# CAT 1.13.0


This release contains small enhancements for CAT Studio.

You don't need to upgrade CAT PowerShell / CAT CLI; there are new features only in CAT Studio.

## Run only selected tests

The most requested feature for the CAT Studio was the ability to run only selected tests. Now it is possible:

![CAT tests, 2 passed, 1 failed, the remaining not executed yet](run-selected-tests.png)

Hold the `Ctrl` key to select more tests, the `Shift` key to select range of tests, or `Ctrl`+`A` to select all visible tests. Then just hit the *Run Selected Tests* button.

Please note the number of passed and failed tests shows the results from the latest run.

## Queries enhancements

In the CAT Studio, you can also run ad hoc queries against your data sources - whether those are CSV files, data in Power BI workspaces, Databricks delta tables or anything else - you can just run your ad hoc queries to troubleshoot your tests.

In this release:

* When an error occurs (such as incorrect syntax), the exception message is visible.

* CAT returns the number of rows returned (for successful queries only)

* You can clearly tell whether your query is still running or has finished already.

* When a query does not return any rows, the grid with column names is displayed regardless.

-----------------------------------------

CAT Studio has our full attention now; you can expect bigger updates in the near future. Please also remember CAT Studio is still in a preview phase and lots of things may change.

That's it :-). Happy testing!
