9 Software Testing Mistakes Testers Should Avoid
The software testing lifecycle is long and complex. Despite the careful steps testers take, mistakes can occur at various stages and can impact the overall quality of the software under test. These mistakes can not only delay the testing lifecycle but also impact user experience, business reputation, and customer satisfaction and loyalty. Let’s look at the top software testing mistakes testers should avoid:
1. Inadequate Test Planning
While software testing is essential for identifying bugs and enhancing quality, the rush to market often leads to shorter testing cycles. Insufficient test planning can have far-reaching repercussions such as -
- Poor software design: Poor test planning leads to a limited understanding of the products’ usage. If testers are not able to prioritize features for early testing, it leads to poor software design.
- Missed deadlines: Teams that do not devote sufficient time to test planning find themselves overshooting deadlines. Not documenting timelines, schedules, and resource requirements leads to costly delays in deployment.
- Limited understanding of roles and responsibilities: Insufficient test planning also leads to unclear roles and responsibilities. It restricts visibility while also diluting the transparency needed to adequately test the software.
Solution: Clearly define test objectives
Since test planning lays the foundation of any software project, it is important for teams to ensure sufficient test planning. Make sure to clearly define test objectives, design the test strategy, and plan resource allocation. Also, take time to set up the test environment and finalize the tools you will be using.
2. Not Focusing on Quality of Test Case Design
Poor test case design is a leading cause of software failing to meet the requirements. When teams hurry up the test case design process, they face several challenges along the way, such as -
- Poor quality product: Test cases, when not designed properly, impact overall software functionality and performance. Teams fail to ensure software meets requirements, which impacts end-user satisfaction.
- Limited defect detection: Poorly designed test cases fail to uncover defects or bugs in the software. This can lead to costly crashes, security vulnerabilities, and other unexpected behaviors.
- Ineffective regression testing: Poor test case design also leads to ineffective regression testing. As developers develop new features or changes to existing code, they can cause unintended side effects or break existing functionality.
Solution: Design test cases properly
A robust test case design can completely transform software development outcomes. To do this successfully, you must determine the scope, be sure of the requirements, and also be clear about design specifications. You should also create test cases for every software requirement and ensure the product meets all specifications.
3. Over Relying on Manual Testing
Manual testing, although critical for certain types of testing, like UI testing, is not practical. In today’s era, manual testing brings about several challenges, including -
- Error-prone: Manually testing software applications across different environments and operating systems is extremely error-prone. As systems get increasingly complex, the errors only multiply in number and magnitude.
- Poor coverage: In manual testing, testers test software based on their individual skills and experience. This leads to poor coverage and the risk of some functions not being tested fully or at all.
- Time and resource-intensive: Manual testing demands substantial time and resources. This delays release schedules while also causing substantial stress and frustration for testers.
- Expensive: Manual testing is also extremely expensive. While teams may save upfront costs on automated tools, in the long run, it might lead to expensive headaches.
Solution: Embrace a modern test automation platform
Investing in a modern test automation platform is a great way to overcome manual testing challenges. A no-code platform like ACCELQ, for example, can enable teams to automate crucial testing tasks. You can quickly spin up new test cases and ensure comprehensive and continuous testing of the software.
4. Poor Communication
In the hybrid work model, testing teams work from different locations and time zones. Working in silos and not interacting on a frequent basis can impact software quality and timelines, leading to -
- Poor requirements understanding: Sporadic and ineffective communication can lead to a weak foundation. It results in a poor understanding of requirements. It also makes it difficult for testers to unearth the risks and challenges facing the project.
- Conflicting priorities: Testers who don’t communicate regularly tend to work on conflicting priorities. This causes several hurdles in testing while causing the overall testing project to derail.
- Poor conflict management: Communication is essential testing technique in software testing as it helps convey ideas, manage projects, formulate strategies, or offer feedback. Lack of communication makes it difficult for everyone to be on the same page. It leads to poor visibility into project progress and eventually poor conflict management.
Solution: Encourage frequent communication
Communication is key to the success of any testing team. Frequent and effective communication helps different members stay updated with the latest changes. It helps in improving visibility into the test project. It also helps build trust and understanding between stakeholders and ensures the testing process runs smoothly.
5. Not Testing Enough
Software products, no matter how big or complex, need thorough and comprehensive testing. Not testing them enough can cause bugs and defects to creep into the product. This results in issues such as -
- User dissatisfaction: Inadequate testing of new and updated features can lead to poor user experience and satisfaction. It may cause them to become confused and frustrated if features do not work as expected due to insufficient testing.
