Without knowledge of essential testing types, you risk hindering your career in software testing. In this blog, we’ll explore the importance of understanding the two main methods of software testing in detail.

Which are the Two Main Methods of Software Testing?

Software testing is generally categorized into two main methods that dictate the testing infrastructure and tools needed.

1. Manual Testing

In manual testing, the software solution is evaluated for bugs and issues by a tester who performs the assessment manually, without relying on any automated tools or infrastructure.

How Does Manual Testing Work?

In manual testing, the QA (Quality Assurance) team uses defined test objectives to create test scripts for each specific scenario. These test cases are designed to assess the software’s behavior against the expected outcome, and the testing process involves a test engineer manually verifying the software’s performance to detect any bugs or errors.

Manual testing typically involves five stages:

  1. Unit Testing: In this stage, the testing team verifies the individual units of the source code.
  2. Integration Testing: Multiple units are integrated and tested together in this stage.
  3. System Testing: This stage tests the software to verify if it meets the desired requirements.
  4. UI Testing: GUI testing is performed to ensure that the software interacts with the user in the intended way.
  5. Acceptance Testing: This stage assesses whether the whole system functions as intended in the real world.

2. Automated Testing

Automated Testing is a testing approach that utilizes automation tools to evaluate the quality and performance of software. Instead of manual testing, the test cases are executed by a software testing team or a QA engineer using automation tools to identify any potential issues or defects in the software solution.

How Does Automation Testing Work?

Automation testing works by first creating a software testing suite and inputting it into the automation testing tool by the QA engineer. After the test suite is automated, multiple tests can be run on it. The developer can then replay, check, and make necessary improvements to the software based on the results obtained.

Below are the five stages involved in the process of automation testing:

  1. Test tool selection: The development team selects an appropriate testing tool for automating the process.
  2. Project Scope: Identify the end objectives and goals of the testing process, and determine suitable outcomes.
  3. Design and Development: Create test cases, plan the automation’s in/out scope, and determine the deliverables.
  4. Execution: Input data is added to the test scripts and executed.
  5. Maintenance: It is important to continually assess the test suite to determine if new functionalities need to be added for testing.

Manual testing can be divided into two main categories, which are functional and non-functional testing. These categories are based on our experience of delivering bug-free software solutions.
