Best Software Testing Services Companies In Vietnam

Because we all make mistakes, the job of Software Testing services in the development process is required. Some of these mistakes are minor, while others are costly or dangerous. We must double-check everything and anything we generate since mistakes are unavoidable – humans make mistakes all the time. This is why the relevance of QA software testing services and software testing services is increasing.

1. What Are Software Testing Services?


It is the process of analyzing an application or software to ensure that it meets the necessary and specified requirements. Along with the development phase, the entire software and QA testing procedure are carried out. Furthermore, software testing services assist businesses in delivering quality products by eliminating software errors and problems.

2. Types Of Software Testing Services

2.1 Automation Testing

This has dominated the testing sector in recent years since various free source and paid automation testing technologies are utilized to uncover faults and bugs. The process of software automated testing entails writing test scripts, running them, and logging issues in defect management software.

2.2 Manual Testing


It is the process of testing software by humans to ensure the quality of the software, for which exclusive test cases are written and tested for pass or fail status. Some of the most frequent types of manual testing are smoke testing, functional testing, and sanity testing.

2.3 API Testing

Every program has three layers: a data layer, an API layer, and a user interface (UI) layer. Because it contains crucial business logic, an API is the heart of an application. It lets front-end users interface with the back-end and ensures the software’s proper operation. API testing is typically used to validate the functionality, dependability, security, and performance testing levels or the more generally known API layers. Because this layer has direct access to the data and display layers, it is critical to test the service layers using API testing.

2.4 Web & Mobile QA

A mobile web application is a software that can be viewed using a mobile browser, which means you don’t have to download it to your device to use it. Mobile web applications, like web apps, are typically designed with JavaScript, CSS, and HTML5; however, there is no standard software kit. Web apps for mobile use, in contrast to other mobile applications, are easy to design and test, but they are typically far more rudimentary in terms of capability.

2.5 Security Testing

This form of quality assurance testing involves a variety of testing methodologies and is used to validate the program as a whole in terms of software, hardware, and networks. It typically evaluates the whole integrated software product in order to verify end-to-end system specs.

It enables testing, validation, and verification of both the application architecture and the business requirements to ensure a fully functional solution. Though there are over 100 different types of software testing, some of the most frequent QA software testing services types have been documented and generically classified as functional and non-functional testing techniques in this article.

2.6 Performance Testing


This is an essential non-functional testing method that is used to assess product readiness under the influence of heavy loads. It employs careful testing processes to verify the responsiveness, reliability, and stability of the software program under changing user loads.

It is often accomplished by evaluating the application under test’s response times, throughput, and resource utilization levels.

2.7 QA Consulting & Analysis

Quality Assurance (QA) Analysts play an important role in software development. They are in charge of testing programs to ensure that they are reliable, functional, and user-friendly. Both automated and manual testing can be used for QA. Choosing the optimal type will depend on the organization’s needs and capabilities.

Manual testing is typically utilized for smaller projects with limited budgets. QA Analysts review lines of code and check the functions of all regions inside the overall program for any flaws that may damage the end-experience user’s during manual testing. They act as each type of human who will interact with the completed program (i.e. customers, clients, etc.) as part of the testing process to ensure that it performs as intended. When the QA Analyst is finished with their work, they report their findings so that improvements can be made, and then they test the program again to ensure everything is proper.

2.8 Software Testing Process


Traditional Waterfall Development Model

In 1970, Winston Royce invented the waterfall development approach. It is one of the most traditional models. It is a step-by-step model that defines all stages of the Software Development Life Cycle.

  • This paradigm states that testing is performed by an independent group of testers.
  • Each stage must be completed before moving on to the next.
  • Stages cannot be combined.
  • After all of the functional requirements have been determined, testing begins.

In the past, the Waterfall Development paradigm was primarily used. Despite the fact that it promotes the creation of extensive documentation at each phase, the Waterfall Development Model has a number of drawbacks that make it unsuitable for usage today.

  • Bugs can only be fixed during the testing stage.
  • It is an unsuitable strategy for large-scale initiatives.
  • Documentation consumes a significant amount of time.
  • In this paradigm, the testing stage comes quite late in the Software Development Life Cycle.
  • The client’s feedback is not taken into account during the development phase.
  • Errors that occur after the software development process has been completed create a great deal of grief.

Agile Model


The Agile Model is a new method to software development. It emphasizes on breaking down activities into smaller iterations rather than long-term planning.

At each stage, software engineers create unit tests. Every failed test is followed by the creation of code to make it pass.

Tests are carried out on a continual basis and are updated as new bugs are uncovered. The goal of this architecture is to facilitate continuous integration while also lowering failure rates.