- Poor performance: In today’s era of scalable and web-based systems, it is important to optimize software for good performance. Insufficient testing can lead to long page load times, poor image rendering, and delayed server response times.
- Increased maintenance costs: When new changes or additions are not tested enough, it can lead to increased maintenance costs. Teams are forced to spend more time and money fixing issues that could have been avoided.
Solution: Invest in codeless tools
Testing products thoroughly is critical to their success. If detailed testing delays time-to-market, you can invest in codeless tools to accelerate their testing project. Low-code test automation tools enable testers to develop test logic - without worrying about programming syntax. They support modularity and reusability and streamline test case management.
6. Insufficient or No Documentation
Documentation is a crucial aspect of the testing technique in software testing. However, many teams end up ignoring this step, causing several issues at the end of the day.
- Poor test analysis: Test documents, when not prepared properly can lead to a poor analysis of the testing process. This can limit testers’ understanding of challenges and opportunities.
- Delayed feedback: Poor documentation also leads to late feedback, impacting overall testing quality. Such delays make it difficult to avoid doing any mistake in software testing.
- Diluted internal coordination: Skipping on test documentation can also dilute internal coordination. Limited knowledge sharing via different test documents restricts visibility and impacts the quality of the end product.
Solution: Ensure documentation from the start
To enable accurate and high-quality documentation, you must engage in the practice from the start of the test project. Follow a standard structure and format and encourage all team members to review and update the document as the project progresses.
7. Ignoring Test Metrics
In the race to bring products to the market quickly, testing teams neglect software testing metrics. This can have a substantial impact on software quality.
- Poor decision-making: Software testing metrics help measure and monitor test activities. Neglecting them can lead to poor insights into various testing activities, team productivity, and the system’s quality under test. In the long run, it can lead to poor testing decisions.
- Limited insight into challenges: Ignoring test metrics can also lead to limited insight into challenges. Since teams have no knowledge of critical bottlenecks, they have no way to identify or eliminate inefficient tasks.
- Poor testing strategies: Not acting on test metrics also causes teams to rely on the same tools and processes. They fail to make necessary changes to testing strategies and tools and improve the testing process.
Solution: Clearly define test metrics
Test metrics offer the ability to measure testing quality. To calculate effective test metrics, you must clearly identify the processes to measure those. You should also define benchmarks, calculate actual values, and identify areas of improvement.
8. Late Testing
In theory, testing teams are well aware of the importance of testing software early in the lifecycle. Yet, when it comes to real-world scenarios, testing is still conducted after the software has been developed. Such late testing can lead to devastating consequences for testing organizations:
- Costly resolution: When testing is done later in the development lifecycle, bugs are harder to catch and resolve. This leads to costly identification and resolution, impacting the overall quality of the product under test.
- Delayed deployment: Late testing tends to affect time-to-market deadlines. Because developers receive feedback late, it takes more time for them to tweak the underlying code. This causes delays in the development, re-testing, and deployment of software.
- Unstable releases: Late testing also impacts the stability and reliability of the software. Frequent changes to the code base cause it to be volatile and affect the overall quality of the product or app under test.
Solution: Embrace shift left testing
Inculcating a shift-left testing culture can play a big role in improving test results. By testing early and often, you can resolve bugs before they become major problems. Such an approach can also improve code quality and reduce defect rectification costs.
9. Using Too Many Tools
Another common mistake in software testing that software testers make is using too many tools. Agreed, testers must do everything in their power to identify bugs and improve software quality. But this does not necessarily mean using an array of different tools for testing different aspects. The reliance on many tools can lead to several unnecessary repercussions:
- Cost overruns: Investing in too many testing tools costs a lot of money, which adds up to the overall cost of testing. These tools also need regular updating and maintenance, which ultimately impacts tester productivity.
- Additional training: The presence of different tools means testers have to be trained on each of the tools to drive the best results. Lack of training can lead to inefficient usage of these tools which eventually affects test accuracy and efficiency.
- Scattered data: When testers use too many tools, critical test data gets scattered. Lack of integration between these tools causes testers to spend additional time importing data and making the right testing decisions.
- Testing inconsistencies: Using different tools can lead to several inconsistencies in testing. While some features might get tested repeatedly, others might be left out completely. This can cause some bugs to go undetected.
Solution: Implement a unified platform
Adopting a unified test automation platform is critical to software testing success. A unified solution can provide detailed and end-to-end visibility into the entire testing lifecycle. A single platform for web, API, mobile, and desktop testing can also enhance collaboration, boost productivity, and accelerate testing outcomes.
