In this definition, a test case is comprised of a test condition, an expected result, and a procedure for performing the test case. I like this definition because it implies that test cases can be performed either in combination with other test cases or in isolation.
This is an important distinction when testing web interfaces, which allow a user to perform actions in a random and unpredictable manner.
Modular test cases are like objects which can be performed in isolation but often have the requirement of interfacing with other test cases to achieve a particular objective. The important concept to remember is that the sequence of performing test cases may be unpredictable from the test designer's perspective, but can be critical in manifesting a defect.
Test Scripts. When deciding to use test cases vs. Much depends on how much time you have, your prior knowledge of what you're viewing and the freedom you would like to have during the experience. Likewise, in the decision of using test scripts vs.
The decision to use test cases versus test scripts depends on:. The main benefit of a test script is that it predefines a procedure to follow in performing a test. This can also be its greatest curse. Sometimes you want the randomness of user actions. At the same time, you want to know in advance the conditions to be tested and how they should behave.
This is the classic tradeoff between test scripts and test cases. Just because you choose to use a test script in testing one area of your application does not imply you must use test scripts for testing everything in an application. You may choose to only create test scripts for the definable processes that are critical and that apply well to scripting.
For everything else you could decide to use test cases. The Sources of Web Test Cases. Many web testers describe the process of testing web applications as trying to hit a moving target. Just when you think you have things in place, they change. In fluid development environments like the web, software development happens quickly and functionality can change just a quickly. Before we can define a test case, we need to know how the web application is intended to behave.
There are many sources of test cases in a typical web application and I will examine the ones that give you the best results with the least amount of effort in test case design and execution.
Web Test Case Components. The structure of test cases is one of the things that stays remarkably the same regardless of the technology being tested. The conditions to be tested may differ greatly from one technology to the next, but you still need to know three basic things about what you plan to test:.
ID : This is a unique identifier for the test case. The identifier does not imply a sequential order of test execution in most cases. The test case ID can also be intelligent. For example, the test case ID of ORD could indicate a test case for the ordering process on the first web page.
Condition: This is an event that should produce an observable result. For example, in an e-commerce application, if the user selects an overnight shipping option, the correct charge should be added to the total of the transaction.
A test designer would want to test all shipping options, with each option giving a different amount added to the transaction total. Expected Result: This is the observable result from invoking a test condition.
In the previous example of an e-commerce shipping option, the expected results would be specifically defined according to the type of shipping the user selects. Procedure: This is the process a tester needs to perform to invoke the condition and observe the results. A test case procedure should be limited to the steps needed to perform a single test case. For the purpose of space, I typically use the same column to indicate both "pass" P and "fail" F. In some situations, such as the regulated environment, simply indicating pass or fail is not enough information about the outcome of a test case to provide adequate documentation.
For this reason, some people choose to also add a column for "Observed Results. You can specify configurations, such as different operating systems, web browsers, and other variations for your tests. To assign test configurations to all test cases in a test suite, select the test suite, select More options or right-click to open the context menu, and then select Assign configurations.
In the Assign configurations to test suite dialog box, select the configurations you want. You can also assign configurations to individual test cases. Select one or more test cases, select More options or right-click to open the context menu, and then select Assign configuration. The Assign configurations to selected test cases dialog box opens.
Make and save your changes. For more information about configurations, see Test different configurations. You can reorder manual test cases in static suites, requirement-based suites, and query-based suites. Open a test case, then use the up and down arrows to change the order. Select a test suite.
From the New Test Case menu, select Add existing test case. In the Add test cases to suite dialog box, add search clauses, as needed, and then select Run query. To create test cases this way, open the shortcut menu for the work item and choose Add test.
Choose the Click or type here to add a step link and add test steps with a description of the action required to carry out the test and the expected results so that any team member can run the test. Now you've created a test case that you can run. How can I find an existing test case within a test plan? Choose Order tests on the tool bar, then drag and drop one or more tests. Or open the shortcut menu for a test to move it to the top or to another position.
After reordering the tests, you can sort them by the Order field and then run them in that order with the web runner. To learn more, see Add, run, and update inline tests. Instead, you can select several test cases and open them for editing in the Grid view. In the context menu, select Edit test case s in grid. You can edit other fields in the Grid view. In the List view, use the column options to select the fields in the test case work item.
Switch between Grid and List views using the View menu at the right of the window. Do not use the Teams plugin for Excel to add or update test case work items. Excel cannot parse the format used to store test steps, and in some cases this may affect the formatting of the test case work items.
You can copy test cases and test steps from an existing Excel worksheet. Copy the columns from Excel that you want to use for the title, action, and expected results fields. Copying does not copy column formatting, other than multiline, from the worksheet.
Paste these columns into the Grid view, edit if necessary, and save them. You can copy the data from the Grid view and paste it into your Excel worksheet. Copying does not copy test step formatting, other than multiline, into the worksheet. This is supported only with Internet Explorer and Chrome browsers.
You can reassign test cases so that a different tester can run them. Script enhancement helps to add some custom logic, basic parameters and dynamic value handling functions etc. The script enhancement covers the following steps:. Once the script enhancement is done then the script needs to be replayed to ensure whether the script is working fine or not. If the error comes at any step or script does not perform as per the business flow then it requires debugging. In most of the cases, dynamic value correlation is the primary cause of script failure.
In some cases, the script runs successfully without any error but data is not updated in the backend like a product not submitted, order not placed, DB data not modified etc. Hence it is recommended to verify the result in the backend as well.
Once the performance tester completes the scripting work, it must be verified by a performance test lead. The main deliverable of this phase is runnable Performance Test script for all the business scenarios defined in the performance test plan. Where is PerfMate? Now, he will help to understand the performance test scripting phase practically:. PerfMate needs to create 7 scripts which are finalized in the test planning phase.
PerfMate assigns this work to 2 performance testers of his team. Firstly, he provides knowledge of the scenarios to them and then performance testers start to prepare the scripts. They record and enhance the script using a Performance Testing tool. Like this, they saved the time and completed the scripting work without any delay. After getting the performance test environment, they validate all the scripts as well as test data.
Now, all the performance test scripts are in ready to test state:. PTLC Scripting. Your email address will not be published. Save my name, email, and website in this browser for the next time I comment. Performance Test Scripting. Performance Testing Life Cycle. What is a Performance Test Script?
Purpose of Performance Test Script: The main purpose of the performance test script is to simulate the behaviour of a real-world user. Accountability: Performance Test Analyst or Engineer designation may vary as per company policy develops the test scripts after getting a detailed understanding of Performance Test Scenarios from Performance Test Plan. Approach: A performance tester needs to read-out the Performance Test Plan before going to start the scripting work.
Scripting in the Performance Test environment: If the performance test environment is ready then it is a good practice to use it for scripting purpose. Scripting in other than Performance Test environment: It is a generic scenario to provide another development or functional testing environment to create the performance test script.
If you like to create test script using this method, you will typically still have the ability to record or playback and generate a simple script. It is important to understand that you can choose your programming language even if your application is written in Java.
However, it does not mean that you need to write your test scripts in Java, which can be difficult to learn. Instead, you can write your test scripts in an easier language like JavaScript or Ruby or any easier language you wish to use. Your test script should be clear. If the tester need to constantly ask the project in-charge person to give details about the application.
This certainly wastes time and resources. To avoid this , you need to constantly verify that each step in the test script is clear, concise, and coherent. This helps to keep the testing process smooth. You should create a test script that should contain just one specific action for testers to take.
