Integration Testing Four step procedure. As I wrote in my previous posts, Integration testing is designed to test the structure and the architecture of the software and determine whether all software components interface properly. Integration testing does not verify that the system is functionally correct, only that it performs as designed. Interesting readers question How is testing carried out in a company i. Here is the actual testing process of Software Testing in the. It is the process of identifying errors introduced by combining individual program unit tested modules. Integration Testing should not begin until all units are known to perform according to the unit specifications. It can start with testing several logical units or can incorporate all units in a single integration test. Below are the four steps of creating integration test cases Step 1 Identify Unit Interfaces The developer of each program unit identifies and documents the units interfaces for the following unit operations Responding to queries from terminals for information Managing transaction data entered for processing Obtaining, updating, or creating transactions on computer files Passing or receiving information from other logical processing units Sending messages to terminals Providing the results of processing to some output device or unit. Step 2 Reconcile Interfaces for Completeness The information needed for the integration test template is collected for all program units in the software being tested. Whenever one unit interfaces with another, those interfaces are reconciled. For example, if program unit A transmits data to program unit B, program unit B should indicate that it has received that input from program unit A. Interfaces not reconciled are examined before integration tests are executed. Step 3 Create Integration Test Conditions One or more test conditions are prepared for integrating each program unit. After the condition is created, the number of the test condition is documented in the test template. Idm Manager With Crack. Step 4 Evaluate the Completeness of Integration Test Conditions The following list of questions will help guide evaluation of the completeness of integration test conditions recorded on the integration testing template. This list can also help determine whether test conditions created for the integration process are complete. Q1. Is an integration test developed for each of the following external inquiries Record test File test Search test Matchmerge test Attributes test Stress test Control testQ2. Are all interfaces between modules validated so that the output of one is recorded as input to another Q3. If file test transactions are developed, do the modules interface with all those indicated files Q4. Is the processing of each unit validated before integration testing Q5. Do all unit developers agree that integration test conditions are adequate to test each units interfacesUnit Testing Template For Etl Process PptUnit Testing Template For Etl Process ExampleIntegration Testing Four step procedure Below are the four steps of creating integration test cases. Q6. Are all software units included in integration testing Q7. Are all files used by the software being tested included in integration testing Q8. Are all business transactions associated with the software being tested included in integration testing Q9. Are all terminal functions incorporated in the software being tested included in integration testingETL Testing Data Warehousing Testing. In previous article we learned about What Is Difference Between SDET And TESTER In todays class we are going to cover What is importance of ETL testing and Data Warehousing, importance, testing classifications, testing procedures etc. Introduction on ETL Testing ETL stands for Extraction, Transformation and Loading of data. In data warehousing, data from multiple data sources is extracted, transformed as per the business logic and data definition of target database and loaded into cohesive database. Data warehouse efficiently handles day to day data along with organizations historic data which may be very useful in creating reports for audits and compliances, future market predictions, etc. Since data loaded is very critical to the organization therefore it is very important for ETL process to undergo testing whether the extraction and transformation logic of data is as expected and also the loaded data is meaningful and as per requirements. Therefore ETL testing is new testing field for testers to pursue their career and this is the correct time to gain knowledge about ETL and Data warehousing testing. Importance of Data Warehousing As organization businesses are growing day by day which is creating more and more data therefore there is a need to retain data in well organized manner so that it is available for companys day to day business expectations. Unit Testing Template For Etl Process In Data' title='Unit Testing Template For Etl Process In Data' />Thus organizations are required to practice best extraction, transformation and loading technologies to integrate historical, day to day and other business data into centralized target database. In order to achieve this, many companies are creating their own database using various ETL tools to make the process very efficient. ETL tools make the process of extractions from multiple data sources very comprehensive and then transformation is done based on the required business rules. This transformed data is persisted into cohesive database known as Data warehousing and process is known as ETL data warehousing. In order to make sure that the scripts applied in the ETL tools for extraction, business rules for transformation and data loaded are correct, there is a need to prepare the required test plan and test cases. Organizations may gain confidence in their business after Smooth ETL process which can only be achieved by efficient testing of entire ETL process, which is well planned and executed by the team of test experts who are proficient in ETL testing. ETL Testing Classification Irrespective of using ETL tools, ETL testing can be classified into following types New Data warehouse project This scenario involves testing of DW from scratch. Required test plan is created and functional points are identified in ETL functional documents. Accordingly test plans are prepared and executed by ETL testers. Adding new source to existing Data warehouse DW has multiple data sources. Data from these sources is transformed and persisted in cohesive DW database. Adding new data source involves provigil generic 1. DW. Here testing expectations are to feed data from new source that is compatible with existing business rules and DW. Migration of Data warehouse Here underlying database is migrated, for example, say from Oracle to Teradata depending on clients trust on vendor. Here ETL test team is expected to run all the existing test cases and make sure all test pass without any roadblock. Moreover test team conducts the performance test to justify the fact that the migration project has benefits over existing database. Change of Business Logic Sometimes there is the need to change the existing business logic or add new business logic in data transformation. Test team here builds new test cases according to the new logic and make sure that old functionality is not affected by this new change Regression.

Platform Migration Sometimes entire DW is migrated from one machine to another machine, for example, migration of database from low performance to high performance hardware boxes. In such scenario ETL tester are expected to execute existing test cases with additional performance tests to make sure ETL process is not broken and there are no roadblocks for business as usual. ETL Testing procedure Testing procedures for ETL as follows ETL test team is provided with functional requirements documents. Test team does the validations and come up with test estimates. Test planning is started based on above information. Background Army Supply Chain Management Overview. Depot. Supply Support Activity. OEM Factory. Unit. SERVICEABLE. UNSERVICEABLE. Prescribed Load List. Repair Order. In previous article we learned about What Is Difference Between SDET And TESTER In todays class we are going to cover What is importance of ETL testing and. From last couple of days I am getting more request on Sample test plan. So for your reference I am including one sample test plan template here. Its a Index of Test. Manual testing is performed by a human sitting in front of a computer carefully executing the test steps. Automation Testing means using an automation tool to execute.

After test cases are approved by senior member, they are executed by test team till the expected output is obtained. Performance tests are also executed by ETL expert test team. After successful completion of ETL testing, test summary report is prepared and handed over to the senior project team and testing tasks are signed off by ETL test team. Over to you on ETL Testing Data Warehousing Testing Like any other software application testing, ETL testing follows same testing principles and since this ETL testing is the niche skill required in the market therefore such resources are on high demand in the market. ETL testers are expected to have good knowledge of ETL procedures, SDLC, SQL queries and system performance testing. A human resource with all of these skill set is an expert ETL tester.
