Silent Protection Failures: When Every Test Passes and the User Is Still Exposed

Software Testing Magazine — Mon, 21 Sep 2026 21:39:23 +0000

A privacy product tells a user that her personal data has been removed from data broker sites. Every test in the suite passed. Was the data removed? Most test suites cannot answer that question, and this article explains why, and what to do about it. Author: Yevheniia Sakovets, https://yevheniiasakovets.com/ Consumer privacy and security software makes a specific kind of promise. It does not promise a feature; it promises that something happened. Your data was deleted. Your password is encrypted. Your files were wiped. Your credentials have not appeared in a breach. The user cannot check any of these claims. That is the whole reason she bought the product. I have spent the last year owning quality for exactly this kind of software, and before that thirteen years verifying data as it moved across systems in fintech, e-commerce, medical devices, and a loyalty platform with tens of millions of users. The defect class described here is the one that worries me most, because it does not look like a defect. It looks like success. I call it a silent protection failure: the software reports that a protective operation has completed, and it has not. Why every test passes anyway Think about how a deletion request actually travels. The user enters her name, email, and address in the interface. The interface sends that to an API. The API hands it to a backend service. The backend builds a request to an external party, in this case a data broker, and sends it. [...]

Your AI Doesn’t Know What Is “Correct”

Software Testing Magazine — Mon, 14 Sep 2026 16:50:01 +0000

AI-assisted code generation has changed the capabilities of organizations to produce code. In this article, Hélder Ferreira discusses the impact on software quality created by this new situation. The main problem is that this new code is often created by tools that lack the knowledge of the global context of both the application infrastructure and the process being automated. Using functional tests as a baseline might help to limit the risks. Author: Hélder Ferreira, Director of Product Management, Sembi, https://www.sembi.com/ Everyone knows that AI “speeds” up development. Recent research found that developers using AI tools increased their coding activity, measured by commits, by as much as 180%. But producing more code doesn’t necessarily mean better software: AI-generated code often introduces errors that leave developers picking up the pieces. AI-generated code forces software developers to rework and debug the code that “only took a few seconds” to create. What’s missing and keeping AI from accurately producing and shipping code is a written, testable record of how the product should behave. Much of this context lives in disconnected tools or internal knowledge, leaving AI to guess at a developer’s intent. This is where test artifacts help AI-assisted development. Test context breaks down detailed user flows written in step by step detail. Unlike requirements or other dev artifacts that show a snapshot of how features were once built, tests capture your product’s truest expected behavior and your regression suite aggregates the cumulative and latest expected behavior of your product functionality including the multitude [...]

How to Review Your Traceability Matrix to Strengthen Test Coverage

Software Testing Magazine — Tue, 01 Sep 2026 19:58:10 +0000

A fully green traceability matrix can make it look as though requirements are properly covered. Yet a link between a requirement and a test does not prove that the test actually verifies every required behavior. Requirements coverage gaps can remain when tests are incomplete, when a requirement evolves without its tests following, or when a test changes while its traceability link remains intact. This article proposes a simple way to detect them: first understand how they arise, then structure the review by comparing explicitly required behaviors with what the linked tests actually demonstrate. Author: Benjamin Chollet, KomAInu, https://komainu-ai.com/ Why a Green Matrix Is Not Enough REQUIREMENT The system shall reject inputs longer than 100 characters. LINKED TEST Verify that the input field is displayed and accepts user input. There is nothing inherently wrong with the link: both artifacts concern the same feature. But the test says nothing about the 100-character limit. Traceability tells us that a relationship exists; it does not tell us what the test demonstrates. Here, I use covered to mean that the tests demonstrate the behavior stated in the requirement. That is a stronger claim than saying that one or more tests are attached to it. Figure 1. A traceability link can be valid even when the required behavior is not verified. (click on image to enlarge) How Coverage Gaps Appear Coverage gaps often hide inside tests that are otherwise relevant, useful and passing. Two causes are particularly easy to miss: incomplete verification of the required behavior [...]