The Agile Development Model has the following advantages:

  • frequent deliveries
  • constant communication with clients
  • efficient designs
  • requirement fulfillment
  • changes can be made anytime.

Model V


This paradigm performs development and test execution processes in parallel. It’s a set model. It categorizes software testing into five stages:

  • Unit Examining
  • Testing for Integration
  • Regression Analysis
  • System Evaluation
  • Testing for Acceptance

This methodology is simple to use because planning and design are completed before coding. As a result, it saves time and increases the likelihood of success.

Spiral Model


The Spiral Model is the same as the Agile Model. However, it concentrates on risk assessment. The assembly of needs and risk analysis takes place at the bottom, while upper spirals form above it.

As the model concentrates on risk analysis, the likelihood of avoiding dangers increases. It is a better approach for complex software because new features can be added later.

However, it is pricey, and the risk analysis must be performed by experts.

3. Why Should You Outsource Software Testing Services?

The global software testing services market is expected to increase by USD 34.49 billion between 2021 and 2025, at a CAGR of more than 12% over the forecast period. The study provides an up-to-date analysis of the current market landscape, as well as the most recent trends and drivers, as well as the general industry environment.

The market is fragmented, and this trend will continue during the projected period. Some of the key market participants are Accenture Plc, Atos SE, Capgemini SE, Cognizant Technology Solutions Corp., DXC Technology Co., HCL Technologies Ltd., International Business Machines Corp., Infosys Ltd., Tata Consultancy Services Ltd., and Wipro Ltd. The growing popularity of mobile testing will provide enormous growth prospects. Market suppliers must improve their presence in fast-growing segments while retaining their positions in slow-growing segments in order to capitalize on present opportunities.


Why You Need Software Testing Services:

The development phase is not the end of the software development project. Before it can be released, it must go through a series of software testing procedures. If you don’t have an experienced in-house software testing team or if your current team is small, outsourcing QA software testing services is far better than developing your QA team from scratch.

The following are the advantages of outsourcing software testing and QA software testing services, as well as how to take use of them:

Expertise Is Available

When you outsource software testing, you will be able to select the best people from software testing outsourcing organizations that specialize in your areas of concern. Our experience will not only assist you in launching a more full, functional product, but we will also be able to advise you on your software testing method and strategy.

You can review our track record of successfully completed software testing projects, as well as our testing team’s skill set and spectrum of experience, to see if we are familiar with the specifics of your generated software product or a similar one.

Quicker Results

Another motivation to outsource software testing is if you are results-oriented. An outsourced software testing team can react, scale, and report in incredibly efficient timeframes because they already have knowledge, automation scripts, and a large array of devices in place. Different time zones, for example, can be advantageous to your organization. In our experience, we frequently run and provide findings in Asia while our clients in Europe and America are sleeping. As a result, the time required to complete the software testing life cycle will be reduced.

To get the most out of outsourcing, make sure the testing crew is accessible throughout business hours and even after hours in emergency scenarios. This is especially important when the software product is nearing completion.

Operations With A Specific Goal

For your in-house staff, software quality assurance might be a demanding responsibility. So, by outsourcing software testing, your organization may concentrate on the development process and other important business operations. Your in-house IT team’s workload will be reduced, giving them the bandwidth and productivity they require to produce powerful, meaningful software solutions. Furthermore, your outsourced team will be able to meet your deadlines without putting additional strain on your own team.

If you entrust us with a portion of your operations, we will ensure that we deliver a comprehensive array of software testing services to meet your needs, such as validating functionality, installation compatibility, performance testing, scalability, security, and user approval. Other activities that should be recognized include providing information about the testing process being implemented and the use of real-time defect tracking systems, as well as the usage of a thorough roadmap for the assigned process and testing tools as approved by your management team.

New Point Of View

An editor must review a writer’s work, no matter how good it is. The same may be said of software developers. Software testing outsourcing businesses, such as Testing Hero, will be able to detect issues that your company’s employees may have missed. We can provide you with an independent and objective assessment of your software product’s strengths and flaws.

Aside from providing you with a new perspective, we have a genuine and dependable QA administration system in place. We have a mature, tried-and-true approach that is in line with industry best software test best practices. In accordance with this, we will create metrics and deliver real-time project status via status reports, graphical presentations, and other team-to-team collaboration approaches (if you ask us to do so).

Enhanced Testing Quality

When outsourced software testing services, software testing service providers must follow the principles and aims of the organizations that outsource them. As a result, outsourced software testing service providers like us will ensure that the desired quality is achieved for software products competing in a dynamic business landscape. Furthermore, we can ensure you that top industry techniques are used to validate your software solutions.

