Understanding Negative Testing in Software Quality Assurance

Software development thrives on creating robust systems. But how do you ensure your creation can withstand not just ideal conditions, but also unexpected user behavior and invalid inputs? This is where negative testing comes in. Often referred to as error path testing or failure testing, negative testing is a crucial aspect of the software development lifecycle (SDLC) that focuses on intentionally providing invalid inputs and exploring scenarios where the system might fail. What is Negative Testing? Negative testing is one of two main software testing strategies (Positive and Negative). Unlike its adversary, Negative testing focuses on test cases that drift away from common use(I.e., providing improper data as input) While positive testing follows an application’s intended steps to make sure it runs as intended. Take for example an application that has a conditional insert field, what will happen if the user enters a space or a character inside an input field for numbers? Negative testing looks for ways that can challenge the application and get it outside its comfort zone to make sure it holds its ground. Some bad results might include system crashes or null outputs of no use. While performing quality tests, we must include all possible events. Our testing engineers look for the most sophisticated way of improper use to make sure the system is aquept for everything. Why is Negative Testing Important? Imagine a website login form that crashes when someone enters a special character in the username field. This might seem like a rare occurrence, but negative testing helps identify and address such vulnerabilities. Here's why negative testing is essential: Improved Stability: By proactively testing how the system reacts to unexpected inputs, negative testing helps prevent crashes and unexpected behavior in real-world scenarios. This leads to a more stable and reliable system. Enhanced User Experience: Users can be unpredictable. Negative testing helps identify scenarios where user errors or invalid inputs might lead to a frustrating experience. By anticipating these situations and implementing proper error handling, you can ensure a smoother user experience. Increased Security: Malicious actors often exploit unexpected system behavior. Negative testing can help uncover security vulnerabilities that could be targeted by hackers. By identifying and addressing these weaknesses, you can make your system more secure. Better Quality Assurance: Negative testing complements positive testing, which focuses on validating expected functionality. Together, they provide a more comprehensive picture of the system's behavior, leading to a higher quality product. How Does Negative Testing Work? Negative testing involves a systematic approach to identifying and testing invalid inputs, boundary conditions, and error scenarios. Here's a breakdown of the process: Identifying Test Cases: This is where testers put on their creative thinking caps. They need to consider various scenarios where users might provide invalid data, exceed expected limits, or perform unexpected actions. For example, a test case might involve entering letters in a numeric field, leaving required fields blank, or submitting unreasonably large data. Executing Test Cases: The identified test cases are then executed by providing the system with invalid inputs and observing the behavior. This might involve manually entering data or using automated testing tools. Evaluating Results: The system's behavior under negative testing is then evaluated. Ideally, the system should gracefully handle invalid inputs by displaying appropriate error messages or preventing the action from being completed. In some cases, the system might be expected to log the error for further investigation. Examples of Negative Testing: Here are some real-world examples of negative testing in action: E-commerce Website: A tester might try entering negative quantities for an item in the shopping cart or use nonsensical characters in the billing address. The system should prevent the purchase from being completed and display appropriate error messages. Login Form: Negative testing might involve entering an excessively long username or password, leaving both fields blank, or using special characters that are not allowed. The system should handle these scenarios gracefully by displaying clear error messages. Mobile App: Testers might try swiping in unexpected directions on the app screen, entering invalid characters in search fields, or attempting to use the app with a weak internet connection. The app should handle these scenarios without crashing and provide appropriate feedback to the user. Best Practices for Negative Testing To get the most out of negative testing, consider these best practices: Think Like a User (and a Hacker): Put yourself in the mindset of a user who might make mistakes or a malicious actor trying to exploit vulnerabilities. This will help you identify a wider range of negative test cases. Start Simple, Then Go Extreme: Begin with basic invalid inputs and gradually move towards more extreme scenarios like entering massive amounts of data or using special characters. Document Everything: Keep a record of the test cases you execute, the results you observe, and any bugs you discover. This documentation becomes valuable for tracking progress and improving future testing efforts. Combine with Positive Testing: Negative testing is most effective when used in conjunction with positive testing. This comprehensive approach ensures that the system not only functions as expected but can also handle unexpected situations. Conclusion Negative testing is an invaluable tool for building robust and user-friendly software. By proactively identifying and addressing potential failures, you can create a system that is more stable, secure, and provides a positive experience for your users. So, the next time you're developing software, don't be afraid to break things – through negative testing, of course! By embracing the unexpected, you can build a system that is truly prepared for anything. Request a Service ...

