All available projects are placed in the [resources][resources] folder, which contains:
2929
- [projects][projects] consisting of the folders with the project JAR files in them.
3030
- [classes][classes] consisting of the folders — each named after the project and containing the `list` file with the fully qualified class names.
31+
It also may contain an `exceptions` file with the description of the expected exceptions, that utbot should find.
32+
Description is presented in the format: `<class fully qualified name>.<method name>: <expected exception fqn> <another fqn> ...`.
33+
For example, see this [file](src/main/resources/classes/codeforces/exceptions).

### How to add a new project
3336
You should add both the JAR files to the `projects` folder and the file with a list of classes to the `classes` folder.
