8 Ways to Improve Software Testing

    Software Testing tips - Softwarecosmos.com

    Software testing is such an important part of the development process. As developers, we want to build high quality products that users love. But that’s really hard to do if we don’t take the time to thoroughly test our work.

    That’s why in recent years, there’s been a huge rise in agile testing methodologies. Rather than testing just at the end of a project, agile encourages testing continuously throughout development. And the results speak for themselves – projects using agile are able to catch and fix bugs much earlier.

    The reality is, compressing all your testing to the final stages just doesn’t work. Bugs found late are way more expensive to fix. And it means your users are more likely to encounter issues when they use your product for the first time.

    So in this blog, I wanted to explore some of the fundamentals of building a strong testing practice. Things like integrating testing from day one of a project, automating tests whenever possible, and thinking about more than just functionality bugs.

    These basics are so important to lay the groundwork for ongoing testing improvements. Things like adopting new test frameworks or strategies won’t really help if you don’t have solid testing processes already.

    I think if we focus on getting these foundational pieces right, it will really help take our software quality to the next level. And ultimately, provide a better experience for all the people using our apps. So let’s jump into some of these essentials that every development team can start implementing today.

    What is Software Testing?

    Software testing is the process of evaluating a software or system to identify issues and help ensure it meets the technical requirements and functions as expected.

    The goal of testing is to identify any bugs, errors, defects or other issues within the software that could impact the user experience or the system’s functionality. It helps eliminate bugs early in the development process so they don’t reach end users.

    Why Software Testing is Important?

    Testing catches bugs early and saves money. Issues found during development are significantly less expensive to fix than problems reported by customers after deployment. Early testing prevents costly reworks, support burdens, and potential loss of revenue from frustrated users.

    Thorough testing improves overall quality and user experience. When software is thoroughly tested, users encounter fewer bugs and exceptions. They have a smoother experience with features that work as expected. This enhances user satisfaction and builds loyalty to the product or brand. Customers are less likely to switch to a competitor if they’re happy with quality and reliability.

    Testing also reduces risk. Comprehensive testing plans address security, performance, compatibility and other non-functional requirements. This gives assurance that mission critical systems won’t crash or expose sensitive data when really needed. Banks, hospitals and other organizations rely on software to run safely without interruptions. Extensive testing provides reassurance for serious operations.

    Regression testing is crucial to changing software safely. As new features are added or code is refactored, regression testing ensures nothing was accidentally broken. This gives developers confidence that continued improvements won’t undermine what was already working well. Testing enables productive innovation over the long term life of a project.

    Thorough documentation from testing supports future development and maintenance. Test plans, cases, and results provide a record of how software was expected to work at any point. This benefits new members and helps quickly track down issues later on. Testing supports the ongoing evolution of successful, maintainable projects.

    Planning

    Planning is crucial for any software testing project. Just like other projects, testing requires a well thought out plan to guide the process. Testing is usually handled by quality assurance (QA) teams, but an effective plan involves collaboration from multiple groups.

    The testing needs will vary between different software projects. Because of this, having a customized plan is very important. It helps ensure the testing is addressed properly for that specific project.

    There are two main aspects to consider when planning testing. The first is defining clear goals for what needs to be tested, particularly related to the project requirements. Everyone needs to be on the same page about the objectives of the testing. The second critical part of planning is documentation. The plan details need to be written down so everyone involved understands the approach.

    Proper planning lays the foundation for success. It sets the stage for efficient and effective testing. Some of the key elements that should be addressed and documented in a test plan include:

    • Test scopes – What parts of the software will be tested? Which user stories or features?
    • Test schedules – When will each test phase occur? What are the timelines and deadlines?
    • Resources required – What equipment, tools, staff or others resources are needed?
    • Risks and contingencies – What could go wrong and how will issues be handled?
    • Test design techniques – What methods like exploratory or automation will be used?
    • Reporting structure – How and when will status and results be communicated?

    The exact details needed may vary based on the project size and complexity. But having these core components addressed in the plan helps provide structure and guidance for the testing teams. It gives them a roadmap to follow to help ensure high quality outcomes.

    QA Roles

    Defining QA roles is important, but the structure will vary depending on a project or company’s size. Small development teams may have just a few people filling multiple roles. However, larger organizations benefit from assigning specific responsibilities.

    Even for small teams, outlining typical tasks for roles provides structure and clarity. It helps ensure areas don’t fall through the cracks. Here are some common QA roles and what they involve:

    Software Test Engineer – Responsible for comprehensive testing of the overall system or application. Executes both manual and automated tests across all functionality.

    Test Analyst – Focuses on analyzing requirements to identify test conditions, cases, and data needs. Develops test plans, scripts, scenarios, and documentation.

