**[Tibor Digana](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=tibor17)** opened **[SUREFIRE-1213](https://issues.apache.org/jira/browse/SUREFIRE-1213?redirect=false)** and commented

Introduce MOJO phase pre-integration-test and post-integration-test.
Introduce JSR 223 miscellaneous scriptables (BashShell, JavaScript, Nashorn). The goal is to run environment setup and cleanup before/after integration tests.
For the sake of Surefire build already requires JDK 6 (javac 1.5 still used) these two MOJOs will be added as experimental implementations of Surefire 3.0 which will be built on the top of Java 1.6.

Start by reading the SUREFIRE-1213 description and the Maven lifecycle context for the proposed pre-integration-test and post-integration-test MOJOs. Then investigate the JSR 223 scriptable implementations named in the issue, including BashShell, JavaScript, and Nashorn; done means providing environment setup and cleanup around integration tests while preserving the stated Java-version constraints.
