Software Testing Company Hiring Guide
What is a software testing company?
A software testing company is a company that provides quality assurance (QA) solutions and services for applications and programs. It plays a critical role in the software development process by assessing the reliability and performance of digital products before and after deployment, thus ensuring quality and seamless user experience.
QA testing companies do so by employing a wide range of testing methodologies to address the specific needs and challenges of various industries. They also offer scalable testing solutions to accommodate projects at various stages of development to assure a thorough and effective testing process.
One of the key challenges software testing companies face is identifying issues early in the development stage to minimize risks and maintain a seamless process. This includes adapting to diverse client requirements across various industries, from startups to enterprises, and offering tailored QA solutions to meet these specific demands.
The industry outlook suggests a robust growth trajectory for the global software testing market, which is projected to reach $90.39 billion by 2030. This forecast underscores the escalating demand for QA services and highlights the industry's significant growth potential.
What do software testing companies do?
Software testing companies evaluate software programs to make sure they function as intended and meet user needs. Software testers can detect various errors such as bugs, vulnerabilities, or usability problems so developers can easily fix them, and the software can perform well in real-world conditions.
Some of the specific services provided by QA testing companies include:
- Functional testing
Validating that the software behaves as expected and all features work according to specifications - Integration Testing
Testing how different modules or components of the software work together - Performance testing
Evaluating the software's speed, scalability, and stability under various conditions (e.g., high user loads) - Security testing
Identifying vulnerabilities and ensuring the software is protected against potential threats, such as hacking or data breaches - Usability testing
Assessing how user-friendly and intuitive the software is for end users - Compatibility testing
Verifying that the software functions across different devices, operating systems, browsers, and networks - Automation testing
Using automated tools to test repetitive tasks and improve efficiency, often for regression testing - Manual testing
Relying on human testers to explore the application and detect issues not easily found by automated tools - Regression testing
Ensuring that new updates, features, or bug fixes do not disrupt existing functionality - Quality Assurance (QA) consulting
Providing strategies to improve the overall software development and testing process
What are the different types of software testing?
There are several types of software testing, each serving specific purposes. Based on the particular testing methodologies applied, software testing can be divided into manual testing and automated testing:
Manual Testing | Automated Testing |
Human testers execute test cases step by step | Scripts and tools are used for test execution |
Complex scenarios, exploratory testing | Repetitive tasks, large-scale testing |
Thorough but time-consuming, prone to human errors | Efficient, provides broader coverage, faster feedback |
Minimal coding required | Requires coding for script creation and maintenance |
Manual updates and maintenance | Ongoing maintenance of scripts and test environment |
In the age of AI, further software testing categorization can be discerned, namely black box testing, white box testing, and gray box testing.
Technique | Description |
Black Box Testing | Focuses on testing the functionality of the software without knowing its internal code or structure. Testers simulate user inputs and validate outputs. |
White Box Testing | Involves testing the internal code, structure, and logic of the software. Testers have access to source code and design specifications for thorough testing. |
Gray Box Testing | Combines elements of both black box and white box testing. Testers have partial knowledge of the internal code and use it to design comprehensive tests. |
How much do app testing companies charge for their services?
The cost of software testing typically ranges from $50,000 to $250,000 of the total development budget. Software testing companies charge for their services based on factors, such as company location, expertise, and project requirements.
The top 50 software testing companies on DesignRush charge an average of $43/hour. Among these, 7.4% accept projects with budgets under $1,000 catering to simpler QA testing projects, while 5.5% require a minimum budget of $50,000 or more for complex, enterprise-level projects.
Meanwhile, here's the average hourly rate of QA testing companies based on the testing type:
- Functional testing: $15-$30 per hour
- Compatibility testing: $15-$30 per hour
- Automation testing: $20-$35 per hour
- Performance testing: $20-$35 per hour
- Security testing: $25-$45 per hour
Why should I hire a QA testing company?
You should hire a QA testing company because it knows how to prevent flawed software or technology from reaching your customers, safeguarding your business's reputation and profitability.
For instance, releasing a new app with critical security vulnerabilities can lead to a massive data breach, and expose your users' personal information. An incident like that would result in financial losses, a damaged reputation, and eroded customer trust.
Tech companies partner with reliable QA testing companies because they:
- Employ a team of professionals skilled in diverse testing methodologies, tools, and techniques
- Use the latest tools for automation, performance testing, and security assessments
- Identify and resolve bugs early in the development process, reducing costs and delays
- Leverage automation tools to streamline repetitive tasks, saving time and resources
- Reduce the risk of costly failures or negative user feedback post-launch
- Streamline the testing process to accelerate the development cycle and meet release deadlines
- Ensure the software works seamlessly across various devices, platforms, and environments
- Minimize the risks of crashes, data breaches, or poor user experiences
- Adhere to and stay updated with industry best practices and standards
Success story
Launching a software or app doesn’t mean the end of testing. Our experts have chosen this case study to demonstrate how continuous testing ensures smooth feature releases while effectively eliminating defects and errors:
- Challenge: A fintech client's Buy Now, Pay Later (BNPL) web application was in active use, but the testing team couldn’t ensure comprehensive testing for new features. The client also wanted to improve efficiency and test coverage by incorporating test automation into the existing process.
- Solution: ScienceSoft’s test engineer conducted thorough manual functional and regression testing across various platforms and browsers. Test automation was postponed due to the complexity of the software's payment functionality. Instead, the client prioritized developing and manually testing new features. The QA testing company also enhanced the quality of user stories by improving existing backlogs and setting a standard for writing new ones.
- Results: After over eight months of testing, ScienceSoft’s tester eliminated numerous functional and UI defects. This effort significantly streamlined the release process for new software modules, which improved efficiency and product quality.
