# 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:

![Buttons for creating or opening a project](no-project.png)

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


When you hover a file, you can also remove it from the list using this button:

![Button for removing the file from list of recent](remove-recent.png)

This will NOT remove the file from the disk, only from the list of your recently open files.


## Open Project

When you create a new project or open an existing one, CAT shows high-level overview of what your project contains.

Part   | Description
------ | -----------------------------------------------
(1)    | Charts with overview of your project. To what test suites you split your tests, how many there are in each, what data sources are most used in tests
(2)    | Overview of what data sources you have in the project. You can also add / edit / remove them from here
(3)    | Overview of outputs you want - on the example screenshot the test results will be available in JSON and MS Excel file and SQL Server table.
(4)    | Settings of your project - run tests in sequentially (1 thread) or in parallel (more than 1 thread)

The charts are displayed only when you have at least one test in your project.

Do not confuse project settings (on this page) with CAT Studio settings (in the menu).
