1. Structure of the test case:
The main objective of the test is to find defects in the application or system. To achieve this test cases should be written well and should have the below details
1. Test case number
2. Test case name
3. Test case description
4. Pre conditions
5. Test data/Input data
6. Step name
7. Step description/action
8. Expected result
Test case number: A unique number to identify the test case
Test case name: The name of the test case is summary of the test objective typically written in one line.
E.g. For example, if we take the requirement is like below
"Employee creates a document and the manager can either approve it or reject it."
For the above requirement, possible test cases could be
1. Approve the document by manager
2. Reject the document by manager
Test case description: The test case description is generally short description of the test objective written in two or three lines.
E.g. For the test case, Approve the document by manager, the description could be as below
Document is created by an employee and is sent to manager for approval, manager approves the document.
Pre conditions: Pre condition is a condition or predicate that must always be true just prior to the execution of a particular test objective. In other words Pre-Condition is the term itself indicates the Pre existing set of the condition that should be satisfied to perform a particular task.
E.g. for the above test case example, pre condition is document should be created by employee and it should be sent for approval
Test data/Input data: Test Data are data which have been specifically identified for use in tests. It is the data required to test the test case. Input data is to verify that a given set of input to a given function/program produces some expected result. Input can be valid data or invalid data.
E.g. In the above test case example, the test data can be employee user ID and password, manager user ID and password, document details sent for approval, environment details. All this type of data constitutes part of test data/input data.
Step Name: The sequences of actions are given a number to test the correct behavior/functionalities, features of an application called step name. It is like Step 1, Step 2 Step 3….etc. It can also be called as order of execution number.
Step Description: Simple description of the action performed on the application to get some expected output from this action.
Expected Result: It is the expected output from the system or application for the action performed on it.
E.g. For the test case in example, below could be the complete test case structure when we put all together
