Product Testing Process and its Types

Introduction to Product Testing

Product Testing is the execution of any number of tests to evaluate a product's performance or qualities. It can, for example, be used to ensure that a product functions properly and is safe for people to use. Depending on the conditions, manufacturers may test their products by an outside laboratory or an organization Team. Often, a formal standard exists for carrying out a specific type of test. If not, engineers may devise techniques to fulfill the testing requirements.

A company can perform product testing at any product creation step, including the idea, development, and manufacturing phases. Before launching a new product to the market, corporations should do at least one cycle of testing, if not more. Another type of product testing is asking people to try a product and getting feedback. However, this article will concentrate on the first sort of product testing — the kind that assesses a product's performance or qualities.

What are the types of Product Testing?

  • Environment testing in product development
  • Regression testing in product development
  • Automated testing in product development

Environment Testing in Product Development

After your development team has created the test cases, run them in the most common setting to check if any problems appear. To complete testing, you should test in every setting where your product will be utilised. It is important to note that "environments" include any characteristic that might affect the efficacy of your product and that the definition will vary based on the sort of product you are creating:

  • Different browsers or operating systems may be present in software environments.
  • Different combinations of hardware may exist in a given environment.
  • The location or severity of patient symptoms may be included in life-sciences settings.
  • Cleantech environments might contain any of the aforementioned, depending on the product.

Regression Testing in Product Development

It is critical to test existing features and new ones while introducing new ones. Although current features have not been modified overtly, new features may unintentionally influence previous features. Testers may confirm that the entire product works as planned by leveraging test cases from previous releases.

Automated Testing in Product Development

The next phase in the maturation and growth of your product is automated testing. This form of testing can be said an extension in the execution of regression tests each time a developer produces new functionality, and a new release happens to guarantee that previous functionality is not broken. Automated testing saves time, but it demands attention to keep it up to date with each new test case.

Why Product Testing is necessary?


Decreased Product Development Time

Decreased Product Development TimeTesting, a product throughout its development cycle, can minimise time to market by catching flaws early on. This saves the firm from going back to an initial phase to find a design or manufacturing process mistake. The findings of product tests can also be used to inform work on the product in subsequent phases of development.

Improved Customer Confidence

Customers will have higher trust in a product that has been tested, especially if a third party conducted the testing. Customers may rely on testing to ensure that a product correctly executes its intended purpose. It also gives investors, third-party partners, standards bodies, and other entities assurance of a product's capabilities.

Enhanced Quality and Reliability

Product testing can assist businesses in improving the quality and dependability of their products. Testing numerous concepts and designs enables a corporation to select the best-performing one, while other sorts of testing aid in identifying and correcting problems to increase reliability. This, in turn, results in a better product and more delighted consumers.

Reduced Costs

Firms use testing to fine-tune their designs and production processes to cut production costs. Detecting problems early in the product development cycle lowers the cost of correcting such issues. Testing a product for quality before releasing it to the market might save firm money on warranty payments and possibly legal fees. It may also contribute to a reduction in the demand for after-sales support.

Increased Profitability

Finally, product testing may increase a company's profitability by lowering expenses and increasing revenues. Product testing may boost sales by increasing interest in a product by presenting testing findings in marketing materials. Improving quality and dependability results in a better product, leading to increased sales.

What are the various stages of Product Testing?

The various stages of Product Testing are described below:

Requirement Development

First, you must decide which items to test and the parts of the product to analyse. Your objectives determine the characteristics you'll need to consider for testing the product.

You must also select the criteria against which you will compare the results of your test, which will assist you in determining if the product fulfils its intended purpose and does so satisfactorily. These requirements may be part of a governmental mandate, an industry-standard, or a contract. In some cases, the producer or testing facility must establish them themselves. The data you acquired in this stage will inform the next step.

Test Plan Development

Following that, you must write a test plan, which is a document that defines the testing technique you will employ. This plan will cover the scope of the tests, the methodology you will employ, the equipment and other resources required, and the testing timetable.

When designing your test plan, it's ideal to be as specific as possible. To ensure the reliability of your test, you must adhere to exact protocols and standards. If you're conducting a test to ensure compliance with a standard, regulatory requirement, or contractual need, that document may be useful in building your test strategy.


The testing environment will then be set up in accordance with the product testing parameters outlined in your plan. Once the testing environment is set up, and all of the essential equipment is in place, you will begin running the tests in accordance with your predetermined plan.

It is critical to adhere to the test strategy throughout the actual testing strictly. You will also need to monitor the exam as needed and document the findings appropriately to verify that the test is completed correctly and the results are reported correctly.

Evaluation of Results

Following the exam, you will evaluate the results and report them. You can investigate any product failures or performance concerns to find the root reason and how to resolve those causes in future design iterations to enhance product performance or prevent product failures. If there were flaws with the test itself, you must examine those issues, modify your test strategy, and redo the evaluation.

What are the uses for Product Testing?

  • Screening Concepts and Designs
  • Checking Compliance With Requirements
  • Establishing Baseline Data for Other Functions
  • Validating Suitability for the Intended Use
  • Ensuring Safety
  • Enabling Technical Communication
  • Forecasting Life Expectancy
  • Providing Evidence for Legal Proceedings
  • Solving Product Problems
  • Improving Products and Production Processes

What are the various methods of Product testing?

The product development testing process verifies that the product works as planned. This testing phase begins when the product objective has been achieved and deployed. Depending on the development process employed, testing will take place at various points during the project:

  • Waterfall methodology: Testing occurs after all product development for the product release has been completed.
  • Agile methodology: Testing begins as soon as an operational requirement (regardless of size) is created.

Testing groups will use several approaches during the testing process to guarantee that the product works as planned. Your testing techniques may differ based on the product you develop, but the basics stay quite similar.

Product testing is beneficial for businesses in a wide range of industries. It may help you achieve various goals, including refining a product, detecting and addressing design flaws in new goods, and ensuring compliance. Companies can test items from the top down, beginning with the entire product or system, or from the bottom up, beginning with individual components. A top-down method may be advantageous since individual component testing are unnecessary if the ultimate output functions effectively. A bottoms-up technique may determine the exact cause of failures or performance difficulties.
