How accessible are online voter registration websites in U.S.?

Konstantin Klyagin — Fri, 29 Nov 2024 11:01:48 +0000

Nowadays in the digital age, ensuring that all citizens have equal access to essential services like online voter registration is paramount. Online hurdles are present in all U.S. voter registration systems, according to a recent report by QAwerk, a software testing business that specializes in web accessibility testing services. The audit found considerable differences in performance between jurisdictions, raising questions about whether these essential services are accessible to all.

The main conclusions of this thorough study are included in this article along with information on typical accessibility issues, states that excel at offering accessible registration alternatives, and regions that urgently require improvement.

Democracy depends on voting, yet many eligible voters struggle to register online due to inaccessible websites.

Individuals with disabilities, those with limited access to technology, and those who may have poor levels of digital literacy are disproportionately affected by these hurdles. According to the Web Content Accessibility Guidelines (WCAG), websites must be designed to be perceivable, operable, understandable, and robust for all users.

These fundamental requirements have sadly not been met by many US states, which makes it challenging for underrepresented groups to successfully exercise their right to vote. QAwerk conducted thorough accessibility testing on various state online voter registration platforms, revealing widespread issues that require urgent attention before the next election cycle.

Key Accessibility Issues Found

During the audit, several common problems were identified that hinder the user experience for individuals with disabilities:

Keyboard Navigation Problems: People who use keyboards instead of mice may find it difficult or impossible to use many voter registration websites since they still need keyboard-only navigation. This poses a significant obstacle for users with mobility problems who cannot finish the registration procedure using a mouse.

Screen Reader Compatibility: The screen reader compatibility test was only passed by 6 out of 43 websites, or 14% of the total. Blind or visually impaired users find it challenging to access information or finish registration on their own when screen reader help is lacking. The fact that 37 websites failed to meet this criterion emphasizes how serious the issue is.

Poor Color Contrast: Poor contrast between text and background colors was present on almost 53% of the websites (23 out of 43), making it difficult for people with impaired vision to read the material. Insufficient color contrast can make important information hard to read, which could deter consumers from finishing the registration process.

Inaccessible Forms: 33 out of 43 websites, or 77% of the total, lacked appropriately designated input areas in their forms. For users who depend on assistive technology, such as screen readers, which depend on precise labeling to direct users through form completion, this presents a serious problem. Errors during registration are more likely when labeling is done incorrectly.

Lack of Captions or Text Alternatives for Multimedia: Websites with multimedia information but no written explanations or subtitles put those with hearing problems at a disadvantage. Users with hearing impairments cannot access important information without appropriate subtitles or alternate text, which makes the registration process even more difficult.

States Leading in Accessibility

Some states are establishing high criteria for accessibility in their voter registration procedures despite the many obstacles.

Notable leaders in this field include North Carolina, which scored 14 out of 15 points in accessibility testing for having an easy-to-use online registration system.

This state provides attributes like:

Clear and Intuitive Navigation: Users can easily navigate through the site and complete forms without confusion or frustration.
Strong Visual Contrast and Text Resizing Options: With the help of these tools, people who are visually impaired may easily access all material and tailor their viewing experience to suit their needs.
Comprehensive Screen Reader Support: North Carolina's websites are completely accessible with assistive technology, allowing blind and VI users to swiftly and freely navigate and finish their registration.

Best Practices for Improving Accessibility

Consider the following recommended practices to improve accessibility and develop inclusive voter registration websites:

Conduct Regular Accessibility Audits: States should periodically evaluate their websites using tools like those offered by QAwerk to identify and rectify any accessibility issues.
Follow WCAG 2.1 Guidelines: Websites will be made accessible to people with a variety of disabilities if these agreed standards are followed.
Test with Real Users: To comprehend real-world issues and make sure that voter registration platforms are user-friendly, it is essential to involve people with disabilities in evaluating their performance.
Provide Multiple Language Options and Simplified Text: To ensure that people with cognitive impairments or inadequate English proficiency can understand the registration procedure, materials in several languages and simplified text are provided.

