Check Python ASTs against templates

Project description

astcheck compares Python Abstract Syntax Trees against a template. This is useful for testing software that automatically generates or modifies Python code.

Installation:

pip install astcheck

Example use:

import ast, astcheck

template = ast.Module(body=[
    ast.FunctionDef(name='double', args=ast.arguments(args=[astcheck.mkarg('a')])),
    ast.Assign(value=ast.Call(func=ast.Name(id='double')))
])

sample = """
def double(a):
    do_things()
    return a*2
b = double(a)
"""

astcheck.assert_ast_like(ast.parse(sample), template)

Only the parts specified in the template are checked. In this example, the code inside the function, and the assignment target (b) could be anything.

For more details, see the documentation.
