Let’s dive in. 

What is software testing outsourcing? 

Software testing outsourcing involves handing over software testing to a third party, usually uninvolved with the rest of the development process. 

The third party could be a specialized company or an individual expert. They put your developed software through appropriate tests to check whether it works as it should. 

They also ensure the end product is free from bugs or code anomalies using Quality Assurance (QA)

Why is this important? 

Poor software quality cost businesses an estimated $2.08 trillion just in 2020

Additionally, the market today is primarily customer-driven. If the customer isn’t satisfied with your product, you’ll incur losses. 

To avoid this situation and prioritize customer satisfaction, you can outsource software testing to specialized teams focused on user experience. 

Outsourcing also allows you to focus on your core business while the QA expert handles the testing process. 

20 commonly outsourced software testing services 

Let’s explore 20 types of testing services your outsourced team can handle. 

1. Ad hoc testing 

The testing team aims to find errors and test software functionality through random, unplanned, and informal testing. 

2. Agile testing

Performed by a QA team, it follows the Agile testing methodology and looks at the software from the customer’s perspective. 

3. API testing 

As part of Integration Testing, this test aims to check if the software’s APIs (Application Programming Interfaces) meet the necessary reliability, functionality, performance, and security requirements. 

4. Automation testing 

Here, the computer uses the relevant automation testing tool to set up the environment, execute the test, and produce quick results

5. Black-box testing 

A QA team focuses on software functionality without prior knowledge of said software’s internal workings. The tester simply provides the input and observes the output. 

6. Compatibility testing 

This test shows how well the software performs under different environments, e.g., other network systems. 

7. Functional testing 

Functional testing is a form of black-box testing. Here, your software goes through numerous test cases to establish whether it works as expected. 

8. End-to-end testing 

The test aims to mimic real-world software usage by focusing on user experience. It tests the complete application by interacting with different hardware, databases, applications, and systems. 

9. Integration testing

The testing team combines individual software modules to test them as a group. 

Since different programmers and coders may have developed separate modules, this test checks the communication level among all these units.

10. Localization testing 

The team checks whether a globalized application or software is appropriately localized for a given region, e.g., if your English mobile application supports Mandarin language characters. 

11. Manual testing

A testing team member acts as a user to manually check the software/application for bugs. No automation testing tool is used.  

12. Non-functional testing 

This test checks all aspects of the software that functional tests don’t, e.g., reliability, scalability, performance, and usability. 

13. Penetration testing 

Usually conducted by specialized penetration testing companies, this method evaluates your network or system security by simulating a malicious attack. 

14. Performance testing 

The QA engineer evaluates whether the system complies with its specific performance requirements as a form of functional testing.  

15. Regression testing

The test confirms whether a software code change has affected existing features and functionalities. Ideally, it shouldn’t. 

16. Recovery testing 

The team tests how well your software can recover from crashes and hardware/software failures. 

17. Security testing 

This test aims to identify any loopholes, vulnerabilities, threats, or weaknesses in the software system that could lead to information loss. 

18. Usability testing 

Typically done by end-users, the test checks how easy it is for users to navigate and operate the software. 

19. Vulnerability testing 

The main objective is to assess vulnerabilities that can impact performance, reliability, and integrity and prevent such issues.

20. White-box testing 

Unlike black-box testing, here, the software developer is aware and knowledgeable about the software. So, the focus is to test the internal structures of the software rather than pure functionality. 

As you can see, there are many different types of software testing services available. 

If you’re still unsure about outsourcing testing, let’s look at some of its benefits.

5 key benefits of software testing outsourcing

QA outsourcing can be a strategic business decision benefitting you in the following ways. 

1. Cost-effective 

Training existing employees or testers to stay updated and at par with software testing experts can be expensive. 

According to one estimate, it can be anywhere between 15% to 25% of your total project cost. 

By outsourcing, you can experience cost savings in multiple ways: 

  • Human resources: No need to hire or train testers. 
  • Data and hardware: The team will already have the latest tools of the trade. 
  • Time: An experienced team will deliver a high-quality product in a short time frame.  

Since the vendor is responsible for all the above, you can pick available talent at the price point that works best for your bottom line. 

2. Efficient and systematic testing 

A QA service provider will have experts trained in manual and automation testing. They can use these different methodologies to test your software and ensure it’s working to its maximum potential. 

Similarly, in any given QA company, you’ll probably find experts in various domains. 

For example, let’s say you have an e-commerce website and a corresponding mobile app. You can probably outsource both web and mobile testing to the same company. 

