The system testing is mainly divided into two segments: functional and non-functional tests.

As the name suggests, functional testing tests whether the software’s functions and features work as defined. On the other hand, non-functional testing focuses on aspects like performance, security, usability, and other essential quality aspects.

The following sections have a list of system testing types with quick definitions.

Functional Testing:

Unit Testing

Unit testing is critical early-stage testing, ensuring that individual system components function correctly. For example, calculating prices within the eCommerce store.

Integration Testing

System modules are combined and tested in integration testing to identify interfaces, communications, and data flow defects.

For example, flight details and payment modules work together correctly when a user purchases a flight ticket.

Regression Testing

Regression testing aims to ensure that new code modifications haven’t affected the existing code in any way. Testers conduct a regression test after updating a website’s design to verify that the shopping cart and other functions are functioning correctly.

For example, after adding a new feature in the software, the tester would test that users can still log in without hassle.

Smoke Testing

Smoke testing is a quick check to ensure the basic functionality and stability of the system. It provides the newly deployed web application loads and displays content without errors.

For example, a tester would check if the application starts without critical errors after installing a new software version.

Acceptance Testing

As the name suggests, acceptance testing assesses the software with real business scenarios.

For example, a customer verifies the working functionalities of baking apps by checking if transactions and account management work as expected.

Acceptance testing is further divided into two parts: Alpha testing and Beta testing.

When an in-house team tests the software, it’s referred to as Alpha testing, and when end-users evaluate software, it is known as Beta testing.

Follow the below-mentioned steps to perform a system test efficiently:

1. Prepare a system test plan

The first step of performing system testing is to create a comprehensive document outlining the overall objective of the system testing process.

Include information about the types of tests to be employed and strategies for incorporation according to the company protocols.

Lastly, add the equipment and hardware devices required for each system test.

2. Write your test cases

The next step of performing the system testing includes writing test cases. For example, if you want to assess the effectiveness of a program’s backup storage system, create detailed scenarios for recovery tests.

To keep your documentation actionable, keep the language clear and have a logical organizational structure. Moreover, implement an identification system for test cases to facilitate future retrieval.

3. Create a testing environment

After writing system test cases, defining the physical conditions required for a systematic evaluation process, including configuring necessary hardware and software, is crucial. Ensure consistency within the testing environment to minimize external influence and deliver accurate assessments.

Lastly, simulate a future customer’s environment to enhance user-based tests.

4. Perform testing protocols

Execute each evaluation systemically by adhering to the test plan and utilizing the defined test cases. Record any encountered errors and suggest developers address them through code revisions.

To generate an influential report, adopt an organizational method that aligns with your preferences and requirements.
