  1. ETL Testing – Techniques It is necessary that you just outline the right ETL Testing technique before beginning the testing method. You must take associate degree acceptance from all the stakeholders and make sure that an accurate technique is chosen to perform ETL testing. This method ought to be best-known to the testing team and that they ought to bear in mind of the steps concerned within the testing method. Production Validation Testing To perform Analytical reportage and Analysis, the info in your production ought to be correct. This testing is completed on the info that's stirred to the assembly system. It involves information validation within the production system and examination it the with the supply information. Source-to-target Count Testing This type of testing is completed once the tester has less time to perform the testing operation. It involves checking the count of information within the supply and also the target systems. It doesn’t involve checking the values of information within the target

  2. system. It additionally doesn’t involve if the info is in ascending or raining order when mapping of information. Source-to-target information Testing In this sort of testing, a tester validates information values from the supply to the target system. It checks the info values within the supply system and also the corresponding values within the target system when transformation. This sort of testing is long and is generally performed in money and banking comes. Data Integration / Threshold price Validation Testing In this sort of testing, a tester validates the vary of information. All the brink values within the target system area unit checked if they're as per the expected result. It additionally involves integration of information within the target system from multiple supply systems when transformation and loading. Application Migration Testing Application migration testing is generally performed mechanically once you move from associate degree recent application to a replacement application system. This testing saves plenty of your time. It checks if the info extracted from associate degree recent application is same as per the info within the new application system. Data Check and Constraint Testing It includes acting varied checks like information sort check, information length check, and index check. Here a take a look at Engineer performs the subsequent eventualities − Primary Key, Foreign Key, NOT NULL, NULL, and UNIQUE. Duplicate information Check Testing This testing involves checking for duplicate information within the target system. Once there's an enormous quantity of information within the target system, it's doable that there's duplicate information within the production system which will end in incorrect information in Analytical Reports. Data Transformation Testing Data transformation testing isn't performed by running one SQL statement. It long and involves running multiple SQL queries for every row to verify the transformation rules. The

  3. tester has to run SQL queries for every row so compare the output with the target information. Data Quality Testing Data quality testing involves acting range check, date check, null check, exactitude check, etc. A tester performs Syntax take a look at to report invalid characters, incorrect upper/lower case order, etc. and Reference Tests to visualize if the info is in keeping with the info model. Incremental Testing Incremental testing is performed to verify if Insert and Update statements area unit dead as per the expected result. This testing is performed in small stages with recent and new information. Regression Testing When we create changes to information transformation and aggregation rules to feature new practicality that additionally helps the tester to search out new errors, it's known as Regression Testing. The bugs in information that that comes in regression testing area unit known as Regression. Retesting When you run the tests when fixing the codes, it's known as retesting. System Integration Testing System integration testing involves testing the elements of a system separately and later integration the modules. There are a unit 3 was a system integration will be done: top- down, bottom-up, and hybrid. Navigation Testing Navigation testing is additionally called testing the front-end of the system. It involves end- user purpose of read testing by checking all the aspects of the front-end report – includes information in varied fields, calculation and aggregates, etc.
