All of this affects how the unit test will behave since this is the data being used for unit test execution.
As such, this part of unit testing is the most time consuming as it requires some understanding of the code you are testing to know what data to use for testing. Keep it simple by using just the parts needed for the code being tested. Mocks are very useful in this phase as they allow you to control how methods from those objects will behave when interacting with your test. We do not want to introduce nor configure another object for this test as it adds another layer of maintainability for that object, and it is not affecting the result of the method under test.
The next line shows the Account object being created along with the mock and the Initial Balance to prepare the method we are testing for with the data we just used. The next line defines the input as the method under test requires a number to be used.
Then the method is executed with the result of the method being stored in our variable for us to use later. Once the test can complete successfully as in it runs from start to finish with no exceptions or errors , then it is time to apply an assertion to the unit test.
Without the assertion, the unit test is meaningless since there is nothing you are enforcing to ensure it is working as intended. Collecting coverage of what lines were executed does tell what was executed but it does not provide enough detail to determine the following:.
As long as the unit test contains one assertion that is checking the method under test result, this is a meaningful unit test. How to write effective tests and test cases can be streamlined over time. Some best practices include using strong titles, strong descriptions, and keeping the language concise and clear.
The other aspect of a test case involves test suites and test plans. These differ in key ways and both are vital to accurate test case development. A test suite comes into play for test cases as it relates to source code, the collection of dependencies, or the suite of tests to be performed on code. Test suites allow you to categorize test cases in ways that align with any analysis or planning needs.
This means that core software features might have their own test suite while another test suite is for a specific testing type such as smoke or security. Think of test suites as a bookshelf to organize your test cases on. In contrast, a test plan is more like the umbrella that stands over all of the test suites. If test cases are books and test suites are bookshelves, then test plans are the room that contains the bookshelf. Generally, test plans are set up in terms of manual tests, automated tests, and a general format of how to go about testing.
Step 5 That apart your test case -may have a field like, Pre — Condition which specifies things that must be in place before the test can run. For our test case, a pre-condition would be to have a browser installed to have access to the site under test. A test case may also include Post — Conditions which specifies anything that applies after the test case completes. This entire table may be created in Word, Excel or any other Test management tool.
Create test cases that are as simple as possible. They must be clear and concise as the author of the test case may not execute them. Use assertive language like go to the home page, enter data, click on this and so on. This makes the understanding the test steps easy and tests execution faster.
The ultimate goal of any software project is to create test cases that meet customer requirements and is easy to use and operate. A tester must create test cases keeping in mind the end user perspective. Do not repeat test cases. If a test case is needed for executing some other test case, call the test case by its test case id in the pre-condition column.
Do not assume functionality and features of your software application while preparing test case. Stick to the Specification Documents. A submit button on a contact form, for example, is only activated after the end-user has completed all of the required fields. The tester can use this approach to test the behavior of an AUT. This action can be carried out by the tester by sequentially entering various input circumstances.
The testing team uses the state transition approach to evaluate the system's behavior by providing both positive and negative input test values. When a testing team is evaluating an application for a limited set of input values, state transition should be employed. When the testing team wishes to test a sequence of events that occur in the application under test, this approach should be employed.
In the following example, the user will be able to log in successfully if he or she provides a correct password in any of the first three attempts.
The user will be requested to re-enter the password if the user enters an incorrect password on the first or second attempt. When a user incorrectly enters their password for the third time, the action is taken, and the account is blocked.
The structure-based or white-box approach creates test cases based on the software's underlying structure. This method thoroughly checks the code that has been produced. Developers with a thorough understanding of the software code, its internal structure, and design assist in the creation of test cases.
There are five different types of this approach. This method entails running all of the source code's executable statements at least once. According to the specified requirement, the proportion of executable statements is determined. For checking test coverage, this is the least desired statistic.
This approach, also known as branch coverage, is a testing method that ensures all reachable code is run by executing each of the potential branches from each decision point at least once. This aids in invalidating all of the code's branches.
List all the preconditions to execute the test case successfully. For example: sign up in the system. If there are no preconditions, the field stays unfilled. Dependencies : Mention any dependencies must be mentioned in other test cases or test requirement. Expected Result : What is the system output after the test execution? Actual result : Actual test result may be filled after test execution. Describe system behavior after test execution. Test Steps : List all test execution steps in detail.
Write test steps in the order providing all the possible information in which these should be executed. Tip - to efficiently manage test case with lesser number of fields use this field to describe test conditions, test data, and user roles for running test. If test status is abandoned, then include the link to defect issue or mention the issue number.
Otherwise, update as passed. Requirements : Requirements, for which this test case is written. Preferably the exact section number of the requirement doc. To explain test steps or expected result using an attached file. Provide the link or location to the actual path of the attached file. Post conditions : E. Manual Test Cases Writing Hacks.
