Happy Broccoli Games's Review Sourced from Google
Agnieszka and Kai translated both of our Duck Detective games and did a phenomenal job!
They were great to work with, quick to respond and the players love the translation.
These games were particularly difficult to translate, since they include puns and word puzzles.
We were hesitant to attempt a localization at all, but we felt in good hands, since Agnieszka and Kai redesigned some of the puzzles and explained to us in detail how they would make sense for a Chinese audience.
We will come back for future games for sure :)

I highly recommend Agnieszka and Kaja's translation services :)
Great translation quality, detailed approach, and excellent communication! They also performed QA testing for the game for us, so I highly recommend the full package.

Frozen Way's Review Sourced from Google
Agnieszka and Kai collaborated with us on the localization of two video games, demonstrating a high degree of professionalism and flexibility in using the specific platforms and tools used throughout the process. Although the translations weren't the easiest, they were completed very efficiently and delivered to excellent quality, with the texts themselves tested after being implemented in the games. Throughout the project, we could always count on additional comments and clarifications, as well as valuable suggestions for translating specific phrases. At every stage of the collaboration, it was clear that game localization is not just a job, but also a true passion for Agnieszka and Kai. We look forward to working with Chinese Localization again in the future!

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
