Unit Testing Template For Etl Process

Posted on by admin

I keep getting several requests to share a good Test Case Template. And I’m surprised that many testers are still documenting test cases with Word docs or Excel files. Most of them prefer excel spreadsheets because they can easily group test cases by test types and most importantly they can easily get test metrics with the Excel formulas.

But I’m sure that as the volume of your tests goes on increasing, you will find it extremely difficult to manage. If you are not using any test case management tool, then I would strongly recommend using an open source tool to manage and execute your test cases. Test case formats vary from one organization to another. But using a standard test case format for writing test cases is one step closer to setting up testing process on your project. It also minimizes done without proper test case documentation. But even if you use standard templates you need to set up test cases writing, review and approval, test execution and most importantly test report preparation process, all by using manual methods.

Also if you have a process to review test cases by the business team, then you must format these test cases in a template agreed by both the parties. Here is how to make this manual test case management process a bit easier with the help of. Note: I’ve listed maximum fields related to a test case.

But it is advised to use only those fields which are used by your team. Also if you think any field used by your team is missing from this list, then feel free to add it to your customized template. Below are the Standard Fields of a Sample Test Case Template There are certain standard fields to be considered while preparing a Test case template. Several standard fields of a sample Test Case template are listed below. Test case ID: Unique ID is required for each test case. Follow some convention to indicate types of the test. ‘TCUI1’ indicating ‘user interface test case #1’.

Test priority (Low/Medium/High): This is very useful while test execution. Test priority for business rules and functional test cases can be medium or higher whereas minor user interface cases can be of low priority. Test priority should always be set by the reviewer. Module Name: Mention the name of the main module or the sub-module. Test Designed By Name of the Tester Test Designed Date: Date when it was written Test Executed By Name of the Tester who executed this test.

To be filled only after test execution. Test Execution Date: Date when the test was executed. Test Title/Name: Test case title. Verify login page with a valid username and password.

Test Summary/Description: Describe test objective in brief. Pre-condition: Any prerequisite that must be fulfilled before execution of this test case. List all the pre-conditions in order to execute this test case successfully. Dependencies: Mention any dependencies on other test cases or test requirement. Test Steps: List all the test execution steps in detail. Write test steps in the order in which they should be executed.

Make sure to provide as many details as you can. Tip – In order to manage a test case efficiently with a lesser number of fields use this field to describe test conditions, test data and user roles for running the test. Test Data: Use of test data as an input for this test case. You can provide different data sets with exact values to be used as an input. Expected Result: What should be the system output after test execution?

Describe the expected result in detail including message/error that should be displayed on the screen. Post-condition: What should be the state of the system after executing this test case? Actual result: Actual test result should be filled after test execution. Describe system behaviour after test execution. Status (Pass/Fail): If actual result is not as per the expected result mark this test as failed. Otherwise, update it as passed. Notes/Comments/Questions: If there are some special conditions to support the above fields, which can’t be described above or if there are any questions related to expected or actual results then mention them here.

Add following fields if necessary: Defect ID/Link: If the test status is failed, then include the link to the defect log or mention the defect number. Test Type/Keywords: This field can be used to classify tests based on test types. E.g., usability, business rules etc. Requirements: Requirements for which this test case is being written for.

Preferably the exact section number of the requirement doc. Attachments/References: This field is useful for complex test scenarios.

To explain test steps or expected result using a Visio diagram as a reference. Provide the link or location to the actual path of the diagram or document. (Yes/No): Whether this test case is automated or not.

Useful to track automation status when test cases are automated. With the help of above fields I’ve prepared a test case example template for your reference: Download Test Case Template with Example – and – Also, refer few more articles on writing effective here and. Use these test writing guidelines and the above template to write and manage test cases effectively on your project. Conclusion Personally, I prefer to use a test case management tool.

You can start with any open source tool. It will be a good addition to your efforts to set up testing process and meanwhile, it will also save a lot of time instead of manually maintaining these documents. Are you an expert in preparing Test cases? Then kindly share few valuable tips with us. Let us know if you have any queries, comments/suggestion about this post.

