Software Testing Write For Us – Types of Software Testing: Differences and Examples
Oct 16, 2020 | Tech Tips, Performance Tests
Software challenges are integral to the software development life cycle (SDLC). If problems creep into the production environment, they more expensive and time-consuming than they are to fix. Testing is the way you can be sure about functionality, performance, and user experience. Whether you perform your tests manually or through automation, the sooner and more often you can test, the more likely you are to identify bugs and errors, not only valid you and your lineup from potential fire drills later on but also by making sure that your software submission has been thoroughly reviewed and audited before it is in the opposite of your users.
Software testing can be divided into two distinct types: functional and non-functional testing. Different software application parts require other kindness, such as performance tests, scalability tests, integration tests, unit tests, and many more. Each type of software test offers excellent application visibility, from code to user experience. We will go into the details of some of the most communal types of software testing.
Types of software testing: functional and Non-functional tests
Functional tests are carried out to verify business-critical features, functionality, and usability. Testing ensures that the software’s features and functionality behave as expected without any issues. It validates the application against the conditions mentioned in the Software Requirement Specification (SRS) document. Functional test types include unit tests, interface tests, regression tests, plus many more.
Unit tests are the first tests developers perform throughout the development phase. testing focuses on testing individual pieces/units of a software bid early in the SDLC. Any function, procedure, system, or segment can be unit tested to determine its correctness and expected behaviour.
Integration challenges involves testing different modules of a software submission as a group. A software submission comprises various sub-modules that work organized for multiple functionalities. The purpose of combination testing is to validate the integration of other modules and identify bugs and issues related to them.
Non-functional tests are like functional tests; however, the main modification is that those functions are tested under load for observer performance, reliability, usability, scalability, etc. Non-functional tests, such as load and stress tests, are typically performed using automation tools and solutions, such as LoadView. In addition to performance testing, non-functional testing types take in installation testing, reliability testing, and haven difficulty.
Performance taxing is non-functional testing performed to determine a software application’s speed, stability, and scalability. As the name suggests, the general purpose of this test is to check the performance of an application against different system and network benchmarks such as CPU utilization, page load speed, maximum control traffic, server resource utilization, etc. Within performance testing, there are several other types of tests, such as load tests and stress tests.
How these test types diverge from each other
You may have some idea about the different types of tests above. All the tests focus on the reliability and readiness of software applications; however, let’s better understand the differences between them through some examples. Let’s say you have an eCommerce website/app with standard functionalities. Here are some examples of performance tests, functional tests, integration tests, and unit tests:
If you want to pattern how your website will complete when a high numeral of users come to your website, for specimen during sales season, you should perform load tests, which fall under the category of performance tests. Its motivation helps you detect speed and stability issues and eliminate potential performance bottlenecks.
Suppose you want to validate input and output for individual functionality such as registration, login, add to cart, checkout, payment processing, database inputs, etc., based on test cases written in the SRS document. In that case, you should perform functional tests.
If you want to validate the cart’s functionality with the checkout and checkout module integration to see if the sum of items added to the cart is purchased correctly with the correct payment, you should perform integration tests.
If you have written a module for merchandise upload and want to check if it is correct and the products are added correctly without any errors or defects, then you should perform unit tests for the module.
Functional tests are performed to validate all functionalities. Integration tests validate the interaction between different modules, and unit tests are done to check if individual pieces of code are correct. In short, performance tests are carried out to check the website’s performance.
Advantages of these types of test
- Evaluate the speed and scalability of the website/application.
- Identify bottlenecks for performance improvements.
- Catch errors that are missed in functional tests.
- System optimization and feature improvements
- It guarantees the reliability of the website under heavy load.
- It makes sure that the website/application is free from defects.
- Guarantees the expected behaviour of all functionalities.
- It guarantees that the architecture is correct with the necessary security.
- Improves quality and general functionalities.
- Minimizes business risks associated with the website/application.
- It ensures that all application modules are well integrated and work together as expected.
- Spot interconnected issues and conflicts to resolve them before creating a big problem.
- Validates functionality, reliability and stability between different modules.
- Catch ignored exceptions to improve code quality.
- Supports the CI/CD pipeline.
- Early detection of errors in new functionalities or features developed.
- Minimize testing costs as problems are detected early on.
- Improve code quality with better code refactoring.
- Supports the agile development process.
- It Simplifies integration and allows for good documentation.
Disadvantages of these types of tests
As all of these test types improve functionality and enhance the user experience, there are no downsides to doing this. The only thing you might consider as a downside, in general, is the time and cost of testing. Testing requires effort and resources, and there is a risk associated with inaccurate test results. However, not doing website/app testing will put you in a compromising position that can significantly hamper your business and reputation.
The right time to perform this type of test
Performance testing is a must in all advance and production atmospheres to ensure that your website or application is up to date and can handle the anticipated user load. Handy testing should done with each build to validate all changes and functionality against the specifications and requirements. Unit tests should performed whenever they finish writing code to validate correct input and output. Integration testing should done when integrating a new code snippet with some other module to ensure there are no conflicts and they work together correctly.
Tip: A hand-in-hand approach
Although each test type seems like a separate task, you can intelligently combine them to achieve higher product quality. Let’s take an example.
Let’s say you’ve created a new web page; running a load test (performance test) with LoadView for that web folio as a unit test will ensure that when you do the final build with all the folios, the website even now optimized for handling high user load in peak traffic scenarios. This means that you have your performance testing as part of unit tests. A hands-on approach like this will help you reduce problems early on and save you a great deal of charge and time in the long run.
What is LoadView?
LoadView is a cloud-based load testing that checks your website’s performance under high-traffic conditions. Simulate thousands of virtual users across multiple browsers and devices from different geographic locations to create the most realistic environments for your performance tests. It also offers a point-and-click trial script construction facility with EveryStep Web Recorder that does not require coding skills, so anyone on your team can create scripts and perform load tests. You can assess your website, application, web pages and third-party API with LoadView to detect performance bottlenecks and quickly resolve them. LoadView quickly gets on track, and its concert reports are easy to understand with tortious acumens.
Conclusion: Types of Software Testing
Performance testing is necessary for all change and production environments to ensure that your website or application is up-to-date and can handle the expected user load. Functional testing should finished with each build to validate all changes and functionality against the specifications and requirements. Unit tests should performed whenever they spend writing code to validate correct input and output. Integration testing should done when integrating a new code snippet with some other module to ensure there no conflicts and they work together correctly.
