QA Testing Services We Offer
Since 2015, Yellow has provided high-quality testing services to all types of companies, from startups to Fortune 500 enterprises. Your software will be verified with top-notch methods and tools. We have solid expertise in the following options:
Automated testing
We develop custom scripts and tailor them to your project requirements. It’s a long-term investment that will facilitate the process and bring huge gains for team efficiency by optimizing routine and recurring tasks.
Manual testing
During manual testing, our specialists look at the application from the user’s perspective. They check everything on various devices to provide the most comprehensive results and analysis.
Functional Testing
Functional testing ensures every feature of your software works as intended from the user’s perspective. We validate core functionality, user flows, integrations, inputs, and expected outputs to identify issues before release and make sure your product performs according to business and technical requirements.
Performance Testing
We determine the stability, speed, scalability, and responsiveness of an application, as well as find bugs and then fix them to ensure the software product holds up under a given workload.
API Testing
We focus on testing an application program interface’s (API) functionality to verify endpoints, data flow, integrations, response accuracy, performance, and security.
Usability Testing
We evaluate how intuitive and user-friendly your product is to help improve user experience and reduce friction.
Security Testing
We identify vulnerabilities, security risks, and weak points to help protect your application, data, and users. We conduct penetration testing audits to identify weaknesses in your application.
System Integration Testing
We test interactions between applications, APIs, databases, and third-party services to identify integration issues early and ensure seamless performance across your entire system.
Ensure your software runs reliably across all connected components.
Software testing process at Yellow
At Yellow, we follow a pyramid strategy to make sure your software works like clockwork.
Unit tests level
We focus on verifying individual components of your application in isolation. We ensure each unit of code performs correctly as expected, helping catch bugs early and improve code quality.
Service tests level
These are applied to various components of the application without involving the UI. This type is meant to validate the API surface of a microservice with databases, queues, caches, and mock HTTP/gRPC endpoints set up locally.
UI tests level
Also known as GUI testing, it’s applied to all parts of the user interface to ensure everything works correctly. Usually, they verify whether the visual elements are functioning according to requirements.
Manual tests level
Can be applied to any part of the app if necessary. Our specialists use custom cases to check the app’s functionality.

What people say
I liked working with them because they were good. With their work, we increased our mobile app’s user usage. We also got reviewed as one of the top 10 employee engagement services in Europe. Their project management was really good. They worked in sprints, and I always communicated directly with their developer. More importantly, they were attentive to our project's details.
Browser compatibility and readability have increased markedly since the engagement began. Yellow's development process helped them beat deadlines and respond quickly to any technical concerns that arose. Their ability to bring creative ideas of their own to the table made them a valuable partner. Yellow typically understood exactly what the issue was and came back with a fix right away.
If you are looking for a partner to collaborate with for the development process, I would consider hiring Yellow. Yellow has an intelligent team of developers that collaborated on the project to build a quality app. They follow instructions seamlessly, respond effectively to feedback, and invest themselves in the overall success of the product. I would happily use them again if we needed developing services.
Yellow is by far the best at helping us make decisions to push our company forward. I’d heard about them through a personal connection in the Bay Area. Yellow stands out because they’re invested in the results and clients. Every single person on Yellow’s team genuinely cares about what they’re doing. I really appreciate that about them and it’s the main reason we will continue our relationship for as long as possible.
Yellow quickly and seamlessly assimilated into a fast-paced and nuanced workflow, completing all deliverables on time. Responsive to questions, updates, and issues, they have streamlined management operations and reduced work backlogs by directing communication to appropriate in-house team members.
The new features have been well received by users. Attentive and flexible, the team excelled at responding to stakeholders in a timely matter. Their technical expertise allows them to propose valuable solutions.
Engaged, supportive, and invested in project success, the team offered constructive criticism, creative guidance, and honest communication. Their user-centered approach resulted in a unique and reliable product that operates well on all systems.
Because of marketing costs, the B2C application fell out of use in favor of a different B2B tool. Yellow was very focused on customer satisfaction, and they participated regularly in standups. They helped solidify features, and they thoroughly explained their process.
We’re impressed with their loyalty and honesty. They were able to stay true to their original quote even though we needed to change and add a few requirements. They’ve done a lot of good work for us on all fronts, but it's amazing to see that they’re able to stick to what they initially promised.
Mainly, I go by client feedback to judge Yellow’s performance, and the clients have been very impressed with their work. The team is exact in what they do, their delivery has been good, and they’re on time and budget.
Their performance was good. I didn’t expect that kind of performance from someone working offsite. I was happy that they completed the project ahead of schedule, so we had some time left to work on additional projects and improvements.
When Yellow is working on a task, they understand how it will impact the product down the line. The team has provided great insight into our processes, making sure we don’t make small mistakes that will impact us in a larger way in the future.
They were very accessible regardless of the time difference as well as communication was good. We had a couple bumps here and there regarding designs that were not originally discussed in our UX/UI designs but they were quick to find solutions as well as any needed changes we requested.
