Combine automated tests with a data from an Excel spreadsheet, CSV file, or SQL database to test faster and more accurately.
Data-driven testing separates test procedures from test data, to increase efficiency and reduce maintenance.
An automated test consists of two parts: the procedure, which is a set of steps to perform; and the data to use in the test. For example, a test for a login dialog would include steps to open the application, enter the username, enter the password, click the Submit button, and check that the application responded correctly. The data for this test would include a username, password, and the expected results of the test, such as a successful login or an appropriate error message.
Typically, a login test would be repeated for multiple combinations of valid and invalid username and passwords. In data-driven testing, the test data is stored in a table separate from the test procedure. During a test run, the test procedure is performed once for each row in the data table. Thus, the data in the table can be said to “drive” the execution of the test.
Build automated test cases and connect them to a data source with a data-driven testing framework.
With a data-driven testing framework, you can create an automated test and connect it to a data source using one or more variables. In the example of a login process, the username, password, and expected result can all be configured as variables. When the test executes, the variables are replaced by values from the data source. In Ranorex Studio, your data source could be a simple internal table, a CSV file, a Microsoft Excel spreadsheet, or a SQL database connector. Using the SQL database connector, you could execute your automated tests against a test database, or even your full production database.
Instead of redundant test cases that each check a particular set of data values, with data-driven testing, you have just a single test case to maintain. Easily add or remove scenarios by changing the test data without affecting the test procedure.
A data-driven automated testing framework can execute a large volume of tests far more rapidly than manual testing, especially for repetitive test cases that cover positive and negative test data values, or corner, edge, and boundary cases.
Automated data-driven test cases can execute during off-hours, when test machines would otherwise be idle. With manual testers freed from entering repetitive test data, they can focus on more challenging exploratory and user experience testing.
In addition to functional testing, you can use data-driven procedures to simulate data entry for load and performance testing. It’s also possible to use a data-driven test case to populate a test or even a production database.
Mastering Data-Driven Testing with Ranorex Studio: Maximize the benefit of your test cases by linking them to data sources such as spreadsheets or SQL databases.
Improve test efficiency and coverage with Ranorex Studio test automation features.
You aren’t limited to CSV files for your data-driven testing. Ranorex Studio also supports simple internal data tables, Microsoft Excel spreadsheets, and SQL database connectors. Use a single source or combine sources for maximum flexibility.
Rapidly build tests with tools for codeless automation, or use the full IDE. Ranorex Studio automatically identifies UI elements and stores them as objects in an object repository. In addition to input fields, the repository enables data-driven testing for controls such as radio buttons and checkboxes.
Editing a test procedure is easy with the Ranorex Studio action editor. Use drop-down menus make to create variables that connect repository objects to your data source(s). Point and click to manually bind test variables to input values, or allow the auto-bind function to do it for you.
Validations are essential to verify the correct functionality of your application. Easily build complex data-driven validations while recording tests. Compare images as well as text, all without writing a single line of code. Mask input and validation values as desired, to keep them from appearing in the test report.
Accelerate testing and increase productivity by running your tests in parallel using a Ranorex Agent. Or, use the built-in Selenium WebDriver integration to distribute tests on a Selenium Grid, either locally or in the cloud. Beginning with Release 8.3, save even more time with our installation-free remote test execution.
Manage the behavior of automated tests with conditions. Each condition can include up to 10 rules to manage decisions such as whether to perform a test based on the current data value. If a test fails, a rule can control whether to continue with the next data value, jump to the next test case, or stop the test run.
Built-in support for data-driven testing in Ranorex Studio simplifies data-driven cross-browser and cross-platform testing
Designing a Selenium WebDriver framework for data-driven testing is technically challenging, and that doesn’t include the effort necessary to automate and execute tests.
Increase your efficiency by using Ranorex Studio to easily configure data-driven testing for a web application in a single browser. Define a variable for the browser, and you can use a data table to drive your cross-browser testing. Ranorex Studio’s built-in Selenium WebDriver integration allows you to execute your automated tests on all Selenium-supported platforms and browsers, including Linux and macOS. Then, save even more time by executing your cross-browser tests in parallel. Simply use the Ranorex Parallel Runner to execute your test suite across multiple capability sets on a Selenium Grid through a WebDriver endpoint in parallel.
