程序运行时包未激活

Question

我为Atom创建了一个名为quick-fold的程序包，该程序包跳到下一个可折叠的行，并在命令quick-fold:fold-next上将其折叠。我想开始了解Atom规范，以便可以对此程序包进行测试，但是我遇到了这个问题，即在运行规范时永远不会激活该程序包。

quick-fold-spec.js：

describe('QuickFold package', () => {

    let editor, editorView;

    beforeEach(async () => {
        await atom.packages.activatePackage('language-javascript');
        await atom.workspace.open('sample.js');

        editor = atom.workspace.getActiveTextEditor();
        editorView = atom.views.getView(editor);
    });

    describe('when the specs are run', () => {
        it('opens the sample file', () => expect(!editor.isEmpty()).toBe(true));
        // true
    });

    describe('when the quick-fold:fold-next event is triggered', () => {
        beforeEach(async () => {
            // Try to activate package by dispatching command:
            atom.commands.dispatch(editorView, 'quick-fold:fold-next');
            await atom.packages.activatePackage('quick-fold'); // Never resolves
        });

        it('activates the package', () => {
            expect(atom.packages.isPackageActive('quick-fold')).toBe(true);
        });

        it('moves the cursor to a different line number', () => {
            expect(editor.getCursorScreenPosition().row).not.toBe(0);
        });
    });
});

但是atom.packages.activatePackage('quick-fold')从未解决。该软件包不会激活，而是超时：

timeout: timed out after 5000 msec waiting for spec promise to resolve

激活命令在package.json中设置：

  "activationCommands": {
    "atom-workspace": "quick-fold:fold-next"
  },

因此，分派这应该激活程序包，然后await atom.packages.activatePackage('quick-fold')应该解决。但是光标位置不会改变，并且程序包不会被激活。

（（请注意，atom.packages.activatePackage('quick-fold')只是一个承诺-它不会激活程序包，但会在激活程序包时解决。）
