The Failsafe Plugin is designed to run integration tests while the Surefire Plugin is designed to run unit tests. The name (failsafe) was chosen both because it is a synonym of surefire and because it implies that when it fails, it does so in a safe way.
The Maven lifecycle has four phases for running integration tests:
If you use the Surefire Plugin for running tests, then when you have a test failure, the build will stop at the integration-test phase and your integration test environment will not have been torn down correctly.
The Failsafe Plugin is used during the integration-test and verify phases of the build lifecycle to execute the integration tests of an application. The Failsafe Plugin will not fail the build during the integration-test phase, thus enabling the post-integration-test phase to execute.
NOTE: when running integration tests, you should invoke Maven with the (shorter to type too)
mvn verify
rather than trying to invoke the integration-test phase directly, as otherwise the post-integration-test phase will not be executed.
The Failsafe Plugin generates reports in two different file formats:
By default, these files are generated at ${basedir}/target/failsafe-reports.
The schema for the Surefire XML reports is available at Surefire XML Report Schema.
For an HTML format of the report, please see the Maven Surefire Report Plugin.
The Failsafe Plugin has only two goals:
