2 min read

In the realm of software testing, understanding the concepts of Test Basis and Test Cases is pivotal for conducting comprehensive and effective testing.

Let's delve into these concepts with a refined perspective:

Test Basis

­ All documents from which the requirements of a component or system can be inferred. The documentation on which the test cases are based. If a document can be amended only by way of formal amendment procedure, then the test basis is called a frozen test basis.

Key Points about Test Basis:

  • Inference of Requirements: The Test Basis serves as a repository of information that allows testers to deduce the requirements of the system or component under examination.

  • Documentation Foundation: It forms the bedrock for creating test cases, providing a structured and reliable reference for testing endeavors.

  • Frozen Test Basis: When amendments to a document necessitate a formal procedure, the Test Basis becomes "frozen," ensuring stability and consistency throughout the testing process.

Test Case

­ A set of input values, execution preconditions, expected results and execution postconditions, developed for a particular objective or test condition, such as to exercise a particular program path or to verify compliance with a specific requirement.

Key Points about Test Cases:

  • Comprehensive Elements: A well-structured test case encompasses not only input values and expected outcomes but also considers the conditions preceding and following execution.

  • Objective-Driven: Each test case is tailored to fulfill a specific objective or test condition, contributing to the overall testing strategy.

  • Path Exploration: Test cases can be designed to traverse particular program paths, ensuring a thorough examination of the software's functionality.


In conclusion, a robust understanding of Test Basis and Test Cases is indispensable for conducting effective testing processes. The Test Basis provides the necessary groundwork, while well-crafted Test Cases serve as the instruments for thorough testing.

The symbiotic relationship between these concepts ensures a structured and reliable approach to software testing, ultimately contributing to the delivery of high-quality software products.