What is Exploratory Testing

Software testing consists of numerous practices and approaches that help secure overall accurate results through all stages of the testing phase. Most of these approaches are implemented by following certain steps based on pre-planned test cases and assessing the actual results against what is expected. These widely used scripted methods of testing have shown success in including as many scenarios as possible and fully scanning service channels from all angles of usability. But another method relied on heavily and remains valid today follows a more personalized means that would not necessarily abide by scripts. This testing method used to be known widely as Ad-hoc testing. But now it has come to be known most as “Exploratory Testing.” In this article, we will look to define this creative software testing approach and highlight its present importance. We will also look at how exploratory testing works and when to use it. What is Exploratory Testing? Exploratory testing is an approach in which the testing process concatenates both test design and test execution to strengthen simultaneous learning and creative thinking. The difference between scripted testing and exploratory testing is that while scripted testing relies on test designs and requires little to no thinking process, exploratory testing - hence its name – requires exploring and investigating. One major distinction is that this testing is free of automation alternatives, unlike other methods that can substitute human labor with AI-powered systems and tools to implement specific steps that are decided and agreed upon based on design. Why is Exploratory Testing Important? Commonly used methods rely heavily on a documentation process that helps implement a structured manner of testing. These documents and specifications may not always be available, and testing experts would have to rely on logic-based investigations to track bugs firsthand through direct usage, therefore relying on an exploratory testing approach. One other factor that makes this testing important is that it naturally detects more bugs because it involves personalized actions that emphasize a better understanding of the system being used. This testing approach is set out through a journey of realistic usage as expected by users and encourages intuition. Another value to exploratory testing is highlighted by increasing creativity and generating innovative ideas as the work progresses. Alongside other tactical methods, exploratory testing can be mixed with the overall testing project to guarantee excellent results, which serve in the end to increase productivity and quality altogether. How to Execute Exploratory Tests? Here is a detailed description of the steps in which exploratory testing can be executed: A) Creating Bug Classification This step involves three main actions. One is to identify the most common types of bugs based on previous projects, the second is to analyze the causes and the third is to define the risks and produce ideas. B) Creating a Test Charter Test charters include what to test and how to test it - By doing so we have established the starting point of the testing journey based on how the end-user is expected to use the application. C) Review Results Evaluate your results and take notes for future tests. D) Debrief Here we compare what the output is with the test charter and assess whether further tests are needed. In Conclusion Exploratory testing is a distinct approach that is used for multiple purposes that either seem logical and intrinsic or when we want to go that extra mile to ensure better results to serve our users. Therefore, we believe that it will always remain valid for a long time. We at Q-Pros value exploratory testing skills and make sure to prepare ourselves with a team of skillful testers who can rely on diverse and creative testing methods to ensure quality and fulfill requirements.

Though exploratory testing comes with so many benefits, it is bound to have some negative points to it. Here are some of the disadvantages and challenges of Exploratory testing: Exploratory methods strictly depend on skillful testers. Testers would have to be thoroughly knowledgeable about the application being tested. Reporting the outputs of executed tests can be a challenge when there is a documented basis to begin with. It is not suitable for long execution periods. When to use Exploratory testing? When the project demands early rehearsals or when a new tester has joined a project that is already in full action. It can also come in handy when dealing with critical applications (An application that demands continuous usage, and in the unfortunate case of crashing or downtime would result in severe consequences). ...