Conclusion

As elections approach, it is critical to improve the usability of online voter registration systems. States must take immediate action to eliminate barriers and ensure that everyone participates in the democratic process. To comprehend the present condition of these platforms and pinpoint areas in need of development, ongoing investigation and testing are crucial.

By putting accessibility first, we can foster a more welcoming atmosphere where everyone can express their opinions. By working together, we can create a democracy that really benefits all citizens and opens the door to a more promising and just future.

How to measure software developer productivity

Konstantin Klyagin — Fri, 23 Aug 2024 13:25:17 +0000

Focusing on incorrect developer performance metrics can cause critical issues. Look at fundamental metrics to improve working processes and keep a positive environment.

We often see how developer productivity directly affects a company's success or, sometimes, failure. If developers use time efficiently, the team can keep up with the competitors, which causes delays in providing the features users wait for.

When workforce reduction is necessary, tech leaders should decide who stays and who leaves. They must be cautious not to mistakenly let go of high performers that drive company growth and make cuts based only on seniority or experience. Mistakes here are critical for a company's well-being or existence, so making data-based and unbiased decisions is mandatory.

But how do you evaluate something so abstract, complex, and creative as software development? Let's take a look.

What's wrong with measuring productivity

Whether you choose DORA, SPACE, McKinsey's, or another framework, remember it might not be a good fit for your team, especially because many developers either need to learn about them or think they don't work.

One more challenge here lies in the collaborative nature of the software development process, which is hard to track. It's far too easy to fall into the trap of wrong practical use, for example, by applying DORA to measure an individual's performance.

Finally, once you announce a new productivity metric, your brilliant team can try to artificially high their scores to prove their proficiency. Don't blame them; you'd likely do the same if you were in their shoes, and let's think how to deal with this.

Stop Tracking Vanity Metrics

First of all, here are a few examples of vanity metrics that may seem convincing, but their results don't reflect the accurate picture and miss the fundamental goal of measurement:

Hours worked. Yes, it's easy to track, but we know that long hours don't directly correlate with productivity.

Lines of code. Lengthy code can highlight poor quality, and measuring this leads engineers to adopt bad practices to meet their KPIs.

Bugs fixed. Bugs have different levels of complexity and importance, and this quantity metric likely gives your team the illusion of hard work.

Deployment frequency. While valuable for assessing teams or systems, deployment frequency relies on everyone doing their responsibilities and is not a reliable metric of individual productivity.

Focus on metrics that matter

Just say no to overthinking. Instead of reinventing the wheel, choose a few metrics and try how they fit your development team. Gather information from last one-to-one meetings, peer reviews, and self-assessment surveys as a starting point. At Redwerk and QAwerk, we collect this kind of qualitative data every 3 months. We've been doing it for the past 19 years. You'll have enough data to clarify how well the software engineer manages their tasks, how involved and proactive they are, and what skills they need to improve.

Sticking to Deadlines
Developers should estimate how long features will take before starting tasks to set realistic expectations. Regularly missing deadlines leads to bottlenecks, chaos, and long-term team burnout. Reviewing historical data and conducting a thorough investigation can help managers determine whether inaccurate estimates or the developer's speed is the issue. However, sometimes the problem with estimation extends beyond a single engineer's role and requires more attention from tech leaders.

Code quality
Code quality seriously influences product metrics and, as a result, business success metrics too. Poorly written code is hard to reuse and will need costly refactoring. Likewise, new teammates may spend hours deciphering it, which delays feature development. To avoid this, teams conduct regular peer reviews or involve experts in complicated code audits.

Monitoring the bug rate (number of bugs detected during testing) is a different way to know code quality issues. This metric, usually a ratio or percentage of bugs per unit, like lines of code, indicates possible codebase issues. A high bug rate suggests serious defects, while a low rate shows better stability.

Problem-solving skills
With so many AI-powered code assistants available, writing quality code that meets industry standards has become much easier for developers. The seniority of an engineer now means their problem-solving abilities. Do they quickly mark challenges as "impossible" or deep dive into research and develop solutions?

