Acceptance Tests

What Are Acceptance Tests?

Acceptance Tests are formal tests conducted to determine if the requirements of a specification or contract are met. In software development, these tests are typically performed at the end of a development phase to ensure the software meets the business requirements and is ready for deployment. Acceptance tests are crucial for client satisfaction and are often conducted by or with the client.

Key Features of Acceptance Tests

  • Criteria-Based: Based on pre-defined criteria agreed upon by developers and stakeholders.
  • User-Centered: Focus on usability and real-world functionality from the user’s perspective.
  • Quality Assurance: Serve as a final verification step to ensure quality and functionality before the product goes live.

How Do Acceptance Tests Work?

  1. Planning: Define the criteria and the scope of the tests based on the product requirements.
  2. Execution: Perform the tests according to the planned scenarios.
  3. Documentation: Document the results and any issues discovered during the testing.
  4. Decision Making: Based on the outcomes, decide whether the product is ready for release or requires further refinement.

Best Practices for Acceptance Tests

  • Involve Stakeholders: Ensure that all relevant stakeholders are involved in defining acceptance criteria.
  • Clear Documentation: Keep clear records of testing processes and results for transparency and future reference.
  • Automate Where Possible: Automate repetitive parts of the testing process to increase efficiency and accuracy.
  • Continuous Feedback: Use feedback from acceptance testing to inform future development cycles.


Acceptance tests are often performed by quality assurance teams, but may also involve end-users or clients to ensure the product meets their needs.

Functional testing is often conducted by developers to check for specific behaviors within the software. Acceptance testing is performed to validate the software against business requirements.