Regression Testing

To fully utilize software potential in today's market, you need a solid strategy to make it compatible with change. A satisfactory level of adaptability requires constant development on every level of an application structure. This activity will involve tweaking the internal code of the software to enhance its function, a task that will give birth to new bugs and defects, some of which may erupt in different sections than the ones required for the update. This is where Regression Testing is an absolute must for ensuring quality. In this article, we will look at different approaches to conducting Regression testing, and how we at Q-Pros have established a top-notch methodology to ensure our client's applications are fully adaptable to change. What is “Regression Testing”? Regression testing is a type of software testing conducted to verify that an application remains working with the desired level of quality after any code changes or updates/optimizations. It involves a full examination of the application's functionality in addition to making sure that the newly added features are working per demand and no other bugs are introduced due to updates. The Importance of Regression Testing: Enhancing your software application to be on top of new functional standards and adopt new security measures is essential. This regularly guarantees your software success in today’s technological environment. At any stage of development, modifications are bound to cause defects within the application in all sections. This testing technique will help developers identify and verify the impact caused by modification. Types of Regression Testing: Complete Regression Testing As modifications are implanted to a software's code, a complete Regression test is conducted to include all assets of an application to be tested completely from all aspects. This method relies heavily on automated testing techniques because it involves a time-consuming cycle, meaning that every time a change occurs to the code, we must test all other levels including the one being changed. Partial Regression Testing It is where we test the parts most likely to be affected by the change, but it could also involve testing parts that are emphasized by business demand and commonality. It is most efficient when the developing team has verified meta-data and valid information from earlier tests. It might not be the most effective, because it could overlook some areas within the software that might have not been detected properly, or when test scenarios are not being documented and archived by the testing team. Challenges of Regression Testing Regression Testing is essential for companies looking to keep track of constant updates. It could elevate an application's use and guarantee that the software is of the desired quality in all stages of re-development. Having a solid methodology to conduct this testing means knowing and adapting to the challenges one might face while testing. Here are some of the challenges: Regression Testing could be expensive: Testing regularly and constantly could be costly, especially when testing things that have already been tested many times during the pre-production stages. Complete Regression testing is time-consuming: Using complete Regression testing techniques could be exhausting for testers. Going back and implementing a full testing suite every time a modification occurs will be time-consuming for sure. As with most testing approaches, It comes with some setbacks and blockers. Our role at Q-Pros is to overcome those negative points and guarantee that we utilize all testing approaches needed for an application to meet quality standards and achieve client satisfaction.

