Robolectric:测试一个Activity,期待额外的内容(版本2.X)

Question

我想测试一个活动,其中一些信息在附加内容中传递.

Intent intent = new Intent().putExtra("someData", "asdfgh");
activity = Robolectric.buildActivity(XYZ.class).withIntent(intent).create().get();

它抛出以下错误:

java.lang.NullPointerException

我的问题在某种程度上类似于此.但是,答案似乎已经过时了.它在旧版Robolectric中运行良好.

Answer 1

这个答案似乎对我有用.但是,有人可以确认这是正确的做法.因为在以前的版本中new Intent().putExtra(String, String)使用起来很好.

这就是我做的:

Intent intent = new Intent(Robolectric.getShadowApplication().getApplicationContext(), XYZ.class);
intent.putExtra("foo", "bar");
XYZ xyz = Robolectric.buildActivity(XYZ.class).withIntent(intent).create().get();

您需要将上下文和类(您要测试)作为Intent构造函数的参数传递.希望能帮助到你.

对于Roboelectric版本3.1+

withIntent(intent) 不推荐使用方法,因为文档意图应该通过构造函数传递.

Robolectric.buildActivity(XYZ.class, intent).create().get();

Answer 2

在robolectric 3.x中,获取应用程序上下文的方式有点不同:

        Intent intent = new Intent(ShadowApplication.getInstance().getApplicationContext(),
                ViewTransactionActivity.class);
        intent.putExtra(foo, bar);
        activity = Robolectric.buildActivity(XYZ.class).withIntent(intent).create().get();
