What is Boundary Value Analysis?

From the apps on your phone to the software programs on your computer, all these technical mediums are end products that a group of developers works from hours on end to create. But before these applications make their way to your personal devices, they undergo a series of tests to check their major and minor functionalities.

Like everything else in life, programmers make errors in the form of bugs as well. These errors are sometimes encountered during the process of software testing which must be identified to ensure that the program would be of top quality upon its release. Quality assurance and quality control are two of the most important elements to obtain customer satisfaction, which is why using the right testing methods is extremely necessary.

Defining Boundary Value Analysis

We all know that being a programmer isn’t the most exciting job in the world. You spend countless hours per day working to develop the right code, only to spend another couple of hours trying to fix a bug that’s hard to find. But even when you’re finished with your code, you must focus your attention towards quality assurance. You may also check out sales analysis examples & samples.

Quality assurance (QA) is an important part of web and software development. Without it, users are bound to be left with nothing but cheap and poorly-made websites with no guarantee of proper data handling and network security. Knowing this, it’s safe to say that QA isn’t the easiest job in the world, either. You may also see analysis examples in word

However, delivering the best software testing services requires a whole lot of work to conduct. Imagine the amount of data that software testers need to work with just to make sure a program works exactly how it’s supposed to with no room for errors. Thus, there is a great need to use simple yet effective techniques to work with these test cases at a quicker rate. One example of these techniques include boundary value analysis.

In the world of software testing, boundary value analysis (BVA), also known as ‘range checking’, is a black box testing strategy that relies on test cases. This test is conducted to check whether there are any bugs found at the boundary of the input domain. This is great for testing the boundary value between valid and invalid boundary partitions as well. The given technique is an easy and quick method to spot any input errors that could possibly interrupt the performance of a particular function or the program as a whole.

1. Advantages of BVA

Apart from being incredibly efficient to use, the boundary value analysis technique is also a lot easier to remember due to its uniformity and automated nature. Expenses for testing may even be controlled by limiting the number of test cases identified. This technique can also reveal any potential user interface (UI) or user input troubles found in the software. Boundary value analysis is an ideal approach to use when the functionality of a program is based on numerous variables that represent physical quantities. Because errors are typically observed in the extreme ends of the values inputted (such as Start- End, Lower- Upper, Maximum-Minimum, Just Inside-Just Outside values), these boundaries must be checked well to prevent any further errors from occurring during user interaction.

2. Disadvantages of BVA

Unfortunately, this black box test design technique also has its fair share of disadvantages. For one, it isn’t as effective when dealing with Boolean variables. There may even be cases where the technique would fail to test all the potential values, making the results slightly unreliable. This can be a problem when testing for errors, as inaccuracy can sometimes lead to further or unforeseen problems in the program. You may also like process analysis examples & samples

3. Boundary Value Analysis and Equivalence Partitioning

Equivalence partitioning is also a type of black box test design technique that involves dividing the input data into multiple ranges of values and then selecting one input value from each to calculate the effectiveness of the given test cases. Since there are many possible test cases involved in software testing, reducing this infinite number to a finite number makes it easier for testers to come up with precise results. And because this technique follows a specific formula to follow, it ensures testers that the selected test cases are considered to be effective test cases that can cover every possible scenario.

Based on how equivalence partitioning is defined, it’s clear that boundary value analysis and equivalence partitioning are two similar techniques that can be used alongside one another at all testing levels.

Despite the cons that exist with using boundary value analysis, it still remains one of the preferable testing methods for many companies and experts that deliver software testing services. This is an ideal technique to use when testing a large pool of test cases individually is nearly impossible to conduct given the time and resources available. So when push comes to shove, using this black box test design technique will be an easier and quicker way to cover test scenarios effectively. You may also see needs analysis examples
