Functional tests involve making HTTP requests against the running application and verifying the resultant behaviour. Grails does not ship with any support for writing functional tests directly, but there are several plugins available for this.

Consult the documentation for each plugin for it's capabilities.

Common Options

There are options that are common to all plugins that control how the Grails application is launched, if at all.

inline

The -inline option specifies that the grails application should be started inline (i.e. like run-app).

This option is implicitly set unless the baseUrl or war options are set

war

The -war option specifies that the grails application should be packaged as a war and started. This is useful as it tests your application in a production like state, but it has a longer startup time than the -inline option. It also runs the war in a forked JVM, meaning that you cannot access any internal application objects.

grails test-app functional: -war

Note that the same build/config options for the run-war command apply to functional testing against the WAR.

https

The -https option results in the application being able to receive https requests as well as http requests. It is compatible with both the -inline and -war options.

grails test-app functional: -https

Note that this does not change the test base url to be https, it will still be http unless the -httpsBaseUrl option is also given.

httpsBaseUrl

The -httpsBaseUrl causes the implicit base url to be used for tests to be a https url.

grails test-app functional: -httpsBaseUrl

This option is ignored if the -baseUrl option is given.

baseUrl

The baseUrl option allows the base url for tests to be specified.

grails test-app functional: -baseUrl=http://mycompany.com/grailsapp

This option will prevent the local grails application being started unless -inline or -war are given as well. If you want to use a custom base url, but still want to test against the local Grails application you must specify one of either the -inline or -war options.
