VS代码扩展-包括内联输入文档的写入测试

Question

遵循本指南为VS代码编写简单的扩展，并对这些代码进行自动化测试。我需要在当前文档中有一些预期的文本来运行测试。

我找到了一个脚本的这个例子，它打开一个现有的文本文件并使用它作为输入。

相反，我试图针对测试代码本身中的输入和预期结果运行测试。这似乎更有活力和自制力。

以下是我的尝试：

import * as assert from 'assert';

// You can import and use all API from the 'vscode' module
// as well as import your extension to test it
import * as vscode from 'vscode';
import * as taxi from '../../extension';

suite('Extension Test Suite', () => {
    vscode.window.showInformationMessage('Start all tests.');


    test('displayDiagnostics - empty, no summary', async () => {

        let dcoll = vscode.languages.createDiagnosticCollection('taxi');
        const startTime = new Date().getTime();
        const showSummary = false;
        const result: taxi.Result = {
            // eslint-disable-next-line @typescript-eslint/naming-convention
            total_errors: 0,
            // eslint-disable-next-line @typescript-eslint/naming-convention
            total_warnings: 0,
            errors: [],
            warnings: [],
        };
        vscode.workspace.openTextDocument({
            content: 'The quick brown fox'
        })
            .then((doc) => {
                const diags = taxi.displayDiagnostics(result, doc, startTime, showSummary);
                assert.strictEqual(diags.length, 0);
            }, (error) => {
                assert.fail(error);
            });
    });

*等等

openTextDocument似乎几乎可以工作，但我看到警告说“没有活动的文本编辑器”。

我在做测试时做错了什么吗？

这些测试似乎通过了，即使我包含了一个肯定失败的行，例如

                assert.strictEqual(1, 2);

以下是我使用await的简单解决方案。诀窍是给showTextDocument打电话。这会弹出一个编辑器窗口，其中包含一行文本。抄袭而来。

import * as assert from 'assert';

// You can import and use all API from the 'vscode' module
// as well as import your extension to test it
import * as vscode from 'vscode';
import * as taxi from '../../extension';

suite('Taxi for Email Validation Extension Test Suite', () => {
    vscode.window.showInformationMessage('Start all tests.');

    test('displayDiagnostics - empty, no summary', async () => {

        let dcoll = vscode.languages.createDiagnosticCollection('taxi');
        const startTime = new Date().getTime();
        const showSummary = false;
        const result: taxi.Result = {
            // eslint-disable-next-line @typescript-eslint/naming-convention
            total_errors: 0,
            // eslint-disable-next-line @typescript-eslint/naming-convention
            total_warnings: 0,
            errors: [],
            warnings: [],
        };
        const doc = await vscode.workspace.openTextDocument({
            content: 'The quick brown fox'
        });
        await vscode.window.showTextDocument(doc);
        const diags = taxi.displayDiagnostics(result, doc, startTime, showSummary);
        assert.strictEqual(diags.length, 0);

        // See https://stackoverflow.com/questions/44733028/how-to-close-textdocument-in-vs-code
        await vscode.commands.executeCommand('workbench.action.closeActiveEditor');

    });
});