79 comments ↓ Ketan Shingate thanks for sharing. We will add some of these fields in our template Guest Its a very detailed document mentioning each and every thing. I use to keep my test cases as simple as i can but really i love this format as well.Definitely i will include some of them to my test case document.

But much of the pamphlet drew on a book from 1944 - which Profile reissued, updated as The Unwritten Laws of Business in 2007. In the summer of 2005, Business 2.0 published a cover story on a self-published management pamphlet by the CEO of American aerospace contractor Raytheon. Lauded by chief executives including Jack Welch and Warren Buffett ('one of the best books I've seen') it became a phenomenon, and more than 300,000 people wrote in to ask for a copy. Unwritten laws of business pdf. Filled with sage advice and written in a clear, engaging style, it offers insights on relating to colleagues and outsiders, the laws of character and personality, personal development, and much, much more - all of which has stood the test of time. This hidden gem was first published 60 years ago but was known only to a lucky few until it resurfaced in 2005 - when 300,000 requests were made for a CEO's personalised version.

Can you please share some good open source test management tools as well? Nice article Vijay. Here you can get a most popular free and paid Testing Tools list used in the testing of the software application: varma you can use test link – @ Muzaffar – Here is a list of some good open source test management tools. Remember when it’s open source there are very few choices and many tools have limitations for advance use. You can’t find every solution in one tool. Use these tools and find which is best for your needs. I find TestLink good for small projects.

Features – manage test cases, keywords, requirements, test plan, test case assignments, builds and many more good features. TestLink – It’s a web based tool to manage test cases and requirements. Bugzilla Testopia – It’s and extension to Bugzilla defect tracking tool. TestCube – web based test case management RTH-turbo – One more web based test management tool Testitool – manage test plan and test cases This should be enough for you to get started. I’ll cover more recommendations with details for both open source and commercial test case management tools in a separate post.

SQL Server - Unit and Integration Testing of SSIS Packages By August 2013 Get the Code: I worked on a project where we built extract, transform and load (ETL) processes with more than 150 packages. Many of them contained complex transformations and business logic, thus were not simple “move data from point A to point B” packages.

Making minor changes was not straightforward and results were often unpredictable. To test packages, we used to fill input tables or files with test data, execute the package or task in Microsoft Business Intelligence Development Studio (BIDS), write a SQL query and compare the output produced by the package with what we thought was the correct output.

More often we just ran the whole ETL process on a sample database and just sampled the output data at the end of the process—a time-consuming and unreliable procedure. Unfortunately, this is a common practice among SQL Server Integration Services (SSIS) developers. Even more challenging is to determine what effects the execution of one package has on subsequent packages. As you build your ETL process, you create a network of connected packages and different resources. It’s difficult to maintain a complete overview of the numerous dependencies among all of these at all times. This article explains how to perform unit and integration testing of SSIS packages by introducing a library called SSISTester, which is built on top of the managed SSIS API.

After reading this article you should be able to use the described techniques and tools to automate unit and integration testing of your existing and new SSIS projects. To understand the article, you should have previous experience with SSIS and C#. SSISTester When I started thinking about a testing framework for SSIS packages, I found three aspects to be important. First, I wanted to have a similar UX to writing tests using the Visual Studio testing framework, so the typical methodology involving setup, verification and cleanup (aka teardown) steps had to be applied. Second, I wanted to use existing and proven tools to write, execute and manage tests.

Once again, Visual Studio was the obvious choice. And third, I wanted to be able to code tests in C#. With that in mind I wrote SSISTester, a.NET library that sits on top of the SSIS runtime and exposes an API that allows you to write and execute tests for SSIS packages. The main logical components of the library are depicted in Figure1. Figure 1 Logical Components of the SSISTester Library The Package Repository is used to store raw XML representations of target packages. Each time a test is executed, a new instance of the Microsoft.SqlServer.Dts.Runtime.Package class is deserialized from XML with all fields and properties set to their default values. This is important because you don’t want different tests that target the same package to accidently reuse any of the values set by previous tests.

