Mechanism to reset test environment between test cases

Feature Request

Description

Currently, to reset the test environment between test cases, it's necessary to initialize a new test fixture, which is inefficient in that it must completely reload the validation function from disk. Furthermore, it can lead to the code editor being unable to autocomplete the test fixture object's properties if the variable's initialization is done in a beforeEach block. Add a function to the test fixture object that can be used to reset the test environment to a pristine state.

Examples

describe('My new validation function', () => {
  const testFixture = testFixtureMaker.initFromDocumentDefinitions('/path/to/my-doc-definitions.js');

  afterEach(() => {
    testFixture.resetTestEnvironment();
  });

  // Test cases...
});
