      Software Development Review from Michael S.

      We selected Azumo to develop our software. We transitioned from another development company, so Azumo was initially responsible for migrating our existing code and environments. We are currently still working with Azumo as our nearshore software development team on adding new items to our software.

      shamdani's Review Sourced from Google

      This company hired me back in 2008. I'm Canadian so they applied for a visa for me which had a two month timeline. I got my visa in that time frame and relocated to New Jersey for the job (from Windsor, Ontario). Upon arrival, they told me my position had been taken and that I would need to apply for a senior level role - mind you I was a new grad. They cost me months of time which is stressful as a new grad.

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: 

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