Interpersonal skills
A top performer consistently delivers not only quality code but also works seamlessly with teammates. They proactively communicate possible threats or blocks, offer improvements to feature implementations with clear reasoning, and are always ready to help their team reach goals.

Final thoughts

Measuring developer productivity has just one reason: it's a long-term success. It's not about comparing one engineer to another based on their metrics. Use this to identify factors that might boost productivity. It should also be a collaborative effort between managers and developers to build an environment where every developer can grow and help drive the company's success.

CrowdStrike security update triggering mass Windows outage

Konstantin Klyagin — Tue, 23 Jul 2024 07:52:54 +0000

The idea that a single IT misstep could cripple companies across entire industries might have seemed like a huge overstatement. However, the recent Microsoft outage is a stark reminder of how interconnected our world is. On July 19th, 2024, a faulty security update from CrowdStrike wreaked havoc on Microsoft Windows systems worldwide. How could such an IT catastrophe unfold? Let’s dive in and explore the causes.

What happened?

Many high-profile companies, such as JP Morgan Chase, Walmart, and Shell, use Falcon, CrowdStrike’s cybersecurity software, to protect their IT infrastructure from data breaches. In fact, it’s used by 82 percent of US state governments and 48 percent of the largest US cities.

Unlike traditional security systems that require bulky hardware and constant updates, CrowdStrike Falcon operates entirely in the cloud. It works through an agent installed on user devices, be it Windows, Mac, or Linux. Once installed, this program connects seamlessly to CrowdStrike’s cloud platform.

So, CrowdStrike’s latest software update for Windows users turned out to be faulty, causing a Blue Screen of Death (BSOD) at boot. You need the system to boot to be able to roll back that update, which is a dead-end scenario for a non-technical user.

Adding to the confusion, an outage hit Microsoft Azure services and the Microsoft 365 suite of apps in the central US earlier on Thursday. While a company spokesperson clarified these as separate issues (one impacting Azure, the other CrowdStrike), cybersecurity consultant Thomas Parenty (a former National Security Agency analyst) offered a different perspective. He suggests a possible link: “The systems required for the connection to Azure could have been initially impacted by the CrowdStrike issue, rendering the service unavailable.”

Talk about a chaotic end to the week!

What are the consequences?

The widespread impact of this incident is staggering, considering the CrowdStrike agent is installed on millions of devices – from servers and personal computers to even internet-connected devices (IoT). The update, intended to enhance system security, ironically caused widespread crashes across various industries, including:

Transportation: Airports around the world faced flight delays and cancellations as critical systems malfunctioned.
Healthcare: Appointment booking systems and patient record access were hindered at hospitals and clinics.
Finance: Banks and other financial institutions experienced technical difficulties.
Media: Television stations, like Sky News, were temporarily knocked off the air.

Why did this happen?

Firstly, most organizations deploy software updates automatically, so the rogue update spread like wildfire. Secondly, the culprit was a poorly written code – an error that CrowdStrike has since taken full responsibility for. While the exact details of this blunder remain unclear, one thing is certain: rigorous software testing could have prevented this IT disaster entirely, or at least significantly reduced its impact.

Why the update might have caused issues:

Insufficient Testing: CrowdStrike’s QA process for the update might not have been thorough enough. Software as critical as Falcon should be tested on dozens of devices and hundreds of different environments.
Testing Environment Limitations: CrowdStrike’s testing environment might not have perfectly replicated real-world conditions. This could lead to issues showing up only when the update interacts with other software on user machines.
Regression Testing Overlooked: It’s possible that regression testing, which ensures new updates don’t break existing functionalities, might not have been conducted properly. This could explain why a security update triggered system crashes.
Human Factor: We are only human, after all. And it’s a universally agreed-upon IT rule not to release anything on Fridays. Perhaps it was a time-sensitive update, and people tend to make the silliest mistakes when pressed for time.

What can Windows users do?

