use of org.hamcrest.TypeSafeMatcher in project double-espresso by JakeWharton.

the class ViewMatchers method hasSibling.

/**

 * This may be particularly useful when a view cannot be uniquely selected on properties such as
 * text or R.id. For example: a call button is repeated several times in a contacts layout and the
 * only way to differentiate the call button view is by what appears next to it (e.g. the unique
 * name of the contact).

 * @param siblingMatcher a {@link Matcher} for the sibling of the view.
