. Here we test the product as per user needs and analyze it to see if it meets all functional requirements or not.
2.4 Continuous Integration and Continuous Deployment
From the standpoint of the QA team, there are several benefits of continuous integration and continuous deployment. One of its major benefits is to quickly obtain a build that includes the most recent additions or fixes.
Continuous Integration is the technique of automatically and as soon as possible testing any change made to your codebase. Continuous Deployment is the process of pushing changes to a staging or production system. This simultaneously activates Continuous Integration. This improves the process by adding continuous delivery to make this process faster.
Our development team may have many git branches relating to different features over the development cycle, but only one branch includes the most up-to-date code. When the code is modified, the CI tool verifies this branch and generates a new build, which is then shared with the selected diaries.
2.5 Adopt a Two-Tier Approach to Test Automation
Most of the time, this has occurred to companies when there is a major change in their development process. The developer who had made exhaustive changes has now moved to a different project. In such cases, the project suffers a delay. The Quality Assurance team is not aware of what testing tools and QA processes were involved. Hence all the tests need to be performed.
So we introduced a two-tier approach where we applied automation testing tools to augment the testing processes. As a result, Our two-tiered approach is in two directions. Tier one implies every contribution to the codebase. It also enables quick validation of developer changes. We perform it with all sanity tests and ad-hoc testing that takes some extra minutes to complete. But ensures good results. The test process in tier two goes through regression testing. We can schedule it to run at night with added test coverage and more time to test changes. It is a challenging task to choose which tier should perform which type of software QA testing.
2.6 Conduct Risk-based Testing
Risk-based testing is a methodology for detecting the most dangerous hazards throughout the testing process. This technique entails identifying project risks, prioritising them, and arranging the testing process accordingly. This enables quality assurance engineers to focus on the most significant risks that might jeopardise the product’s overall performance.
Advantages for the QA department
By incorporating a risk-based testing strategy early in the software development process, you may ease the code architecture and make the product simpler to test.
When testing engineers take a risk-based approach, they focus on the most likely issues during product use. As a result, it contributes to the reduction of the spectrum of testing operations.
Advantages for the customers
When a QA team uses a risk-based testing strategy, they focus on the functionality that is most prone to errors. This enhances the customer experience. Thus, you may obtain a high-quality product if you lack the resources necessary to test the product’s performance thoroughly.
2.7 Frequent Regression Testing in the Development Process
In the software development lifecycle, there are numerous types of testing that take place. The QA specialists must understand what bugs to report, what information to include in reports, and how to structure reports. It also shows if we need to change the QA testing methods. Conventional methods like black-box testing or white box testing have now changed. There are other additional methods which include load testing, stress testing, and other QA best practices for software testing. In addition, the customer and the QA team must agree on the circumstances of the testing environment and the much-needed frequency of regression testing and retesting.
Not only that, regression testing opens the gates of advantages for both the QA team and customers.
Advantages for the QA department
Regression testing includes documenting the process of performing autotests in detail. This documentation provides system specs, test designs, bug reports, operator findings, and other information pertaining to software. Not just testing engineers but also developers and stakeholders may make use of this information.
Another significant benefit of regular regression testing is that it enables testing engineers to ensure that new product features do not impact the stability of the core programme, which is critical for maintaining a high degree of product quality.
Advantages for the customers
Updates have the potential to introduce flaws into a software product. Regression testing assists quality assurance engineers in reducing the number of problems in a product.
Automated tests enable quality assurance experts to accelerate quality assurance reviews and ease the software upgrade process.
From this extensive blog, we understood all the QA best practices for software testing involved in making high-quality software. You may find multiple quality management tricks in abundance but which one to trust is a matter of intelligence. All you need to do is to draft a test strategy, manage the quality standard and check the product from the user’s perspective. Do it by performing continuous testing and quality control measures. The software team should ensure we meet all the requirements and the developed software product is of higher quality. The more we follow these best practices for software testing, we would save more time in repetitive development procedures.
