Can Outsourcing Automated Testing Support Your Business?

Outsourcing automated testing offers significant benefits to companies such as cost savings, access to specialized expertise, and improved efficiency. To help you get the most out of outsourcing QA test automation, here is a guide to the entire process.

What is Test Automation as a Service (TAaS)?

Test Automation as a Service (TAaS) is essentially hiring an external company to handle some or all of your software testing. This company brings its own expertise, tools, and infrastructure to automate the testing process, making it a more efficient and often more comprehensive approach than managing it all in-house. It’s similar to traditional outsourcing, but TAaS typically means the provider takes on more complete ownership of the process, from strategy and execution to reporting, freeing up your internal team to focus on other priorities.

TAaS vs. Outsourcing vs. Crowdsourcing

While TAaS, outsourcing, and crowdsourcing all involve using external resources for software testing, they differ in their approach and level of control. Think of TAaS as a more hands-off version of outsourcing. With traditional outsourcing, your team is typically more involved in the daily management of the testing work. TAaS, on the other hand, is more of a turnkey solution—you define the goals, provide the software, and the TAaS provider handles the rest. Crowdsourcing uses a different approach altogether, leveraging a large network of testers to identify bugs and usability issues. This can be useful for getting diverse perspectives but can also be less structured and predictable than TAaS.

When to Use and When *Not* to Use TAaS/Outsourcing

TAaS can be a game-changer for many organizations, but it’s not a one-size-fits-all solution. Here’s a quick guide to help you decide if it’s right for you:

When to use TAaS:

• To accelerate software releases: TAaS can significantly speed up the testing process, allowing you to get your product to market faster.
• If you lack in-house expertise: If your team doesn’t have the specialized skills or bandwidth for automated testing, TAaS can bridge the gap.
• For specialized testing needs: If you require specialized testing, such as IoT testing or compliance testing (e.g., HIPAA), a TAaS provider can offer the necessary expertise and tools.
• To get an unbiased perspective: An external TAaS provider can offer a fresh, objective assessment of your software’s quality.
• To leverage cloud-based testing infrastructure: Many TAaS providers offer cloud-based testing environments, eliminating the need for you to invest in and manage your own infrastructure.

When not to use TAaS:

• For small, short-term projects: The setup and integration involved in TAaS might outweigh the benefits for small projects with tight deadlines.
• If software testing is your core business: If testing is a central part of your company’s value proposition, it might make more sense to build and maintain your own in-house testing capabilities.

Other factors, like data re-entry, operational downtime during testing, strategic analysis sessions to address critical bugs, error tracing, and iterative testing, can also contribute to cost overruns. A contingency plan and open communication with your testing provider can help mitigate these risks.

Cost Reduction Strategies

Outsourcing to locations with lower labor costs can be a cost-effective strategy. Clearly defining the scope of work, prioritizing test cases, and leveraging automation also optimize spending. Negotiating favorable contracts with testing providers and using open-source testing tools can further reduce expenses.

Four Main Cost Categories

Software testing costs typically fall into four categories: prevention costs (activities to prevent defects), detection costs (identifying defects), internal failure costs (fixing defects before release), and external failure costs (fixing defects after release). Understanding these categories helps allocate resources effectively and prioritize quality assurance.

Cost Estimates

Hourly rates for software testers vary based on location, testing type, and the tester's role. Researching typical rates for your needs helps create a realistic budget and evaluate proposals from outsourcing providers.
