Test Case vs Test Scenario – Difference Between Them (2024)

Test Case vs Test Scenario – Difference Between Them? ›

The main difference between test cases and test scenarios is that test cases are specific instructions that can be used to test a particular function or feature of an application, while test scenarios are high-level descriptions of how a specific function or feature of an application should work.

The developed test cases are covererd all the fuctionality of the application we can say test cases are enough. if you knows the functionality covererd or not you can use RTM (Requirement Tracebility Matrix). Because of that RTM have facility we mapped that all the test cases to the given module.

A Test Coverage Analysis would reveal that there should be a Minimum of 8 Test Cases to cover both sides of each edge condition. Note: testing at an edge is fraught with test stimulus accuracy concerns so testing near each edge is typical and also covers at least two test conditions for each equivalency class region.

Assess the quality of existing tests.

Having a high number of test cases but large areas of your application untested may indicate that the test cases aren't well structured to cover the features of the application.

Additionally, it may be more efficient to batch similar test cases together. Some forum users claim you can write 20-30 daily for normal test cases. For medium test cases, 10-15 per day, while for complex test cases, you can write 4-7 per day.

Therefore, to achieve 100% decision coverage, a second test case is necessary where A is less than or equal to B which ensures that the decision statement 'IF A > B' has a False outcome. So one test is sufficient for 100% statement coverage, but two tests are needed for 100% decision coverage.

Number of Test Cases = (Number of Function Points) × 1.2

Once you have the number of test cases, you can take productivity data from organizational database and arrive at the effort required for testing.

(The reasonable number of Test Cases varies from 500 to thousands. The number 1100 test cases can be completed in 6-month project duration). What document did you refer to write the Test Cases? Answer: Requirement document.

A simple template for test cases

This is a fairly common structure that contains a number of important points. The test case has multiple test steps, some of which have expected result and some which do not. You should have 3-8 test steps in a test case.

What is considered a good test case? ›

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.

Test case efficiency: Test case efficiency is a measure of how effective test cases are at detecting problems. Defects finding rate: It is used to determine the pattern of flaws over a period of time. Defect Fixing Time: The amount of time it takes to remedy a problem is known as defect fixing time.

Use cases are executed by business users or by external software. Test cases are executed by QA testers. Test cases are designed by test engineers. All steps are to be executed together in a use case and end result is important.

To cover all the possible sequences for Path Coverage we need 4 test cases: TC1: Condition 1 - T, Condition 2 - T (A-B-E-F) TC2: Condition 1 - T, Condition 2 - F (A-B-G)
