In this post, we’re going to know what exactly reliability testing means in software testing, the importance of reliability testing and its types in detail. So if you were looking for a quick guide on reliability testing, then you are at the right place. Let’s not delay things and get started!
What is Reliability Testing?
Reliability testing is a testing technique to test the functionality of software under given circumstances within a specified period of time. This technique helps identify software design errors that need to be rectified to support seamless software operations for the intended purpose. It checks whether the software is working smoothly without any failure operation in a particular environment and makes sure that there are no bugs and errors for its expected purpose.
In today’s quickly evolving technological sector, the usage of software applications is increasing in every aspect of our life – including telecommunication, fintech, healthcare, government sectors, etc. The objective of reliability testing is to identify the pattern of failures, its occurrence in a specific period of time, and the root cause of failure.
Thus, we can say that reliability testing is essential to have accurate data on which the users can be dependent. Its aim is to standardize the software quality and the software products that we are building. If we have the ability to repeat the test cases and get the same output multiple times, then the product is reliable.
Lastly, it is important to perform reliability testing for every software that is developed and never ignore it as it makes sure that the software is created as the requirements, satisfies the purpose for which it is made, and is capable enough to render an error-free operation.
In the end, its motto is to provide quality software.
Objectives of Reliability Testing
- To build a robust and reliable product that works perfectly every time.
- To find errors and resolve them before the software is delivered and released.
- To make sure that all the customers are satisfied and all its requirements are achieved.
- To uncover issues in the product's design and functionality.
- To unlock latest design patterns in the defect trends.
What is the importance of Reliability Testing?
1. Test-retest reliability
Reliability testing is one of the main phases of software development, which is performed to estimate test-retest reliability only a few days or weeks apart before the software is released. The time here is restricted so that the skills of examinees in the area can be assessed easily. The connection between two administrators and the examinee’s scores is estimated through statistical correlation, where reliability testing takes place to illustrate the preparation of a plan that is consistent and generates stable scores across time.
2. Improve software performance
When you hire a dedicated team of software developers, you'll definitely get your product at a satisfactory level which can be useful. But when they perform reliability testing, it works much better and enhances the performance of the software. Performing reliability testing is essential not because it satisfies the customer, but because it makes sure that all the functions involved in it are working as per the requirements or not. If not, then they will recheck it and come up with more efficient solutions to present it to a client.
In short, reliability testing makes sure that the user receives the best possible and expected experience for a business and bug-gree aspect. But unfortunately, one minor error or bug can highly affect your software and lead to complex consequences which can be difficult to handle and perform continual dependability testing.
3. Decision consistency
After performing test-retest reliability testing, we are now all set to get the examinees results whether we have passed it or failed. The result of reliability testing and classification decisions is estimated depending on the software consistency.
4. Bugs and issues resolution
In the process of software development, bugs are a basic thing that might or might not occur during the execution of the program. But make sure you are resolving each bug before launching the software even if there are minor errors. Sometimes it might take longer to detect bugs while building large-scale software, but don't just hop on to the next level ignoring reliability testing as it is an essential part of the software development process.
Types of Reliability Testing
There are different modules through which the test can be run. They are:
1. Feature Testing
A particular feature of the software is tested where the execution and interactions of functions is looked upto. Each function is executed at least once to check its operationality and efficiency. Moreover, interactions of functions within should be checked. Basically it is a process of software testing where there are various testing variations of a feature that determines the best user experience and validates new features for application.
2. Regression testing
Regression testing is a type of software testing technique used by testers to verify any update or modification in a software. All the alterations are made in such a way that it does not affect the overall functionality of the software. This is used on introduction of a new feature into the software when no bugs are left to debug into the system. This test is done upon every change or addition or subtraction of a feature in order to make sure it does not hinder the existing functions' operations.
3. Load testing
Load testing is a practice of modeling expected usage of software by allowing multiple users to access it at the same time. This system is more suitable where there are numerous users simultaneously. Usually, the software in the beginning works within the desired efficiency but as time passes and the workload increases, decline in the efficiency is seen. In order to track the work-load a software can handle and the outcome it gives, load testing is done onto it. It is used to check the performance of the software having peak work-load.
Key Takeaway
So that's it for the blog. In closing, we would like to mention that Reliability Testing is expensive as compared to the other forms of software testing. So in order to make this testing process less expensive, make sure to have a well-documented test plan and test management by your side. In the process of software development life cycle, reliability testing plays an essential role that brings reliability to the product and predicts the software future. Sometimes it is really difficult to retain software reliability if the complexity of the product is high.
If you are still not sure about the security of your software, then make sure to hire a dedicated software development team who are skilled and experienced enough to follow all security measures and perform testing so that no bugs and errors are seen.
