Description of Patch
The patch provides a test environment to verify the line/column information of the AST. The following lines describe the possibilities of the environment:
The test file specifies the nodes which the AST should contain. It is defined as follows:
<source code from which the AST will be built>
:::<expected AST output>
The section above can be repeated for every new TestCase
The AST output from the visitor is quite big. Also for small source code snippets. Therefore
it is possible to only specify the nodes that you wan't to check and separate them with a semicolon.
A semicolon is also needed when you begin with a new line.
