Quality assurance software testing company
Quality assurance (QA) is meant to verify that your solution corresponds with the requirements and addresses the users’ needs. For nearly a decade, Yellow has been here to help you test your mobile or web applications and make sure they work like clockwork.
Our QA engineers are ready to apply best practices, tools and the latest technologies to help you establish concrete control over your product’s life cycle by monitoring every development stage and giving you accurate product quality information.
Our QA services
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.
Common automated tests include:
UI
While conducting UI testing, engineers focus on visual and graphic-based elements of the software product like toolbars, fonts, buttons, menus, text boxes, and more to ensure that all UI functions are bug-free and work exactly as they are designed.
API
As the name suggests, these cases focus on an application program interface’s (API) functionality, security, performance, and reliability, as well as on business logic and the security of the application and data responses
Performance
The goal here is to determine the stability, speed, scalability, and responsiveness of an application, as well as to find bugs and then fix them to ensure the software product holds up under a given workload.
Security
At this stage, QA engineers look for vulnerabilities, possible loopholes, and weaknesses in the system which might result in a data leak or disrepute to the business. Given that data is the new gold of the 21st century, security testing should never be neglected.
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.
Common manual tests include:
Acceptance
The purpose of acceptance testing is to determine the degree to which the software product meets the user's needs and evaluate the system's compliance with the business requirements.
Unit
During unit testing, the small pieces of code remain in focus to ensure that the software development process is flexible and agile.
Integration
At this stage, QAs check the software modules as a group. This is usually the second level of the software testing process after the previous one.
System
This level examines the fully integrated and complete software product. QA engineers put the product in an environment that closely mirrors production to verify whether it meets the technical, functional, and business requirements.
Share your problem, and we’ll find the best way to solve it. The consultation is free & has no commitments.
When do you need QA services?

How we test software products at Yellow
At Yellow, we follow a pyramid strategy to make sure your software works like clockwork.
Unit tests level
They are applied to small pieces of code to ensure they work as expected. In other words, unit tests isolate a section of code (function, module, or object) and verify its correctness. They are specific, quick to execute, help to fix bugs early in the development cycle, and save costs. One of the biggest advantages is that unit tests can serve as project documentation.
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 and users won’t have any problems while interacting with it. 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.
We provide software quality assurance services for all types of platforms
Yellow’s QA specialists will make sure that your users enjoy the smooth and bug-free performance of the application regardless of the platform.
Mobile
Our QA team will make sure your application works and looks as it should on all devices and all platforms. We test the app’s usability, performance, and security to provide users with a functional solution.
Web
At Yellow, we provide QA services for various types of web apps. Whether it’s a huge cloud-based marketplace, a progressive web app, or a small landing page, everything will be checked with the same level of scrutiny.
Desktop
QA engineers at Yellow will put your software into different conditions to analyze its conformance with behavioral requirements, quality specifications, and hardware compatibility.

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.
