It seems that you are only putting httpclient-4.5.9.jar in your classpath, but it has dependencies on other JARs itself. Most importantly, it depends on HttpCore, part of the same project. You can see the dependencies, and their own dependencies, recursively, at https://mvnrepository.com/artifact/org.apache.httpcomponents/httpclient/4.5.9. Collecting all the transitive dependencies for Java projects manually can become quite time-consuming. You can definitely do it for this test, but I recommend learning how to use Maven.
