I recently had the pleasure of working with Alty to develop our mobile app. We needed a developer who was able to translate my vision and provide technical guidance. The experience has been nothing short of outstanding. From the initial consultation to the final product, Alty's professionalism, expertise, and dedication have exceeded my expectations. Alty has demonstrated a deep understanding of mobile app development and was willing to go the extra mile. Their ability to translate my ideas into a seamless, user-friendly, and visually appealing app is truly impressive

Web Development Review from Linda Josh
I had a few conversations on the Designrush site. I was searching for outside engineers who could be hired for building projects and for outsourcing. I finally spoke with Grey Space Computing after corresponding with a few others. (Gaurav Hire), the Senior Software Engineer, put me at ease right away when we chatted. We discussed everything from their assistance in getting started to their previous actions. Even when they told me that some of my ideas weren't as good as I had anticipated, they did it without hesitation. That candor was much appreciated. I didn't want someone to construct anything for me only to take advantage of me financially. His candor suggested that he was interested in the relationship I was trying to develop. The team built a huge web application. They used WordPress.Infact,Theyre the only ones Ive ever worked with, but I have no regrets working with them. I dont have any thoughts of trying another company. These guys have been spot on all the way. There may have been some Java.

HR Outsourcing Review from Richard Kim
We received guidance on HR related topics which helped out in strengthening our HR policies. The guidance was based on decision-making processes and has reviewed all of our documentation. Grey Space Computing Solutions communicates promptly through virtual meetings. Moreover, we appreciates Grey Space Computing expertise and understanding of their concerns.

UX Strategy Review from Lydia Evans
After compiling user feedback, we wanted to improve our user experience. Grey Space Computing produced a UX roadmap that we might use to enhance our website's functionality. Furthermore, we required our internal team to be able to customize these functionalities in the event that any changes were to be made.Grey Space Computing members were experts that brought our design vision to life. They were able to optimize our UX through their deliverables this was our main success metric for their work, considering that we couldn't have positively changed our website on our own. The innovative ideas provided by Grey Space Computing that made our venture a success truly amazed us. They were aware of our needs and made adjustments to meet them.

As part of the voluntary administration group for the Inspire Foundation, I have worked closely with Julie and the Custom D team in the setting up of the Foundation's online application process. The team have been amazing to work with, finding solutions for the step by step processes as we worked our way through the implementation of the online system. Starting from scratch, their ability to grasp our needs quickly and clearly most certainly went a huge way towards creating a seamless process from what was a daunting prospect in the beginning. The open communication lines and prompt results greatly impressed me and I whole heartedly recommend Custom D as THE company to go to for all of your software, website and database design requirements.

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
