Black box testing and gr.ay box testing are two key types of software testing that can be used to find bugs and problems in a system. Each has its advantages and disadvantages, so it’s important to understand the differences between them before deciding which is best for your needs. In this blog, we’ll look at the key types of black-box testing and gray box testing, along with some examples of each. By understanding the differences between these two types of qa testing services, you’ll be able to choose the right one for your next project.
Types of Black Box Testing:
Functional Black Box Testing:
This testing is done to check whether all basic functions of an application are working properly or not. For instance, let’s say you have developed software that can be used for data entry work. A person knowing nothing about its internal working needs to know how it works and what functions are provided in the software.
Example- An e-commerce website is developed. Here a user needs to know how to add items to the shopping cart and proceed for checkout. If these functionalities are working properly, then the testing of this software is said to be successful.
In this testing, one needs to check whether all the existing software functions are working properly as expected or not after any change has been made. Suppose you have developed a data entry program now can check details from only one website and only with a single click of mouse button after some changes have been made in the application whether it can be used to check details from multiple websites and needs more than one click of the mouse. This is Regression testing.
Example- Suppose you have developed an application that calculates the total amount of bills. If needed, calculate the total amount of receipts when items are added or deleted. This is regression testing.
In this type, the tester needs to test that whether the basic functionality of the software work properly or not. For instance, you have developed new software for data entry work, and you need to know if the software is giving expected results or not. This is also popularly called Smoke testing
Example- A e-commerce website is developed. The tester needs to check if all the categories are present. He can search products in all categories or not etc.
This testing is done to check whether the software system under test is working as per user requirement or not. It is done at the developer’s site, and only internal staff will be allowed to participate in this testing.
Example- You have developed an ecommerce website. Now it needs to test by Company’s employees who have experience in using applications like this.
Types of Gray Box Testing:
In this testing, one needs to check whether an application is secure or not. For instance, if you develop the web application need to check for Cross-Site Scripting(XSS), SQL Injection vulnerabilities etc.
Example- A e-commerce website has been developed by you need to check whether it is safe for users.
It is also known as Network testing that how secure the software will be when it goes live in the market. This testing needs an experienced person to perform this testing because the tester needs to check application vulnerabilities by using tools like burp suite, OWASP ZAPetc.
Example- A e-commerce website has been developed by you need to check whether it is secure from network attacks. If the vulnerabilities are found in the application, this testing will only stop after reporting.
In this type of testing, one needs to check how much load an application can take and what performance issues may arise after putting it under load. This testing needs an experienced person to perform this testing because the tester needs to check for memory leaks, excessive database queries, high CPU usage etc.
Example- A e-commerce website has been developed by you need to check how much load can be put on application and whether the performance is up to the mark.
In this testing, one needs to check whether the software is developed as per requirement and can be easily used by its intended users. For instance, if you have developed a new application ecommerce website, you need to check whether the application is user-friendly or not.
Example- A e-commerce website has been developed by you need to check whether it is easy to use.
Gray box testing is done to check how much robust the application is. If you are doing regression, security or sanity testing, it’s called half-baked testing. This test is done by internal staff without involving customers. So need to involve the experienced person in this type of testing as this type of testing needs some tools and tricks to perform this testing. So need to know the tools and tricks used in this type of testing.
