/**
 * Helper for setting up everything needed for the schematic tests.
 * It creates things like the TempScopedNodeJsSyncHost and exposes everything and
 * registers the beforeEach and afterEach hooks for jasmine.
 *
 * It also gives you access to functions:
 * + writeFile: makes it possibble to write to the tempFileSystemHost and also updates the hostTree
 * + syncTreeToFileSystem: syncs the whole app tree to the disk
 * + runMigration: call to run the schematic name you specified in the constructor
 * @example
 * ```ts
 * describe('my schematic tests', () => {
 *   const testSetup = new SchematicTestSetup('01-my-schematic-name');
 *
 *   it('should do something', async () => {
 *     testSetup.writeFile('/index.ts', `
 *       import {Foo} from '@aposin/ng-aquila';
 *
 *       export class TestClass {}
 *     `);
 *
 *     await testSetup.runMigration({ project: 'aquila-testing' });
 *     expect(something).toBeTruthy();
 *   });
 * });
 *```
 *
 * You can also use destructuring to get the methods for some cleaner code:
 * const testSetup = new SchematicTestSetup('01-my-schematic-name');
 * let { writeFile, runMigration, warnOutput } = testSetup;
 *
 * WARNING: it doesn't work on properties like runner or appTree as they are undefined
 * at that time