However, in addition to paying attention to testing quality, look for suitable security measures to prevent leaks and thefts and to protect intellectual property rights. Look for ISO certificates, which can provide reassurance that best software test best practices are being followed.

Cost Savings

Working with software testing outsourcing firms like us allows you to save money, resources, and time. It is a significantly less expensive option than internal hiring, training, and providing adequate resources to a new or developing team.

4. What Is Software Testing Life Cycle (STLC)

The term “Software Testing Life Cycle” refers to a testing procedure that includes defined phases that must be completed in a specific order to verify that quality objectives are satisfied. Each action in the Software Testing Life Cycle process is carried out in a planned and systematic manner. Each phase has its own set of objectives and deliverables. Distinct organizations have different Software Testing Life Cycle phases; nonetheless, the foundation remains the same.


4.1 Requirement Phase

Analyze and study the requirements throughout this portion of the Software Testing Life Cycle. Hold brainstorming sessions with other teams to determine whether or not the requirements are testable. This step aids in determining the scope of the testing life cycle. If a feature cannot be tested, disclose it during this phase so that a mitigation approach can be developed.

4.2 Planning Phase

In most cases, the initial step in the testing process is test planning. During this phase, we identify the actions and resources that will assist us in meeting the software testing services objectives. During the planning process, we also strive to determine the metrics, as well as the technique for gathering and tracking those metrics.

On what basis is the planning carried out? Only necessities?

NO, is the answer. Requirements are one of the foundations, but there are two other critical elements that influence test preparation. They are as follows:

– Put the organization’s strategy to the test.

– Risk assessment, management, and mitigation.

4.3 Analysis Phase

This STLC phase specifies “WHAT” will be tested. The test conditions are primarily identified through the requirements document, product risks, and other test bases. The test condition should be able to be linked to the requirement.

Several factors influence the identification of test conditions:

– Testing levels and depth – Product complexity – Product and project risks

– Involved in the software development life cycle.

– Test management – Team skills and knowledge

– The availability of stakeholders.

We should try to write down the test conditions as thoroughly as possible. For an e-commerce web application, for example, a test condition could be “User should be able to make a payment.” You can also specify, “Users should be able to make payment via NEFT, debit card, and credit card.”

The most essential benefit of writing specific test conditions is that it enhances test coverage since the test cases will be developed on the basis of the test condition, and these details will drive the writer to write more complex test cases, which will eventually increase coverage.

Determine the exit criteria of the testing as well, i.e. the situations under which the software testing services will be terminated.

4.4 Design Phase

This stage specifies “HOW” to test. This stage entails the following tasks:

– Describe the test condition in detail. To increase coverage, divide the test conditions into many sub-conditions.

– Identify and collect test data – Identify and configure the test environment

– Create the traceability metrics for the requirements.

– Create metrics for test coverage.

4.5 Implementation Phase

The preparation of detailed test cases is the primary effort in this STLC phase. Prioritize the test cases and decide which ones will be included in the regression suite. Before concluding the test case, it is critical to do a review to confirm that the test cases are correct. Also, don’t forget to sign off on the test cases before the actual execution begins. If your project includes automation testing services, choose the candidate test cases for automation and begin scripting the test cases. Don’t forget to go over them again!

4.6 Execution Phase

As the name implies, this is the phase of the Software Testing Life Cycle where the actual execution takes place. However, before you begin your execution, ensure that your entrance requirement is met. Execute the test cases and record any discrepancies in the defect log. Fill up your traceability matrix at the same time to track your progress.

4.7 Conclusion Phase

The exit criteria and reporting are the focus of this STLC phase. Depending on your project and stakeholders’ preferences, you can select whether to send out a daily report or a weekly report, and so on.

There are other types of reports (DSR – Daily status report, WSR – Weekly status report) that you can send, but the main thing to remember is that the substance of the report varies depending on who you are sending your reports to.

If your project manager comes from a testing background, they will be more interested in the technical aspects of the project, thus including these in your report ( number of test cases passed, failed, defects raised, severity 1 defects, etc.).

However, if you are reporting to senior stakeholders, they may not be interested in the technical details, so focus on the risks that have been addressed by software testing services.

4.8 Closure Phase

Closure activities include the following tasks:

– Verify that the test has been completed. Whether all of the test cases are executed or deliberately mitigated. Check that no faults of severity 1 have been opened.

– Hold a meeting to discuss lessons learned and write a lesson learned document. (Include what went well, where improvements are needed, and what may be improved.)