These engineers will know how to create effective test plans, which QA process to follow, and implement specific testing procedures. 

You can employ the same mobile testing team to run regression tests on your app after each update, allowing you to maintain a consistent user experience and software quality.

Another advantage of outsourced QA testing is that you gain a fresh perspective. 

It can be easy for your internal team to lose objectivity during the development process. Outsourcing to a third-party team can give you unbiased test results, helping you stay aware of areas of improvement. 

3. Increased access to talent

When you have a single focus, you can invest all your resources in that area. The same goes for the QA service provider. 

Since this is their expertise, they’ll stay updated on new technologies, test automation tools, and changing market trends. Their team will also consist of experts with varied skillsets and hands-on experience to accommodate different client testing needs. 

If your existing software product requires updates to keep up with trends, the team will know what to do and how to do it. 

Some companies also offer consultancy services and can guide you regarding new software launches. 

4. Faster time to market 

Most software testing outsourcing companies have a predefined workflow, process, and methodology. 

So, they already know how to provide a high-quality service in a short period, cutting down your launch time. You can also double your company’s productivity by outsourcing your testing activity to a company in an opposite time zone. 

For instance, if you’re in the US and outsource to India, the significant time difference will mean that someone is always working on your project. This will allow you to launch your product faster. 

You can also leverage this international team to easily enter new markets and localize your products for these audiences. 

5. Focus on your core business 

Software QA testing can be a strain on your in-house IT team. 

However, an outsourced team can help reduce this burden by taking over your testing project. They’ll do so while adhering to deadlines and reducing your overall project cost. 

Increased availability of valuable in-house resources can help you focus on scaling up your organization and creating more products. 

3 risks of outsourcing software testing (with solutions)

Let’s explore three potential risks of outsourced software testing and its solutions. 

1. Security concerns

There are obvious concerns when sharing source codes, customer data, reference models, and workflows with another company. Without proper documentation, the third party can plagiarise or even leak proprietary trade secrets to your competitors. 

Solution: You should sign an NDA (Non-Disclosure Agreement) with the development team. 

The document should detail project goals, testing strategies, and ownership of data. It can also specify if the team can use an open-source, third-party code or not. 

Any credible QA testing service provider will agree to sign an NDA and would’ve probably done so with other clients. 

2. Cultural barriers and miscommunication 

Your outsourced QA testing team may be located in another country, across different time zones. 

An obvious challenge here is a potential difference in work ethics, communication styles, and even a lack of English proficiency. All these can lead to miscommunication and misunderstandings that can derail the progress of your project. 

Solution: A simple way to overcome this challenge is by choosing a vendor who works with clients from your country. 

If they have already worked with someone from a similar background, they’ll be aware of the differences and know how to minimize them.

Another way is to over-communicate and repeat each detail multiple times. You can also ensure that every interaction has a written record for you and your offshore team to reference later. 

3. No clear timeline

A common concern with outsourcing is the lack of a precise schedule. 

Often, offshore testing companies work at different times, leading to confusion regarding timelines. The QA team assigned to your project may also have other projects in the pipeline, so a lack of structure can lead to a delay in your project. 

Solution: You should always ask your service provider for an estimated timeline for the project’s completion. You can help the team by stressing urgent requirements they should prioritize first. 

You can also mention specific deadlines in your contract, especially a tentative end date. Doing so will help everyone stay on top of things. 

5 simple tips for effortless software testing outsourcing 

Here are five tips to help you work with a good software testing outsourcing company:  

1. Clarify your needs

You need to be clear about your project needs, such as whether you require manual or automated testing. Details like the project length and how many testers you need can also help you find the right testing partner. 

2. Check the vendor’s credibility

Ensure you look at the service provider’s website to see what kind of work they do. 

These websites will also often hold references, case studies, and test documents to help you make an informed decision. 

3. Consider niche teams

If you have a specific requirement, for instance, testing a mobile gaming app, you need a company experienced in the same. 

In this case, taking your time to find a suitable QA outsourcing service will save time and money in the long run.

4. Create achievable goals

Every testing team requires measurable goals, so they know what to work towards. 

For QA testing, you can set some Key Performance Indicators (KPIs), like tracking active defects, that can help both you and your team measure your progress. 

These metrics will vary from a case-to-case basis.

5. Check into outsourced team’s productivity 

It can be easy to feel out of touch with your software testing partner. 

You may not have a clear view of how things are progressing or even if they are! 

Thankfully, productivity management software such as Time Doctor can help you out here. 

It will help you stay aware of how the outsourced team is working. The software can also help you manage your outsourced team’s payroll with ease.
