Software testing: Know the difference between alpha and beta testing!

Bugs in software can be expensive and can lead to loss of money and lives. There have been several instances in real life where due to lack of proper software testing, losses were reported. How can one forget the incident when China Airlines Airbus A300 crashed as a result of a software bug on April 26, 1994, which lead to the loss of 264 innocent lives. Another instance was when Starbucks had to close around 60 percent of its stores in the U.S and Canada due to software failure. So, we can see how important it is to prevent software failures. To minimize product failure risk, we use software testing, which plays a major role in IT. Due to its importance, we need to understand its meaning, significance, and types.

So, what exactly is software testing? Software testing is a technique in which the working of software is tested in order to verify that it meets its expectations as per the user requirements. Basically, software testing is done to detect errors in the working model to ensure the accuracy and quality of the product.

Now, let’s look at some of the advantages of software testing followed by its types.

Advantages of Software Testing

There are plenty of advantages of software testing.

Security: It helps to ensure security checks earlier in the development of the product. This helps in preventing some security-related issues after the product launch.

High product quality: Testing guarantees fewer errors and high accuracy as per user requirements.

Customer satisfaction: The client gets a high-quality product, which makes them happy and strengthens the bond.

Saves money: Since testing detects errors earlier in the software development lifecycle and not after the product deployment, it saves time and money after the product is launched.

Great user experience: From productivity rise to better efficiency, software testing helps to meet all the goals related to user experience.

Types of software testing

There are various types of software application testing. Here are some of them:

Alpha Testing
Beta Testing
Unit Testing
Integration Testing
Regression Testing
Smoke Testing
Stress Testing

We would be primarily looking at two important testing types: Alpha Testing and Beta Testing.

What is Alpha testing?

Alpha testing is a type of testing technique done by Quality Assurance (QA) people to test the working of software before its release.

For example, testing of a product is done internally within an organization in presence of a testing environment.

What is Beta testing?

Beta testing is a testing technique that is used to check the functionality of the software by a limited group of users and these users give their feedback for further improvement. In short, we can say a real user test the software in a real environment.

For example, a product is released only for a group of employees of an organization and they give their feedback on the basis of their experience.

Now, let’s look at some of the important differences between alpha and beta testing.

Difference between Alpha and Beta testing

Alpha testing	Beta testing
Alpha testing is done at the developer’s end.	Beta testing is done at the end-user’s site.
Since it is done at the developer’s end, it requires a testing environment or a lab environment.	Since it is performed at the user’s end, there is no need for a testing environment or lab environment.
It is performed internally by the skilled testers of an organization.	It is usually performed by clients who are not part of the organization.
Alpha testing involves the use of both white and black box testing techniques.	Beta testing generally uses the black box testing technique.
A longer execution cycle is required for alpha testing.	Only a few weeks are required for beta testing.
In Alpha testing, features such as reliability and security are not tested in-depth.	In Beta testing, features such as reliability, security, and robustness are thoroughly checked.
This testing focuses on product quality before going to the Beta testing phase.	This testing focuses more on the real-world experience of an application by the end-user.
Developers check for issues and they can immediately fix them or start to work on fixing them.	Here, users provide feedback to the team and then the inputs are generally taken into consideration for future versions.
Alpha testing is done before the launch of a particular product of an organization.	Beta testing is done at the time of marketing the product.

All in all, we have seen the definitions of Alpha Testing and Beta testing techniques with their differences. Overall, we can say that alpha testing deals with the developers testing the software and beta testing deals with real user feedback for further improvements.
