Difference between Manual and Automation Testing

Difference between Manual and Automation Testing - IntegerByteBlog

In this blog, we will discuss the difference between manual and automation testing. Software Testing is a crucial part of the Software Development Life Cycle (SDLC). Software Testing is the quality assurance checkpoint within the SDLC.

It meticulously examines the software’s functionality, performance, and security, ensuring it operates as intended and meets user expectations. The primary goal of software testing is to identify defects, errors, or missing requirements in contrast to the actual requirements.

Below are the points which describe difference between Manual and Automation Testing:

Manual Testing:

  • Definition: Manual testing is a type of testing in which we do not use any tools (automation) to perform the testing.
  • Execution: Test cases are executed by human testers step-by-step without relying on test scripts or automation tools.
  • Process: Testers create test cases, test the software, and provide the final report about the software.
  • Time-Consuming: Manual testing is time-consuming because it is done by humans, and there is a chance of human errors.
  • Use Cases: Manual testing works well for testing functionalities, user interface, website behavior, application behavior, user acceptance, and user experience.
  • Benefits:
    • Easy hiring: Anyone can perform manual testing.
    • Fast feedback: Provides quick and accurate feedback.
    • Versatile: Manual test cases can be applied to many scenarios.
    • Flexible: Adapts easily to changes in the user interface.
    • Less expensive: No need to invest in automation tools.
  • Limitations:
    • Not all defects detected: No assurance of 100% test coverage.
    • High expertise required for complex cases.
    • Time-intensive: Developing manual test cases for full coverage takes time.
    • Cannot be recorded for reuse.
    • Less reliable due to human error.

Automation Testing:

  • Definition: Automation testing uses tools (automation) to perform testing.
  • Execution: Test cases are executed by software tools and frameworks.
  • Speed: Automation testing is faster than manual testing.
  • Resources: Requires automation tools and scripts.
  • Use Cases: Suitable for repetitive tasks, regression testing, and large-scale projects.
  • Benefits:
    • Speed: Faster execution of test cases.
    • Consistency: Reliable and repeatable results.
    • Reusability: Automated test scripts can be reused.
    • Coverage: Can achieve higher test coverage.
  • Limitations:
    • Initial setup effort: Requires investment in automation tools and framework development.
    • Not suitable for all scenarios: Some tests require human sensibilities.
    • Maintenance overhead: Scripts need updates as the application changes.

In summary, manual testing is perform by humans without automation tools, while automation testing relies on tools and scripts for execution. Each approach has its advantages and limitations, and the choice depends on project requirements and goals.

Hope, above points helps you understand the difference between manual and automation testing.
