如何使用Espresso检查EditText的字体大小,高度和宽度?
How could I check the font size, height, and width of an EditText with Espresso?
此刻我要使用的文本:
onView(withId(R.id.editText1)).perform(clearText(), typeText("Amr"));
并阅读文字:
onView(withId(R.id.editText1)).check(matches(withText("Amr")));
推荐答案
由于Espresso默认不支持任何这些匹配器,因此您将必须创建自己的自定义匹配器.
You will have to create your own custom matchers since Espresso does not support any of these matchers by default.
幸运的是,这很容易做到.看一下此示例中的字体大小:
Luckily this can be done quite easily. Take a look at this example for font size:
public class FontSizeMatcher extends TypeSafeMatcher<View> {
private final float expectedSize;
public FontSizeMatcher(float expectedSize) {
super(View.class);
this.expectedSize = expectedSize;
}
@Override
protected 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);
}
}
然后创建一个这样的入口点:
Then create an entrypoint like so:
public static Matcher<View> withFontSize(final float fontSize) {
return new FontSizeMatcher(fontSize);
}
并像这样使用它:
onView(withId(R.id.editText1)).check(matches(withFontSize(36)));
对于宽度&高度可以用类似的方式完成.
For width & height it can be done in a similar manner.
