Robosoft Technologies Reviews & Testimonials
Issac John Ex-Business Head, Discovery Plus at Discovery India
5.0★
Wearables Review from Issac John
A global OTT provider - Discovery+ earlier this year, had a breakthrough launch in a cluttered OTT market like India with a differentiated product targeted at lifelong learners and passionate communities. The team at Robosoft played a significant role in building this multi-platform experience spanning iOS, Android, Web and Fire TVs. Their team comprises an extremely dedicated bunch of folks with a keen problem solving approach and under the stellar leadership of Ravi Teja, Jay Shah, Srinidhi Rao and Pooja Bal, they have been the kind of dependable partners that a lot of brands would be fortunate to have. I wish them and their team the best for their future.
Deepak Porayath former Head of Bangalore Operations at CapitaLand India

Mobile App Development Review from Deepak Porayath
Our experience working with Robosoft has been quite good in terms of product and outcomes. With our CapitaStar@Work app for India business, the end goal was to bring our customers and their employees onto a digital platform. The objective was to integrate our solutions such as visitor, parking, and ticketing system management into a single app. CapitaStar@Work caters to our requirements and surely will make life simpler for our users. I would recommend Robosoft to others because it is a good organization to implement technological interventions in any traditional manufacturing, real estate, or brick-and-mortar industry.

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