The good news is that CrowdStrike engineers shared a workaround. Here it is:

Boot Windows into Safe Mode or the Windows Recovery Environment

Navigate to the C:\Windows\System32\drivers\CrowdStrike directory

Locate the file matching “C-00000291*.sys”, and delete it

Boot the host normally

The bad news is that it doesn’t work for everyone. First, if you’re not a techie, you don’t understand half of what’s here. Also, this manual fix can’t be applied remotely or to cloud-based systems, requiring physical access to each impacted device. Unfortunately, this translates to a lengthy recovery process for system administrators.

Prevention is better than cure

So, what lessons can we learn from one of the most widespread tech meltdowns? Prevention is always better than cure. While having a detailed incident response plan is good, what’s even better is having an ongoing and well-established quality assurance process.

Prevent Faulty Updates With These Testing Types:

Unit Testing: This involves testing individual components of the update in isolation. This could have identified issues within the update code itself before it interacted with other software.
Functional Testing: This verifies if the update delivers its intended functionality without causing unintended consequences. This could have involved testing the update on various Windows configurations and with different software combinations.
Integration Testing: This focuses on how the update interacts with other software on a system. This could have revealed compatibility issues with specific Windows versions or drivers.
Regression Testing: This ensures the update doesn’t introduce new vulnerabilities or crashes.

Strengthen Your Infrastructure and Processes:

Canary Releases: Deploy new updates to a small subset of users first to identify any critical issues before a full rollout.
Feature Flags: Isolate new features behind feature flags to enable quick rollback if necessary.
Immutable Infrastructure: Use immutable infrastructure to reduce the risk of configuration drift and make rollbacks easier.
Chaos Engineering: Intentionally introduce failures into the system to identify vulnerabilities and improve resilience.
Post-Mortem Analysis: Conduct detailed post-mortem analyses after incidents to identify root causes and implement preventive measures.

Improve Communication and Collaboration:

Incident Response Playbook: Create a detailed incident response playbook that outlines roles, responsibilities, and procedures for handling outages.
Cross-Functional Teams: Foster collaboration between development, QA, operations, and security teams to ensure a holistic approach to software development.
Regular Security Audits: Conduct regular security audits to identify and address vulnerabilities.

Mobile Game Testing: Essential Test Cases to Ship It Smooth

Konstantin Klyagin — Thu, 06 Jun 2024 19:55:23 +0000

The competition in the mobile gaming industry is fierce, and developing a game that will go viral is a challenge in itself. Should you even bother making mobile games in 2024? Well, the market is projected to hit a whopping $99 billion globally in 2024, reaching nearly $119 billion by 2027, with almost 2 billion users.

Another thing that can make it worthy of your investment is prioritizing quality over quantity, a prominent trend in 2024. High user ratings not only prompt others to try out your game but also can influence app store algorithms, giving it more visibility.

Good quality is only possible with thorough testing. But what exactly is meant by “thorough”? Device fragmentation, frequent OS updates, different network conditions, multiplayer features, and localization – all of these require attention. In this post, I’ll share time-proven test cases to help you release well-polished mobile games that users will play on repeat.

Functional Test Cases

Don’t want your users to rage quit? Then do some functional testing to make sure each component of your game operates as it should:

Verify if no issues appear during game installation, launch, shutdown, and uninstallation
Test user registration and login process
Look for UI bugs like misaligned elements, glitches and artifacts, unreadable text, and areas prone to misclicks
Test your gameplay mechanics like controls, physics, AI behavior, combat mechanics
Ensure that difficulty levels are appropriate and there are no exploits
Test everything audio-related: audio settings, sound effects and background music, and audio synchronization
Run the game in different network conditions (Wi-Fi, 3G, 4G, 5G, no network)
In the multiplayer mode, check the matchmaking process and lobby chat functionality
Test in-app purchases, ensuring the purchased items are delivered and correctly reflected in the player’s inventory
Check if users can subscribe to paid services and whether the subscription grants the advertised benefits
Test refund processes and error handling in transactions
Check if the game can handle unexpected errors, such as connectivity issues, device limitations, and internal errors, gracefully

Example of a functional bug in Cross The Ages: TCG. Agreeing to Terms of Service results in an error