Parallel Testing

In the Quality Assurance field, there is always the need to look for more innovative ways to perform tests and include more aspects to be tested. We at Q-Pros adopt an approach that relies on innovation rather than labor to create better results and ensure time/cost efficiency. In this article, we learn about parallel testing; What are the main components, advantages, and challenges of Parallel Testing. What is Parallel Testing? Parallel testing is the process of simultaneously testing multiple applications or multiple application components to reduce the execution time of the test factor at hand. Parallel testing involves executing multiple test sequences at once rather than testing for one element separately. To perform parallel testing, we rely on automated testing tools which come in handy when dealing with large-scale testing processes. How to Parallel Test? Parallel testing works best using Cloud-Based Solutions. Certain automated tools are used to run an application feature on multiple devices across different platforms, hence the name parallel. Parallel Testing works by applying and generating possible Browser/Device/Operating-System combinations. By doing so, it asserts inclusivity in tests creating foolproof results. There are many Cloud-Based testing tools to use to activate your parallel tests, tools such as Rapise, Nmap, Nessus, AppPerfect, and QAwerk are utilized in various aspects based on the test at hand. Cloud-based testing in general is time-efficient. Any testing expert should rely on automated tools that function on a cloud to allow for correlation. By testing on a cloud, the testing experts reduce the number of manual tests and get more access to various hardware options. Tests you can perform in a cloud environment include: Functional testing: Functional testing ensures that a software application performs its required features and that it complies with its business requirements. Non-functional testing: Non-functional aspects include performance, usability, and reliability. Non-functional tests could also measure security based on business demands. Ability testing: The goal of any testing procedure is to ensure that an application is compliant and operates within the scope of the desired quality level. Ability testing stretches out to include software features such as defect recovery. Benefits of Parallel Testing: Time-efficiency: Parallel testing speeds up the execution time by executing multiple tests simultaneously. Test coverage: Parallel testing allows you to test on several mobile device desktop/browser combinations at once, covering more test case scenarios and adding confidence to the testing process. Fixing in sprints: Parallel testing allows you to fix bugs and defects during the sprint rather than at the end. Better Dev-Ops: Having to slow down the Dev-Ops cycle by constantly testing and experimenting and producing test scenarios, Parallel testing accelerated the testing process and empowered the Dev-Ops structure. Challenges of Parallel Testing: Unlike other testing approaches, parallel testing requires a larger scale of planning. Due to its nature, this form of testing demands a level of IT knowledge and IT investment. Taking the level of scalability it carries into consideration, DIY parallel testing is almost impossible to accomplish without the help of tech experts. Conclusion What is parallel testing, you ask? Imagine running multiple tests simultaneously across various platforms, browsers, and devices. It's like having a team of testers working in sync, ensuring your product is robust and flawless. Why does it matter? Well, for starters, it's all about efficiency. Parallel testing slashes testing time, allowing you to iterate faster and deploy updates with confidence. Say goodbye to lengthy testing cycles and hello to accelerated development timelines. But it's not just about speed. Parallel testing also enhances test coverage, catching bugs and compatibility issues across different environments. Whether it's a browser glitch or a device-specific quirk, parallel testing ensures a seamless user experience across the board. And let's not forget about SEO.

An Introduction to Agile Testing Methodology

With software testing shifting left (i.e., testing is becoming more present in the initial stages of development) the need for an organized project management strategy to keep up with multiple operational factors in the software development life cycle (SDLC) are more immanent than ever. Relying on Agile methodologies, the testing teams can operate on more levels and secure a bug-free/defect-free product that is constantly tested in all integration stages. For that reason, Q-Pros has adopted Agile practices and consolidated them with our testing process, assuring a swift and efficient outcome for our clients. In this article, we will define the Agile testing approach and connect the dots between Agile and modern software testing and software development. What is Agile Testing? Unlike its predecessor (the Waterfall method), which had a more linear approach, Agile focuses on reiteration and feedback. Agile methods would emphasize flexibility and cooperation between more than one stakeholder in the entire SDLC. A key feature that distinguishes Agile methods is that it relies heavily on continuity and constant testing, gathering information and feedback, and providing it to developers. Agile would increase the quality of the product and ensure improvements, clearing the way and allowing for more integration testing to take place within the process. The main principle in Agile is breaking any project into phases and sprints. It involves constant collaboration with stakeholders. So instead of waiting for one project to end to start with the other, teams cycle through a process of planning, executing, and evaluating. Benefits of using Agile Methods Here are some of the main benefits of using Agile methodology: Develop better quality products Strengthen the relationship between end-users and product owners by constantly collecting feedback Track bugs quickly Saving time and cost and decreasing the risk of releasing crashing products Gaining more flexibility and allowing for more creativity and improvements How Agile Mythology Works in Testing After defining Agile and its benefits, now we will investigate the ways to do it - Firstly, the Agile method can only be achieved through early planning. We start by gathering information from stakeholders and planning the scope of the project. Next would be establishing a testing plan that ensures Quality and aligns itself with the requirements. The testing plan would include milestones, where involving stakeholders would meet in weekly meetings to discuss the ongoing progress of the project at hand. Agile methods embrace mistakes and lesson learning. One distinct value of Agile is that allows the teams to circle back and improve based on previous trials. One way we can fully achieve an Agile-based workflow would be to rely on modern project management software. Tools such as Jira, Azure, ClickUp, and many others are used to assert Agile principles in projects. Agile Testing & Q-Pros Agile testing goes hand in hand with QA, it is now becoming an inseparable approach to setting new guidelines for projects.
