Buyer's Guide


How To Choose the Right Software Testing Company for Your Business?

Software testing is a very important process to ensure that the quality and functionality of software are up to the mark before they are released to the market and used by concerned people. 

Software testing is primarily performed to identify and fix bugs, errors, security vulnerabilities, performance issues, and user experience problems. However, it is also a complex and time-consuming process that requires the best QA companies at the helm. Therefore, it is advisable to outsource software testing to offshore companies that can provide quality assurance services.

But how do you select the best software testing company for your project? There are many factors to consider that will help to select the ideal one: 

  • Company’s reputation and experience
  • The quote they offer for software testing services
  • The technical expertise they possess
  • The software testing tools they use
  • The software testing time they take, and 
  • The support they provide after testing software. 

Here, we will discuss each of these factors in detail and provide some tips on evaluating and comparing different software testing consultancy agencies.

Reputation and experience

One of the primary factors to look for when choosing a software testing company is its reputation and experience in the IT industry. A reputable and experienced agency will have a proven track record of delivering high-quality QA services to various clients across different industry verticals and platforms. You will also find positive reviews and testimonials from their previous and current clients; furthermore, it is also better if they possess industry certifications and accreditations to showcase their capability and competence.

How you do that: To check the reputation and experience of a software testing company, you can do some online research and visit their website, social media pages, blog, portfolio, case studies, awards, etc. You can also ask them for references and contact some of their past or existing clients to get feedback on their work quality, communication, reliability, and satisfaction.

Additionally, you can gauge their expertise from their total years of experience in software testing. Plus, the number and size of projects they have completed, and the types of software testing services they offer in myriad industry domains shall also give you a fair idea.

Price

Most of the reputed software testing agencies shall provide you with a free quote for their charges. Outsourced software testing services are affordable as compared to in-house software quality assurance testing, especially in first-world countries. Software testing can be costly depending on your project's scope, complexity, duration, and requirements; hence, you need to find a software testing consultancy that can offer you a reasonable and transparent pricing model that suits your budget.

How you do that: To compare the prices of different software testing companies, you need to request a detailed quote or proposal from each of them that outlines the scope of work, deliverables, timelines, resources, tools, methodologies, testing and QA process, etc. You also need to clarify what is included and excluded in the price, such as additional fees or charges for revisions, changes, support, etc. 

On the other hand, you may also look for the pricing model they offer: 

  1. Fixed-price: you pay a fixed amount for the entire software testing project
  2. Time-and-materials: you pay based on the actual hours spent and materials used for QA testing, or 
  3. Value-based: you pay based on the value or outcome delivered on the entire software quality assurance testing of the product

Technical Expertise

Technical expertise refers to the knowledge and skills of the software testers who will work on your project. They should have adequate qualifications, experience, training, and certifications in various aspects of software testing such as test planning, design, execution, reporting, automation testing, etc. Software testing experts should also be acquainted with the latest trends and best practices in quality checks as well as the particular technologies and tools that are specific to your project.

How to do that: To assess the technical expertise of a software testing company, you simply ask them about their team composition such as how many testers they have. Furthermore, what qualifications i.e., degrees or certifications they hold and what types of testing skills they have can make a big difference. It is also crucial to know the tools i.e., what software testing tools they use along with methodologies (such as software development life cycle or agile frameworks they follow). 

Alternatively, you can also ask them to provide samples or examples of their previous work or projects that are similar to yours in terms of complexity or domain; furthermore, you can conduct technical interviews or tests with some of their testers to evaluate their competence and proficiency.

Software testing tools they use

Software testing is comprised of several types of testing methods mentioned below: 

  • Functional testing, 
  • Usability testing, 
  • Security testing, 
  • Performance testing, 
  • Compatibility testing, etc.

Each type of software product testing needs different tools and frameworks to execute and automate the test process; hence, you should select a software testing agency with expertise and experience in using the tools and frameworks specific to your project. For instance, if you are developing a web app, you may want to hire a software testing company that uses tools like Selenium, Cypress, TestCafe, etc. Likewise, if the project is a mobile application development, you may choose from the best QA companies that use tools like Appium, Espresso, XCUITest, etc.

Software testing time they take

Software testing can be time-consuming and affect your project’s delivery time and budget. Therefore, you should look for a company that tests software products by providing you with an accurate and transparent estimate of the software testing time they will take for your project. 

How to do that: You can straightforwardly ask them about their software testing process and methodology. Plus, clarify how they ensure the quality and efficiency of their quality check services. For instance, you may hire software testing consultancy services that follow agile software testing principles and practices through continuous integration, delivery, and test-driven development. Such practices can help reduce the testing time and improve the software quality by enabling faster feedback loops and early defect detection.

Support they provide after testing software

Software QA testing is not a one-time activity that ends after the software product is delivered to the market. Software products may need to be updated or modified based on user feedback, market changes, new requirements, etc. Therefore, you should look for a software testing service provider that can provide you with ongoing support and maintenance after testing your software product.

How to do that: You should ask them about their communication channels and methods plus how they handle bug reports and change requests. For instance, top software testing companies use tools like Jira, Slack, Trello, etc. for managing and tracking their software testing projects and tasks. These tools can help facilitate effective communication and collaboration between you and your software testing partner.

Choosing the right software testing company for your project can be challenging and requires careful research and evaluation. However, considering these points, you can narrow down your options and find a reliable and professional software testing company to meet your quality assurance needs.