Compatibility Test Cases

Compatibility testing may feel like a grind, but that’s what will help you address the device fragmentation challenge. You want to provide a seamless experience for as many players as possible:

Test how the game works on the target operating systems
Keep track of operating system updates and perform regression testing to verify compatibility with new OS versions
Verify that your game supports gestures specific to the OS, like swipe on Android or 3D Touch on iOS
Check whether your game drains the battery when it’s running in the background
Test the game on multiple popular devices with varying screen sizes, resolutions, and aspect ratios
Check your game compatibility with external game controllers, such as MFi controllers
Test the game’s interaction with other installed applications and third-party services

Example of a compatibility bug in Elemental Raiders: On iPhone 12, the search screen is cropped and impossible to scroll

Performance Test Cases

Don’t want to lag behind your competitors? Provide lag-free gaming. Performance testing will help you achieve a visually stunning and responsive game. Here’s what needs to be done:

Check if the install and launch times are adequate
Monitor the frame rate during gameplay, documenting lagging or dropped frames
Test how quickly the game drains the device’s battery
Check if the amount of memory the game uses exceeds device limitations
Monitor the workload on the device’s processor and graphics card and watch for overheating
Perform initial load testing to determine the game’s baseline performance
Identify the point where the game’s performance starts to degrade by gradually increasing the load
Push the game to its limits with high user loads or intense gameplay scenarios to identify its breaking point
Test if your game crashes or loses progress in case of interruptions, such as incoming calls, text messages, alarms, or switching apps
If applicable, verify if the game functions properly offline and transitions seamlessly between online and offline modes

Example of a performance issue in Couple Up!: Most API requests take longer than 3 seconds to respond

Security Test Cases

Hackers taking someone else’s loot can spoil the impression of your game and undermine players’ trust. Level up your game’s security by running these test cases:

Verify that only authenticated users can access the game
Check account lockout mechanisms and password recovery processes
Test if authentication mechanisms like 2FA are strong enough to prevent unauthorized access
Check what permissions the game requests and whether they are justified
Check if the user can revoke granted permissions at any time
Check if the game complies with data privacy regulations like GDPR, COPPA, CCPA, depending on your target audience

Usability Test Cases

Every mobile game developer wants players coming back. Usability testing helps assess how easy it is for players to go from noob to ninja and understand what to tweak to make it more fun and rewarding.

Test the general usability, looking into things like clarity and brevity of instructions, content abundance and variety, and overall impression
Check the ease and consistency of navigation, ensuring the menu structure is clear, and controls are always used in the same way
Test the game balance, ensuring it’s challenging enough to be fun, but at the same time, gives players a fair chance of success
Check if the game provides players with a sense of purpose and direction
Evaluate how satisfying or frustrating the progression level is

Localization Test Cases

Developers who want their games to resonate with a worldwide audience localize them. Some do it better than others, and one of the reasons why is the extent of localization testing they perform. Here are must-know test cases to guarantee an immersive experience regardless of the player’s language:

Check if all in-game text elements, including menus, buttons, tutorials, dialogues, and error messages, are translated into the target languages
Ensure all audio content is translated as well
Verify if translations are contextually appropriate and convey the intended meaning and humor
Document typos, awkward line breaks, and texts overflowing their containers
Check if special characters, accents, and diacritics are displayed correctly and do not cause crashes
Confirm that the font used supports all required characters in the target languages
Watch for cultural references, jokes, or idioms that might not translate well or be offensive in the target culture
Verify that date and time formats, currency, and measurement units (meters, feet, kilometers, miles) are adapted to the target country’s standards

Final Thoughts

The mobile gaming market isn’t just massive; it’s hungry for quality. In 2024, gamers crave polished experiences, and those can be achieved with ongoing professional testing. Checking if the game runs on your friend’s phone won’t cut it. While this list of test cases will equip you with a solid foundation for testing, remember, there’s no one-size-fits-all approach. The key is to craft a mobile game testing strategy unique to your game’s genre, target audience, and market trends.
