Characteristics of a Good Test Case (2024)

FAQs

What are the characteristics of a good test case? ›

Doesn't do unnecessary things; Explicited pre-conditions; Defined test data input; Clear, concise, and complete (no assumptions in Test Case description, steps, expected result etc.);

The MC-FIRE acronym (Maintainable, Complete, Fast, Isolated, Reliable, and Expressive) may be a helpful acronym to remember these characteristics as you work!

Best Practices for Writing Test Cases

Prioritize clarity and transparency. Be clear, concise, and assertive in describing what the tester needs to do and what results they should ideally get. Focus on End-User requirements when writing sample test cases. Map test cases to reflect every aspect of the user journey.

A well-written test case has enough end to end detail that it should leave you in a state where you could execute it again. Independence. Test cases should be able to stand alone and not depend on a certain sequence of execution with other test cases.

in mind the four essential elements of a good teaching case: context, complexity, ambiguity, and relevance.

A good test should fulfill certain the criteria. There are four criteria of a good test according to some expert; they are validity, reliability, level of difficulty, and Page 4 discrimination power.

A good assessment should be reliable, valid, and free of bias. First, reliability refers to the consistency of students' scores; that is, an assessment is reliable when it produces stable and consistent results.

Positive test cases verify that when the function under test is exercised using valid input, the input is accepted and the user is able to proceed with the flow. Negative testing, in opposition to positive testing, uses unexpected conditions to ensure the functionality does not do something that it should not do.

What is the quality of a test case? ›

Test Case Quality

They should be designed to test each requirement or feature of the software, and should be designed to identify defects in the software. Effective test case creation requires a deep understanding of the software requirements, user stories, and acceptance criteria.

An effective test case design will be: Accurate, or specific about the purpose. Economical, meaning no unnecessary steps or words are used. Traceable, meaning requirements can be traced. Repeatable, meaning the document can be used to perform the test numerous times.

A Test Strategy is a high-level document that outlines the approach, scope, objectives, and methods for testing a software application. It provides a framework for planning and executing testing activities throughout the software development lifecycle.

Test Case Effectiveness = (Defects Detected / Test Cases Run) x 100. Defect Leakage. Quantifies defects missed during testing but found later. Defect Leakage = (Defects Found Post-Testing / Defects Found Pre-Testing) x 100. Defect Removal Efficiency.

A good case report should have quality, novelty, exceptional interest, conciseness, may be about rare disorder and relevant to medical practice. It may provide new information which can be developed into a hypothesis for further testing.

Fair: is non-discriminatory and matches expectations. Transparent: processes and documentation, including assessment briefing and marking criteria, are clear. Reliable: assessment is accurate, consistent and repeatable. Feasible: assessment is practicable in terms of time, resources and student numbers.

This document discusses the key characteristics of effective assessment: validity, reliability, practicality, and accuracy. It defines each characteristic and provides examples. Validity means a test measures what it intends to measure. Reliability means a test produces consistent results.
