Android。 Espresso:如何编写测试检查文本是否在 TextView 上加下划线?
Android. Espresso: How write test check is text is underlined on TextView?
这是我的 xml 布局:
<TextView
android:id="@+id/forgotPasswordTextView"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginBottom="15dp"
android:gravity="center"
android:onClick="@{ () -> presenter.doForgotPassword()}"
android:text="@string/forgot_password"
android:textColor="#bbbbbb"
android:textSize="13sp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="@+id/loginTextView"
app:layout_constraintStart_toStartOf="@+id/loginTextView" />
这里@string/forgot_password
<string name="forgot_password"><u>Forgot password?</u></string>
作为带下划线的结果文本。不错
但我想编写 Espresso 测试来检查 TextView 中的文本是否有下划线?我该怎么做?
如果是 Espresso 测试,则只需创建一个新的匹配器,如下所示:
public static Matcher<View> withUnderlinedText() {
return new BoundedMatcher<View, TextView>(TextView.class) {
@Override
protected boolean matchesSafely(TextView textView) {
CharSequence charSequence = textView.getText();
UnderlineSpan[] underlineSpans = ((SpannedString) charSequence).getSpans(0, charSequence.length(), UnderlineSpan.class);
return underlineSpans != null && underlineSpans.length > 0;
}
@Override
public void describeTo(Description description) {
}
};
}
并按如下方式使用它:
onView(withId(R.id.forgotPasswordTextView)).check(matches(withUnderlinedText()));
