It's actually pretty simple to check links. All you need to do is find the link on the page, extract a URL from its href attribute, and then check to see if sending an HTTP GET request to that URL results in a valid response.

<properties> <commons-io.version>2.6</commons-io.version> <httpclient.version>4.5.5</httpclient.version></properties><dependency> <groupId>org.apache.httpcomponents</groupId> <artifactId>httpclient</artifactId> <version>${httpclient.version}</version> <scope>test</scope></dependency><dependency> <groupId>commons-io</groupId> <artifactId>commons-io</artifactId> <version>${commons-io.version} ...
