![]() ![]() Includes 70 built-in functions and an expression processor to define complex test data with dependencies, relationships, and internal structure.Offers 15 methods to fill in fields with random and repeatable data models.Supports IBM DB2, MySQL, Firebird, Oracle and Microsoft SQL server.Use cases include test database population, performance analyzing, QA testing, and loading tests fulfillment. It automatically creates data values or schema objects such as views, procedures, tables, and triggers. Provides self-service forms to find, view, analyze, and observe test data.ĭTM Data Generator produces data for high-quality and realistic test arrays.Centrally stores data as a reusable asset.Performs PII audits to ensure compliance to industry regulations.Generates synthetic test data to increase test data coverage.Provides secure masked test data to application teams.Can build a data model from heterogeneous data sources and scan for PII.Has the highest practitioner rating in the Gartner Peer Insight for test data masking solutions.Rated as the top champion by the recent Bloor Research report.Some organizations have reported a 90-95 percent reduction in the time taken to provision high-quality test data. Organizations can use Test Data Manager to find and match data to the specific tests it can run, then provision the data automatically on-demand and in parallel. Test Data Manager can also enhance the quality of production data by filling gaps in test data coverage, thus creating all the data needed to cover continuous testing requirements. This helps optimize test cycles so DevOps teams can deliver applications faster. Here are our top picks for test generator tools:īroadcom’s Test Data Manager tool provides the capability to quickly locate, secure, design, create, and provision ‘fit for purpose’ test data. DevOps turns to these tools when no existing data is available. That’s where test data generator tools come into play-they help developers create sensible data sets that mirror realistic data. ![]() But for brand new applications, no such data exists yet. ![]() For example, if developers are working on an update to an existing application, there may be a wealth of data they can use to test the features of the new version. In some cases, there may already be real data available for testing. Testing the application with realistic data makes the development process more robust and helps developers catch errors that could come back to haunt them once the app is in production. Developers need to ensure they are testing their applications under conditions that closely approximate actual production environments.įor example, a DevOps team would want to simulate a high volume of users performing a variety of actions to ensure the application will be able to sustain such traffic. What is test data?Īs the name implies, test data is data that DevOps teams use to test their applications in development. But which is best? There answer depends on the unique needs of your business and DevOps team. They generate sample test data that is utilized in executing test cases. Thanks for watching.Test data generation tools are critical to the success of your software project. I leave the task of actually inserting these fancier emails into our table as an exercise for the viewer. This of course gets concatenated into the rest of the email string. The case statement then produces one of the three host names based on that random number. selectĪs each row from the generate_series is processed, we will get a new random number from 0 to 2. How about some random email host names? We can do this with a little more string concatenation and a case statement nested in a subquery. We can even take this all a bit further by adding some variation. We can run the table command to see that everything was inserted as expected. Select 'person' || num || generate_series(1,10000) as num For this we can use an insert statement with a select clause. The next step is to insert them into our users table. select 'person' || num || generate_series(1,10000) as num We can do that with some string concatenation. Now we need a way to turn those integers into emails. The generate_series() function will help us with that. However, what if we need a lot of records, like 10,000 records? If we just need 2 or 3 records, then writing a couple insert statements should suffice. We will work with a users table that has an email address field. In this episode, we will see how we can quickly generate a bunch of fake emails with nothing more than a fancy Postgres statement. Perhaps you want to compare the relative performance of various queries or maybe you need a big table to try out that new Postgres feature. Sometimes you just need a bunch of fake data. ![]()
