What is System Testing in Software Testing?

What is System testing?

System testing means testing a system as a whole. It is a type of black-box testing where the external working of the software is analyzed using the required documents and it is entirely based on the user’s point of view. It checks the behavior of a fully integrated software that is based on business specified requirements. This type of testing doesn’t need knowledge of code, structure, or internal design. In other words, we can say that all components/elements are integrated to demonstrate if the system works as desired or not.

After Integration testing, software testing companies perform System Testing as it plays an important role in delivering a high-quality product. The main reason behind performing integration testing is that it helps to determine the dis-similarities between the components that are connected and determines the errors both in individual parts as well as the entire system. Software testing is crucial for every software as it discovers defects before the product is delivered to the client and guarantees the quality of the software. It also ensures reliable and high-performance software operation, so make sure you have hired a good software testing company for this job.

System testing is necessary as the majority of testing tasks are performed in this phase. Not only this, but it scrutinizes the whole software system, reliability, functionalities, and other features based on Functional Requirement Specification. It is a set of various tests whose aim is to exercise the entire computer-based system.

Importance of System testing

  1. a) When it comes to software development life cycle System Testing is performed at an initial stage where the entire system is tested.
  2. b) After the first step, it checks whether the system meets all the functional requirements or not.
  3. c) With system testing, you can validate and test the application architecture and business requirements.
  4. d) It is tested in such an environment that resembles the effective production environment where the system will be deployed lastly.

If you’re not aware, then let me tell you that a dedicated team is responsible for system testing performed on a staging server that is the same as the production server. This represents that you are testing systems as good as the production environment.

After discussing the importance of system testing, let us now list out the types of system testing. You’ll find numerous system testing types but we have only listed several types of system testing that a large software development company would use.

Types of System test

Like any software testing system, System tests are also a set of various types of testing that allow developers to validate the overall functionality and performance of the product. Different testing types concentrate on distinct factors of the product and fulfill the requirements of the user. These types of system testing include:

  1. Usability Testing: Usability testing allows you to evaluate a system or service that mainly focuses on the user’s ease of using the product. It checks the ability of the system to achieve its major objectives and has the flexibility in handling controls. It simply means that while the tests are going on, participants will try to complete the most common task while observers watch, listen, and take notes.
  2. Regression Testing: Regression testing is a type of software testing that makes sure to verify any update or modification in software without affecting the other functionality of the product that is made throughout the development process. Basically, it is performed when there is a code modification in a system.
  3. Performance Testing: As the name suggests, performance testing helps to examine the scalability, response, reliability, and other software quality factors, under various workloads. It helps to evaluate how a system performs under a particular workload and also analyze the speed, robustness, and size of the application.
  4. Acceptance Testing: Acceptance testing is a type of testing done by customers or users to determine software requirements and business processes in the last stage of software testing and before making the system available for actual use. This testing phase is important to perform as it decides whether the client approves the product or not, if not then it might not be working correctly that is expected by the user.
  5. Load Testing: Load Testing is a type of software testing that simulates a real-world load on any website or product to study its behavior. It is important in the software development lifecycle as it evaluates how the application performance can be affected by peak and normal loads and helps save money by identifying errors and bottlenecks at an initial stage.
  6. Security Testing: Security testing is a type of software testing that evaluates the security features such as authenticity, integrity, protection, and guarantee of data and information of the software. It discovers vulnerabilities of the system as the resources of the system are protected to keep them away from hackers. It makes sure that the system is prevented from hackers and kept secure to prevent data loss.
  7. Migration Testing: Migration Testing is a type of software testing which ensures that the software moves from older system infrastructure to existing system infrastructure with minimal downtime, no data loss, and data integrity. It also makes sure that all the established functional and non-functional elements of the product are met post-migration.

What are the primary objectives of system testing?

Here are the primary objectives of system testing that includes:

  • The main aim of System testing is to build confidence in the system quality as a whole.
  • System testing verifies whether the system design of the functional and non-functional behaviors is according to the customers’ specifications or not.
  • As we all know, the results of System Testing are then utilized by stakeholders to make better release decisions.
  • System testing checks whether the system is complete and working as per expectations or not.
  • System testing ensures that there are no defects or bottlenecks at this stage so that the information is kept secure.
  • System testing helps you to reduce risk by eliminating that the system will function as per the customer’s requirements.

Wrapping Up

Let’s conclude the software testing topic here. After reading this post, now you might be aware of how important software testing is and why it becomes essential to know the goal. The system testing performance takes place after the completion of software development. It is performed after the product has passed through the unit and integration testing stages as it is a crucial part of the software testing life cycle.

The main reason for conducting the system testing is to check the system and validate that the system is working as per customers’ requirements. The main advantage of this type of software testing is that it tests a single feature of the application and the entire product even when you’re still implementing the features. Hence, you must perform system testing to deliver a flawless user experience to your user.
