[Question] Give tree to ts-morph

[meliecool]

Hi,

Not sure it is the place for it, but I don't know if there is a possibility to give a tree to ts-morph. I don't find any documentation for tests and I know some issues are open about it, but if it would be possible to give a mock tree to ts-morph, instead of it taking the tree of the workspace by default, it would greatly help!

For more context, I'm using nx and create a fake tree with it to not test my repository, but only my fake tree.

Something like:

import { createTree } from '@nx/devkit/testing';
import { Project } from 'ts-morph';

const tree = createTree();

const project = new Project({ customTree: tree });
project.addSourceFileAtPath('any/file/path.ts');
