A syntax test must contain at least the contract under test itself, followed by the seperator ``----``. The additional comments above are used to describe the
expected compiler errors or warnings. This section can be empty in case that the contract should compile without any errors or warnings.
The comments in the contract above are used to describe the expected compiler errors. The state variable ``variable`` was declared twice, which is not allowed.
This will result in a ``DeclarationError`` stating that the identifer was already declared.
In the above example, the state variable ``variable`` was declared twice, which is not allowed. This will result in a ``DeclarationError`` stating that the identifer was already declared.
The tool that is being used for those tests is called ``isoltest`` and can be found under ``./test/tools/``. It is an interactive tool which allows
editing of failing contracts using your prefered text editor. Let's try to break this test by removing the second declaration of ``variable``:

``isoltest`` offers several options for failing tests:
- edit: ``isoltest`` will try to open the editor that was specified before using ``isoltest --editor /path/to/editor``. If no path was set, this will result in a runtime error. In case an editor was specified, this will open it such that the contract can be adjusted.
- update: Updates the contract under test. This will remove the annotation which contains the exception not met and runs this test again.
- update: Updates the contract under test. This will either remove the annotation which contains the exception not met or will add missing expectations. The test will then be run again.
- skip: Skips the execution of this particular test.
- quit: Quits ``isoltest``.
Automatically updating the test above will change it to
