Hector Castillo CTO at Floe, Inc.

Startups Software Development Review from Hector Castillo
We engaged with aTeam with the goals of designing and building a web app for out customers to monitor and control their IoT devices as well as an admin panel for our team to manage users and devices. I was most impressed by the fact that aTeam did some initial work and wireframing during initial discussions which gave us confidence that aTeam has a solid understanding of our goals and vision before hiring them.I think the main area of improvement is how QA and testing was done and the impact on our timeline. aTeam was good about delivering milestone deliverables on schedule, but there were often issues that would arise in our own testing that were not caught earlier in their testing, which would create additional work. I think impacts to our timeline could have been minimized if their testing had been more thorough and tailored to the user experience, and if expectations were made clearer at the beginning that, after the final milestone was delivered, there would still be an additional debugging period. Otherwise, aTeam was very good about sticking with issues until resolved. Overall, I would be very happy and willing to work with aTeam again in the future and to refer them to others.
Anonymous Director at Assured Accounting

Mobile App Development Review from Anonymous
It’s been pretty cool using this app for handling all our company’s accounting stuff. You just snap pics or upload your receipts and docs right from your phone, which saves a ton of hassle. On the other side, the accounting team can grab everything they need from the web dashboard, so no more chasing papers or emails back and forth. It’s made tax time way less stressful, especially since it’s tailored for the UAE rules and all that. Plus, the folks behind it don’t just drop the app and disappear, they actually keep checking in, throwing out ideas, and sometimes pushing us to think differently. Communication’s been smooth, and they’re not just doing what you ask but really getting into the project. Definitely a game-changer for us.

Web Development Review from Anonymous
We needed a fresh website that actually worked for us, something that could pull in new folks and keep our regulars in the loop without feeling like a hassle. These guys nailed it. The site looks great and runs super smooth, which honestly makes a big difference. Plus, they helped set up a way to grab emails from visitors, so we’re actually turning clicks into real leads now. They’re pretty chill to work with, always open to ideas and explaining stuff without the techy mumbo jumbo. Definitely made the whole process way less stressful than I expected.

Frequently Asked Questions About Software Testing Companies
What services do software testing firms provide?
Software testing companies provide different testing services to identify errors, security risks, performance issues, and how the software behaves in real-life situations and across devices. As part of their software testing service, they also check if each feature works as expected, fix bugs, make improvements, and make sure new software development updates don’t break existing functions, so the software quality remains stable.Â
Hourly rates for QA testing range from $25 to $200+. The final cost is determined based on the size of the software or application, its complexity, required testing type, tech stack (custom-built and older legacy systems cost more), and niche. Â
The rate will also depend on the seniority of the software tester. Across the United States, junior quality assurance (QA) tester may charge $70 to $110 per hour, while the rate for a senior QA mentor and automation engineer can range from $130 to $200 per hour. Â
Special software testing services such as QA audit goes from $5,000 to $25,000.Â
How can businesses know what type of software testing do they need?
Businesses can determine what type of testing solutions they need based on the potential impact of failures and the likelihood of defects. Namely, if they encounter:Â Â
Core functionality issues: Use functional testing to verify features work as expectedÂ
Unstable code or new features: Use unit testing for individual components and integration testing for modules working togetherÂ
Poor system stability after updates: Seek regression testing to make sure new changes didn't break existing featuresÂ
Performance and load issues: Use performance and load testing to evaluate speed and scalabilityÂ
Security issues: Security and penetration testing are commonly used across apps handling sensitive user dataÂ
Hard-to-navigate user experience (UX): Pursue usability testing to determine how intuitive the application is for end usersÂ
Low compatibility across devices: Compatibility testing can evaluate how good the app works on different browsers, devices, and OS versionsÂ
There is also the option to choose between manual and automated testing. Â
Is automated testing more expensive than manual testing?
As an investment, automated testing is pricier than manual testing but offers a lower cost-per-test over time as it can run the same scripts repeatedly, without human intervention. Conversely, manual testing entails lower upfront fee, but its cost grows linearly as the project grows, as every test cycle requires paid hours from QA testers. Â
So, for short-term projects or ones with shifting requirements, manual testing is considered a more economical option, whereas for maintenance and regression cycles, automated testing grants better return on investment.Â
The main distinction between these methodologies is that manual testing relies on human observation and interaction to identify defects, whereas automated testing uses software scripts to compare outcomes against predicted results. Â
Manual testing is best suited for exploratory testing, usability assessments, ad-hoc bug hunting, and minor hotfix verifications where script development would be inefficient. Automated testing, on the other hand, is primarily used for regression testing to make sure the new code does not break existing features.Â
How do businesses measure the effectiveness of software testing?
The effectiveness of the software testing is measured via:Â
Code coverage: The percentage of the code that has been testedÂ
Defect density: The number of defects found per unit of codeÂ
Test case effectiveness: The percentage of test cases that identify defects; helps prune redundant and ineffective testsÂ
Time to detect and fix defects: The time it takes to identify and fix software defects and software bugsÂ
Defect leakage: The number of bugs that "escaped" to production versus those caught during the testing phase Â
