我的综合测试：

exports.testAssertObject = function(assert) {
    console.log(arguments);
    assert.ok(assert, "Assert object exists");
};

在 JPM 中失败TypeError: assert.ok is not a function：

0 of 1 tests passed.
There were test failures...

我假设，与 cfx 不同， jpm 不会将assert 对象作为测试方法参数传递？

如何在异步测试中实现断言并通知“完成”？

JPM（如 cfx）默认情况下不使用 assert 方法运行测试，而是使用旧版本的测试工具来测试它们。使用当前测试工具所需要做的就是添加

require("sdk/test").run(exports);

到您的 trsts 文件，如您链接的单元测试页面上所述。

要获取更新的断言方法列表，请阅读

资源：//gre/modules/commonjs/sdk/deprecated/unit-test.js

测试方法的第一个参数是在此资源中实现的 TestRuner 对象，并具有不同的接口：

尤其是：

  • ok()方法替换为assert()
  • throws()替换为assertRaises(func, predicate, message)（不同的签名）
  • equal()替换为assertEqual()，许多其他方法也以“assert”为前缀
  • done()方法现在也属于 TestRunner（您的测试方法没有第二个参数）以waitUntilDone(timeoutInMs)在 TestRunner 上声明您的方法异步调用