Instances of test classes are stored within the Test Repository. These classes contain methods that implement your test cases. When a test is executed, these methods are called by the Test Engine. The specific rules that must be followed when creating test classes will be described in detail later.

Metadata contains the attributes needed to decorate a test class so it can be recognized as a test implementation. The Test Engine looks for these attributes when loading tests into the Test Repository. The Test Context represents a set of classes that provide access to the runtime information during different phases of the test execution. For example, you can use these classes to access different aspects of a package being tested, such as variables, properties, preceding constraints, connection managers, currently executing task, package errors and so forth. The Test Engine refers to the core classes and interfaces of the SSISTester API that directly utilize the managed SSIS runtime.

They are used to load packages and test classes into their respective repositories, as well as to execute tests and to create test results. Mini ETL To create packages and test classes, I’ll use Visual Studio 2012 and SQL Server 2012, and I’ll use three packages to illustrate a simple ETL scenario in which customer data, delivered as a text file, is transformed and stored within a database.

Unit Testing Template For Etl Processes

The packages are CopyCustomers.dtsx, LoadCustomers.dtsx and Main.dtsx. CopyCustomers.dtsx copies the Customers.txt file from one location to another and on the way it converts all customer names to uppercase text. Customers.txt is a simple CSV file that contains ids and names of customers, like so. CREATE DATABASE Demo GO USE Demo GO CREATE TABLE dbo.CustomersStaging( Id int NULL, Name nvarchar(255) NULL ) ON PRIMARY GO The package Main.dtsx contains two Execute Package tasks that execute the sub-packages CopyCustomers.dtsx and Load­Customers.dtsx, respectively. Connection managers in both CopyCustomers.dtsx and LoadCustomers.dtsx are configured using expressions and package variables.

The same package variables are retrieved from the parent package configuration when executed from within another package. Creating Unit Tests To begin, create a console project and add assembly references to SSIS.Test.dll and SSIS.Test.Report.dll. I’m going to create a unit test for the CopyCustomers.dtsx package first. Figure 2 shows the control flow (left) and data flow (right) for CopyCustomers.dtsx.

Figure 3 Control Flow (Left) and Data Flow (Right) of the LoadCustomers.dtsx Package When a test targets a specific task, only that task is executed by the Test Engine. If the successful execution of the target task depends on the execution of preceding tasks, the results of executing those tasks need to be manually generated. The DFT Load Customers data flow expects the target table to be truncated by the SQL Truncate CustomersStaging task. Further, the data flow expects the transformed Customers.txt file at a specific location.

Because this file is created by the CopyCustomers.dtsx package, I need to copy it manually. Here’s the Setup method that does all this. Creating Integration Tests The basic idea of unit tests is to isolate all of the possible effects other packages or tasks may have on the one being tested. Sometimes it can be challenging to create a realistic test setup and the initial conditions needed for a unit test to ensure the package or task being tested behaves like a part of a complete ETL process. Because you usually implement ETL processes with a number of packages, you need to perform integration tests to be sure that each package works well when run as part of that process. The idea is to define probing points in your ETL process where you want to perform tests, without having to stop the whole process. As the process progresses and reaches the probing point, your tests are executed and you can verify a “live” work-in-progress ETL process; hence the name, “live test.” A live test is basically a post-condition—defined for a package, task or event handler—that needs to be satisfied after the package, task or event handler has executed.

Unit

This post-condition corresponds to the verification step of a unit test. Live tests are different from the unit tests because it’s not possible to prepare the test prior to package execution or to perform a clean-up step afterward. This is because unlike a unit test, a live test doesn’t execute the package; it’s the other way round: A package executes a test when it comes to the probing point for which a post-condition is defined. Figure 7 illustrates this difference. Note the position of the package in both figures.

When running unit tests, the Test Engine explicitly executes a unit test by calling its Setup, Verify and Teardown methods. A package is executed as a part of this Setup-Verify-Teardown sequence.
