This type of testing category involves matching the count of data records in both the source and target systems. This type of testing category involves data validation between the source and the target systems. Here it helps to perform data integration and threshold data value check and also eliminate the duplicate data value in the target system.
This type of testing category confirms the data mapping of any object in both the source and target systems. This also involves checking the functionality of data in the target system. This involves the generation of data reports for end-users to verify if the available data in the reports as per your requirements. With the help of this testing, you can also find the deviations in the report and cross-checks the data in the target system to validate the report.
It involves fixing the bugs and defects in the data in the target system and running the data reports to perform data validation. This involves testing all the individual source systems and then combines the results to find if there are any deviations. There are three main approaches available here:. ETL testing can also be divided into the following categories:.
In this type of ETL testing, your new data warehouse system can be built and verify the data. Here the input data can be taken from end-users or customers forms the different data sources then a new data warehouse is created. In this type of testing, customers will have an existing data warehouse and ETL tool, but here they look for a new ETL tool to improve the data efficiency.
This testing involves data migration from the existing system by using a new ETL tool. In this change testing, new data will be added from the different data sources to an existing system. Here customers can also change the existing ETL rules or new rules can also be added. In this type of testing, the user can create reports to perform data validations.
Here the reports are the final output of any data warehouse system. Report testing can be done on the basis of layouts, data reports, and calculated values.
Ab Initio ETL testing techniques play a vital role and you need to apply these techniques before performing the actual testing process. These testing techniques should be applied by the testing team and they must be aware of these techniques. There are various types of testing techniques available, they are:. This type of testing technique is used to perform analytical data reporting and analysis function, and also checks for the validation data production in the system.
The production validation testing can be done on the data that is moved to the production system. This technique is considered to be a crucial testing step as it involves a data validation method and compares these data with the source system. This type of testing can be performed when the test team has less to perform any type of testing operations.
The targeted testing checks the data count in the source as well as target systems. In this type of testing, a test team involves invalidating the data values from the source system to the target system. This checks the corresponding data values also available in the target system. This type of testing technique is also time-consuming and mainly used to work on banking projects. In this type of testing, a test team will validate the data ranges.
All the threshold data values in the target system will be checked if they are expecting the valid output. With the help of this technique, you can also perform data integration in the target system where data is available from the multiple data source system once you finish the data transmission and loading operations. Application migration testing is normally performed when you move from an old application to a new application system.
This type of testing saves a lot of your time and also helps in data extraction from legacy systems to a new application system. This testing includes the various types of checks such as data type check, index check, and data length check. This testing technique involves checking for the duplicate data situated in the target system.
When there is a huge amount of data residing in the target system. It is also possible that there are also duplicate data available in the production system. The following SQL statement used to perform this type of testing technique:. Duplicate data appears in the target system because of these reasons:.
If no primary key is specified, then the duplicate values may come. This also arises due to incorrect mapping and environmental data issues. Manual errors arise while transferring data from the source system to the target system.
The data transformation testing is not performed by using any single SQL statement. This testing technique is time-consuming and also helps to run multiple SQL queries to check for the transformation rules. Here the testing team needs to run the SQL statement queries and then compare the output. This type of testing includes operations like number check, date check, null number check, and precision check, etc.
Here the testing team also performs syntax tests to check any invalid characters and incorrect upper or lower case order. Reference tests also are done to check if the data is available according to the data model. Incremental testing can be performed to verify if the data insert and update the SQL statements. These SQL statements are executed as per the expected results. This testing technique is performed step by step with old and new data values. When you make changes to any data transformation and data aggregation rules used to add new functionality.
This also helps the testing team to find a new error is called regression testing. The bug also comes in regression testing and this process is known as regression. When the test team runs the tests after fixing any bugs is called retesting.
System integration testing includes the testing of system components and also integrates the modules. There are three ways of system integration available such as top-down, bottom-up approach, and hybrid method. Navigation testing is also called front-end system testing. This involves the end-user point of view testing can be performed by checking all the aspects such as various fields, aggregation, and calculations. This Ab Initio testing involves ETL lifecycles, and also helps to a better understanding of the business requirements.
Test estimation step is used to provide the estimated time to run the test cases and also completes the test summary process report. Test planning methods involve finding the testing techniques based on the data inputs as per the business requirements. Once the test cases are ready to perform testing and approved, the next step is to perform any pre-execution check.
The last and final step to create a complete test summary report and file a closure test process. This type of approach makes ETL testing is very low, time-consuming, and error-prone.
Query surge is nothing but a data testing solution that is designed to perform big data testing, data warehouse testing, and the ETL process. This process can automate the entire test process and fit nicely into your DevOps strategy.
It consists of query wizards to generate test Query pairs fast and easily without having to write your SQL statements. ETL processes debugging and monitoring. Ab initio extensions are provided to the operating system. Graphical Development Environment : This component helps developers in running and designing abinitio graphs.
Ab initio graphs represent ETL process in ab initio and are formed by components, data streams flow and parameter. This provides an easy to use front-end application for designing ETL graphs. It facilitates to run and debug ab initio jobs. It traces execution logs. Enterprise Meta Environment EME : This is an ab initio environment and repository used for storing and managing metadata. It has the capability to store both technical and business metadata.
Conduct IT: This is an environment used for creating ab initio data integration systems. The prima focus of this environment is to create special type of graphs called ab initio plans. Ab initio provides both command-line and graphical interface to Conduct IT. Data Profiler: This runs on top of co-operating system in graphic environment This is an analytical application which can determine data range, quality, distribution, variance and scope.
If ab initio have been just an ETL tool, it might have been out of the race or may be cornered because of its price tag. Some fifty odd companies from fortune list use Ab initio as it is expensive and may not be prefered by small or medium sized corporations.