This is why you need to perform cross-browser testing for your automated tests. This article lists the main desktop or online cross-browser testing tools available today. Some of these tools are open-source, some are commercial with a free plan. Use our contact form to make us aware of some cross browser testing tools that we should add to this list. Cross-browser testing is a software testing activity that check the quality of web applications across multiple browsers, devices and operating systems. Screen size, screen resolution, OS version, browser versions, JavaScript and CSS languages support are elements that impact how your users are viewing content on a moblie phone, a tablet or a desktop screen. Cross-browser testing helps you to understand and verify these different user experiences for the main devices and system used by your target audience. Here are some questions you should ask yourself when looking for a cross-browser testing tool: Are you testing on real devices vs. emulators/simulators? How many browsers, devices and operating systems are supported by the platform? How can you test: writing your own scripts, with a record & replay tool or supporting an existing software testing framework like Selenium? How much software testing power or which features do you need and get in the pricing plans: number of users, virtual location, testing time, parallel usage, support, external tool integration (bug tracking, continuous [...]

Secrets of Successful Testing for CRM Implementations

Software Testing Magazine — Mon, 10 Jun 2024 13:12:18 +0000

Integrating a CRM tool into your enterprise will change everything. This way, you’ll get far more actual insight into the behavior of your customers when using your platform and interacting with your various systems. The problem with this, however, lies in the fact that your CRM needs to be integrated with each of these tools and a system as a whole. So, before you launch it, you need to check if everything is implemented correctly. You need to test it. To help you out with this, here are a few secrets of successful testing for CRM implementations. Understanding why you’re doing it You need to start by understanding the importance of software testing when implementing CRM. It doesn’t matter if you find the most credible review of CRM apps shortlisted and pick something top-rated from here. Unless you integrate it right, it won’t give you the results you’re looking for. First, you need to make sure you identify all the bugs in the application. Even if you discover a bug, it won’t be the end of the world. As soon as it’s discovered early enough, you can fix it before it causes any real outrage. Other than that, you need to understand the importance of actually working on software improvement. The majority of modern software is actually SaaS, which means that you have a live service, and your audience expects improvement all the time. Fortunately, there are always bugs to fix. By being really vigilant about updates, and if you [...]

The Critical Role of Software Testing When Upgrading Your ERP

Software Testing Magazine — Tue, 09 Apr 2024 15:37:15 +0000

As a decision-maker for your business, you are faced with challenging questions every day. Whatever industry you work in, there are business technologies that you rely on to create an efficient operation and keep your employees on the same page. One of those technologies may be an enterprise resource planning program or ERP. An ERP helps you run your business effectively, improving operational processes like human resources, manufacturing, supply chain management, client services, finances, and more. Businesses with larger operations are more reliant on the features of an ERP because there are so many processes to manage. Upgrading to a newer version of your current ERP, or switching to an ERP for the first time, can be a challenging process. Often, the transition is confusing as your team must learn how to replicate older processes or adapt to a different platform. This is why software testing during the upgrade process is so important to reduce the level of disruption to your operation. Let’s talk about the role that software testing should play when upgrading your ERP tool. Functional Testing First and foremost, you need to verify that the software is going to perform as expected. That means testing to see if the new features work as they are advertised. For example, if you are adopting an ERP for the first time, perhaps one of the primary features you are excited about is automated business processes. Testing the software to see if you can translate some of your current manual tasks [...]

How New Software Solution Is Tested During Legacy System Upgrade

Software Testing Magazine — Wed, 27 Mar 2024 08:37:41 +0000

While revamping aging business systems, rigorously testing new components minimizes disruption risks before deployment. We explore best practices to confirm that stability, seamlessness, and security meet standards throughout the transformation process. The Role of Testing Complex legacy platforms with years of patchwork face unpredictable behaviours when undergoing upgrades. Thorough validation ensures alterations integrate smoothly without introducing defects. Structured testing from ModLogix confirms revamped solutions uphold capabilities across: Functionality – All features work without regression, including edge use cases. Data Integrity – No corruption, losses or miscalculation through changes. Performance – Acceptable response times under peak loads sans degradation. Scalability – Handles increasing users, transactions and information volumes. Resilience – Understands stresses and recovers correctly from failures. Security – No fresh vulnerabilities or gaps allowing unauthorized access. Frequent testing across the transformation timeline prevents realizing issues in late crimping projects and adoption after launch. Key Testing Strategies The United States government spends more than $100 billion annually on information technology. The majority of that will go toward running and maintaining current systems, including older ones known as “legacy” systems. These systems can be expensive to maintain and are open to intrusion by hackers. Companies also spend a lot of money on maintaining outdated software, so in some cases it’s better to update it and test it well. Testing suites combine tactics exposing different flaws: Unit Testing Validates individual code components like functions or API endpoints in isolation to verify correctness before integration. Tests all execution paths, including exceptions to validate robust logic. Integration Testing [...]
