Emacs版本 25.1.1

所有emacs源文件都位于文件夹中：... \ emacs \ share \ emacs \ 25.1 \ lisp \

假设我在Emacs文件打开url.el。在此文件中具有url-retrieve函数。我如何找到（使用emacs）还有另一个* .el文件使用此功能？

谢谢。

我想测试http请求/响应。所以我使用WireMock。

我想存根特定请求的响应：这里代码：

 public class WireMockPersons {

    @Rule
    public WireMockRule wireMockRule = new WireMockRule(8089);

    @Test
public void exactUrlOnly() {
    stubFor(get(urlEqualTo("/some/thing"))
            .willReturn(aResponse()
                .withHeader("Content-Type", "text/plain")
                .withBody("Hello world!")));

    assertThat(testClient.get("/some/thing").statusCode(), is(200));
    assertThat(testClient.get("/some/thing/else").statusCode(), is(404));
}

代码未编译，因为没有对象testClient。如何获取testClient对象？

这里是 XML：

<TextView
            android:id="@+id/toolbaTitleTextView"
            style="@style/textViewOneLine"
            android:layout_width="0dp"
            android:layout_height="0dp"
            android:textAllCaps="true"
            android:textColor="@android:color/black"
            android:textSize="13sp"          
           />

我需要编写 Espresso 测试检查TextView 的字体大小（以SP为单位）= 13。

所以这里测试一下：

@Test
    public void toolBarTextSize() {
        onView(withId(R.id.toolbaTitleTextView)).check(matches(withFontSize(13)));
    }

这里匹配器：

public static Matcher<View> withFontSize(final float expectedSize) {
        return new BoundedMatcher<View, View>(View.class) {

            @Override
            public boolean matchesSafely(View target) {
                if (!(target instanceof TextView)) {
                    return false;
                }
                TextView targetEditText = (TextView) target;
                return targetEditText.getTextSize() == expectedSize;
            }

            @Override
            public void describeTo(Description description) {
                description.appendText("with fontSize: ");
                description.appendValue(expectedSize);
            }
        };
    }

但我收到错误，因为大小以像素 …
