It is a GUI (graphical user interface) for CAT. It has a built-in AI assistant called CAT Pilot. It looks like this: With CAT Studio, you can test almost any data (all major relational databases, cloud databases, Power BI, Databricks, MS Fabric, Azure Synapse Analytics, and many others), compare data across systems, generate tests from metadata, and much more. https://docs.justcat.it/reference/cat-studio/installation/ Thu, 04 Apr 2024 14:40:56 +0100 https://docs.justcat.it/reference/cat-studio/installation/ There are two options for how to get CAT Studio: Microsoft Store (recommended) Download the installer from our Releases page. Microsoft Store # You can get CAT Studio from Microsoft Store. Open the Microsoft Store from your Start menu: Find “CAT Studio” (don’t search just for CAT, you’d get too many results): Get it like any other application. The big advantage of having CAT Studio from Microsoft Store is that you’ll also get any updates automatically. https://docs.justcat.it/reference/cat-studio/interface/ Thu, 04 Apr 2024 14:40:56 +0100 https://docs.justcat.it/reference/cat-studio/interface/ Menu # Menu on the left contains links to these pages: Page Description Welcome Welcome screen with tips how to get started and information about upcoming events Project Create new project, open existing project, overview of an open project Data sources Here you define where is the data you want to test Tests Add, edit, run or remove tests from your project Queries Mainly playground - run any query against any of your data source Logs If anything goes wrong (such as connectivity to database) you can get details about it here Variables Only visible when enabled on Settings page. https://docs.justcat.it/reference/cat-studio/project/ Thu, 04 Apr 2024 14:40:56 +0100 https://docs.justcat.it/reference/cat-studio/project/ This page differs significantly when you have no project and when you have an open project. No Project # You do not have any project open: Because CAT organizes tests in project, you need one. You have these options: create a completely new, empty project open an existing project (in CAT you save projects to .cat.yaml files) open one of your recent projects, if any open a project that you marked as favorite using the Star button https://docs.justcat.it/reference/cat-studio/data-sources/ Thu, 04 Apr 2024 14:40:56 +0100 https://docs.justcat.it/reference/cat-studio/data-sources/ List of Data Sources # CAT Studio needs to know what data you need to test. On this page you define where the data is. When you hover a data source, you see action buttons for editing and removing the data source. Data Source Dialog # When you add a new data source or edit existing one, you work with a dialog with three steps: 1. Give Your Data Source a Friendly Name # Here provide a friendly name for your data source. https://docs.justcat.it/reference/cat-studio/tests/ Thu, 04 Apr 2024 14:40:56 +0100 https://docs.justcat.it/reference/cat-studio/tests/ Tests Page Structure # Tests page displays quite a lot of things. In general, the page is split to two parts - left contains list of tests and right detail of one test. There is a splitter between the two, you can choose whether you focus on list of tests or on detail of one of them. List of Tests # List of tests has this structure: The toolbar contains action related to more tests. https://docs.justcat.it/reference/cat-studio/queries/ Thu, 04 Apr 2024 14:40:56 +0100 https://docs.justcat.it/reference/cat-studio/queries/ On Queries tab, you can run any query against any data source you defined. The page has two use-cases. Playground # You can use queries tab as a playground, where you issue queries against your data sources and check the data you are about to test. You can give your queries names and descriptions. Once you want to turn one of your queries into an automated test, you can use “Make it a Test” button. https://docs.justcat.it/reference/cat-studio/variables/ Thu, 04 Apr 2024 14:40:56 +0100 https://docs.justcat.it/reference/cat-studio/variables/ First, to even see Variables page, you need to go to Settings page in CAT Studio and enable usage of variables: Introduction # CAT supports usage of environment variables in its configuration files. They are supported in data source definitions and in test definitions, in value of any property. Example: When you define environment variable CAT_MyProject_MyVariableName, you can use %CAT_MyProject_MyVariableName% in any property of data source definition or test definition and CAT will automatically pick up its value. https://docs.justcat.it/reference/cat-studio/settings/ Thu, 04 Apr 2024 14:40:56 +0100 https://docs.justcat.it/reference/cat-studio/settings/ On settings page you manage settings of CAT Studio itself - interface, license key, settings common for all projects. If you need to manage settings of a specific project, go to Project page. CAT Studio settings page looks like this: Feedback # Provide us Feedback button will redirect you to CAT Portal page where you can provide us feedback: generic feedback (like it, dislike it) bugs reports feature request Your feedback is highly appreciated. https://docs.justcat.it/reference/cat-studio/keyboard-shortcuts/ Wed, 03 Dec 2025 09:40:56 +0100 https://docs.justcat.it/reference/cat-studio/keyboard-shortcuts/ You can also download PDF version.
