Software Development Review from Daria Stolyar
We hired Altoros engineers as an essential extension of our client-facing internal teams. This was a tough decision because our reputation as a brand depends on the overall efficiency of our processes and we needed to make sure all risks are mitigated when it comes to delivery. Altoros has not let us down.Together with Altorosians we successfully deployed a number of tough and technologically complex projects on time. So our collaboration is certainly set to continue.

Software Development Review from Victoria Lewis
We enjoy working with our team, Roman Yurkin, Tatyana Kobzar, Svetlana Kalchanka and Tatiana Anop. They bring expertise and immense value to our business with each piece of work they complete. They are a major part of our business development and delivery.

Ruby on Rails Review from Greg Lipper
In my 30 years in the software business, I have never had as positive an experience with an outsourced development services provider as I have with Altoros. Each Altoros engineer we have worked with has been strong technically, estimated development times accurately, completed projects on time, and delivered code and projects with high quality. Beyond that, they have helped improve our thinking and approach with suggestions and ideas that were better than the spec of instructions we supplied.

Caring Gene's Review Sourced from Google
Troy Web took over the maintenance and service contract for our in depth healthcare career information and job posting website. Their ability to seamlessly take ownership, clean up and bring our site into a stable wordpress environment was done not only quickly, but also flawlessly. During our time with Troy Web, a number of updates and additional features were required to be built. They were not only able to build these aspects, but also to correct past build issues in the process making the site more reliable on a daily basis. In the last 6 months of their service we didn’t experience any unforeseen downtime with our website, which is extremely important to the function of our site for those that access and use it on a daily basis. Troy Web provides an exceptional service with a team that is always available and very knowledgeable.

Espresso Moon Reviews & Testimonials
Bradley Collins's Review Sourced from Google
Working with the guys at Espresso Moon (Scott, Doug, Tim and Dwayne) was truly a great collaboration and experience. They didn't just throw a website together for us, they helped us to reinvent ourselves. They go out of their way to get to know you and your business to the fullest extent, and that is a quality that is not often seen. If I were to recommend a web design/hosting company to anyone, Espresso Moon would be the one and only name I give. Thank you for your service and support!
Meredyth Jones's Review Sourced from Google
I worked primarily with Scott, Tim and Doug to build a fairly complicated site: Paypal/credit card payments, video training modules, a graded quiz, and issuance of a completion certificate. They were the only website company that invited me to an in-person meeting and that was tremendously helpful in me understanding how they work and them understanding my goals. Large Animal Consulting & Education launched 2 days ago and the site is running smoothly. I'm very happy with the site they designed (they also designed my logos) and am looking forward to using them to support and add to the site down the road.
Caleb Schallert's Review Sourced from Google
Doug Wheeler is the owner of Espresso Moon and he has provided my small business excellent IT technical support for our website. His team helped me out by removing malicious code that was affecting my site right after the Heart Bleed epidemic last year. He got my site back up and running so i could continue business and save my online reputation. I would recommend Espresso Moon LLC to anyone in need of a new website or mobile application because they follow through with what they promise to do, on time and on budget. They are truly a pleasure to work with!

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.
Core services include:
- Functional testing
- Performance testing
- Security testing
- Usability testing
- Regression testing
- Automation testing
- Accessibility testing
- Mobile app testing
- API testing
- Compatibility testing across devices/browsers
- Compliance testing
- Testing with artificial intelligence (AI) tools
- QA audit
How much do software testing services cost?
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.
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.
Special software testing services such as QA audit goes from $5,000 to $25,000.
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:
- Core functionality issues: Use functional testing to verify features work as expected
- Unstable code or new features: Use unit testing for individual components and integration testing for modules working together
- Poor system stability after updates: Seek regression testing to make sure new changes didn't break existing features
- Performance and load issues: Use performance and load testing to evaluate speed and scalability
- Security issues: Security and penetration testing are commonly used across apps handling sensitive user data
- Hard-to-navigate user experience (UX): Pursue usability testing to determine how intuitive the application is for end users
- Low compatibility across devices: Compatibility testing can evaluate how good the app works on different browsers, devices, and OS versions
There is also the option to choose between manual and automated testing.
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.
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.
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.
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.
How do businesses measure the effectiveness of software testing?
The effectiveness of the software testing is measured via:
- Code coverage: The percentage of the code that has been tested
- Defect density: The number of defects found per unit of code
- Test case effectiveness: The percentage of test cases that identify defects; helps prune redundant and ineffective tests
- Time to detect and fix defects: The time it takes to identify and fix software defects and software bugs
- Defect leakage: The number of bugs that "escaped" to production versus those caught during the testing phase
