Integration test framework for Java and shell script

We have a reporting solution which is based on software components from different third party vendors - JasperReports, Logstash, Elasticsearch and Oracle database. Now we want to build a test framework to test the integration points in our solution. The kinds of files we change are :-

1. Shell scripts
2. Configurations files (xml, jrxml,yml, etc.)
3. Java files

As per my understanding of testing, we should not test the functionality of third-party vendors and instead just test the changes we make and check whether our solution as a whole works fine or not. For this I am looking for best practice and industry standard to build the test suites which has such a variety of components.

So it would be nice if the framework has the capability to test configurations, shell script and Java files and provided a sort of unified report (like we have in case of JUnit test).