How do I choose the best QA testing company for my business?
Choosing the best QA testing company for your business involves several key steps to ensure you find a reliable and competent partner:
- Define your requirements
Identify the type of app testing services you need (e.g., functional testing, performance testing, security testing, etc.), the platforms your app supports (iOS, Android, web), and any specific industry standards or regulations you must comply with. - Research potential companies
Conduct thorough research to identify potential software testing companies that meet your criteria. Use online directories like DesignRush, industry forums, social media, and recommendations from colleagues or industry peers. - Evaluate their experience and expertise
Assess the experience and expertise of each QA testing company. Check its portfolio, case studies, client testimonials, and reviews to see if it has a proven track record of successfully testing software or apps like yours, preferably in your industry. - Ensure they follow best practices and standards
Confirm that they adhere to industry standards and best practices for software testing, such as ISO/IEC 29119 or ISTQB certification. They should follow secure testing practices to make sure your software’s security is thoroughly assessed, especially if sensitive data is involved. - Make a shortlist
Create a list of prospective companies that you would like to work with based on your requirements and then send a detailed request for proposal (RFP) to every candidate. - Set up an interview
Schedule an interview with your potential software testing companies to get to know them better and to further discuss your project. You can estimate if they’re the right fit based on the initial conversation. - Rate their communication and collaboration skills
Assess their communication and collaboration practices. A good QA testing company should maintain transparent communication, provide regular updates and progress reports, and be responsive to your queries and feedback. Evaluate their communication channels, project management tools, and frequency of status meetings. - Discuss cost and budget
Consider your budget and the cost of software testing services offered by each company. Their quotes or proposals should outline the scope of work, deliverables, timelines, and cost breakdown. Compare the pricing structures but prioritize quality and expertise over the lowest cost. - Consider flexibility and scalability
Evaluate the flexibility and scalability of the QA testing company. It should be able to accommodate changes in project requirements, scale up resources when needed, and adapt to evolving technology trends. Inquire about its ability to handle multiple projects simultaneously and its capacity to meet tight deadlines. - Check for compatibility and integration
Ensure the software testing company can seamlessly integrate with your development team, processes, and workflows. It should understand your project goals, timelines, and priorities and align their testing efforts accordingly. Discuss how its team handles collaboration, feedback incorporation, and issue resolution during testing.

What are the key success metrics in software testing?
Here are some important metrics to track for successful software testing:
- Test coverage
The percentage of the total code, functionality, or requirements that have been tested - Defect density
The number of defects (bugs) found per unit of code or functionality, usually measured per 1,000 lines of code (KLOC) or function points - Defect detection rate (DDR)
The rate at which defects are identified during the testing phase, a higher defect detection rate indicates an effective testing process - Test execution progress
The percentage of planned tests that have been executed during the testing cycle - Test case pass rate
The percentage of test cases that pass successfully compared to the total number of test cases executed - Defect severity and priority distribution
Categorizing defects by their severity (e.g., critical, major, minor) and priority (e.g., high, medium, low - Defect leakage
The number of defects that were not identified during the testing phase but were discovered after the software was released - Test cycle time
The amount of time taken to complete one full testing cycle (from planning to execution) - Mean time to detect (MTTD)
The average time taken to identify a defect after it is introduced into the system - Mean time to repair (MTTR)
The average time it takes to fix a defect after it has been identified, a lower MTTR indicates that issues are being addressed quickly - Test efficiency
Measuring how effectively tests are finding defects relative to the number of tests run - Customer satisfaction
Measuring how satisfied end users are with the software's performance, usability, and overall quality - Post-release defects
The number of defects found after the software has been released into production
What red flags to watch out for when hiring software testing companies?
Beware of these red flags when hiring a software testing company:
- Inexperienced or underqualified team
Be cautious of software testing companies with no relevant certifications or qualifications, or skilled professionals, as it may impact the quality of testing. - Limited industry knowledge
Avoid a company with no experience in your specific field or technology stack because it may not be able to adequately address your unique testing challenges. - Poor communication and responsiveness
Don't work with QA testing companies that exhibit delayed or inconsistent responses, it can indicate poor customer service and may be a sign of an unreliable partner. - Lack of transparency
If the company is unable to explain its testing process, tools, or methodologies clearly, it could indicate a lack of expertise or professionalism. - Overly low or unclear pricing
Don't consider a software testing company that offers services at a price significantly lower than competitors because that could mean that it cuts corners or lacks the necessary resources and tools. - No clear process or methodology
Beware of companies that don't clearly outline their approach to testing (e.g., test planning, execution, reporting, etc.), it could suggest disorganization or lack of structure in their work. - Inadequate reporting and tracking
If the QA testing company doesn’t offer detailed reports or provide clear insights into the testing process, it can be difficult to track progress and identify issues. - Inability to scale or adapt
Avoid the company that only handles projects of a certain scale or cannot adapt to changing project requirements, as this would limit the success of larger or evolving projects. - No focus on security or confidentiality
Disregard a software testing company that doesn’t have clear policies for maintaining confidentiality or secure handling of your code, intellectual property, or user data, as this poses a significant risk. - Overpromising results
Be wary of companies that make exaggerated claims, such as guaranteeing completely bug-free software or offering perfect results without a detailed testing process. - Lack of post-testing support
A QA testing company that doesn't provide post-release support, bug fixes, or maintenance may leave you vulnerable to issues once the software is live. Continuous testing after software updates is crucial.
What questions should I ask QA testing companies before hiring one?
Ask these relevant questions when hiring a software testing company to make sure it meets your needs and expectations:
