Maven Failsafe Plugin
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:
pre-integration-test
for setting up the integration test environment.integration-test
for running the integration tests.post-integration-test
for tearing down the integration test environment.verify
for checking the results of the 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:
- Plain text files (
*.txt
) - XML files (
*.xml
)
By default, these files are generated in ${basedir}/target/failsafe-reports/TEST-*.xml
.
The schema for the Failsafe XML reports is available at Failsafe XML Report Schema.
For an HTML format of the report, please see the Maven Surefire Report Plugin.
By default this plugin generates summary XML file at ${basedir}/target/failsafe-reports/failsafe-summary.xml
and the schema is available at Failsafe XML Summary Schema.
Goals Overview
The Failsafe Plugin has only two goals:
- failsafe:integration-test runs the integration tests of an application.
- failsafe:verify verifies that the integration tests of an application passed.
Usage
General instructions on how to use the Failsafe Plugin can be found on the usage page. Some more specific use cases are described in the examples listed below. Additionally, users can contribute to the GitHub project.
In case you still have questions regarding the plugin's usage, please have a look at the FAQ and feel free to contact the user mailing list. The posts to the mailing list are archived and could already contain the answer to your question as part of an older thread. Hence, it is also worth browsing/searching the mail archive.
If you feel like the plugin is missing a feature or has a defect, you can file a feature request or bug report in our issue tracker. When creating a new issue, please provide a comprehensive description of your concern. Especially for fixing bugs it is crucial that the developers can reproduce your problem. For this reason, entire debug logs, POMs or most preferably little demo projects attached to the issue are very much appreciated. Of course, patches are welcome, too. Contributors can check out the project from our source repository and will find supplementary information in the guide to helping with Maven.