    Test Automation Engineer – Develops automated test scripts using tools like Selenium or Appium to test frequent functional flows and regressions. Handles script maintenance.

    Software Development Engineer in Test – Works closely with developers to build testing frameworks, tools, and utilities used by the QA team. Integrates testing early in the development process.

    Test Architect – Designs complex test environments and infrastructure. Selects tools to support testing needs. Oversees test data management and environment configurations.

    Test Manager – Creates the overall test strategy and ensures it’s followed. Manages resources, timelines, reporting and the QA team. Acts as liaison between different stakeholders.

    Clearly outlining roles helps match team members’ skills and interests to the right responsibilities. It provides structure for larger teams to stay organized and on track. Overall, predefined roles optimize the testing process regardless of a project or company’s size.

    Effective communication

    Effective communication is extremely important for any team to succeed, but it is especially crucial for development teams working on software. The relationship between developers and end users needs clear communication channels to ensure the right product is being built.

    It’s beneficial for quality assurance (QA) team members to have both testing and development skills. This allows them to better communicate with developers about any issues found. It also gives developers more time to focus on coding by allowing QA to resolve minor problems on their own.

    Teams need formal processes for sharing information. The company or team itself should establish recommended communication channels. Just as important is creating a culture where face-to-face conversations are encouraged. In-person discussions tend to be the most effective way of exchanging ideas and resolving questions.

    Setting aside time for retrospective meetings at the end of each sprint period is valuable. These meetings help improve the workflow by identifying what worked well and what could be improved going forward. It’s a chance for continuous process refinement and planning ahead for new opportunities.

    However, informal personal connections are often underappreciated yet profoundly impact team performance. Getting to know colleagues on a personal level fosters trust and new collaborations. Taking a genuine interest in each other’s lives outside of work promotes stronger relationships. Individual opinions and fresh perspectives should be welcomed in an open environment. This level of cohesion and support ultimately lifts up the whole team to even greater success.

    Overall, both structured processes and unplanned human bonds between teammates are equally vital for optimum cooperation and results. Prioritizing open communication in all forms leads to high functioning teams.

    Report bugs

    Bug reporting is a crucial part of the software testing process. As testers, our job is to ensure a software product works as expected before it is released. During testing, issues or “bugs” will inevitably be found. How we report these bugs makes a big difference.

    The goal of a bug report is to clearly communicate the problem to developers, so they can understand and fix it quickly. Simply documenting that a bug exists is not enough. We need to provide important details to help reproduction and resolution.

    Some key things to include are:

    1. A concise yet descriptive summary of the bug. This gives readers a quick understanding.
    2. Clear steps to reproduce the issue. Developers need to be able to test the bug themselves.
    3. Expected versus actual results. What should happen versus what is happening helps identify the root cause.
    4. Priority level and impact. Is this a minor annoyance or a major crash?
    5. Attachments like screenshots. A picture can say a thousand words for visual bugs.
    6. Potential solutions or workarounds if known. This gives developers a head start.
    7. Environment details like OS, browser etc. Reproduction depends on these factors.

    Documenting bugs well takes time but pays off. Well written, reproducible reports save developers effort and get issues fixed faster. Good communication is key to the process. Our job is to not just find problems, but to report them in a way that enables quick resolution. A polished, clear bug report gets people and products to their destination smoothly.

    Now that we understand the importance of bug reporting, let’s look at some technologies that can help streamline and enhance the process even further. Automation tools, test case management systems and collaborative platforms all hold potential for increasing QA effectiveness.

    Pair Programming

    Pair programming is a collaborative approach where two programmers work together at one computer. One programmer acts as the driver who types code while the other, the observer or navigator, reviews each line of code as it is typed. This allows for real-time code review and catching of bugs or problems early. By having two sets of eyes on the code, more issues are likely to be found during development rather than later during testing.

    This approach has additional benefits as well. Knowledge and experience are easily shared between the pairing partners as they work together. Rotating pairs also helps spread knowledge across the whole development team. Programmers can learn from each other. This cooperative approach also tends to produce cleaner, more readable code since it must pass review by the second programmer as it is written. Overall, pair programming helps improve quality, catch problems early, and increase knowledge sharing within a development team.

    Test Driven Development

    Test Driven Development (TDD) is an agile software development process that revolves around automated testing of functionality. With TDD, developers write automated tests before introducing any new code to define requirements and validate successes or failures.

    The TDD process involves short development cycles where a developer first writes a minimal test case that fails, then writes the code to pass that test, and refactors the code as needed. These short cycles repeat, growing and maintaining a suite of automated tests with each new feature or modification. This test-first approach keeps developers focused on meeting functionality requirements and prevents regression of existing features.

    By writing tests first, developers think through designs and requirements more thoroughly up front. The failing tests also serve as documentation of functionality. Continually running tests with each change also helps guard against bugs through continuous validation. Overall, TDD can help improve quality, reduce costs through early detection of issues, and ensure functionality is always maintained throughout the development lifecycle.

    User Acceptance Testing (UAT)

    In traditional software development methods, user acceptance testing typically occurs late in the project, after development is largely completed. However, with the agile practice of User Acceptance Testing, end users and customers are involved from the very early stages of development.

    While user personas help provide insight into typical customer needs, they cannot fully represent all potential use cases and scenarios that real users may encounter. By delaying user input until the end, many issues may be found that require significant rework late in the project, leading to delays, missed deadlines, and user dissatisfaction.

    Agile UAT brings the end user into the development process from the start. Customers and target users are able to provide feedback on features as they are developed in iterative cycles. This gives developers direct insight into how the intended users will actually interact with and use the system in a real environment. Any gaps between design and practical usage can be identified and addressed quickly.

    Early and ongoing user involvement helps ensure the product is developed to precisely meet customer needs. It reduces risks and prevents major overhauls later on. Changes can be implemented incrementally without excessive rework.

    Overall, Agile UAT results in a better product-market fit and higher user satisfaction. By placing customers at the center of each development stage, rather than just at the end, it leads to more successful delivery outcomes.

    Automated test

    Test automation is gaining widespread adoption due to the significant benefits it provides. Automated tests free up developer and tester time that would otherwise be spent on manual testing repetition. They also increase testing reliability and consistency since automated tests can run anywhere and anytime without human error or variation.

    However, the upfront investment in building an automated test framework is a hurdle, especially for smaller teams with limited budgets. All-or-nothing approaches to automation may not make financial sense in some situations.

    The good news is that teams don’t need to fully automate the entire testing process in order to start reaping rewards. Even automating a portion of tests, such as integration or regression testing, can provide value. Automating only the types of tests that gain the most from repetition is a pragmatic strategy.

    Mixing automated and manual testing combines the benefits of both. Humans are still needed for exploratory and usability testing. But automating other areas like functional validation tests creates testing efficiencies.

    With the availability of free and open source test automation tools, the barriers to entry are lower than ever before. A phased approach to modest automation adoption makes sound business sense for most teams, large or small. Some automation is better than avoiding it altogether due to its proven ability to improve quality and productivity over the long run.

    Exploratory and Ad hoc testing

    Exploratory and ad hoc testing play an important role in software testing by helping to uncover hard-to-find bugs and issues that other test approaches may miss. This is because both methods take a more free-form and creative approach compared to structured tests.

    Exploratory testing can be done at any time during development. Testers use their expertise and intuition to design tests on the fly to probe the software in an open-ended manner. This allows testers to think outside the box and discover new perspectives about how the product may behave. Any issues found are then documented to the developers.

    Ad hoc testing is generally performed as a final check after all other testing is complete. With no pre-defined tests, testers inject random or unusual inputs and scenarios to stress and surprise the software in unexpected ways. This is valuable for discovering hard-to-reproduce bugs lying deep in the code paths.

    While exploratory testing provides more guidance via the testers’ expertise, ad hoc testing takes a purely random approach. Both methods require talented testers to think creatively. And neither method easily documents the test steps for replication purposes.

    Together, these less structured methods complement the more rigorous standardized tests used earlier in development. They help boost quality by finding obscure problems that risk falling through the cracks otherwise. The downside is some bugs found may be difficult to fix permanently without test scripts.

    Overall, exploratory and ad hoc testing play an important final role in exposing flaws in hard-to-test software areas that other methods could miss. Used strategically, they strengthen the full testing process.

    Conclusion

    In summary, establishing a robust software testing practice requires focusing on important fundamentals like planning, defining roles, communicating effectively, and reporting bugs thoroughly. It also means leveraging techniques such as pair programming, test-driven development, and user acceptance testing to embed quality assurance activities throughout the development process.

    While upfront investment is needed, test automation should not be avoided but rather phased in pragmatically to reap rewards from areas like regression testing. Exploratory and ad hoc methods serve as a valuable complement by uncovering hard-to-find issues.

    When these basics are in place as the foundation, teams can continue advancing their testing maturity through modern tools, frameworks and customized strategies. But without solid underlying processes, newer approaches may not produce the intended results.

    The discussed methodologies all work together synergistically to help catch bugs earlier, save costs from rework, and deliver higher quality products that gain user satisfaction and loyalty over time. With testing integrated comprehensively as partners in agile development initiatives, organizations can optimize productivity while mitigating risks to critical systems.

    In the end, following these fundamental principles guides software teams to make testing an everyday priority rather than an afterthought. It transforms quality assurance from a necessary chore into an opportunity for continuous improvement embraced by all.
